Home Fossil Energy WATCH: Heerema’s huge vessel takes Woodside’s most current decom ‘turning point’ to recycling lawn
December 20, 2024, by Melisa Cavcic
Australian energy giant Woodside has actually made more development in decommissioning and taking apart activities at a field off the coast of Western Australia. Thanks to Heerema Marine Contractors’ heavy lift vessel, a riser turret mooring (RTM) has actually now reached the Australian Marine Complex (AMC), where it will be gotten ready for recycling and reuse chances.

Woodside is decommissioning the Griffin field, which lies roughly 65 km northwest of Onslow and 94 km northeast of Exmouth in around 130 meters of water depth. While in production, the field made up the FPSO Griffin Venture with 12 production wells, completely plugged in 2017, from the Griffin, Scindian, and Chinook tanks routed to the riser turret mooring through versatile and stiff flowlines.
While oil items were supported and kept for unloading through tanker, gas was carried to the coast through the Griffin gas export pipeline (GEP) for the domestic market. After the field stopped production in 2009, the Australian giant began putting its decommissioning strategies into action. To this end, the company handed out a batch of decommissioning offers to numerous gamers.

This allows Transocean, TechnipFMC, Heerema, McDermott, Fugro, DOF, and McMahon to take part in the elimination and disposal of subsea facilities from numerous oil and gas fields offshore Western Australia, consisting of Griffin.
The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) accepted Woodside’s environment strategy on November 21, 2023, allowing it to carry out closure of the Griffin field centers.
A couple of months later on, NOPSEMA provided Woodside’s thumbs-up to completely decommission in situ the subsea facilities at the field, consisting of approximately 11 of the 12 riser turret mooring anchors and associated anchor chains, 5 stacked structure structures, and 6 concrete gravity bases.

Woodside has actually now validated the elimination of the Griffin riser turret mooring. Heerema Marine Contractors’ Aegir heavy lift vessel transferred the RTM to the Australian Marine Complex, where it is being cleaned up and deconstructed in preparation for recycling and reuse chances.
The Griffin task provided 62 billion cubic feet of gas to power Western Australia’s homes and market, in addition to 167 million barrels of oil throughout its life time. Madeleine King, Australia’s Minister for Resources, signed up with Woodside workers to witness the arrival of the Griffin RTM at AMC Henderson.
Ragan Stonier, Woodside VP Projects Australia, explained the elimination of the RTM as a presentation of the business’s ongoing dedication to decommissioning jobs in a safe and ecologically accountable way.
“The Griffin RTM elimination is another turning point for Woodside in our decommissioning journey, which up until now has actually seen the elimination of around 25,000 tonnes of facilities consisting of more than 200 kilometres of pipeline and 100 subsea structures throughout the Enfield,
