On 17 May, a steel cutting ceremony took place at the shipyard Drydocks World in Dubai for the Bokalift 2 conversion project. The new crane vessel for Royal Boskalis Westminster N.V. (Boskalis) is being prepared for foundation transportation and installation work in the Changfang and Xidao offshore wind farm project in Taiwan.
This milestone marks the beginning of an important new phase in the modification of the vessel’s hull and deck. The conversion scope includes the fabrication and installation of 9,000 tons of steel blocks on both sides of the vessel to increase the stability of the vessel and the installation of a new work deck.
Boskalis is using an existing hull for the Bokalift 2. It has previously also done so with the Bokalift 1. The DP2 vessel, with accomodation for 150 persons, has a free deckspace of 7,500 m2. A 4,000 ton crane will be installed on the vessel in 2021. This revolving crane, to be supplied by Huisman, will be capable of lifting structures more than 100 meters high.

The wind farm is a project by Copenhagen Infrastructure Partners (CIP) and two Taiwanese life insurance companies.
