AFTER STEERING - All conning of the
ship is done from the bridge, since the configuration of Melville's
superstructure allows all on-deck operations to be viewed from one or another
of the bridge wings. Auxiliary controls are mounted in each wing so that the
helm may be monitored at any of three locations within the pilothouse.
AIR, COMPRESSED - (See Compressed
Air)
AIR CONDITIONING AND HEATING - Internal
temperatures are regulated with thermostats. Each stateroom also has individual
thermostats. The lab air conditioning is tied into the A/C system for the
entire ship.
BIOLOGICAL SAMPLING - (See also Chief
Scientist's Manual) A limited suite of biological sampling equipment can
be provided on board Melville. This includes an Isaacs-Kidd midwater
trawl (10' mouth), a 1 meter plankton net, a 1 meter neuston net, a 10' Otter
trawl, and assorted dip nets. Contact the resident technicians regarding this
equipment. Sample storage bottles, labels, preser-vatives, sorting apparatus,
microscopes, etc. are not stocked, and are the responsibility of interested
investigators.
BOATS - A Boston Whaler (10') is normally carried
by Melville as a work boat. Specific requests should be made to the
marine superintendent prior to departure of the ship from San Diego, to insure
a boat meeting your requirements is available. At sea the crew controls launching,
operation and recovery of boats.
BOATSWAIN LOCKER - There is a rigging locker
on the main deck: the main boatswain's locker is located all the way forward.
These lockers contain hardware and supplies utilized by the crew in the maintenance
of the ship. These lockers also contain portable securing devices, such as
cleats and eyebolts, for use with the 2' deck bolt down pattern. The resident
technician or a crew member will assist you in their use if necessary.
BULKWARK DOORS - Several sections of the fantail
bulwarks are capable of being removed, to permit loading and handling of large
and/or heavy objects. Requirements for the removal of bulwark sections should
be discussed in advance with the marine superintendent or the captain.
CABLE RACEWAYS - Raceways run between labs and
from the labs to the fantail. Do not disturb existing wiring and remember
to remove yours at the end of your cruise.
CAPSTANS - There is normally a large capstan
on the fantail, on the center line, immediately aft of the after hangar. A
second portable capstan may be positioned on various locations about the deck.
CHEMICALS - Use care in storage, handling, and disposal
of toxic chemicals, particularly inside laboratories. All chemicals brought
on board should be accompanied with a Material Safety Data Sheet (MSDS) provided
by the chemical manufacturer. Plastic bottles are safer at sea and should
be used unless specific chemicals must be stored in glass. Disposal of chemicals
should in general be directly overboard, not into ship plumbing. The ship's
captain must know what chemicals you are carrying. A chemical storage locker
is available and is the only safe way to carry most chemicals aboard ship.
Please make arrangements with the resident technicians in advance for proper
stowage.
CLEAN POWER - (See Electrical
System)
COMPUTER - Two Sun 600 servers running UNIX
file system are permanently installed in the ship's computer room. A computer
engineer to support them and the other standard data acquisition equipment
is normally aboard on all cruises. Each Sun 600 server includes 4 internal
CPU's, 128-Mbytes of memory, a 1.3-Gbyte disk, a 2-Gbyte disk, a 2.4-Gbyte
disk, a CD-ROM, a 4mm DAT tape drive, an 8mm Exabyte tape drive, a 9-track
read 800 bpi read/write 1600/6250 pbi tape drive, 16 dedicated high speed
serial ports, two dedicated SCSI ports, two ethernet ports (one to service
the ship's ethernet and one dedicated to SEA BEAM) and one GPIB (IEEE-488)
bus. Various printers and plotters are available in the main lab and computer
lab along with standard ASCII terminals and X-windows terminals. A few IBM
PC/AT clones and Apple Macs are also available. The computer room, main lab,
and computer lab are interconnected by an ethernet backbone and by RS-232
connections. Both AUI transceiver cable taps and thin wire connections are
available for the ethernet in the computer room, main lab and 01 computer
lab. The computer lab has a terminal server for additional serial connections.
10Base-T (twisted pair) connections are also available in the computer lab.
An Ashtech 3DF system is permanently installed to provide very accurate attitude
information. The data is not applied in real-time to any of the instrumentation,
but can be passed on to other systems if required. The data is archived on
the Sun 600 server for post-processing with other data sources. An IMET Meteorological
System is permanently installed that provides wind speed/ direction, relative
humidity, barometric pressure, shortwave radiation, air temperature, sea surface
temperature, and precipitation information. The information is logged on the
Sun 600 server and can be provided to interested users in real-time. The computers
provide an E-mail link via high-speed modem over the ComSat satellites. The
E-mail system used is a store-and-forward facility with typically one connection
being initiated per day. When the chief scientist arrives at the ship, he
or she will complete a form which asks for his E-mail account name. The Shipboard
Computer Group will then set up the E-mail account. The usage of E-mail must
be paid for by the user and covers both incoming and outgoing messages for
each user. Cash or credit cards will not be accepted aboard ship for this
service. The chief scientist is ultimately responsible for charges incurred
but not paid for by individuals in the scientific party. The computer engineer
will send Melville's weekly science report for the chief scientist
at no cost. The Ship Scheduling Office requests that the weekly report be
in their hands by noon on Tuesday. Users aboard ship are normally able to
send messages using the same addressing as ashore. Their addresses while on
the ship will be:
If you have problems sending E-mail, contact the
Shipboard Computer Group for assistance. The computers perform a standard
set of data acquisition and processing functions. This includes the collection
and archiving of various ship's navigation sensors and meteorological and
geophysical data. Data acquisition equipment includes an RDI 150 kHz or 300
kHz acoustic doppler current profiler, a Bell BGM-3 gravity meter, a Sippican
XBT, a SEA BEAM 2000 bathymetric mapping system and a Trimble 4000 AX 10-channel
GPS receiver. The data from these instruments are logged by the computers,
and upon request the data can be made available in near real-time along with
any other routine data that is being archived. Specialized real-time data
acquisition can be done by prior arrangement with the Shipboard Computer Group.
The XBT probes that are carried on the ship are for the calculation of the
sound velocity profile for the SEA BEAM 2000 system and are not available
for other uses although the data can be made available to interested parties.
If a separate XBT program is planned, the chief scientist must provide their
own XBT probes. Use of SEA BEAM 2000 and the Bell gravity meter requires a
separate sub-contract. The current published rates for their use are available
at the SIO's Ship Scheduling Office.
COMPRESSED AIR - Ship's service air is 100
psi at 12 cfm. The upper limit cannot be used continuously. It is suitable
for running pneumatic tools, but it is not clean. Users should plan to supply
their own filters if the air is intended for any lab use. Outlets are at the
same places in the lab as water. Air for airgun reflection operations is provided
by a Price air compressor in the trawl winch room at 2,000 psi, 200-210 cfm. The
ship normally carries one Price air compressor. If larger amounts of air are
necessary, arrangements must be made in advance to carry additional compressors.
If scuba air is needed a small supply is carried in tanks. For larger amounts,
make arrangements before the cruise to carry a special portable compressor
for diving air.
CRANES - The marine superintendent, the chief engineer,
or the resident technician must be consulted concerning all proposed freight
handling. Permission to operate cranes is strictly limited to authorized personnel.
These cranes are operated at sea only by permission of the captain. Pettibone
model TB; located on the 01 deck just aft of the superstructure. Minimum radius
5', maximum radius 60'. Load at minimum radius, 36,000 lbs. Load at maximum
radius, 3,540 lbs. Load figures shown here, in particular for minimum radius,
are static loads with crane fully topped up. Allied crane is located on the
after part of the 01 deck nearly centerline and serves the entire fantail
area. It has a 65' articulated boom. The in-port load limits are 5,000 to
12,000 lbs depending on the distance from the crane base. The at sea limit
is 4,000 lbs at all angles of reach. Small semiportable cranes are also available
and generally are carried on the main deck. They can be placed in various
locations about the deck but cannot be safely relocated once the vessel is
at sea. The minimum reach is about 2', maximum reach is 18'. Maximum load
at all boom angles is 1,500 lbs. The resident technician must be consulted
prior to any use of this crane.
CUSTOMS - Shipping equipment to and from foreign
ports requires the scientist to deal with two sets of customs officers and
rules, theirs and ours. Register your items with U.S. Customs (Form 4455)
first. Check with the consulate or embassy of the foreign country next. Document
and make lists of everything. List the value of each item. Etch or mark serial
numbers on each item. Commercial container shipments are made to and from
R/V Melville as needed during the course of an expedition. Arrangements
from SIO are made by the Resident Technician Group, while arrangements from
the ship are made by the resident marine technician aboard. Cost of commercial
shipments is apportioned to contracts and grants utilizing them.
DAVITS - These are all designed to be portable
and bolt-down, and are positioned according to anticipated research needs.
None of them are power-driven, and the design load limits are in the range
of 1,000 lbs.
DECK LOADING - The weather decks where equipment
may be loaded include the foc'sle, the 02 level and 03 level forward of the
bridge, the 02 level aft of the stack, the 01 level starboard side, above
the forward hangar, the 01 level aft, above the fantail, the quarterdeck,
starboard side and the fantail. The approximate loading is 1/2 ton/sq ft.
All of the spaces listed above, except the foc'sle and 03 level, have deck
tie-down patterns, which must be used in securing gear. Welding directly to
the deck is not permitted. Ship stability is ultimately the responsibility
of the captain. The responsibility of scientists is to consult MarFac or the
resident technician early to describe loading plans and requirements so that
any necessary adjustments can be made. The more complex and heavy your equipment
the more advance notice is needed. Our goal is to resolve problems well before
sailing day, so that it will not be necessary to leave scientific gear on
the dock in order to assure a safe ship.
DECK TIE-DOWNS - No welding is permitted directly
to any deck. All installations must use tie-downs (welding may be done to
'ears' or plates, which in turn are bolted to the deck). Bolt holes are 1"
nc. Bolt holes in equipment should be made 1 1/8", to allow for deck irregularities.
The main deck and 01 level aft have a tie-down pattern of 1' x 2'. The 02
level's pattern, aft is 2' x 2' (this is narrow deck encircling funnel aft
of topside lab). The forward section of 02 level is a 4' x 4' pattern. Foc'sle
and 03 level have no tie-down pattern. 01 level platform above quarterdeck
is a "temporary platform'' for placement of starboard hydro-winch and also
has no tie-downs. Tie-down pattern in laboratory spaces is 2' x 2', holes
are 3/8" nc. Extensive (~3,000) bolt down fittings for removable equipment
are available on all decks and inside laboratories.
DEPTH RECORDING - (See Echosounding)
DISTILLED WATER - (See Fresh
Water)
DOPPLER LOG - A doppler log is installed
for speed measurements. (See Acoustic Doppler
Current Profiler)
DRAINS - (See also Chemicals)
Main lab sinks drain directly overboard. The under-sink areas in the lab should
(1) be carefully inspected before using the sinks to insure that connections
are in fact connected and open, (2) be kept clear of stored items capable
of damaging pvc pipes or blocking drains, and (3) be kept clear of lab trash
and debris.
ECHOSOUNDING - Melville has both 12 kHz and
3.5 kHz echosounding systems for laboratory use, as well as a shallow-water
sounder on the bridge for navigation. It is expected that an echosounder watch
will be maintained whenever the ship is under way, except in areas that are
very well surveyed. The resident marine technician will instruct new personnel
in watch standing procedures, and perform daily maintenance on the equipment.
See the Chief Scientist's
Manual for more details. The suite of equipment includes: two EDO 550
recorders, two EDO 248-E transceivers, two EDO 8 kw power amplifiers for the
3.5 kHz system, a receiving streamer and filter amplifier, an EDO standard
3.5 kHz transducer mounted on the door of the center-well, a set of Harris
transducers for the 3.5 kHz system in a protecting chest inside the fuel tank
under "boys town", one 12 kHz EDO transducer in the bow dome and two in the
skeg. There is an automatic "record annotator" run by the computer.
ELECTRICAL SYSTEM - Permanently installed
lab computer power is 15 kw mg set. The ship has the following power plant
elements :
3 SSDG 1,000 kw 600 vac 3 phase
1 SSDG 550 kw 600 vac 3 phase
2 1,000 kva transformers 600 vac to 480 vac
Various 50 amp 3 phase 480 volts
Various 220 volt 3 phase 30 kva total available
Various 120 volt receptacles
1 400 amp 480 volt stations (normal power for Geologic air compressors)
Lab Clean Power 30 kva mg set
Ship's electronics 30 kva mg set
EXERCISE EQUIPMENT - R/V MELVILLE has
recumbent and normal exercise cycles, Nordic Track, free weights and a stair
climber.
EXPLOSIVES - For information on shooter schedules
and storage of explosives contact the resident technician. The storage and
handling of explosives aboard ship are strictly regulated by the U.S. Coast
Guard and by other agencies. All plans for explosives use must be cleared
well in advance. Submit plans for loading and use of explosives to the Ship
Scheduling Office. Most of the resident marine technicians are qualified explosives
handlers. If, however, there is to be extensive explosives use, a qualified
person in addition to the regularly assigned resident technician must be on
the ship. For information on shooter schedules and storage of explosives and
to obtain USCG permits, contact the resident technician.
FLOOD LIGHTS - Working lights on deck are controlled
by the bridge. Other deck lights and their on-off switches are known to the
resident tech, who will see to it that they work. Consider the night vision
of the crew and use only the lights you need, turning them off when finished.
Hand lamps, flashlights, etc. can be obtained through the resident technician.
Supply is limited; large scientific parties should provide their own units.
FREEZER - (See
Refrigeration and Freezing)
FRESH WATER - Fresh water generation capacity
is 4,000 gals/day. Fresh water is generated in two ways (1) by using waste
heat off the main engine to distill water while underway, and (2) by using
the reverse osmosis water maker. Fresh water production by the R.O. system
has a substantial mineral content. Potable water tank capacity is 15,896 gals.
Distilled water is available off the evaporator but not continuously. There
is no scientific still on board. Fresh water should not be used for wash down
purposes, except if necessary and then by consultation with the resident technicians.
In personal use, conserve. Take sea showers; do only full laundry loads. (See
Section VIII. Ship Organization)
GASES - (See Storage) These are the responsibility
of the individual requiring gases for shipboard use. Any gas under pressure
is dangerous; consult the captain or the resident technician for safe stowage
methods and locations.
GASOLINE - Inspected vessels are severely limited
by law in the amount of gasoline they can carry, unless they have approved
built-in tanks, which R/V Melville does not. Small amounts of gasoline
for outboard motor use at sea are carried in USCG-approved containers. If
larger amounts of gasoline are needed, a special "portable" tank can be placed
aboard--but it must be requested in advance from the resident technician.
GENERATORS - (See Electrical
System)
GEOLOGICAL SAMPLING EQUIPMENT - Gravity coring
equipment, a piston coring suite of equipment, a box corer and rock dredges
are maintained by the Resident
Marine Technician Group. A researcher planning use of any of the above
equipment during an expedition should make this need known during the pre-cruise
conference or before. The size and weight of geologic sampling gear make it
expensive or impossible to ship commercially. Liners of clear butyrate tubing
are used with both gravity and piston corers. This liner deteriorates during
long storage. Each researcher should determine his needs. The Resident Marine
Technician Group can buy a liner, on a recharge basis, gauge it for size and
load it on board before an expedition. Detailed plans for projected use should
be submitted with the longest possible lead time to allow for assured supply
of critical items, such as pipe liner for core barrels, and dredging supplies.
GEOPHYSICAL SAMPLING GEAR - R/V Melville
can be equipped with a wide range of geophysical gear such as a magnetometer,
airguns, reels, recorders and hydrophone streamers. Other related systems
can be made available. These involve wide-angle reflection, refraction, and
single-channel analog and digital reflection. Availability and use of the
equipment, as well as the participation of qualified operating technicians,
must be planned several months in advance of cruise departure. The geophysical
engineer is responsible for the installation, maintenance, and repair of the
echosounding systems and magnetometers installed on SIO vessels. These services
are provided on a cost basis. Contact the Shipboard
Geophysical Group of Shipboard Technical Services for more information
and costs.
GYRO - The ship's gyro has various slaved repeater
units. There are repeaters located in the main and 02 labs, computer room,
and flying bridge to permit monitoring of the ship's course.
HATCHES - (See Internal Well) In addition to cargo
hatches, and manholes, there are watertight doors in all labs and to all weather
decks as well as all the other interior doors, some of them spring-loaded.
Careful use of all doors and hatches, especially at sea, is very important.
Carelessness could easily lead to severe injury.
HOLD - (See Storage)
HYDRAULIC SYSTEM - (See also A-frames, Cranes)
Both side and stern A-frames are hydraulically operated, as are both cranes.
Operating controls for the frames are located on the port side of the stern
frame, forward side of the side frame. Questions regarding user applications
of excess hydraulic capacity should be directed to Nimitz Marine Facility
(the marine superintendent, the port engineer, or the chief engineer on board
Melville) well in advance.
HYDROGRAPHIC BOOMS - (See Winches)
HYDROWINCH - (See Winches)
HOODS - As of this writing, there are no chemical
hoods provided in any of the ship labs or vents for hookups.
INTERNAL WELL - This is an 8' x 10' space
that penetrates from the main deck to the keel, near the center line. It is
closed at the top with a screw-down soft patch, and the original intent was
to mount a drilling rig here--this use has never occurred. It is generally
used for storage. Any intended use of the well to deploy equipment should
be worked out with MarFac well in advance.
INSTRUMENT WELLS - There are four 20"
diameter wells (1) port side, 01 level, (1) starboard side under the starboard
A-frame, and (2) aft just outboard of the stern A-frame legs. Intended use
should be cleared with the captain and the resident technician.
ISOTOPES - (See Radioactive
Material)
INTERCOM - (See Internal Communications, Section
VI. Navigation and Communications Capability)
MAGAZINE - (See also Storage) There is none
on board. Storage of explosive substances has in the past been in fantail
containers prepared for the occasion and dismantled/abandoned afterwards.
There is a U.S. Coast Guard approved converted 20' shipping container for
use as an explosives magazine. It is not normally carried and must be requested
from resident technicians.
MAGNETOMETER - R/V Melville is equipped
with a Geometrics G-886 Marine Proton Magnetometer. The system consists of
the towfish, tow cable, winch, deck lead, deck box, power/data lead-in, and
power supply. The main electronics of the system is in the deck box, which
is located in the crane base, near the winch. The data stream leaving the
deck box is digital (RS-232), and therefore much less susceptible to noise
than older systems. Data is logged to the ship's on-line computer, along with
most other data streams such as Seabeam, IMET, GPS, etc. The data is displayed
in real-time on the watchstander's console. The tuning of the magnetometer,
as well as the logging of the data, is done automatically when the system
is turned on.
MASTS - Melville has two masts, plus the
jackstaff. The main mast is part of the stack assembly and main superstructure.
It is located above the pilothouse, and includes the crow's nest, 2 radar
antennas, ship's whistle, main mast lights, and the ADF antenna in the top
most position. The anemometers are mounted on the foremast platform. The foremast
is at the forward end of the 02 level and is the usual location of temporary
scientific antennas.
PROPULSION - Melville is equipped with twin
"Z" drive shrouded propellers aft, trainable 360 degrees. Propeller speed
is variable from 0 rpm to full. A shrouded bow "Z" drive propeller, similar
to the stern drives, is also available for station work in deep water. The
unit is stowed within the hull behind a flush cover and must be lowered to
operate. The bow propeller cannot be used at faster than maneuvering speeds.
Thrusters can be controlled independently or integrated through a Robertson
Shipmate autopilot system. Dynamic positioning is also available utilizing
GPS or transponder navigation systems. Melville is capable of accurate
station holding in most wind and sea conditions, and is also capable of moving
directly sideways at speeds to 2 kts. For fuller details of handling and maneuvering
characteristics consult the captain.
RADIOACTIVE MATERIAL - The use of radioisotopes,
or other isotopes in concentrations not found in nature, is strictly controlled
aboard Melville Permission to use radioisotopes must be obtained from
the SIO Ship Scheduling Office in writing, following written
application (which is reviewed by the Radioisotope Committee) describing
aims of the work and the isotopes, quantities, and procedures to be employed.
Such usage must be consistent with strict precautions for safety and to prevent
contamination of the ship. All handling of isotopes must be done within a
designated portable isolation van. Vans are available upon request to the
resident technicians; Cleanup costs of any isotope spills will be charged
to the persons responsible. .
REFRIGERATION AND FREEZING - There is no dedicated
built-in refrigerated space available for scientific use. There is a permanently
installed explosion-proof refrigerator in the main lab for science use. The
ship normally carries an 18 cu ft chest freezer for scientific use in the
trawl winch room. The ship's cold storage is NOT available for scientific
use. Portable chest types freezers are available upon request.
SCUBA DIVING - All diving from SIO vessels is controlled
by the Diving Officer. Each diver must have a valid University of California
Certified Diver Card or have been approved by the Diving Officer prior to
every diving operation. Click here
for the Diving Form. When completed, return to the Ship Scheduling Office.
There is no decompression chamber, and no scuba air available on R/V Melville.
A portable scuba air compressor can be supplied by the Diving Office at SIO.
R/V Melville carries a buddy pair set of scuba gear for emergency work
or hull inspection. Researchers should bring their own gear. Not all resident
technicians at SIO are divers, but those that are certified are usually eager
to dive.
SEA BEAM - Melville is outfitted with
the SEA BEAM 2000 multiple narrow beam 12 kHz swath mapping system. It is
under the custody of and operated by the SIO computer and/or electronics engineer.
The system is a 120 degree, hull mounted, 12 kHz transducer system. It produces
both bathymetry, depth and cross-track distance, and side-scan imagery. Its
data are archived on the shipboard scientific computer system and are displayed
in real-time on various devices. These include a 12" continuous feed multiple
pen plotter for the along track swath display, an EDO digital recorder for
side-scan and center-beam displays, CRT displays of side-scan and bathymetry,
and contours overlaid over the ship's track on the real-time DR plotter. Post-processing
programs are available to produce charts aboard ship.
SEAWATER - There are bibs for seawater wash
down at various points on the weather decks. Checking with the deck watch
officer is appropriate before hooking up and using any hoses.
SHEAVES & BLOCKS - Use of various winches
and wires implies use of certain combinations of sheaves and blocks. In addition,
your scientific operation may have particular requirements for fairleading
wires to certain locations, etc. Be sure to check with the resident technician
well in advance to explain all your wire rigging ideas and needs. Never use
a sheave that is too small in diameter for the wire.
SHIPPING - Limited stowage on board R/V Melville
often necessitates shipping equipment and samples. Commercial containers are
arranged by the Resident Technician Group. Shipments can be made to the ship's
agent in ports other than San Diego; contact Marine Facilities for the agent's
addresses. Agents charge for every service they provide. Please try to consolidate
dealings with the agent through either the captain or the resident technician.
Agents should be advised by telegram of waybill numbers so they can arrange
for transportation, storage and customs. Registering of equipment with U.S.
Customs (Form 4455) before shipping outside the U.S. makes return shipping
possible.
SEISMIC REFLECTION - (See Section
V. Technical Services and Special Equipment)
STERN RAMP - This may be utilized in the handling
of large nets, deployment of arrays, etc. The entire ramp is decked over,
when not in use, flush with fantail, by removable, steel plate. It is also
closed across the transom opening by metal plates, to prevent seas from coming
up on deck. The boards and steel plate are not safe to remove at sea. Use
of the ramp for research programs should be worked out well in advance with
the marine superintendent, the captain and the resident technician.
STORAGE - There is one space available for scientific
storage: the lower science hold. It is approximately 475 sq ft, accessible
from the cargo trunk 5' x 5' opening from the 02 level. The cargo trunk has
3' x 5' openings at each deck level. Lab gas storage is on the fantail, in
portable racks for (6) bottles/rack (nitrogen, etc.). Other chemicals, e.g.
formaldehyde, alcohol, acids, etc., have no permanent facility and storage
must be arranged on an item by item basis with the resident technician. The
captain must be apprised in detail of all substances of a hazardous nature;
this includes any materials considered toxic, noxious, flammable or explosive.
SUPPLIES AND EQUIPMENT - On board R/V Melville
the resident technician maintains a tool box from which the scientific party
can borrow tools. Return of all tools is a must. In addition, the resident
technicians maintain a stock of office supplies from which scientific parties
can draw. Both the tool collection and the office supply stock are modest
and limited to commonly used items. It is not possible to stock everything
anyone might conceivably wish to have at sea. Researchers anticipating the
use of, for example, an extensive inventory of chemical lab equipment, should
consult with the resident technician and plan to supply most of their own
needs. Stocking of the ship prior to the beginning of an expedition is done
with the expectation of more or less steady use of the items stocked and,
it is hoped, in sufficient quantity to forestall the need to re-equip in overseas
ports--an unsatisfactory experience in almost every instance. A list of inventoried
supplies is available from the resident technician upon request. Local purchase
of extra quantities of particular items can be arranged through him and should
be done as far in advance of departure as possible. Supplies purchased will
be recharged to the account of the requestor. The ship does not carry a standard
suite of analytical or special use equipment. The planned use of equipment
such as water sampling bottles, reversing thermometers, box corers, bottom
trawls, centrifuges, ovens, or any darkroom equipment should be indicated
on the Ship
Time Request Form, and should be checked in consultation with the resident
technician well in advance (See also Section V. Technical
Services and Special Equipment)
UNCONTAMINATED SEAWATER - Uncontaminated
seawater is provided via a pump in the bow dome at 50 gal/minute. All internal
piping is stainless steel and pvc and there is no holding tank for this water.
There are 3 outlets in the main lab, 2 in the forward and after hangars.
VANS - Melville can carry multiple
laboratory, refrigeration, and berthing vans. Plans to use any vans should
be indicated on the Ship Time Request Form and details should be discussed
with the resident technician well in advance of departure.
WINCHES - The ship is normally outfitted with three
winches: Hydro, CTD and a trawl. A Northern line traction-drum winch with
dual storage drums. Normally 12,800 m of 9/16" 3 x 19 dredge trawl wire is
on one storage drum and 10,000 m of 0.680" electromechanical cable on the
other. It is fed over aft or side A-frame. A small Northern Line hydrographic
winch carries 7,600 m of 1/4" 3 x 19 wire. This winch is lead over the side
amidships via a hydraulically operated J-frame. Melville is also equipped
with a small winch utilized for the towed magnetometer. A Markey DESH-6 CTD
winch carries 10,000 m of 0.322" three-conductor electromechanical CTD cable
on Lebus grooving. It is fed over the side via the side A-frame.
WIND & SPEED DIRECTION INDICATORS - (See Masts)
WIRE - A log is maintained by the chief engineer
documenting the actual wire on each winch at any given time. The working end
of every wire is occasionally cut off and the termination replaced, and this
can sometimes amount to 100 meters or more, if damage has been sustained by
the wire. It is important that expected water depths of planned operations
be made known to the resident technicians and the marine superintendent as
far in advance of these operations as possible, to ensure that adequate wire
is available. Lead times on the purchase of new wires can amount to a year.
