Huisman was chosen by Boskalis to deliver a 4,000mt Offshore Mast Crane (OMC) to be installed on their crane vessel Bokalift 2.
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.
