Background
Since the water ingress into the insulation due to insulation damage has been found at some locations of the GBS piping and pressure vessel, the risk of the corrosion under insulation (CUI) is increased. To inspect and mitigate this CUI, the list of piping and pressure vessel that require full shutdown has been identified for inspection during the 2016 full shutdown campaign. Insulation replacement and/or paint repair may be needed depends on the severity of the damage.
CONTRACTOR is requested to perform offshore site survey to determine spare insulation materials, equipment, and manpower required to support above mentioned inspection activities during GBS full S/D 2016 (28 April – 9 May 2016, tentatively).
