In June 1997, it took 144,000 BHP to get the Hibernia Gravity Base Structure transported from the "Bull Arm"-building facility at Newfoundland in Canada to its present offshore location.
The displacement platform was over 600,000 ton and 224 meters in height. Because of its impressive measurements, it was taken in tow by a huge fleet of 11 Maersk Supply Service support vessels that were specially designed to tow in harsh environments - as on the banks of Newfoundland. The platform should be accurately positioned and firmly placed on the seabed within very sharp tolerances.
The contract between HMDC and Maersk Supply Service for the transport was concluded almost 1 year prior to the scheduled date. This was just enough time to get the project organized and to plan the mobilization of the vessels.
The 11 towing vessels were taken in from The North Sea, Africa, Mediterranean, Far East and Brazil. It was a puzzle to have the vessels arriving at Newfoundland at the exact date and time as stipulated in the contract.
The towing of the Hibernia Platform was coordinated by 2 experienced tow masters from Maersk Contractors. So the overall operation was in the full hands of Maersk Supply Service, and it was performed on schedule without accidents and with a positioning well within the tolerances.
