PPE installs O-rings for subsea operations


Precision Polymer Engineering (PPE) has installed its Perlast® G75LT and G90LT O-rings in a patented pressure-balanced disconnect system for subsea operations.

PPE’s perfluoroelastomer seals have been exhaustively tested to ensure high performance in the low temperature, high pressure environments associated with deep water drilling and production.

SECC Oil and Gas, located in the UK, specialises in connection and disconnection solutions across the sector with special emphasis on subsea applications. Its emergency breakaway system has been developed as a failsafe measure to ensure that oceanic pipelines do not rupture when extraction vessels drift from their location above the well.

Many active service vessels involved in deep water oil and gas extraction are equipped with Dynamic Positioning (DP) to maintain a fixed location when connected to the pipeline. The system monitors GPS, wind and motion sensors and adjusts the angle and output for each of the ship’s thrusters ensuring that the pipeline connection is not put under strain.
