Boskalis operates one of the largest fleets of specialized offshore vessels in the world. We serve a variety of projects - from ocean transport of a drilling rig, to the subsea installation of an offshore production platform or an offshore wind farm. Our fleet is regarded as one of the most versatile, able to meet the variety of different requirements that may be demanded by each project.

Our fleet includes heavy lift vessels, cable-laying vessels, heavy transport vessels, multipurpose / cable-laying vessels, fall pipe vessels, semi-submersible heavy lift vessels, diving support vessels, offshore construction support vessels, anchor handling tugs, floating sheerleg cranes and survey vessels.

Furthermore we have specialized mission equipment such as trenching equipment such as ploughs, jetting and mechanical trenchers, subsea pre-piling frames, ROVs and various innovative subsea cable tools to support and enhance our activities in the offshore energy industry.

Semi-submersible heavy transport vessels

Specialized marine vessels used in a number of specific offshore transport roles.

Heavy lift vessels

Cost-effective and flexible solutions for heavy lift projects, most with their own means of propulsion.

Cable-laying and multipurpose vessels

Our fleet of cable-laying vessels is a truly multipurpose fleet. Besides a dedicated cable-laying vessel we own two multipurpose cable-laying vessels that are capable of cable-laying as well as executing a wide range of associated activities such as diving support, subsea rock installation, offshore construction support, salvage assignments and even dredging operations. As an addition to these vessels we own three cable lay barges to support IRM and cable joints operations. In offshore and near shore operation.

Diving support vessels

We have diving support vessels in its fleet or on long term charter. These are DP-2 and DP-3 state-of-the-art DSV’s, fully equipped with AIR diving, single and/or twin bell saturation diving and ROV support capabilities. The vessels are operated by a dedicated and experienced crew, operating 24/7 on a year around basis.

Semi-submersible oceangoing barges

We have a fleet of three dedicated semi-submersible oceangoing barges which are capable of transporting heavy or oversized offshore structures under tow. Besides transportation of heavy structures and/or floaters for offshore floating wind farms, these vessels are excellent positioned to perform float-over operations for Topside installation.

Floating sheerleg or crane barges

Floating sheerleg cranes offer cost-effective and flexible solutions for heavy lift projects. Boskalis owns a fleet of floating sheerleg cranes with lifting capacities ranging from 400 to 5,000-ton. These sheerlegs primarily carry out specialist heavy lift activities on projects, requiring specialist in-house engineering skills. Most of our floating sheerleg cranes have their own means of propulsion.

Ocean towage tugs

Our advanced ocean towage tugs are capable of towing the largest and most valuable objects afloat, such as floating production units , storage and offloading units (FPSO’s), semi-submersible drilling rigs and caissons.

Anchor handling tugs

We own a large number of smaller and larger anchor handling tugs with a capacity which ranges from 65 to 200+ tons bollard pull with ASD and/or DP2 capabilities and equipped with cargo handling systems.

Construction support vessels

Boskalis has five state-of-the-art CSV’s in its fleet or on long term charter that are known for their wide range of capabilities in the offshore construction market.

Fallpipe vessels

Our fleet of fallpipe vessels consists of two dedicated self-propelled DP-2 vessels equipped with a flexible fallpipe which can be lowered into the water. Uniquely, the fallpipe vessel can position rock with extreme accuracy down to a depth of 1,500 meters.

Various offshore vessels and equipment

Our fleet of offshore equipment includes ploughs, jetting and mechanical trenchers, subsea pre-piling frames, ROVs and various innovative subsea cable tools.
