3X Engineering’s client seals leakages on a 14 inch pipe on a FPSO, Austral Africa
Overview
The objective of the repairs, performed early October 2023 by
3X ENGINEERING (3X)
client was to seal online 2 leakages on a 14" pipe transporting produced water located on FPSO. The leakages were due to internal corrosion. The pipeline had a pressure of 7 bars and an operating temperature of 45°C
To carry out these emergency repairs, the client decided to use a 3X emergency leak sealing system STOPKiT® Offshore that he had in stock. The client was previously trained to install this product.
Scope of Work
The pipe concerned was leaking in 2 locations. One leakage was situated on the elbow and the second leakage on a straight part of the pipe near the T.
The repairs were performed according to 3X
installation procedure described below using STOPKiT® OFFSHORE (specially dedicated to this environment) and referenced STOF114 (==> suitable reference for a 14" pipe in offshore area with a
maximum size defect of 50mm and up to 50 bars of pressure and 150°C).
- STOPKiT® were firstly positioned next to the leakages using specific positioner device.
- STOPKiT® were then slid to perfectly center the rubber patches over the defects.
- Once positioned over the leakages, STOPKiT® right and left screws were tightened until leaks were sealed (40 Nm max).
- Finally, STOPKiT® positioner devices were removed.
Both leakages were totally controlled and sealed. STOPKiT® product is as efficient on straight line as specific geometry like elbows. To guarantee the effectiveness of the product it must be implemented by trained and certified applicators.
Results
The repairs were successfully managed by the trained client and the leakages were stopped within few minutes thanks to 3X’s patented emergency leak sealing system STOPKiT®. This product is easy to store and ready to use.
