Under the five-year agreement, the team will provide condition based maintenance and dynamic maintenance planning for eight new offshore supply and multi-purpose support vessels including six LNG fuelled platform supply vessels and two offshore construction vessels powered by diesel fuel.

The agreement ensures ideal running conditions of 18 Wärtsilä 34 dual-fuel engines and eight Wärtsilä 32 engines in optimal level as well as optimized maintenance for Harvey Gulf’s new vessels.

Additionally, the deal includes online remote operational support to allow Wärtsilä’s technical experts to support vessels in real time.

Harvey Gulf CEO Shane Guidry said: "And 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."

Wärtsilä North America service director Walter Reggente said: "With this extended partnership, we will enable the safe and reliable operation of their offshore supply and multi-purpose support vessels throughout their lifecycle."
