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 transportation and installation (T&I) contractor, building on Norway’s long and proud heritage in maritime pioneering. The Company is a leading company within heavy transportation, having routinely transported the world’s heaviest and largest structures since the company was founded in 2006, dominated by Oil & Gas clients.

In Q1 2021, OHT will increase the capabilities with addition of a new heavy lift crane installation vessel to the fleet, currently under construction at China Merchants Heavy Industry (CMHI) facility in Jiangsu. The innovative Alfa Lift project of Ulstein design is a response to the increasing demand for efficient transportation and installation solutions within the offshore wind market.

OHT has in October 2020 signed a shipbuilding contract with China Merchants Industry Holdings, for the construction of the first of two next-generation turbine installation vessels of GustoMSC NG-14000XL-G design. They will be designed and built specifically to install the future-generations of offshore wind turbines and XL monopiles, and will operate with significant reductions in their environmental footprints. The first unit is scheduled to be delivered in Q2 2023.

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