“Cargo well received, and thanks again for the great job! All went very well, and appreciate the support. Good luck with the next loading, and safe voyage to you and your crew.”

Jeremy Abercrombie, Marine Operations Manager, Noble Drilling

The five OHT open deck semi-submersible heavy transportation vessels; Eagle, Falcon, Hawk, Osprey and Albatross are suitable for dry transportation of offshore drilling rigs, offshore modules and all other oversized floating and non-floating cargoes.

OHT transports:

  • Jack-up’s and semi-submersible drilling rigs
  • Liftboats
  • Cranes, jackets, barges, dredgers
  • Modules, ship sections
  • Offshore wind foundations
  • Other Floating/non-floating cargoes

OHT semi-submersible vessels cover size classes for cargoes up to 40,000 – 55,000 mt.

Prior to the project execution, careful planning is performed in order to secure a safe operation. Each cargo requires thorough study of technical details to bridge the gap between theoretical calculations and practical solutions on board. The engineers are involved in the whole project process and keep close communication with the customer, loadmaster, and ship captain.
