Heerema Marine Contractors
Heerema Marine Contractors (HMC) is a contractor headquartered in the Netherlands most notable for operation of three of the largest crane vessels in the offshore industry.

In the 1960s the company focused on the North Sea offshore developments. The company developed crane vessels to lift large offshore platforms and modules.

The need for large stable crane vessels to operate in the North Sea environment lead the company to develop the first large semi-submersible crane vessels. In 1978, HMC commissioned Mitsui to construct the two sister semi-submersible crane vessels, and Hermod (ship), SSCV ''Hermod''. These vessels could lift 5,400 tonnes with the twin cranes, and were later upgraded to 8,200 tonnes. In 1988 HMC formed a joint venture with McDermott ...
