OHT is a specialized heavy transportation and installation (T&I) contractor, building on Norway’s long and proud heritage in maritime pioneering.

A leading company within heavy transportation, OHT have routinely transported the world’s heaviest and largest structures since the company was founded in 2006. As one of the most experienced heavy transport vessel operators in the world, and a leading provider of highly engineered marine transportation solutions, they have transported well over a hundred jack-up drilling rigs for the majority of the world’s rig-owners. Handling oversized and challenging cargoes is OHT’s trademark. It is this track record and experience which underpins the company’s investment in the future generation of heavy crane vessels.

In early 2022, OHT will increase their capabilities with addition of a new build heavy lift crane vessel to their fleet - Alfa Lift. The vessel is currently under construction at China Merchants Heavy Industry (CMHI) facility in Jiangsu. OHT has also signed a shipbuilding contract with China Merchants Industry Holdings, for the construction of the first of two next-generation jack-up vessels of GustoMSC NG-14000XL-G design. The jack-ups will operate with significant reductions in their environmental footprints. The first unit is scheduled to be delivered in Q2 2023.

OHT serves clients from a wide range of industries including oil & gas, offshore wind and marine infrastructure, providing experienced inhouse engineering and strong project expertise. OHT’s transport and heavy lift fleet are ideally suited for use on decommissioning projects.

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