Between 2015 and 2020, Vertech implemented its full range of conventional and advanced NDT services, marine class, in-service inspection (ISI), and robotic inspection services (RDVI) across three FPSOs, conducting over 30,000 accredited inspections. During the contract, we completed all facility statutory inspections of pressure equipment, FPSO hulls, cranes, lifting gear, and structures as part of our major services agreement with Woodside Energy.
FPSO Integrity & NDT
In-Service Inspection Services
Vertech assisted our client to manage their asset integrity by applying best practice engineering principles to develop bespoke solutions. From high-level strategies through to detailed engineering analysis, inspection planning and implementation. Our practical scope of works included inspecting the process and utility piping, including valves and fittings, pressure vessels, columns, serially produced vessels (gas cylinders, accumulators), heat exchangers and atmospheric and low-pressure storage tanks.
