LNG Carriers managed by Greece-based Thenamaris LNG Inc. 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 shipyard in South Korea. The five-year agreement was signed in September 2020.
The object of the agreement is to ensure certainty of operations with budgeted maintenance costs. Under the contract terms, Wärtsilä will enable remote support with condition monitoring systems including Expert Insight, Wärtsilä’s unique digital predictive maintenance product, which is now capable of supporting both two- and four-stroke engines. To provide accurate and pro-active advice and recommendations, Expert Insight utilises artificial intelligence and advanced diagnostics backed by Wärtsilä’s vast 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 percent reduction in unplanned maintenance requirements, and an improvement of 2 to 5 percent in fuel efficiency, with a corresponding reduction in emissions. The service is delivered through Wärtsilä Expertise Centres around the world.
Thenamaris LNG Inc is a global ship manager of high specification, modern ocean-going vessels, and currently manages eight vessels with an additional five newbuildings set for delivery by 2022. Wärtsilä has an existing ongoing Technical Management Agreement with the company covering the Wärtsilä engines in three LNG vessels fitted with diesel-electric technology. This however is the first Maintenance Agreement signed with Thenamaris LNG Inc. for two-stroke engines.
