Section 2: Specifications

COMMUNICATIONS: HiSeasNet C-band satellite system, FleetBroadBand back-up system, cellular, VHF, HF radio, SSB voice, GMDSS.  Please see our contacts web page for current phone numbers.

HiSeasNet and FleetBroadBand systems provide limited bandwidth Internet to the ship. Everyone has Internet access, but is limited by a quota system.  There are also public terminals for both science party members and crew members to access the Internet.  Some websites and high bandwidth functionality is disabled to maximize the usefulness of the connection.  FleetBroadBand provides a satellite phone service available for business or emergency needs.

NAVIGATION CAPABILITIES:  JRC JLR-4341 x 2 DGPS as primary navigation and inputs to dynamic positioning, JRC Doppler speed log. Kongsberg DPS-112 DGPS, JRC 3 and 10 cm radars, Kongsberg dynamic positioning system, Kongsberg HiPAP USBL system, scientific MRUs (Seapath 330+, IXSEA PHINS), and 2 Sperry gyros.

SCIENTIFIC EQUIPMENT:  12 kHz Kongsberg EM122 multibeam echosounder that can record depths up to 12,000 meters; providing bathymetry, and sidescan imagery. 40-100 kHz Kongsberg EM712 for shallow (<1,000 m) water multibeam surveys. Knudsen Engineering 3260 3.5/12 kHz singlebeam echosounder sub-bottom profiler.  Turo Quoll XBT system used with Sippican Fast Deep XBTs.  Currents are measured by Teledyne RDI 38 kHz, 150 kHz, and 300 kHz broadband/narrowband ADCP.. A Kongsberg EK80 fisheries research sonar with five frequencies (split beam transducers at 18, 38, 70, 120, and 200 kHz). A Kongsberg K-Sync acoustic synchronization unit with 8 channels. Kongsberg Seapath 330+ motion sensor. Kongsberg HiPAP 501 (30 kHz, range to 4,000 m) and HiPAP 101 (12 kHz, range to 10,000 m). A comprehensive MET system has several sensors on the forward and main masts for meteorological data, and sensors in the bow thruster room and hydro lab for underway seawater data. (See more in the INFORMATION SYSTEMS AND DATA ACQUISITION in section 4.)

Wired and wireless ethernet as well as a point-to-point serial network (SIS - Science Information System) exists.  Ethernet and serial feeds are available in the science laboratory spaces.

For computer capabilities, see INFORMATION SYSTEMS AND DATA ACQUISITION in section 4.

The ship has a fine-adjust temperature-controlled laboratory to facilitate chemical analyses, and two temperature-controlled walk-in chambers for sample storage/preparation.

Use of isotopes is prohibited in ship's laboratories. Isotope isolation vans are available by request.

An extensive inventory of instrumentation and technical services is available, see section 5. A user fee to recover expenses for operating supplies, calibration, maintenance and repair is typically charged for each of these.

SUPPORT EQUIPMENT: Main crane, Allied TK70-70 on 01 deck. Telescoping knuckleboom, 10,000 lbs at 70 feet extension (sea state 4), 22,000 lbs at 70 feet (sheltered ops). Portable crane, Allied TK4-30 telescoping knuckleboom, 2,000 lbs at 30 feet extension. Normally carried on 01 deck forward, other locations possible to suit mission. Rescue boat davit is an Allied D6700FCTS located on the 02 deck.

Extensive bolt-down fittings for securing removable equipment on the main deck and inside laboratories (2' X 2' pattern).  1” sockets outside, 1/2” sockets inside.

Uncontaminated seawater supply to main lab.

Through-hull instrument well just aft of the outer stairwell from the main deck to the focsle deck, nominal 24" diam. tube.

VANS: Up to 4 vans can be carried, on the port side main deck, 2 across. The other 2 could be stacked, with access from the focsle deck.
WINCHES: CTD/hydro winches: Dual Markey CAST6 with motion compensation and rend & recover modes, each with rated full drum capacity of 14,000 m 0.322” electro-mechanical (EM) cable, 12,000 m 0.375” 3x19 torque-balanced wire rope, or 10,000 m 0.393” electro-optical-mechanical (EOM) cable. Usually there’s 10,000 m of 0.322” EM cable on the CTD winch (forward) and 10,000 m of ⅜” 3x19 wire on the hydro winch (aft). Wires lead over starboard side via Allied crane articulating booms.

Markey traction winch with rated line pull 25,000 lbs at 45 m.min and dual storage drums, each with rated full capacity of 12,000 m 9/16” 3x19 torque-balanced wire rope, 10,000 m 0.680” EM cable, or 10,000 m 0.681” EOM cable. Capable of fiber optic cable through A-frame. Normally there’s 0.681” fiber optic cable on one drum and 9/16” 3x19 trawl wire on the other. Wires lead to A-frame.

Assorted portable winch and wire combinations available for cruise-specific requirements.
