Fpso To Platform – Offshore Oil & Gas
Inspecting a pipeline from a platform to an FPSO is particularly challenging when passing through the flexible riser and turret into the receiver. This 2.7km 6” line carries condensate and there were concerns about wax build up as this was the first time that the line had been inspected.

Overview
Inspecting a pipeline from a platform to an FPSO is particularly challenging when passing through the flexible riser and turret into the receiver. This 2.7km 6” line carries condensate and there were concerns about wax build up as this was the first time that the line had been inspected.
A specialized compact and light weight, twin bodied tool was developed for easy launching and receiving in the restricted access space available. Gel pigs were run as the first step to provide confidence that the lines were not obstructed by wax build up.
Close cooperation between marine, operations and Dexon were required when the FPSO turret needed to be perfectly aligned with the riser to allow for the pipeline cleaning and inspection tools to pass through. Data was successfully acquired after an obstruction and incident free online run.
