A real engineering challenge was given to Otech Marine Services when a series of impact damages was discovered to the pontoons hull structure under the waterline.
Otech Marine Services was contracted to deliver a complete turnkey repair solution with immediate start-up.
Dry-dock was for this project not an option and the design and engineering of smart habitat and cofferdam solutions was necessary in order to access and perform the works.
At the same time coordination of simultaneous operations and water integrity was of highest importance.
In total the project consisted ofreplacing more than 200 m2 of hull plating, stiffeners and structural class approved steel up to 10 meters under the waterline and took more than 15 000 engineering/manhours.
For our team in Otech Marine Services another challenge subsea was solved and we invite you to watch our video from the project.
