Scaldis Decommissions Offshore Platform in Three Days
In April 2016 Tullow Oil awarded Scaldis with the contract to remove the offshore Horne & Wren platform and the company immediately started the extensive preparations and engineering works.
The plugging & abandonment (P&A) of wells and offshore preparatory works were carried out from the jack-up vessel Kraken. While Simultaneous Operations (SIMOPS) of the P&A took place, Scaldis also performed Non-Destructive Testing (NDT) of the topside pad eyes, installed an access platform between the jacket and topside and placed a gangway landing platform on the jacket.
Rambiz was mobilised from Vlissingen, the Netherlands, on 10 March 2017 and arrived at the offshore field two days later. Over the following three days, the complete platform was decommissioned; an in- and out-seabed survey was carried out; the topside was cut, lifted and sea fastened onboard the Rambiz; the jacket piles were dredged and cut; the Internal Lifting Tools (ILT’s) were installed; and the jacket was lifted. The Rambiz returned to a disposal yard in Vlissingen with the topside stowed on deck and the jacket suspended in the PS crane.
