Dutch offshore wind equipment specialist Huisman has been selcted by Royal Boskalis Westminster to deliver a 4,000mt Offshore Mast Crane (OMC) to be installed on their crane vessel Bokalift 2.
"This commitment reinstates Boskalis’ confidence in Huisman as mission equipment supplier after successful delivery of the 3,000mt Offshore Mast Crane for the Bokalift 1 in 2017," said the worldwide specialist in renewable offshore wind and geothermal energy, oil and gas.
With a lifting capacity of 4,000mt at 100m 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 125m 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 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 launching project for the crane vessel will be the installation of jackets for the Taiwanese Changfang and Xidao offshore wind farm. project which was awarded to Boskalis recently.
The particular characteristics of the Huisman mastcrane have proven to be advantageous for offshore construction vessels. These cranes have a small footprint and no tail-swing, which leaves maximum space on the deck of the vessel for payload.
With its ability to lift structures more than 100 meters high Huisman’s Offshore Mast Crane will make the Bokalift 2 a flexible value adding asset, well positioned for the installation of current and future generation offshore wind turbine foundations. Also, it is well-positioned for work in the offshore oil and gas, decommissioning and salvage industries.
