Vladimir Filanovsky Offshore Field, Caspian Sea, Russia

Vladimir Filanovsky Field is located approximately 50km offshore, in the northern part of the Caspian Sea.

Discovered by Lukoil in 2005, the field began production in October 2016. The investment for the construction of the offshore field and its ancillary equipment is expected to be approximately $2.3bn. The field contains oil with 0.1% sulphur content.

The offshore field has gas and oil located within the Albian and Aptian stages, and Neocomean superstage of the early Cretaceous sediments in water depths of 10m.

The reserves of the field include 153.1 million tonnes of oil and 32.2 billion cubic metres of gas.

Vladimir Filanovsky offshore field infrastructure

The existing infrastructure at the Vladimir Filanovsky offshore field includes an ice-resistant fixed platform (IRFP-1), a living quarters module platform (LQM-1), a central processing platform (CPP) and a risers block (RB) platform, which is linked with connection bridges. The second stage of field development includes the construction of IRFP-2 and LQM-2 platforms.

"The reserves of the field include 153.1 million tonnes of oil and 32.2 billion cubic metres of gas."

The 15,200t IRFP-1 is used for drilling and operation of wells. The CPP, weighing 21,000t, is used for processing and piping ashore the oil and gas. The RB platform connects the infield pipelines with export pipelines. The LQM-1 accommodates 125 people, including a helipad.

The ice-resistant offshore platforms are connected through pipelines to the Yury Korchagin fields. Construction works include the laying of 330km of subsea pipeline and 350km of onshore pipeline.

The works also include the construction of an onshore terminal with a storage capacity of 80,000m³, located in the Republic of Kalmykia. The oil and gas from the onshore terminal will be transported to the Caspian Pipeline Consortium's pipeline.

The oil is treated using two processing lines, with each line capable of processing three million tonnes a year.

Construction of the offshore platforms

Assembling of the parts for the transport and installation barge (TIB) was used for construction of the offshore platforms commenced in December 2012. The barge measures 140.3m in length and 62.3m in width. It was delivered in mid- 2013.

"The field is located approximately 50km offshore, in the northern part of the Caspian Sea."

With a loading capacity of 13,450t, the TIB was used for pile mounting the structures of the offshore platforms, and installing the catwalk bridges between them using a 400t offshore crane.

The TIB also assisted in the installation of the topside sections for IRFP-1, CPP and LQM-1. Two additional pontoons were attached to the TIB apart from the normal two pontoons, for this purpose.

The construction of subsea pipeline system to connect the two offshore fields began in April 2012. The pipeline measures 40km in length and is equipped with band anodes, a three layer polypropylene coating and a solid concrete ballasting coating.

Contractors involved with the Caspian Sea-based project

United Shipbuilding has been contracted to supply IRFP-1. CPP was supplied by Globalstroy Engineering, while the platforms LQM-1 and RB were supplied by Krasnye Barrikady Shipyard.

Transportation and installation of the platforms and bridges was undertaken by Saipem. The company has also been contracted to lay two 114km long export pipelines from the RB to the landfall. The oil pipeline has a diameter of 22in, whereas the gas pipeline is 28in in diameter. The construction works were carried out using the barges Costoro 12 and Costoro 16.

Bumi Armada is responsible for laying nine starting sections of the subsea pipelines from the RB, measuring 90km in length. The construction was carried out using the company's barge Armada Installer, which has a gross tonnage capacity of 10,850t and is capable of laying pipes at water depths of up to 300m. The contract value is $200m.

The overall concept and design for the development of the offshore field was prepared by CNGS Group. Three platform supply vessels (PSVs) for the offshore field were supplied by Palmali Shipping Services and Agency.

Heinen & Hopman received a contract to provide HVAC equipment for IRFP-2 of the Vladimir Filanovsky Field in June 2016.
