Heerema Marine Contractors (HMC) is a world leading marine contractor in the international offshore oil and gas industry. HMC excels at transporting, installing and removing offshore facilities. These include fixed and floating structures, subsea pipelines and infrastructures in shallow waters, deep and ultra deep waters.

HMC manages the entire supply chain of offshore construction, from design through to completion. Headquartered in Leiden, our services encompass engineering, planning, logistics, project management and execution of projects all over the world.

HMC owns three of the world’s largest crane vessels: semi-submersible crane vessel (SSCV) Thialf, deep-water construction vessel (DCV) Balder (which is a crane vessel that also has deep-water construction capabilities), and SSCV Hermod, after years of excellent service, recently went on her last trip.

Next to the crane vessels, HMC also owns one deep-water construction vessel: the Aegir. The Aegir is a monohull vessel with the capability to execute complex deepwater infrastructure and pipeline projects in ultra deep water.

HMC is also currently developing a new vessel: the new-generation semi-submersible crane vessel Sleipnir, which is scheduled for delivery in 2018. . It will be equipped with two cranes of 10,000 metric tonnes lifting capacity each and a reinforced deck area of 220 meters in length and 102 meters in width, which will make it the largest crane vessel in the world.

The dual cranes provide for heavy lifting capacity both to install and remove jackets and topsides. Furthermore, the cranes can be utilized for installation of foundations, moorings and structures in deep water. The Sleipnir is self-propelled with a minimum service speed of 10 knots, with power generated by means of dual fuel engines – MGO & LNG. Station-keeping is by means of dynamic positioning (DP3) or mooring system.

Our fleet has large deck areas and unique capacities in the areas of heavy lifting and motion behavior. This has earned us a reputation for superior workability and excellent station-keeping. Harsh environments and great water depths demand an innovative approach, experience, and, of course, the right equipment. Our versatile fleet and sound project management ensure a smooth marine operation.
