Projected capacity of the first phase of the GTPP is 96 MW, with capacity to be scaled-up to a total 144 MW, making this the most significant such facility in the Yamal peninsula.
The GTPP currently under construction will provide power for production facilities at the Novoportovskoye field; for the crude oil acceptance-transfer unit in Cape Kamenny; for Vorota Arktiki (the Arctic Gate) terminal constructed by Gazprom Neft in the offshore waters of the Gulf of Ob to ensure year-round oil shipments; and for local services and engineering support facilities. The installation of three 16 MW-capacity gas turbine units was preceded by engineering works and site preparation for construction of the facility, including the installation of piling foundations and the in-situ installation of a supporting steel-frame structure.
Vadim Yakovlev, First Deputy CEO, Gazprom Neft, commented: “The Novoportovskoye field’s remoteness from key infrastructure networks necessitated the construction of our own independent generator. The use of our own energy sources — natural gas and associated petroleum gas (APG) — will allow Gazprom Neft to provide very competitively priced electricity and power for production facilities, improve the viability of developing the field, and increase the level of APG utilisation.”
The main power plant commissioned under the first phase will comprise gas turbine units of 16 MW each, designed and custom-made to order for project operator Gazpromneft Yamal and produced by domestic manufacturer OJSC Perm Engine Company, part of OJSC MC United Engine Building Corporation. Factory testing of an individual turbine was successfully completed in January 2015.
The key facilities at the plant will be two turbine halls, a gas treatment system, a boiler room, an emergency diesel electric power station, and 25 MVA transformers.
The Novoportovskoye field is one of the most significant oil and gas condensate fields currently under development in the Yamal Peninsula. It is located within the Arctic Circle, some distance from pipeline transportation infrastructure. Recoverable C1 and C2 reserves are estimated at more than 250 million tonnes of crude and condensate, as well as more than 320 billion cubic metres of gas (including Paleozoic deposits). A pilot field development programme was completed at the Novoportovskoye field in 2014, with production drilling commencing thereafter.
Shipments by sea from Cape Kammeny have been identified as the optimum solution for the transportation of crude. The first opportunity for despatching oil by sea during the winter season was confirmed by Gazprom Neft as early as 2011, following a pilot voyage by an icebreaker from the port of Sabetta (in the north—east of the Yamal peninsula) to Cape Kammeny. The characteristics of this new Yamal oil (new Novy Port crude) place it in the “light” category; with a low sulphur content of around 0.1 percent, exceeding the quality not only of Urals blend, but also Brent crude.
