Wärtsilä’s power solution to decrease need for maintenance on NUIs

Wärtsilä said that the solution could provide the asset with up to 6 months of operating time without planned maintenance activity onboard, thus enabling cost savings.

The company added that it was a power solution that could be tailored according to the requirements of each individual installation and was supplied together with a power system, including Wärtsilä dual-fuel engines, generators, and auxiliary systems.

The Wärtsilä Power Solution has been developed to allow all scheduled maintenance activities for NUIs to be performed efficiently using “walk to work” support vessels, thereby eliminating the need for on-site accommodation facilities.

Conventional offshore power solutions require monitoring and regular inspections with maintenance being carried out depending on the number of running hours of the engine.

The interval between maintenance campaigns with the Wärtsilä Power Solution requires no such activities can typically be extended by up to six months, and in the meantime, the condition of the equipment and its performance are constantly monitored and evaluated remotely.

This remote detection and diagnosis defines the actions to be taken during the next maintenance campaign, or immediately if required.

Samuli Kyttälä, senior business innovation manager of Performance Services at Wärtsilä Marine, said: “Our strategy is aimed at adding customer value by delivering energy and cost efficiency through innovative developments such as this Power Solution.

“With it, we are lowering the investment cost of the NUI and reducing its operating costs, while the Wärtsilä DF engines deliver both higher efficiency and the flexibility to change fuels. It’s a solution that simply makes sense.”
