Use of Cofferdam for risers and jacket structures repair
Altrad Services has effectively combined its surface treatment expertise with proven access methods and solutions in the offshore Oil & Gas environment to deliver its Cofferdam concept, which comprises the repair and maintenance of risers and jacket structure elements, below and above sea level, in a confined and protected environment.
- The Cofferdam secures a safe and dry working environment for our operational personnel and controlled air temperature/humidity conditions to optimise the surface preparation and treatment process
- Each Cofferdam is installed by rope access and advanced rigging techniques, i.e. no need for crane support
- Our Cofferdams are optimised for the specific structure and surroundings and the collection of waste
- We perform our own engineering calculations and design of auxiliary substructures and supports that are required for each project.
