Wärtsilä has been awarded a five year optimised maintenance agreement covering the main engines for two new 174,000 cu m LNGCs managed by Greek-based Thenamaris LNG.
The vessels, ‘Cool Discoverer’ and ‘Cool Racer’, are powered by low pressure, WinGD X-DF 2-stroke, dual-fuel main engines, and were built by Hyundai Heavy Industries (HHI) in South Korea. The agreement was signed in September, 2020.
Under the contract terms, Wärtsilä will conduct remote support with condition monitoring systems, including Expert Insight, Wärtsilä’s digital predictive maintenance tool, which is capable of supporting both 2- and 4-stroke engines.
To provide accurate and pro-active advice and recommendations, Expert Insight uses artificial intelligence (AI) and diagnostics backed by Wärtsilä’s experience and in-house knowhow.
This allows 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% reduction in unplanned maintenance requirements, and an improvement of 2 to 5% in fuel efficiency, with a corresponding reduction in emissions. This 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,” added Rajeev Janardhan, Sales Manager, 2-stroke engine lifecycle solutions, Wärtsilä Marine Power.
Thenamaris LNG currently manages eight vessels with an additional five newbuildings due for delivery by 2022. Wärtsilä has an existing ongoing technical management agreement with the company covering the Wärtsilä engines in three LNGCs fitted with diesel-electric technology.
Wärtsilä currently has about 700 vessels under maintenance agreements, of which around 160 are LNGCs.
Through Wärtsilä’s and WinGD’s 10-year service partnership agreement signed in December, 2017, Wärtsilä has access to WinGD’s Intellectual Property Rights (IPRs) and technical specifications and is an authorised global service provider for all WinGD engines.
