Bisso Pulls 700 Tons on 200 Ton Jackets

Thursday, August 18, 2005
Bisso Marine was contracted to remove four structures in the Eugene Island area. The 105 ft., 200T jacket structures were designed, built and installed in 1958, each of which had a complete mud mat floor with a five foot retaining mud wall. The original installation of the jackets to the required depth below natural bottom required the use of a jetting system which was built into the jackets. Fast-forward 47 years, Bisso Marine mobilized the D/B Boaz to location and removed the 75T deck sections from each structure and then prepared the structures with explosives to severe the jacket from the piles. The 700T capacity D/B Cappy Bisso was then rigged to each jacket and maintained a constant strain in order to break the mud suction. The D/B Cappy Bisso held a strain on each to the four jackets for a few hours; the break out forces ranged between 580T and 700T per jacket. Once the D/B Cappy Bisso had the mud mat above the natural bottom, the rigging was transferred to the D/B Boaz, which then lifted the jackets on to the material barge.
