Introduction In the deep waters off the coast of Angola, a major offshore operator faced a significant flow assurance issue with one of its 12-inch gas gathering flowlines. The suspected culprit? Hydrate plug. Hydrate formation is a major flow assurance concern for...
Smooth Sailing with ACFM Crack Assessment on Cargo Ship Propellers.
The Archon Gabriel Bulk Carrier was navigating the cold waters of the Gulf of Finland. The harsh sea conditions, laden with sea ice, posed significant navigational challenges and resulted in the ship’s 6-meter diameter bronze propeller suffering ice damage. Given the...
Diverless ACFM Inspection Solution for FPSO Bilge Keel Weld Integrity Assessment.
FPSO operators are increasingly seeking ways to inspect their hulls below the waterline without resorting to drydocking, a costly process that entails significant production loss, rendering it inefficient and logistically challenging. Recognising the benefits of a...
Tethered ILI Robotic Solution for Internal Riser and Pipeline Inspection
The Challenge bp sought a comprehensive, circumferential 360-degree scan of the riser. TSC Subsea provided the solution - a robotic system that could both travel longitudinally along the riser and had the ability to precisely stop and stabilise itself, in order to...
Innovative Approach to Subsea Pipelines Ovality Assessment with Dent Mapping and Wall Thickness Measurements.
The anchor was discovered during a pipeline jet trenching campaign using a multi-beam sonar system, producing a 3D image of the pipeline and the abandoned anchor on the ocean bed. Although the area was marked as a no-anchor zone, prohibiting vessels from...
Flooded Member Detection (FMD) of Complex Riser Caisson with Acoustic Resonance Technology (ART)
The Challenge TSC Subsea received a request from Ocean Infinity on behalf of Orsted, a Danish multinational energy company, to perform a comprehensive Flooded Member Detection (FMD) inspection on a Riser Caisson. The purpose of the caisson inspection was to ascertain...
Offshore Drilling Rig Weld Inspection with Diverless ACFM
The combination of ACFM (Alternating Current Field Measurement) technology and the MagCrawler offers a cost-effective, efficient, and reliable solution for inspecting critical welds on offshore jack-up drilling rig spudcan connections. This approach helps ensure the safety and uninterrupted operations of the client’s valuable asset.
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 subsea welds.
The Challenge TSC Subsea received a request from a major operator, Equinor AS, to evaluate the feasibility of inspecting subsea welds on risers coated with thermally sprayed aluminium (TSA). Specifically, the inspection focused on assessing the fillet weld surrounding...
Inspecting Concrete Weight Coating (CWC) 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 Pipeline Sand Erosion Inspection with 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.
