The BP-led Shah Deniz consortium is on track for first gas for stage 2 of the giant project next year, following the installation of the last two major topsides facilities in the Caspian Sea, offshore Azerbaijan.

Earlier this week, the second topsides unit built for the Shah Deniz Stage 2 project, the production and risers (PR) platform, was installed. The installation of the first unit, the quarters and utilities (QU) platform topsides was completed in early-July.

The PR platform unit, weighing some 15,800-tonne and 100m long by 60m wide, contains a 133m long flare boom, 10 flowline reception facilities, five production separators, two flash gas compressors and three production export flowlines.

The transportation, floatover and installation activities took six days to complete. The unit was installed on top of the PR jacket, which was awaiting the deck in 94m water depth.

The PR platform topsides unit was completed ahead of schedule, and sailed away to the Shah Deniz contract area in the Caspian Sea from the Azfen fabrication yard in Bibi-Heybat on 15 September. Prior to that, the topsides unit was jacked up onto the loadout frame at the quayside of the fabrication yard on 6 August 20, BP confirmed.

The construction of the PR topsides unit was built by the AMEC-Tekfen-Azfen (ATA) consortium at the Azfen fabrication yard.

“We are very pleased to deliver this final offshore installation activity safely and in time to support the giant Shah Deniz Stage 2 project completion and first gas delivery next year,” Ewan Drummond, BP VP, Projects said. “I am pleased to say that the project is making good progress towards full completion on schedule and below the planned budget.”

The Shah Deniz field spans some 860sq km, and is about 70km offshore Baku, Azerbaijan, in 50-500m water. The field holds approximately 40 Tcf of natural gas in place, making it one of the world’s largest gas-condensate fields, and one of BP’s largest discoveries to date.

The project consists of Shah Deniz Stage 1, with the capacity to produce some 10 Bcm/yr of gas, and about 50,000 b/d of condensate; Shah Deniz Stage 2, which will add an additional 16 Bcm per year of gas production; and the Southern Gas Corridor pipeline system that will help deliver 6 Bcm/yr of gas to Turkey and a further 10 Bcm/yr of gas to markets in Europe.

Earlier this month, the Shah Deniz JV launched the subsea construction vessel for the giant Shah Deniz 2 project, the US$378 million Khankendi. The flagship vessel was specifically designed and built to install the biggest subsea production system in the Caspian Sea as part of the Shah Deniz Stage 2 project. 

The Shah Deniz consortium consists of: operator BP (28.8%), TPAO (19%), Petronas (15.5%), AzSD (10.0 %), Lukoil (10%), NICO (10%) and SGC Upstream (6.7%).
