Vertech was privileged to manage Woodside Energy’s FPSO fleet from 2014 to 2020. During this time, we completed all statutory topside, process, plant, and structural inspections and accredited marine-class tank inspections.
Woodside FPSO Fleet Inspections
Over this seven-year term, the Vertech team introduced new technologies and methods to increase efficiency and repeatability, and they successfully executed hundreds of complex tasks and scopes with an outstanding safety and quality record.
Typical scopes of work included:
- Marine class programme management.
- Brownfield Project management.
- AICIP In-service inspection of pressure vessels & piping.
- Integrity Engineering.
- Remote Digital Visual Inspection (RDVI).
- Complex shutdown (SD) and turnaround (TAR) scopes.
- Unmanned Aerial Vehicle (UAV) Surveys.
- Advanced and conventional NDT.
- Rope access NDT, CVI & GVI.
- Comprehensive Marine Class Surveys.
- Marine Class Integrity Services.
- RTM Decommissioning.
- RTM Life extensions.

The Fleet
Okha FPSO
The Okha floating production storage and offloading (FPSO) vessel is an oil production facility moored to a riser turret located approximately 115 kilometres northwest of Dampier, Western Australia. Flexible flowlines connect the Cossack, Wanaea, Lambert and Hermes oil fields. Crude oil is offloaded from the facility via a flexible line to bulk tankers, while a pipeline exports LPG-rich gas from the Cossack and Wanaea fields to the NRC before being transferred to the Karratha Gas Plant for processing.
Ngujima-Yin (NY) FPSO
The Ngujima-Yin FPSO is an oil production facility located over the Vincent oil field in Western Australia, 50 kilometres northwest of Exmouth. Ngujima-Yin is a Thalanjyi word meaning “to dream.” The Greater Enfield Project was completed in 2018, developing the Laverda Canyon, Norton over Laverda, and Cimatti oil accumulations through a subsea tieback to Ngujima-Yin. The project scope included a major refit of the Ngujima-Yin FPSO, subsea infrastructure installation, and 12 development wells.
Nganhurra (NGA) FPSO
The Nganhurra was built in the Samsung shipyards on Geoje Island, South Korea, in 2006. Its build and commissioning took 19 months, setting an industry record for a complete FPSO project. The asset was moored at a reservoir, about 50 km north, northwest of Exmouth, on the Enfield Oil field, until the curtain fell in Q4 2018 on Nganhurra’s 13-year stint. The last three years of operation saw the asset deliver a top-quartile performance with an average reliability of more than 96 per cent.
Northern Endeavor (NE) FPSO
The Northern Endeavour Floating Production Storage and Offloading (NE FPSO) facility started production in 1999. It is located offshore in the Timor Sea, approximately 550 km West of Darwin and 250 km East-Southeast of Kupang in West Timor. In 2016, Northern Oil and Gas Australia purchased the asset and associated fields.
