Gaslog to use AI-powered maintenance to optimise engine performance

Greek shipowner and operator Gaslog has signed a new Optimised Maintenance Agreement with Wärtsilä to cover ten of the company’s very large LNG Carrier vessels, incorporating digital predictive maintenance powered by artificial intelligence.

The agreement covers the vessels’ twin two-stroke dual-fuel main engines, which will link with asset diagnostic services including Wärtsilä’s Expert Insight system and remote operational support.

The Expert Insight digital predictive maintenance service utilises artificial intelligence (AI) and diagnostics to provide advice and recommendations to optimise engine operations. The system is able to recognise performance deviations, should they occur, allowing for corrective and mitigating actions to be taken at an early stage, thereby increasing uptime and lowering emission levels.

Wärtsilä says that the technology is estimated to reduce unplanned maintenance by as much as 50%, and to deliver an up to 5% improvement in fuel efficiency, with a corresponding reduction in emissions.

“To achieve optimal operational efficiency, we need to take advantage of the latest and most advanced technology,” said Kostas Karathanos, General Manager, Innovation & Technology at Gaslog.

“Wärtsilä’s Optimised Maintenance Agreement provides this. We have worked closely with the Wärtsilä team to create a customised agreement that addresses our main concerns and needs while providing an efficient means for us to manage both costs and risks.”
