PTX oil offshore protected transfer

Quick and safe active shut-off coupling and release system for SPM, STS, FPSO, FSO and CBM crude oil transfer operations


The PTX Protected Transfer System enables active transfer system emergency disconnection in an emergency.

PTX is a new standard in minimizing risk to operations, assets, people, reputations and the environment: designed to meet the expectations of modern and efficient offshore transfer operations.

Transfer protection whatever the situation

PTX delivers on-deck (Active) manual control and is designed to complement the automated
(Passive) benefits of Gall Thomson MBCs.

PTX and Gall Thomson MBCs each offer different protection and transfer system control options to manage varying emergency scenarios.


Safe distance release with PTX Reflex Hydraulic Power Unit (R-HPU)

The R-HPU is a compact, pre-charged, low maintenance HPU; offering a safe and rapid hydraulic signal to the PTX Release Coupling.

The HPU is operated via pneumatic or electrical push button controls, with mechanical interlocks to prevent accidental activations.
