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

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 converted 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. The Bokalift will be used:

  • to install jackets and monopiles for offshore wind turbines
  • for the decommissioning of obsolete oil and gas platforms
  • for 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. 

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.
