MAJOR EQUIPMENT |
PRIME MOVERS
3 – Caterpillar model 3516C Main Diesel Generator Set; turbo-charged and after cooled engines, each rated at 1,900 mechanical kilowatts at 1,800 rpm. Each engine is fitted with a 1,550 ekW, 690 VAC generator. Engines are fitted with local fresh water/salt water heat exchangers mounted on the engine skid.
1 – Caterpillar model C18 Emergency Diesel Generator Set with a 340 ekW, 480 VAC generator.
BOW THRUSTERS
2 – Variable pitch azimuth bow thrusters each driven by an individual variable speed diesel engine. The thrust is adjusted by controlling both engine speed and propeller pitch. The input power to each thruster shall be approximately 2,300 kW at 800 rpm. The entire thruster system shall be suitable for DPS-3 operation.
STERN STEERABLE THRUSTERS
2 – Variable pitch azimuth stern thrusters each driven by an individual variable speed diesel engine. The thrust is adjusted by controlling both engine speed and propeller pitch. The input power to each thruster shall be approximately 2,300 kW at 800rpm. The entire thruster system shall be suitable for DPS-3 operation.
CRANES
1 – Main Crane Huisman, Type 600 MT WTIC with the following basic specification: main hoist capacity of SWL 600t at 25 m in elevated position, minimum radius 12.3 m, maximum radius approx. 85 m; auxiliary hoist capacity of approx. 30 t, 95 m radius (2 falls), 12.1 t, 95 m radius (1 fall).
1 – Auxiliary Crane Liebherr CBW 10/25 with the following basic specification: hoisting capacity 1 0t at 3 m to 25 m radius. Auxiliary crane will be suitable for man riding (1.2 t SWL from the vessel to another vessel at Hs=2m).
JACKING SYSTEM
Electrically powered NOV/BLM rack and pinion jacking system composed of 48 jacking units. Each jacking unit powers 2 load-sharing elevating pinions arranged in sets – 3 high at each side of the chords of each of the four legs. Each jacking unit is driven by a two-speed electric motor.
