Heerema’s Thialf has accomplished the eight month lengthy marketing campaign to take away the Sable Project’s offshore amenities on behalf of shopper ExxonMobil Canada.
Thialf arrived in Canada in early April and mobilized to the Sable Field on May 1 to start executing a sequence of separate lifts of platform elements utilizing a reverse-installation technique.
The Sable Offshore Energy Project concerned the manufacturing of pure fuel and condensate from 5 offshore fields positioned roughly 225 kilometres off the east coast of Nova Scotia, close to Sable Island National Park Reserve.
The Sable Offshore Energy Project produced from 5 offshore fuel fields, starting in December 1999. The fields are: Thebaud, Venture, South Venture, North Triumph, Alma and South Venture. Sable produced greater than two trillion cubic toes of pure fuel and liquids earlier than manufacturing completed on December 31, 2018. The mission supplied Nova Scotia with a brand new clear power supply and helped scale back the province’s reliance on coal and heavy gasoline oil as major power sources.
The marketing campaign entailed the Engineering, Preparation, Removal, and Disposal (EPRD) of seven platform topsides, seven jackets and 22 conductors. A complete of 5 barge hundreds carrying Sable platform elements, weighing roughly 48,000 metric tons, had been towed throughout the Atlantic by the Heerema tugs Kolga and Bylgia.
Following a mission delay because of the world pandemic in early 2020, an onboard crew of roughly 300 worldwide and home staff, aided by help vessels and helicopters, accomplished the work. The removals marketing campaign concerned a number of crew modifications and was accomplished safely and with no single case of COVID-19.
Components had been sometimes transported from the Sable Field to Chedabucto Bay to be ready (sea-fastened) earlier than their transatlantic voyage. After dismantling on the ABLE UK decommissioning yard in Hartlepool, England roughly 99 p.c of the fabric might be recycled primarily into metal.
