Boskalis owns and operates a large and versatile fleet consisting of construction support vessels, anchor handling tugs, oceangoing tugs and semi-submersible barges. With our experienced team, we are able to deliver multidisciplinary services worldwide to accommodate client requirements: from chartering services to fully integrated solutions for the Transport & Installation (T&I) – and the disconnection – of floating production systems.

Our services include wet transport/towage solutions, anchor and mooring installation, and the positioning and hook-up of floating production units such as FPSO, FSU, FSRU and FLNG units, semi-subs, and SPARs. We also provide solutions for the disconnection and decommissioning of these units. We offer full in-house project management and engineering services to deliver tailor-made and cost-effective solutions for our clients, drawing on our global network and strong track record with years of experience in offshore marine services.
