EPCI work to commence on Egypt's Phase XI Deepwater Project

The engineering, procurement, installation and commissioning work for Phase XI Deepwater Project of the West Delta Deep Marine (WDDM) concession has been vested on Petroleum Marine Services (PMS) by independent engineering consultancy Longitude Engineering

Longitude’s engineering scope comprises the detailed design of deep-water rigid jumpers, development of fabrication drawings, onshore and offshore handling procedures, offshore installation engineering, process and stress modelling, and key HSE studies and engineering workshops.

The Phase XI development of the Burullus gas field involves the tie-in of three subsea twin deep-water natural gas wells. The scope of work includes engineering, procurement, fabrication, installation, and commissioning support five subsea M-shape rigid jumpers, equipped with deep-water specialised connectors, multiphase gas meters, and sand detection systems.

Compact twin-well configurations will be installed, each with a subsea jumper span limited to approximately 25 meters in length. This will be placed in a brownfield environment adjacent to an existing live natural gas deep-water system, part of one of the largest deep-water natural gas networks globally.

A tie-in structure, namely “Tie-In Spool Base, TSB” designed to accommodate multiple jumpers within a single subsea module will offer enhanced production flexibility and enabling well allocation interchangeability.

Subsea control system components to support well operation and chemical injection. 

Located approximately 90 kilometres offshore Egypt, in the north-western Nile Delta region of the Mediterranean Sea, the WDDM concession is operated by Shell through its joint venture, Burullus Gas Company. The area includes 17 gas fields at water depths ranging from 300 to 1,200 meters.

“We are delighted to secure this contract following the success of our previous work on Phase X. The West Delta Deep Marine development is of major significance to Egypt’s oil and gas sector, and we remain committed to delivering the highest quality of service to PMS and, ultimately, to the operator,” said Daniel McGowan, Offshore Project Director at Longitude Engineering.
