๐ Tender Overview
Scope of Work:
Sakarya FEED and EPCI Project - Second Phase.
Sakarya Field Location Details
The Sakarya field is located in the western part of the Black Sea, around 165km offshore from Filyos, in Zonguldak province.
The Sakarya project includes a subsea gas production system in the gas field; a gas receiving and processing terminal in Filyos Industrial Zone in the รaycuma district of Zonguldak province; a pipeline to transport gas from the field to the terminal; another pipeline for mono-ethylene glycol (MEG) transportation from the Filyos facility to the field; and an umbilical, all including shore crossings.
In Phase II, the field will be connected to the subsea production system with up to 30 additional wells. This will increase the number of wells to 40, including ten from Phase I.
The second phase will also involve the installation of a 24-inch or above pipeline to transport the additional gas produced by the offshore field.
The onshore production facility will process the gas, following which the gas produced will be measured at a Fiscal Metering Station (FMS) and transported to the national grid through a 36km onshore pipeline.
The FMS and the pipeline will be operated by Petroleum Pipeline Corporation (BOTAล).
