Finland’s Wartsila and Singapore-based NYK Shipmanagement have entered a long-term optimised maintenance agreement for a liquefied natural gas (LNG) carrier.

The LNG carrier is equipped with three Wartsila 50DF dual-fuel engines and will be covered for 13 years by the agreement.

Signed in November 2021, the contract is intended to ensure equipment reliability, provide maximum uptime and reduce maintenance expenses.

Besides the maintenance and planning support from Wartsila, NYK Shipmanagement will also receive Expert Insight.

This tool supports maintenance planning on the basis of data as well as overseeing equipment and systems through the use of artificial intelligence (AI) and real-time advanced diagnostics.

Real-time monitoring enables specialists at Wartsila Expertise Centres to offer support to their clients.

By delivering advice and suggestions for fixing potential operational troubles, Wartsila will help increase the ship’s uptime and availability.

Wartsila Marine Power agreement sales director Henrik Wilhelms said: “Our lifecycle customer support approach, as emphasised by these agreements, is a value-adding benefit that works to lower operating costs, reduce fuel consumption and support the customer in their decarbonisation journey. We have enjoyed a long and close relationship with NYK group, and this agreement further strengthens the cooperation between our companies.”

In a separate development, AP Moller-Maersk has declared options with Hyundai Heavy Industries (HHI) to construct four extra 16,000 twenty-foot equivalent unit (TEU) dual-fuelled ships that will run on carbon neutral methanol.

HHI’s shipbuilding holding company Korea Shipbuilding & Offshore Engineering revealed in a regulatory filing that the deal has been valued at around $700m (KRW840bn).

Last August, AP Moller-Maersk signed an agreement with HHI for eight large ocean-going container vessels that would operate on carbon-neutral methanol. The first of these vessels will be introduced in Q1 2024.
