Greece-based ship manager Thenamaris LNG has awarded Wärtsilä an Optimised Maintenance Agreement covering the main engines for two new, ultra-modern 174,000 cbm LNG Carriers (LNGCs).
The object of the agreement is to ensure certainty of operations with budgeted maintenance costs.
The vessels, ‘Cool Discoverer’ and ‘Cool Racer’, are powered by low pressure, WinGD X-DF two-stroke, dual-fuel main engines, and were built at the Hyundai Heavy Industries (HHI) shipyard in South Korea. The five-year agreement was signed in September 2020.
Under the contract terms, Wärtsilä will enable remote support with condition monitoring systems including Expert Insight, Wärtsilä’s digital predictive maintenance product, which is now capable of supporting both two- and four-stroke engines.
To provide accurate and proactive advice and recommendations, Expert Insight utilises artificial intelligence (AI) and advanced diagnostics backed by Wärtsilä’s experience and in-house know-how. This enables prompt notification should performance deviations occur, thus allowing corrective and mitigating actions to be made early.
The solution is expected to deliver an estimated 50 per cent reduction in unplanned maintenance requirements, and an improvement of 2 to 5 per cent in fuel efficiency, with a corresponding reduction in emissions. The service is delivered through Wärtsilä Expertise Centres around the world.
“To achieve optimal operational efficiency, it is necessary to take advantage of the latest and most advanced technology. The agreement with Wärtsilä allows us to benefit from the technological and physical support they can provide through Expert Insight and their global service network. The tailored agreement addresses our main concerns and needs, and provides ways to better manage our costs and risks,” said Andreas Rapanakis, deputy technical manager, Thenamaris LNG.
“Our Optimised Maintenance Agreement is the smart way to ensure that the increasing complexity of modern engines is handled efficiently. It is an important element within Wärtsilä’s Lifecycle Solutions offering, which strengthens the business performance and competitiveness of our customers. We will be providing a broad range of services to support the reliable and efficient running of these vessels, including 24/7 remote technical support, contract management, maintenance planning, and annual engine health audits, as well as the planning and delivery of spare parts prior to each engine overhaul,” said Rajeev Janardhan, sales manager, two-stroke engine Lifecycle solutions, Wärtsilä Marine Power.
