R/V Atlantis Lab Features & Facilities
Laboratories and science spaces in general are configured to allow
efficient installation of scientific equipment with a minimum of
effort. Benches, shelving, electrical power, water, communications,
tie-downs and storage are provided. A general description of these
Inside the labs 120VAC and 240VAC outlets are plentiful. On
deck a limited number of 480VAC plugs are availble. Any science
team that desires to use the external 480VAC plugs should
contact WHOI in advance to coordinate power needs, since these
plugs are also used for portable deck cranes, etc. Up to 600kw
of non-propulsion power is available. All power on the ship
is generated as 600VAC which is required for the main propulsion
motors. A ship’s UPS carries vital loads, including
the ship’s data system. Several smaller UPS’s
are available for use in various labs to protect science team
equipment from power losses.
Electrical power is distributed throughout the ship as:
- 480VAC, 60 cycle, 50 amp circuits
- 120VAC, 60 cycle, 20 amp circuits
- 120VAC, 60 cycle, 15 amp circuits
Experience has shown ship’s power to be stable and
reliable. However, all ship’s service power has the
potential of being contaminated by transients associated with
running machinery and spiking introduced by SCR firings from
the main propulsion motors. Scientific instrumentation which
is sensitive to transients should be operated off the “clean”
power bus. Clean power is 120VAC generated by an M-G set to
isolate the circuit from sources of electrical transients.
A maximum of 30kw is available. Clean power is available in
all laboratory spaces in plug strips clearly marked as such. Uninterrupted Power Supply (UPS) units are provided in laboratory
spaces. All units operate from regulated 120VAC power supplies.
All internal spaces on Atlantis are temperature controlled
by a centralized air conditioning and heating system.
Fresh WaterAll scientific laboratories (except the Electronics/Computer
Lab) and deck areas are provided with hot and cold fresh water.
Faucets are located at sinks in the lab spaces. On deck, either
faucets or standpipes are mounted on bulkheads or overheads
in areas readily accessible to portable laboratory vans or work
Sea water from the ship’s fire and sanitary system is
available in the Main Lab, the Wet Lab, Hydro Lab, and Bio/Analytical
Lab. In the laboratories, the faucet is adjacent to sinks.
Uncontaminated Sea WaterAvailable in the Main, Bio/Analytical, Hydro and Wet Labs. The
intake is located in the bow (as far forward and as deep as
possible). The pump, its impeller and all piping are PVC lined.
Flow rate is 50 gallons per minute. Dual filters to screen out
debris and seaweed are located at the pump suction. High sea
states and bubble entrapment at the bow can cause the discharge
to become aerated. Though a vent is provided in the system,
a debubbler is recommended for instruments sensitive to entrapped
gases. The system continuously discharges overboard. Seawater
temperature and conductivity probes are permenantly mounted
at the pump suction and are tied to the ships data system.
Deionized WaterA Millipore Milli-Q+ distilled water deionizer unit is located
in the aft end of the Hydro Laboratory. The water source for
the deionizing filter unit is a 30-gallon stainless steel head
tank located on the 01 Level. This tank is periodically filled
with water obtained from the ship’s distillation plant.
Compressed AirAvailable in all deck and laboratory spaces at nominal 90 psi.
BenchesLaboratory benches are provided in all laboratories. Most benches
are a standard 8 feet long x 32 inches wide x 36 inches high.
The tops are provided with lips and tie-down devices for securing
equipment. Most benches are fitted with a full storage shelf
below. All benches are portable, capable of being rearranged
as needed to meet individual project space configurations. Book
shelves are also provided in all lab spaces.
Tie-downsAll laboratory and deck spaces are provided with means for securing
equipment at sea, known collectively as tie-downs. Laboratory
decks are fitted with 3/8" bolt receptors locator on 2' x 2'
centers. All overhead and bulkhead surfaces are equipped with
"UniStrut" channels on 2' centers. External deck surfaces are
all fitted with recessed stainless steel bolt receptors on 1'
x 2' centers.
DisplaysWinch readout displays are provided at winch control stations
on the 01 Level, inside the Winch Control Tower (Doghouse),
on the Bridge, and in the Computer Lab at the winch control
station. Data from the science data handling system is displayed
on monitors in various labs.
Internal CommunicationsAn intra-ship telephone system connects all the spaces in the
ship. Handheld UHF and/or VHF radios are available when needed.
