Magnetic Particle Inspection
We conduct underwater Magnetic Particle Inspection (MPI) on offshore steel, detecting cracks to ensure weld integrity, compliance, and asset life extension for FPSOs, semi-submersibles, and floating wind platforms.
Key Benefits
Detect Surface and Near-Surface Cracks in Ferrous Materials
Reliable flaw detection in structural steel under offshore conditions.
Life Extension Without Replacement
Pinpoint defects where structural failure risk is highest.
Regulatory compliance
Meet statutory obligations under frameworks like the UK’s HSE or Norway’s Havtil.
Support life extension
Identify aging mechanisms and plan maintenance or upgrades.
Validate barriers
Confirm that structural elements remain effective as part of the safety-critical barrier system.
Supports All Asset Types
For any offshore structures including fixed platforms, FPSO’s, floating wind structures, & Semi Submersibles.
Service Description
We conduct Magnetic Particle Inspection (MPI) across a range of offshore steel structures to detect cracks and discontinuities. MPI is widely used in FPSO hulls, riser interfaces, semi-submersible braces, and wind platform weld zones, offering high reliability in flaw detection on ferrous components.
Our inspectors operate with certified equipment and follow strict protocols to ensure reproducible and class-compliant results.
Operational Scenario
Real Results: Possible Crack in FPSO Bilge Keel.
Challenge
Potential crack in FPSO bilge keel flagged during IMR ROV GVI.
Solution
SubseaPartner mobilized a dive team, & cleaned the suspect location, a close visual inspection indicated a crack, this was confirmed by underwater MPI.
Outcome
Crack was cut out therefore stopping any further development into hull material.
