NYK adds digital predictive maintenance for LNG carrier systems

Japan-based NYK LNG Ship Management has signed a new Guaranteed Asset Performance Agreement with Wärtsilä, which will see the vessel operator deploy digital predictive maintenance to manage shipboard systems on another of its carriers.

The deal relates to the vessel’s three Wärtsilä 50DF dual-fuel engines, as well as the Gas Valve Units (GVU) and turbochargers. Two of NYK’s sister LNG carriers are supported by similar agreements.

The contract covers the equipment onboard the LNG carrier vessel for 15 years, with the aim of maximising the ship’s uptime while providing cost predictability and optimising maintenance tasks.

Wärtsilä’s Expert Insight digital predictive maintenance system leverages artificial intelligence (AI) and diagnostics to monitor the onboard equipment and systems in real-time on shore. Should anomalous behaviour be detected, it is automatically flagged to specialists at Wärtsilä’s Expertise Centres, allowing them to provide proactive support to formulate an appropriate response.

A Dynamic Maintenance Planning system will also be provided as part of the deal, analysing equipment data to optimise major overhaul intervals without compromising reliability or engine efficiency.

“Our remote operational support capabilities represent a benchmark for the industry and allow us to provide the level of support our customers need in today’s operating environment. Agreements such as this are an integral element within Wärtsilä’s lifecycle support approach,” said Henrik Wilhelms, Director Agreement Sales at Wärtsilä.
