September load out for Snorre BProjects and Operations // July 28, 2000
Fabrication of the semi-sub started in May of last year, with hook-up of the topsides and hull scheduled to take place at Aker Stord, Norway, at the end of this year. Tow-out to the field is due to take place in May next year.
Smit Transport & Heavy Lift has been awarded the contract for the load-out and float-off of the Snorre B hull, a ring pontoon structure, which is being built at the Cadiz yard of Dragados Offshore.
The hull structure weighs around 15,000 tonnes. The ring pontoon is 85m square and is 8.5m high. It consists of four linked pontoon sections with a column at each corner. The distance from the top of the columns to the bottom of the hull is 39.8m.
Smit says the semi-submersible heavy barge Giant 4 will perform the assignment, loading out the lower hull by skidding it onto the barge, providing in-harbour towage of the loaded barge from the central quay at Dragados to a designated location in the Bay of Cadiz.
On arrival at this location, the Giant 4's main deck will be submerged, and the float-off performed. Smit says its scope of work includes detailed engineering for the load-out, in-harbour towing and float-off, and design of grillage and sea-fastenings, and the management and performance of operations at Cadiz.
Giant 4 is expected to spend some four weeks at Cadiz during the Snorre B assignment. The first three weeks will be occupied with the preparation of large skid beams on the deck of the Giant 4; the load-out and float-off will take place during the finalweek of the visit.
Smit Transport & Heavy Lift was responsible for a series of heavy lifts during the completion of the Terra Nova Floating Production, Storage and Offloading (FPSO) platform, assigning the sheerlegs Asian Hercules II to carry out 18 heavy lifts to enable the FPSO to be outfitted.
