  • The A-frame vessel interfacing on the Boka Falcon.

End of 2019, Ulstein Design & Solutions BV was awarded the engineering contract by Boskalis to support in the modification of the Boka Falcon vessel for installing a large 250 t A-frame. Ulstein was responsible for the design and strength analysis of the A-frame structural integration, developing the bolted connection and check on vessel stability.

Ulstein colleagues Jeroen Taen and Edwin van Leeuwen also performed the inclining tests of this Belgian flagged and BV classed vessel. In close and very pleasant cooperation with the Boka Falcon crew, an initial deadweight survey and inclining test was performed in May 2020 to assess the lightship weight of the vessel prior to the A-frame installed. On Friday 3 July Ulstein successfully conducted the final inclining test at the shipyard Reimerswaal.

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.
