Fast lift of the Tyra East Alpha topsides

Описание: Allseas’ heavy lift vessel Pioneering Spirit completed a successful processing and accommodation topsides and flare jackets removal campaign as part of the Tyra Redevelopment Project for Total E&P Denmark.

Pioneering Spirit removed more than 27,000 tonnes of platform facilities from the North Sea’s Tyra gas field, transporting the structures to specialist yards in Denmark and the Netherlands for recycling.

The final two structures, flare jackets, were from Pioneering Spirit to a cargo barge for load-in to the Sagro yard in Vlissingen, the Netherlands. The two processing and accommodation topsides and connected facilities were delivered in two earlier trips to the M.A.R.S. recycling yard in Frederikshavn, Denmark.

Structures were removed one-by-one in a time-critical sequence of lifts that required Pioneering Spirit to cover hundreds of miles between Denmark, the North Sea and the Netherlands during the two-week execution window.

Pioneering Spirit (formerly Pieter Schelte) is the largest construction vessel in the world. Inspired by the offshore heavy lifting pioneer Pieter Schelte Heerema (1908–81) and designed completely in-house, the vessel is designed for the single-lift installation and removal of large oil and gas platforms and the installation of record-weight pipelines.

The emergence of Pioneering Spirit signifies a step-change in offshore installation and decommissioning. Capable of lifting entire platform topsides of up to 48,000 t and jackets up to 20,000 t in a single piece, she significantly reduces the amount of offshore work associated with installation and decommissioning, moving the work onshore where it is safer and more cost effective.
