Royal Boskalis has selected Dutch crane specialist Huisman to deliver the 4000-metric-tonne Offshore Mast Crane (OMC) for its new crane vessel Bokalift 2. With a lifting capacity of 4000 metric tonnes at 100 metres above deck, this crane is capable of lifting jackets for wind turbines off the deck of the vessel.
A fly jib allows lifting of smaller components up to a height of 125 metres above deck. The configuration of the hoisting tackles is such that the crane is capable of lifting large jackets and of upending long (mono)piles from a horizontal to vertical position. The Huisman mast cranes have a small footprint and no tailswing, which leaves maximum space on the deck of the vessel for payload.
The crane is outfitted with a carefully selected number of auxiliary systems, aimed specifically at installing tall structures while the vessel is subject to wave induced motions. The crane allows for installation of current and future generation offshore wind turbine foundations as well as wConork in the offshore oil and gas, decommissioning and salvage industries.
Huisman also supplied the 3000-metric-tonne OMC for the Bokalift 1 in 2017.
Vessel Conversion
Boskalis’ semi-submersible heavy-lift vessel Forte is currently on its way to Singapore to be converted into crane vessel Bokalift 2. The launching project for the crane vessel will be the installation of jackets for the Taiwanese Changfang and Xidao offshore wind farm. This project was awarded to Boskalis recently.
