The five-year agreement was signed in August 2014 and applies to eight new offshore supply and multi-purpose support vessels – six liquefied natural gas (LNG) fuelled platform supply vessels and two offshore construction vessels powered by diesel fuel.

Wärtsilä says that the agreement will mean that Harvey Gulf can enjoy ideal running conditions and optimised maintenance for its new vessels, ensuring that their engines – 18 Wärtsilä 34 dual-fuel engines and eight Wärtsilä 32 engines – always run with optimised fuel economy and maintenance costs.

The technical management aspect of the deal is based on continuous condition monitoring data and periodical inspections.

The agreement also includes Online Remote Operational Support, which enables Wärtsilä's technical experts to support vessels in real time, without the need for engineers to travel to the vessels.

"We are extending our partnership with Wärtsilä, through this technical management agreement, to assure our new fleet of vessels are maintained to the highest standards of safety, reliability and availability," said Shane J. Guidry, CEO of Harvey Gulf.

The Condition Based Maintenance system optimises maintenance intervals by feeding engine parameters into Wärtsilä's database to be evaluated by specialists at the Condition Based Monitoring centre.

Wärtsilä says that this enables early detection of performance issues, reduced downtime, as well as optimised engine performance and fuel consumption.

Knowing the actual condition of the engine also allows for the implementation of the Dynamic Maintenance Planning concept, to reduce operating costs by optimising the timing of major overhauls and reducing the consumption of spare parts.
