Spudcan Repairs

Blu Subsea were contracted by Lamprell to conduct Spudcan repairs on ADM336 Jack up Rig. Initial inspection found 3 circumferential weld cracks; one on each spud can. Blu Subsea then came up with a method to install a cofferdam on each of the spud cans to conduct the welds in the 'dry'. After measuring of the top of the spudcan and the rig leg well, three cofferdams were fabricated. Upon sealing of the cofferdam on the spud can, the cofferdam was pumped dry ready for internal welding. Welding was conducted to complete the spud can repairs, and the cofferdams were subsequently removed.
