Wartsila machinery for Pacific Radiance newbuildsEquipment & Technology // July 5, 2012
Wartsila is to supply complete and fully integrated power generation and propulsion packages for three vessels being built for Pacific Radiance Ltd, the Singapore-based company specialising in offshore service activities.
In each case, the company's main requirements were to achieve greater efficiency, better fuel consumption, and lower emission levels. The orders were received during the second quarter of 2012.
Two 86m PSVs are to be built at the Huang Pu shipyard in China, while the Zhenjiang shipyard, also in China, will build a hybrid anchor handler vessel with more than 210 tonnes of bollard pull.
The Wartsila equipment for all three ships is scheduled for delivery during 2013, and the vessels are due to be delivered to Pacific Radiance during the first half of 2014.
Wartsila's scope of supply includes four 6-cylinder Wartsila 26 in-line main engines, thrusters, and the electrical and automation systems for the two PSVs, and two 6-cylinder Wartsila 32 in-line main engines, two generating sets based on 6-cylinder Wartsila 32 in-line engines, two controllable pitch propellers, thrusters, and the electrical and automation systems for the AHTS.
The PSVs will utilise the Wartsila Low Loss Concept (LLC) power distribution system for electric propulsion applications. These will be the first vessels built in China to install the LLC system.
A notable feature of the AHTS is that it is a hybrid vessel, combining both diesel-mechanic and diesel-electric propulsion.
"The Wartsila hybrid propulsion system is designed to minimise the total installed power and to create efficient propulsion throughout the entire operating profile of the vessel," said Magnus Miemois, Vice President, Wartsila Ship Power, Offshore. "The hybrid solution results in fuel cost savings and reduced levels of exhaust emissions, both of which are key market requirements."
