Job Description

Are you ready for an offshore internship you'll never forget on one of our crane vessels or tugs, starting this January/February?

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 January/February 2027.

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
• You are social, flexible, and motivated

From whom will you learn

During your internship, you will be guided by experienced and qualified colleagues. You will work closely with our professional and highly skilled Engineers, who will support you in your development and help you build your technical and operational expertise.

As several activities overlap with the electrical department, close collaboration between both teams is essential, giving you valuable insight into multidisciplinary offshore operations.
