Subsea Grout Integrity Assessment with ART
Grout integrity verification of subsea structures is now possible thanks to TSC Subsea’s innovative technology and the development of its unique solution, the ART GUIDE scanner.
Deploying dual NDT methods for the inspection of complex welds.
The Challenge TSC Subsea received a request from a major operator, Equinor AS, to evaluate the feasibility of inspecting subsea risers coated with thermally sprayed aluminium (TSA). Specifically, the inspection focused on assessing the fillet weld surrounding an anode...
Inspecting Concrete Weighed Pipes with SPECTA
The Challenge TSC Subsea was contracted by a client to carry out wall thickness assessment of Condensate Export Pipeline (CEP) and Pipeline End Manifold (PLEM) without removing the protective concrete weight coat (CWC). The assessment was required as the client...
Subsea Phased Array (SPA)
TSC Subsea were challenged to investigate sand erosion concerns on subsea structure piping off the coast of Western Australia. The inspection campaign covered multiple assets including Pipeline End Manifold (PLEM), tie in spool and subsea cooling skid in the Halyard Field and a PLEM in the East Spar Field.
Custom Designed Extrados Scanner for Inspection of Subsea Gas Lift Riser
TSC Subsea rises to the challenge of scanning and data collection on small diameter pipe bends by developing a custom designed “extrados scanner” for inspection of gas lift risers.
Multiple technologies deployed on multiple inspections across multiple assets by a single inspection vendor achieves big savings for the client.
External Subsea Inspection of Flexible Risers
TSC Subsea’s Acoustic Resonance Technology (ART) is currently the only third-party validated method of subsea detection of liquid ingress in the annulus of flexible production risers. It is deployed using the ARTEMIS® tool which has a broad application range and can be used on risers and flowlines down to 3000m water depth.
Deployed for first time by mini ROV provides a proven solution for diverless ACFM® inspection of subsea welds
ACFM® MagCrawler™ Challenge On behalf of Stinger Technology AS, TSC Subsea were contracted to carry out a subsea, remotely- deployed Alternating Current Field Measurement (ACFM®) inspection at Repsol’s YME platform YME, located in the Egersund basin area in the...
ACFM® NodeScanner™
TSC Subsea was contracted by Ocean Breeze Energy GmbH (OBE), for selected weld subsea inspections at the BARD Offshore1 wind farm in the German Bight. Commissioned during 2010-2013, the wind farm consists of 80 5MW turbines and a single Offshore Substation Platform...
Pushing the boundaries of deepwater
hydrate detection capability
The ART vPush was designed and developed by TSC Subsea’s UK team, working closely with the company’s acoustic scientists based in Norway, to meet the specific needs of the operator for this project. They required an external pipeline medium inspection, through...
4” of Coating no Match for ART – Successful Testing & Campaign for multiple flowlines, risers, & Jumpers
The purpose of the inspection was to measure effective steel thickness through 4 inches of pipeline insulations made of Glass syntactic polypropylene and injection moulded polypropylene. Scanning operations were carried out at 2000 meters water depth. More than 40...
ART® vCaliper – The Solution for Tight Access Ovality and Wall Thickness Subsea Inspection
The Challenge TSC Subsea was initially contracted by C-Innovation to conduct weld inspections for a major operator in the GOM. Within its life extension plan, the operator is required to carry out crack detection of the column to pontoon welds as part of its UWILD...
When size matters, the ARTEMIS® vCompact will get you out of a tight spot
The Challenge Beach Energy Ltd contracted TSC Subsea to carry out a wall thickness inspection through coating on the 20” Otway pipeline located near the Thylacine A platform in the Bass Strait, Australia. The inspection was to determine the size and depth of corrosion...
