AHT support

Boskalis operates a versatile fleet of 70 – 205 tons bollard pull anchor handling tugs (AHTs) and offshore support vessels to assist with a variety of offshore and inshore operations, such as tug and barge towage services, station keeping and mooring installation, and oceangoing transport services.

Walk-to-work facilities

With the Ampelmann system installed on the offshore support vessel Smit Nicobar, Boskalis provides fully motion-compensated ship-to-ship personnel transfers. This system enables both accommodation and walk-to-work support for extended FPSO maintenance campaigns. The system is capable of compensating sea states in excess of 4 meters significant wave height. This ensures safe, efficient and reliable transfers of offshore personnel to fixed and floating facilities.

Heavy lift support

Boskalis operates a versatile fleet of self-propelled sheerlegs, with a lifting capacity of between 800 and 5,000 tons, to assist with a variety of heavy lifting operations, such as module integration for floating offshore production structures, installation of infrastructure in ports, and the removal of obsolete oil platforms and ship wrecks.

Logistics support

With our versatile fleet of barges and pontoons we provide transport services for heavy and non-standard cargos. Our seagoing and river barges are often customized for the requirements of specific projects. Additional equipment, including ro-ro loading systems, is available to ensure an exact fit with the specific demands of a project.

Our fleet includes pontoons (ballastable and/or submersible), floating super pallets (based on the 'piggy back' technique), barges for transporting e.g. fuel storage tanks, timber and wreck parts, and offshore installation barges. Propulsion is provided by our pusher tugs and AHTs.
