Float-over Installation at the Vladimir Filanovsky Field

The transportation of the topside section of a central processing platform (CPP) site at the Vladimir Filanovsky field, its installation site, began this week on June 25. This transport, surveyed by Russian Maritime Register of Shipping (RS) launched at the Globalstroy-Engineering (GSE) assembly site in Ilyinka, Astrakhan region.

The CPP topside section is part of the infrastructure at the Vladimir Filanovsky field, located in the Russian sector of the Caspian Sea on Severniy license zone territory. The installation site of the CPP section is 170 km south of Astrakhan and 20 km east of Maliy Zhemchuzhny Island.

The CPP topside section consists of a metal support for the installation of process modules, designed to provide additional sustainability for oil separation equipment, gas and brine, oil offloading, and the drying and compression of gas. The technical plans were approved by the RS Head Office. The RS Astrakhan Branch Office reviewed the technical documentation for the project and provided survey during construction.

Topside section design particulars:
Depth – 38.5 m
•width – 46.7 m
•length – 74.3 m
•weight (for transportation) – 10.250 t

The CPP topside section is being transported on the Yury Kuvykin transport-assembly barge. The T-shaped barge consists of two main and two supplementary floating pontoons. The supplementary pontoons (outriggers), located in the aft section of the barge, provide enhanced stability during the transportation of  heavy freight. The Yury Kuvykin operates under the Russian flag with an RS class notation: KE✪ R2-RSN pontoon.

Barge main particulars:
•length of main pontoon – 140.00 m
•width of main pontoon – 30.00 m
•width with outriggers – 62.00 m
•depth – 7.30 m
•deadweight – about 14,000 t

The complex is being towed by one main tug, two stern-side steadying tugs and one auxiliary tug.

The CPP topside section will be installed on previously mounted supports using the float-over method.
