The Semco Maritime story

Semco Maritime has grown from a small company providing straight forward technical installations into a high-tech, international organisation covering all disciplines within engineering and contracting for the energy sector. During our exciting journey, we’ve held onto the can-do attitude and dedication to quality and reliability that has earned us a solid, loyal and ever-expanding customer base.

Small beginnings, great future

Our story began in 1888, when Semler & Mathiassen, a castings and stove manufacturer opened for business. But it wasn’t until 1945 that we began producing high-quality technical installations for the marine and shipbuilding industry.

We established our first offshore business unit in Esbjerg in 1980, to provide project engineering, maintenance and manpower services for the North Sea’s offshore operations. Alongside organic growth, acquisitions in Denmark, Norway and the UK have given Semco Maritime the capacity to handle even the grandest upgrade projects.

We now also have sales and marketing offices in UAE, Singapore, Vietnam, Australia, the US and Central America. And with advanced facilities in Denmark and Vietnam, we are setting new standards in the global market. Today, we’re a single-source supplier with people dedicated to exceeding customer expectations in projects, solutions and manpower for the energy sector all over the world.
