Laboratories and science spaces in general are configured to allow efficient
installation of scientific equipment with a minimum of effort on the part of
scientists and technicians. Benches, shelving, electrical power, water,
communications, tie-down points and storage are provided. A general description
of these items follows.
All power on the ship is generated as 600VAC which is required for the main
propulsion motors. Power for the hotel load, which includes all deck and
scientific equipment, is stepped down 600VAC to 480VAC.
is distributed as:
480VAC, 60 cycle, 800 amp circuit (unregulated)
480VAC, 60 cycle, 50 amp circuits (unregulated)
120VAC, 60 cycle, 20 amp circuits (unregulated)
120VAC, 60 cycle, 15 amp circuits (regulated)
220VAC, 60 cycle, 3 phase, 45kva (unregulated)
220VAC, 60 cycle, 1 phase, 9kva (unregulated)
Groups requiring 220
or 208 volts must notify the Chief Engineer as to amperage, specific voltage,
single or 3-phase and type of transformer connection (delta or wye).
All internal spaces on Knorr are temperature controlled by a centralized
air conditioning and heating system
All scientific laboratories (except the Lower Lab and Scientific Chart Room) and
deck areas are provided with hot and cold fresh water outlets. Faucets are
located at sinks in the lab spaces and the After Hanger. On deck, either faucets
or standpipes are mounted on bulkheads or overheads in areas readily accessible
to portable laboratory vans or work sites.
Sea water from the ship’s fire and sanitary system is available in the Main Lab,
the Wet Lab, Hydro Lab, Upper Lab and both hangers. In the laboratories, the
faucet is adjacent to sinks. Flow rate is 10 GPM.
Uncontaminated Sea Water
Available in the Analytical Lab, 01 Lab and multiple locations in the Main Lab.
The intake is located in the bow as far forward and as deep as possible. The
pump, its impeller and all piping are PVC; pump flow rate is 7 gallons per
minute on the Main Deck with no back pressure. Dual filters to screen out debris
and seaweed are located at the pump. High sea states and bubble entrapment at
the bow can cause the discharge to become aerated; a debubbler is recommended
for instruments sensitive to entrapped gases. To avoid back pressure at the pump
the discharge has constant flow overboard. A garden hose fitting is provided for
attachment of science equipment to tap the flow as needed. Scientists who want
to use micron filters should keep the flow rate in mind.
A Millipore Milli-Q+ distilled water deionizer unit is located in either the
Analytical Laboratory or the aft end of the Main 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.
Available in all deck and laboratory spaces at nominal 90 psi.
Laboratory 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 Unistrut channel for securing equipment. Most bench units 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.
All 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.
Time, navigation, sea surface and meteorological underway data collected by the
extensive science data handling system are displayed on monitors throughout the
ship. Winch readout displays are located at winch control stations and winch
parameters can be added to the underway data displays upon request.
Intercoms (“squawk boxes”) connect all laboratory spaces, the bridge, deck work
areas and winch control stations. Handheld UHF radios are available when needed.
Closed-Circuit Video System
The ship has a closed-circuit video system which allows monitors in the Main and
01 Laboratory spaces and on the bridge to display images obtained from starboard
and aft external Main Deck cameras plus trawl winch monitoring cameras.
