Respected leaders in hydrographic personnel

Our story

DOHS was founded in 1989, at a time when the offshore surveying industry was increasing the use contract staff. Our founder, Dave Oliver, who was well connected in the oil industry, began receiving enquiries about suitable contractors for specific projects. He realised that offshore firms would appreciate a service partner who could take away the headache of finding qualified contractors, and DOHS was born.

Today, we have established ourselves as respected leaders in hydrographic personnel. We have a team of five in-house experts at our offices in Great Yarmouth, and a database of over 6000 contractors and industry contacts.

DOHS is a member of the International Marine Contractors Association (IMCA), the trade association representing offshore, marine and underwater engineering firms and FPAL the approved supplier database to the Oil and Gas industry.
