Wärtsilä has been awarded an optimised maintenance agreement covering the main engines for two dual-fuel LNG carriers (LNGCs) managed by Greece-based Thenamaris LNG Inc.
The 174,000 cubic metre (cbm) 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.
Wärtsilä will enable remote support with condition monitoring systems including Expert Insight, its digital predictive maintenance product which is now capable of supporting both two- and four-stroke engines.
Expert Insight uses artificial intelligence (AI) and advanced diagnostics to enable prompt notification should performance deviations occur. According to Wärtsilä, the solution is expected to deliver an estimated 50% reduction in unplanned maintenance requirements, and an improvement of 2% to 5% in fuel efficiency, with a corresponding reduction in emissions.
Andreas Rapanakis, Deputy Technical Manager with Thenamaris LNG, commented: ‘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.’
Rajeev Janardhan, Sales Manager, 2-stroke engine Lifecycle solutions, Wärtsilä Marine Power, added: ‘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.’
Wärtsilä currently has about 700 vessels under maintenance agreements, of which approximately 160 are LNGCs.
