Wartsila has secured a contract to provide power generation and propulsion packages for three vessels being built for Singapore-based offshore service firm Pacific Radiance.
According to Pacific Radiance, the new power systems will help the vessels achieve better fuel consumption, greater efficiency and lower emission levels.
Of the three vessels, two are 86m platform supply vessels (PSV) being built at Huang Pu shipyard in China and the third, being built at China’s Zhenjiang shipyard, is an anchor handling tug supply (AHTS) vessel equipped with a hybrid diesel-mechanic and diesel-electric propulsion system.
Wartsila will deliver all the equipment during 2013 with the ships scheduled for delivery to Pacific Radiance during the first half of 2014.
Under the deal, the company will deliver four 6-cylinder Wartsila 26 in-line main engines, thrusters, and the electrical and automation systems for the two PSVs.
Additionally, the AHTS will receive two 6-cylinder Wartsila 32 in-line main engines, two generating sets, two controllable pitch propellers, thrusters, and the electrical and automation systems.
Wärtsilä Low Loss Concept (LLC) power distribution system for electric propulsion applications will also be supplied to the PSVs.
These will be the first vessels built in China to install the LLC system.
Pacific Radiance chief operating officer BH Lau said the Wartsila LLC system includes high redundancy, high efficiency and fuel economy for the entire electric propulsion application.
"The design of the 690V switchboard and power distribution system gives less single failure consequences and more available power, better operability, and safety during the vessels’ dynamically positioned (DP) mode," Lau said.
Vice president of Wartsila Ship Power, Offshore Magnus Miemois said the company’s Wartsila hybrid propulsion system is designed to minimise the total installed power and to create efficient propulsion across the entire operating profile of the vessel.
"The hybrid solution results in fuel cost savings and reduced levels of exhaust emissions, both of which are key market requirements," Miemois said.
"The fully integrated power generation and propulsion systems ensure optimal performance, while having a single point of contact for the entire systems not only reduces the completion risks, but notably enhances efficiency throughout these complex projects."
