Vessels & FPSO Inspection

Ask an Expert

Survey and inspection campaigns are important inputs in the asset integrity management system (AIM) of FPSOs and other floating offshore facilities. Such units often stay on site for the duration of the field, necessitating smart, planned inspections. TSC Subsea’s experience and technologies provide an array of tried and tested solutions.

Vessels & FPSO Inspection

Vessel and FPSO inspections are vital when you have to perform class surveys or inspect for corrosion and failure sites on:

• Risers/flexible risers
• Mooring chains
• Hulls
• Propellers
• Welds
• Mid-water arches

Transforming FPSO Hull Inspections: A Cost-Effective, In-Service Solution with ORCA.

The FPSO in question is a single-hull vessel originally built in 1981 and later converted into a disconnectable FPSO in 2008. It is classed by Lloyd’s Register and has operated under a periodic inspection regime since its conversion, with a dry dock Special Survey 8...

ARTEMIS: Through-Coating Inspection for Large-Diameter Subsea Pipelines.

A primary objective was to assess areas expected to become dead legs as a result of future pipework rearrangements. These dead legs, along with the commingling point for flow back to Nyhamna, have been assessed as susceptible to Flow-Assisted Corrosion (FAC),...
