CAIRO-- Egyptian contractor SAPESCO Offshore Services has commissioned CSL for repair/refurbishment services in the Gulf of Suez.
Last month, CSL was due to repair an oil leak in the 18-in. (45.7-cm) Younis production pipeline in 63 m (206 ft) water depth. The initial work scope involved dredging, concrete coating, and coal tar enamel removal in the area closest to the leak.
A pipeline clamp was then due to be deployed and installed by an ROV to ensure the integrity of the pipe seals. The clamp’s weight – more than 2 metric tons (2.2 tons) – necessitated substantial subsea buoyancy to enable successful positioning.
CSL also assisted SAPESCO with design, engineering, testing, and installation operations to reinforce a flare stack structure on an offshore production complex operated by an unnamed international oil company.
The complex comprises two, eight-leg steel jackets linked by a 100-m (328-ft) long flare bridge, supported by two tripods and one quadruped jacket structure. The outermost structure supporting the flare stack had undergone corrosion in its deck, legs, and splash zone bracing.
An ROV performed rectification measures in a water depth of 38 m (124 ft), using customized clamps made in the UK. After latching the clamps onto the subsea structures, grout was drilled and injected into the cavities of each of the flare stack legs – an all-in engineering approach which CSL claims is a world first.
