Offshore (graduation) Internship Maritime Officer 

Are you ready for an offshore internship you’ll never forget on one of our crane vessels or tugs, starting this summer?

At Heerema Marine Contractors, we operate the world’s largest crane vessels and work on complex offshore projects worldwide. From installing wind turbines to removing offshore platforms and lifting structures of up to 50,000 tons. Our work is challenging, innovative, and impactful.

As an intern at Heerema, you won’t just observe. You’ll become part of the crew and gain real hands-on offshore experience. Each year, we offer nautical, technical, and combined internships on board our crane vessels and tugs. For students following the Ship Electronics (ETO) minor, we also offer dedicated technical internships. An internship at Heerema gives you valuable practical experience, professional guidance, and a strong foundation for your maritime career. It is an impressive, exciting, and unforgettable experience. We currently have internship and graduation opportunities available starting in the summer 2026 period.

Your role in the story:

During your internship, you will:

• Support daily operational activities on board

• Gain hands-on experience in offshore lifting, installation, and decommissioning projects

• Participate in nautical and/or technical tasks

• Learn from experienced Captains, Chief Engineers, and crew members

• Develop the practical skills required for your vocational or bachelor maritime education

Key ingredients for success:

You are currently enrolled in a Dutch vocational (MBO) or bachelor (HBO) Maritime Officer program and:

• You are eager to learn and open to feedback

• You take initiative and responsibility
