Offshore Production

Vertech provides a complete range of inspection, integrity management and specialist brownfield project solutions to the offshore oil and production sector. We pride ourselves on delivering high-quality, innovative solutions to even the most complex problems. Our inspections allow our clients to meet statutory obligations whilst providing valuable data to evaluate and monitor the condition of production assets as an enabler for effective and efficient maintenance planning. Our brownfield project teams include multidisciplinary, high mobility, IRATA Rope access tradesmen who provide intelligent solutions and best-in-class delivery of technically challenging projects.

Vertech is the leading service provider to the offshore production sector, as proven by long-term contracts for offshore integrity management and repeat engagements by major operators for their most complex projects. These include derrick decommissioning, flare tip replacements, Marine class special surveys, major riser and conductor IRMs, underdeck platform construction & commissioning, subsea tie-back modification projects, FPSO and fixed platform decommissioning.

Fixed Platform (FP)

A fixed platform consists of a jacket (a tall vertical section made of tubular steel members supported by piles driven into the seabed) with a deck placed on top, providing space for

crew quarters, a drilling rig if required, and production facilities. The fixed platform is viewed as economically feasible for installation in water depths up to 1,500 feet.

Floating Production System (FPS)

These are semi-submersible unit(s) which can be equipped with both drilling and production equipment. They are anchored with wire rope and chain or dynamically positioned using rotating thrusters.

Production from the subsea wells is transported to the surface through production risers. The Inpex, Ichthys Explorer, central processing facility (CPF) is the world’s largest semi-submersible production system and the first in Australian waters.

Floating Production, Storage & Offloading System (FPSO)

FPSOs are large tanker-type vessels moored to the seafloor. They are designed to process and stow production from nearby subsea wells and periodically offload to a smaller shuttle tanker. FPSOs in Australian waters connected to the seabed are under the jurisdiction of the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA).

Current operating FPSOs in Australian waters include The Okha, Ngujima-Yin, Montara Venture, Pyrenees, Ichthys Venturer, and Ningaloo Vision, with future projects including Barossa, Scarborough Browse, Buffalo (Re-Development), Sunrise, and Crux.
