SHIP SYSTEMS__________

Propulsion Electrical System
For flexibility and economy of operation, R/V KILO MOANA is designed with a fully integrated electric system which provides power for both propulsion and ship's service uses. An integrated system is particularly appropriate for a research vessel where demands can vary from very low to near maximum depending on the operation being conducted. The four generators are distributed among two generator rooms, one of which is located on each side of the ship. The plant is designed for a speed of 15 knots at 100% power and 12 knots at 63% power. The machinery plant is designed for unattended operation in accordance with regulatory body requirements and provides for Pilot House and Main Control Station (MCS) throttle control over the complete range of plant operation.

Auxiliary Systems
Pump rooms are located forward and directly under the generator rooms. Two auxiliary machinery rooms are located inboard of the generator rooms to contain auxiliary machinery. Fuel handling equipment is segregated in Auxiliary Machinery Room #2. The Switch Gear Room is located directly below and forward of the Emergency Generator Room. The air conditioning system is a distributed chilled water system with individual fan coil units located in each space.

Propulsion Equipment
Four 910 kW diesel generator sets driven by Caterpillar 3508B SCAC diesel engines
Two DC main propulsion motors--Westinghouse Class 3 rated at 1.5MW fed by 12-pulse silicon controlled rectifiers (SCRs) and  phase shifting transformers

Elliott White Gill Model 40 Bow Thruster--located in starboard hull

EDI power management and control system which provides highly detailed monitoring and automatic control of the ship's engineering function

SHIP CONTROL__________

The ship is driven by two fixed pitch propellers with conventional rudders located behind. The propellers are designed for "cavitation free" operation at 12 knots. Aft fixed stabilizers and forward adjustable canards are provided to adjust ship trim and dampen pitching motion. A single azimuthing jet-type bow thruster is located forward in the starboard hull. The bow thruster also allows the vessel to two 10,000 lbs at 3 knots with the main propellers secured to reduce the likelihood of tow line fouling. The ship is designed to precisely hold position in seas up to 6 meter significant wave height and a wind speed of 47 knots at best heading. The ship is also designed to follow a trackline over the bottom at best heading at any speed up to 12 knots with constant towing load of 10,000 lbs.

R/V KILO MOANA incorporates a sophisticated dynamic positioning system (DPS) which accepts data input from position and environmental sensors and automatically controls propulsion and steering to perform precise maneuvers. Automatic maneuvers include steering a fixed heading, holding position at a designated location, following a trackline over the bottom, or moving from one position to another. The system also allows manual control by means of a joystick. The Pilot House main console serves as the primary control, with secondary control located in the Computer Laboratory. Propulsion, steering and thruster control is configured to accept commands from the DPS.
