General arrangement
Accommodations are provided for a combination of 26 crew members and scientists in 14 staterooms located on the upper deck. The crew complement is ten for all voyages and the combination of ROV staff and scientists (16) brings the total vessel complement to 26.
Equipment and control/monitoring systems
The main machinery plant is diesel electric with a common power bus connecting five generators. Any combination of generator operation will provide power for both propulsion and other vessel operations. This design arrangement provides a high level of machinery plant redundancy and operational flexibility. Propulsion power is transmitted through two duplicate drive trains, each consisting of a DC electric motor and fixed pitch propeller. Silicon controlled rectifiers (SCR’s) are used to convert generated AC power to DC propulsive power. Two electric motor-driven bow thrusters are installed to enhance maneuvering and station-keeping.
