Deka Project From Evaluation to Start-Up

DEKA Project is a subsea gas development located in Temsah Concession about 70 km offshore Nile Delta in Egypt. The project considers the exploitation of the two fields of Denise and Karawan located in 80m – 100m water depth. Tecnomare, as engineering Company of eni, has been involved from the conceptual to the execution phase, up to start-up with a double role of "owner engineer" and "engineering contractor". Conceptual and FEED engineering has been performed between end 2011 and 1Q 2012, supporting the project approval based on 5 well subsea production system connected to an existing gas network and controlled through subsea umbilicals from a topside control system located on a new extension of the existing Seth Platform. After the project Approval For Expenditure tecnomare leaded a project management subsea team formed with EPC Contractor to follow-up the SPS (Subsea Production System) EPC Contract, interface with the flowlines and installation contractors, and support Petrobel during offshore campaign and start ups.As engineering contractor, tecnomare continued the fruitful collaboration of the Seth EPC Consortium with Local Contractors for upgrading the Seth Platform, installed in 2012, with topside control and chemical injection systems for DEKA wells, through the realization of a new-built deck extension, and a new EDG. The paper will present the project activities performed by tecnomare and will analyse the main criticalities faced during the project. The paper will also focus on potential advantages for Company of performing in-house engineering, showing that brings to schedule optimization, flexibility and prompt answers that in the contest of minor field is required to comply with time-to-market and design-to-cost drivers.
