You will tackle challenges which have never been done before and optimize our ways of working by creating sustainable value in finding solutions for re-using equipment and materials. 

You will have the opportunity to go offshore on our vessels and see your designs and work in action, supporting our fleet with anything that requires a bright technical mind and pro-active attitude. You have a learning mindset. You are open to feedback, curious and eager to learn. You are enterprising at heart, have a pioneer’s spirit and take control of your own work and development.

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.
