In January 2021 Boskalis will add an existing multipurpose DP2 offshore construction vessel to its fleet. The vessel, named Boka Tiamat, will be deployed on offshore wind projects in Taiwan. It is currently being equipped with a battery pack.

The ship was ordered as Topaz Tiamat by Topaz Energy in 2015. The hull was built by Vard Tulcea SA after which it was outfitted by Vard Brattvaag, Norway. The vessel’s keel was laid in September 2016 followed by its launch on 15 December in the same year. It was delivered on 17 January 2019. Before delivery, Norwegian contractor Reach Subsea announced it would charter the vessel.

The ship is now being retrofitted with a 1300-kW SeaQ Energy Storage System, which will reduce fuel consumption and emissions during DP operations. In harbour and emergency mode, the battery pack will also have a significant impact on reducing emissions to the environment.
