DECOMMISSIONING & ABANDONMENT
LT preservation fluid is in a class by itself. This proprietary fluid provides superior corrosion protection for metallic components while being very friendly to elastomers and other non-metallic materials. The fluid is oil based, so it provides excellent water separation and high dielectric properties while being naturally long lasting to protect subsea equipment components. Since the fluid is derived from natural oils, it is nontoxic to aquatic life, biodegradable, and extremely safe for personnel.
Defender Stasis LT is the first non-aqueous subsea equipment preservation fluid that meets regulatory requirements for direct discharge to sea from subsea oil and gas facilities in U.S. offshore waters. The fluid is rated as an Environmentally Acceptable Lubricant (EAL) and a Total Loss Lubricant, and easily complies with the regulations of tightly regulated markets such as Norway, the U.K. and Australia.
“For subsea trees, corrosion and calcareous deposits over the 10 to 25-year operating life of the tree will affect reliability of crown plugs, swab valves and internal tree caps, in addition to BOP connector locking and sealing performance,” remarked Thomas. “For the tree application, USI’s subsea isolation cap and preservation fluid will provide significant cost savings and risk reduction for each intervention, with real potential to extend tree operating life and well production life by several years for some wells.”

New Firm Petrodec Carrying out UK
Decommissioning Work for Perenco Perenco has confirmed it is an investor in Netherlands- headquartered Petrodec, although the firm is not a dedicated subsidiary.
decommissioning projects in its experience on its website – the Pickerill field in the Southern North Sea and conversion of the Endeavour platform, both owned by Perenco.
Petrodec, which was incorporated in the UK in July, lists two
Stephane Barc, who has spent the last nine years with Perenco, latterly focussed on decommissioning, is General Manager of the company.
Petrodec describes itself as a “perfect mix between oil and gas operator and offshore contractor background,” with ambition to “become a leader in offshore and decommissioning support.”
The scope of work it is carrying out on Pickerill
and the Endeavour is not clear.
Perenco submitted a partial decommissioning programme for the normally unmanned Pickerill A and B platforms earlier this year, which includes plugging and abandonment of the subsea wells.
Petrodec states it is working to make Pickerill “hydrocarbon- free” between 2019 and 2020.
The Oil and Gas Authority website states the hydrocarbon-free phase of Pickerill B was completed in the second quarter of this year.
Meanwhile, Perenco bought the 36-year-old Energy Endeavour jack-up rig in January last year from Northern Offshore.
