It’s only natural that a lot of people see us as divers. Frog began business in 1969 as a diving company, and it’s very much due to our diving expertise that we have built up such a good reputation.

Diving will always be part of our core business and we also provide competence and resources within marine construction and supply. This includes towing, salvage, diving inspections (in-water surveys), hull and propeller cleaning, dredging and environmental consulting services.

With a sufficient range of equipment for ships, diving boats, barges, flat top barges, rafts, diggers and cranes, Frog Marine Service can, with our experienced staff, offer any kind of marine construction and shipping services. Our ambition is to be available anytime of the year, 24 hours a day.
