Subsea Testing From ROVs (UK)


TWI has successfully completed a collaborative project – SubCTest – to develop novel NDT procedures and equipment for deployment from remote operating vehicles (ROVs) on subsea offshore structures and pipelines.

The project was carried out by a consortium of small-to-medium sized enterprises, research organisations and end-users and was supported by a €1million grant from the European Commission within their Framework 7 funding scheme.

The TWI-led consortium developed a range of novel NDT techniques using phased array ultrasonics, alternating current field measurement (ACFM) and long range ultrasonic testing (LRUT). The equipment included a design of phased array transducer for multi-skip and creep wave ultrasonics, an ACFM array probe that allows scanning of complex node welded joints in a single pass, a race-track LRUT technique for chains and an orbiting focused LRUT technique for welds.

A robotic manipulator was successfully demonstrated from an observation class ROV and furthermore, simulations were used to demonstrate performance when used on an offshore ‘jacket’ structure.

6th Offshore Well Intervention Conference Gulf of Mexico

The Offshore Well Intervention Gulf of Mexico conference (OWI GOM) is returning to Houston, Texas for its sixth year on Wednesday 20 – Thursday 21 November.

Featuring Anadarko, BP, Shell, Chevron, BHGE and Oceaneering, the conference aims to help operators transition to the latest compliance updates, WI systems and business models that enhance safety, quicken well access and improve commerciality.

Across two days, more than 200 delegates, 15 exhibitors and 30 speakers will network together and create solutions to some of the most pertinent industry challenges right now, through a conference programme focused on:

  1. Clarifying compliance updates
  2. Quicker well access and safer well control
  3. ​Understanding HPHT well intervention (systems)
  4. Forecasting well intervention activity, discussing new commercial models and comparing platform options
  5. Best practice riserless well intervention
  6. ​The latest well intervention equipment
