WINDEA JULES VERNE quayside at Ulstein Verft.

Batteries for offshore wind vessel

In cooperation with shipowner Bernhard Schulte, Ulstein Design & Solutions has designed a diesel-electric propulsion system assisted by batteries to reduce operating hours on the main engines, save fuel and reduce environmental footprint. The hybrid system has been installed on the WINDEA JULES VERNE at Ulstein Verft.

Ulstein Design & Solutions AS is responsible for the system architecture of the power package and energy management system, while Blue CTRL delivers ULSTEIN IAS?, the integrated automation system.

By installing a battery system in addition to the regular generator sets, one will be able to achieve a more even load on the generators, called peak shaving. Short-term increases of the load are handled by the battery system rather than by the generators and a comparative reduction of load will lead to a recharge of the battery system. A more even load on the generators is achieved, and energy is thus saved.

In addition, the battery system will function as a backup. This means that DP operations can be carried out with only one generator set in operation. This is fuel efficient and saves maintenance and operating hours.

The requirement for DP operations is a functionable ship even if the systems in half of the vessel fail.

Using batteries as backup will reduce the operating hours of the main engines as only one engine is in operation and not two. The on-board control systems will ensure that the power produced by the generator sets will match the power requirements, as well as ensuring that the energy stored in the batteries will be sufficient for the ship's operations.

Inclining test completed on Orient Adventurer - Aftermarket services that keep vessels fit for new roles

Vessel conversions and re‑mobilisations demand more than drawings and calculations. Recent work on Orient Adventurer, now being prepared for cable-laying operations, demonstrates how critical in-depth knowledge of a vessel’s operational history is to deliver safe, class-approved solutions. Through Ulstein’s aftermarket services, we support complex vessel upgrades with engineering, stability, and weight expertise, including planning and executing inclining tests for conversion and life‑extension projects.

How Ulstein tested a new cable-laying vessel design

How can you be confident that a new vessel design will actually perform in rough seas and demanding operations? The answer lies in thorough verification, independent testing and documented performance. Recently, a new Ulstein design for a cable-laying vessel was tested in a large-scale ocean basin at SINTEF Ocean. The results delivered exactly what Ulstein seeks: confidence that the design performs as intended.
