Safer, Together

We invest in people.

At DM Group Services, safety isn’t a buzzword; it is the cornerstone of everything we do.

Our investment in people is a direct consequence of our commitment to safety. Not just people who work with us, but people in our industry as a whole. It is one reason why we run IRATA certified rope access training courses. Or  why we are pursuing development of advanced ROVs that will take divers out of the water.

We are in for the long haul.

Operational since 1974, we have won the trust of our clients – nearly 90% of our business today comes from our longstanding client relationships. We have spent and we will continue to spend years in the maritime industry, working to achieve the trust of our clients.

Call it the orientation of a family run business or a passion for the industry we are in.
