Offshore orders for high speed Cat engines
Caterpillar has picked up some significant offshore orders for its 3500 series diesel electric engine
Caterpillar Marine Power Systems has won two significant orders for its 3500 series diesel electric propulsion engines to power offshore support vessels.
Four Cat 3516C generator sets will be installed onboard a SV-310 multi-purpose offshore construction and supply vessel for US operator Harvey Gulf International. Each genset will provide 2,250kWe at 1,800rpm, and will include CleanAIR after-treatment solutions, enabling the vessel to qualify as US EPA Tier 4 compliant in addition to meeting the EPA Tier 3 and IMO II regulations.
The 3516C features electronic fuel injection and Adem A4 electronic control units to optimise power supply, fuel consumption and exhaust emissions at any given load. The 92m SV–310 MPSV is being constructed by Eastern shipyard for New Orleans-based Harvey Gulf, which provides environmentally-friendly OSVs in the deepwater Gulf of Mexico.
Caterpillar is also supplying over 100 3500 series gensets to the Sinopacific shipyard in China, to provide diesel electric propulsion systems for 20 AHTS and 20 PSVs being constructed for the French Bourbon Offshore. 60 Cat 3516C engines will be packaged with Kato generators for the AHTS vessels – three sets per ship – while each PSV will be powered by a diesel electric plant based on four 3512C gensets.
Rated power is 2,000kWe at 1,800rpm for the 3516C engines, and 1,360kWe at 1,800rpm for the 3512Cs. As with the Harvey Gulf order, the engines for Bourbon will feature electronic unit injection and Adem A3 control units. The Bourbon engines are IMO Tier II and EPA 2 compliant.
