The tank had suffered from corrosion under insulation (CUI) to the vertical tank shell.
The 24” line buried 10 metres below the ground, had suffered from external corrosion which led to a through wall defect.
The 3 x 24” lines had suffered from excessive external corrosion at the bottom of the lines which are exiting the concrete floor.
The heat exchanger was subjected to thermal cycling that caused a crack to appear at the edge of the expansion joint
The 20” line had suffered from CUI external corrosion on the pipe coming off the vessel.
The 24” line had suffered from severe internal erosion resulting in a through-wall slot defect at a lap joint flange.
The 18” water injection riser clamp joint had suffered from movement inside the retaining clamp when operating at high pressure.
A long section of this line is suffering from multiple external corrosion scabs resulting in a minimum remaining wall thickness of approximately 14-18mm.
The 24” line had suffered from external corrosion. This resulted in several through wall defects along the butt weld near the flange
During normal operating conditions a seawater leak was identified on the seawater supply line.
The 4”x6” GRP Tee had suffered from a crack resulting in a through wall pin hole leak.
The 2” line detailed above has suffered from a series of cracks and though wall defects resulting in various leaks through out the full line
The 8” line had suffered from internal corrosion/erosion. This resulted in a through wall leaking defect close to the valve flange assembly at the 4 o’clock position
The 6” Tee with 4” branch had suffered from external corrosion close to the Tee.
The 20” line had suffered from internal erosion. This resulted in through wall defects on the flange.
The 8” steam header had suffered from internal erosion causing a through wall defect.
The water tank had suffered from possible internal acid corrosion.
The 30” Crude oil line had suffered from (CUI) external corrosion.
The 48” Cooling Water line had suffered from external and internal corrosion.
The ½” hydrocarbon gasoline line has suffered from internal, external corrosion.
The 4” Condensate line had suffered from coating damage resulting in a localised corrosion area.
The cooling water line had suffered from severe external corrosion.
The 8” Produced water line had several leaks from an internally corroded weld.
The Fuel oil storage tank had suffered from external corrosion resulting in a through wall defect behind a large corrosion scab.
A cracked leaking weld had appeared on a 2” drain line and valve assembly due to vibration in the line.
Deck plate surface beneath the crane headache ball 'parking' box was suffering from corrosion, resulting in localised corrosion and through wall leaks.
The roof/deck plate had suffered from heavy corrosion over a 15 metre squared section.
An emergency situation occurred where the bottom slip on flange of the fire water system started leaking.
A hairline crack was identified on a 24" GRE Seawater line at the flange, resulting in a leak.
The cooling water return line has been repaired using welded patches during a recent shut down.
The 24” Raw Water line was found to be suffering from severe external corrosion
The cooling water line had a number of leaks and required a live repair.
The 1.5” offtake had developed a number of pin hole leaks from the weld
