About us

“Excellent work! Please on pass a big thank you to the crew. It is always a pleasure working with the OHT Team and knowing you are in good hands.”

Wayne Allen, Director, Marine Operations, Shelf Drilling

OHT is a specialized heavy transport and installation contractor, building on Norway’s long and proud heritage in maritime pioneering. Since the company was founded in 2006, we have successfully executed complex projects on behalf of our customers. We serve clients from a wide range of industries including oil & gas, offshore wind and marine infrastructure.

Handling oversized and challenging cargoes is our trademark, and we are proud of having transported well over a hundred jack-up drilling rigs for the majority of rig-owners in the world.

In Q1 2021, OHT will increase the capabilities and become a full transport & installation (T&I) contractor with addition of a new heavy lift crane installation vessel to our fleet. The innovative Alfa Lift project is a response to the increasing demand for efficient transportation and installation solutions within the offshore wind market.

The company’s headquarters are located in Oslo, with satellite offices in Singapore, Dubai, Shanghai and Houston.
