Engine manufacturer Wartsila will keep maintaining the propulsion systems of much of the Angelicoussis Group’s LNG fleet until at least 2027.

Maran Gas Maritime, the group’s gas carrier arm, agreed on 3 May to extend an existing agreement with the Finland-based technology company for five years.

The deal covers Maran’s fleet of 21 tri-fuel diesel-electric LNG carriers.

The two companies first struck a five-year service agreement in 2014. It covered six vessels on 50DF dual-fuel engines, as TradeWinds reported at the time.

The Maran Gas deal was part of a network of maintenance agreements that Wartsila had signed with several Greek LNG carrier owners then, including Dynagas, TMS Cardiff Gas and Thenamaris LNG.

Wartsila has expanded that concept since, to what it describes as “Wartsila Lifecycle Agreements”.

More than 700 vessels worldwide are supported by Wartsila under such schemes, with 90% of problem cases being resolved remotely.

“We are pleased ... to renew this service for a further five years,” Maran Gas chief executive and president Maria Angelicoussis said on Wednesday.

Wartsila’s support network “demonstrates a high level of professionalism, which is important to both us and to our charterers”, she added.

The service is said to ensure early detection of performance issues, reduced downtime, optimised engine performance, predictable cash flow and optimisation of major overhauls.

Wartsila and Maran said in a joint statement that the agreement reaffirms their commitment to accelerate maritime decarbonisation.
