Improving NDT Inspection of Welds in Subsea Sensors

Wed, 23 April, 2025

We are launching a new Joint Industry Project (JIP) dedicated to improving the full volumetric inspection of critical welds in subsea sensors used by the oil and gas industry.

API standards require that critical welds on subsea sensors used by the oil and gas industry undergo full volumetric inspection, which can cause issues for manufacturers.

These requirements currently lead many manufacturers to design larger welds than are necessary or else use substandard inspection techniques that could allow serious defects to remain in the welds during service.

The aim of this JIP is to address this issue across two phases, each of which will last 12 months. These phases will develop and qualify innovative and improved NDT techniques and procedures specifically designed to detect the types of defect that occur in the small, autogenous electron beam and laser welds that form the pressure boundary of subsea sensors.

Those who are interested in this project are invited to attend a webinar on 13 May, 2025, where our experts, Dr Ian Nicholson (Technical Consultant and Business Development Lead) and Alan Clarke (Principal Project Leader) will provide more details.
