Floating sheerlegs and crane vessels offer cost-effective and flexible solutions for heavy lift projects. Sheerlegs are frequent visitors to ports, shipyards, offshore construction facilities and major civil projects. Self-propelled crane vessels are able to perform heavy lift works offshore.

Sheerlegs primarily carry out specialist heavy lift activities around the world on projects, requiring specialist in-house engineering skills. Most of the floating sheerlegs have their own means of propulsion.

Boskalis' floating sheerlegs have lifting capacities ranging from 400 to 5,000 tons.

Bokalift 1 crane vessel

In 2017 Boskalis will convert one of its semi-submersible heavy lift vessels into a self-propelled crane vessel, including a 3,000 ton revolving crane. The available deck space of 165m x 43m is unique in its sort and can be used to install jackets and monopiles for offshore wind turbines, the decommissioning of obsolete oil and gas platforms and transport and installation of new-build oil and gas production platforms. Due to its DP-2 capabilities there is no loss time for anchor spread deployment. The vessel can accommodate 150 persons and will have a helicopter deck available for offshore transfers. Delivery is expected at the beginning of 2018. 

 A sister vessel is also scheduled for conversion into a 3,000 ton crane vessel.

Giant 7

In 2016 the Giant 7 has been converted into a construction vessel with a 600 ton revolving crane and accommodation for 73 persons.
