Working at Heerema Marine Contractors

Heerema Marine Contractors has built itself a solid global reputation in the offshore industry. Originally for the transportation and installation of fixed oil and gas platforms, standing on the seabed. And for the removal of old platforms at the end of their working life. We are helping the industry to push back its own boundaries. By enabling it to operate further and further from the coast, for example, and in ever deeper water. Heerema owns the largest crane vessels in the world: Sleipnir, Thialf, Balder and Aegir. In addition, the Heerema fleet has a range of equipment, such as tugs, barges, offshore lifting and pile-driving equipment.  

Opening up opportunities at these extremes, where conditions are often very difficult, has required an exponential increase in the scale and complexity of the necessary infrastructure. This means that you will face new and even greater challenges, demanding your ingenious solutions and contractor mentality.
