Diesel Fuel System
Total capacity: Approx. 9,900 gallons (US) in 5 tanks. Fill locations are on the port and starboard aft Main Deck house sides. Fill/transfer system includes centrifuge, pumps, meter and distribution manifold. Diesel engines draw from the day tank.
Engines and Generators are fueled via priming pumps and filters. Fuel is transferred to and from the day tank via fuel transfer pumps. Fuel is also transferred by virtue of the work of the centrifuge. Tank levels are monitored by electronic sensor, with high/low level alarms, and displayed on a vessel monitoring system display. Fuel tanks ventilate thru a “vent tank” which is monitored for overflow from tanks. Tanks are welded aluminum.

Fire Sprinkler System
The interior is protected by sprinklers that draw from the ship‘s fresh water supply. In the event the water supply is depleted, and without interruption, the system reverts to seawater use. The Engine Room is protected by a gas smothering FM200 system.
- Sprinkler system: The system is pre-charged and automatic. Water delivery is by two pumps; operating individually or in tandem. A small pressure tank maintains the stand-by pressure in the system. Control panels are located in the Engine Room and a mimic display in the Pilothouse.
Engine Room Fire System
Activated manually, the FM 200 Fire protection system is designed by Alexander Gow for Engine Room protection. Activation (with 34 second delay and alarm) includes discharge of gas (hepta-fluoro propane) and automatic shutdown of fuel pumps, intake fans, and exhaust dampers. The Engine Room and ventilation ducts are insulated against thermal conductivity.

Sound Suppression
Noise and vibration reduction concept developed by Westport Shipyard and J&A Enterprises.
- Engine Room: Noise isolation and vibration reduction techniques are used in the mounting of machinery, plumbing and wiring. Sound barriers and Soundown ® insulation further reduce noise levels.
- Staterooms and Interior: Noise transmission in the stateroom areas is inhibited via “sound tight” construction techniques, acoustic fill in double wall bulkheads, floating joinery connections in critical areas, and isolation mounting of equipment and plumbing.
