PCS PROJECT SCOPE: The Hurricane Repair Projects consisted of the following project scopes: Hot tap installations; Interconnecting piping installations; Pipe lay; Repair clamps; Riser repairs; Platform structural repairs; Platform pig trap repairs; Reburial of exposed pipelines; In place pipeline abandonments; Pigging procedures; Pipeline retrieval.

MO BLOCK 822 #6 PIPELINE PROJECT

OVERALL PROJECT SCOPE: The MO Block 822 #6 Pipeline Project involved ExxonMobil's first cooler-less, sour wellhead facility in the Mobile Bay area. A total of three pipelines were associated with the project, including a production flowline and two utility pipelines that extended between a minimal wellhead facility in Mobile Bay Block 822 to a production facility in Mobile Area Block 823.

PCS PROJECT SCOPE: The design included pipeline routing, pipe sizing, thermal expansion analysis, upheaval buckling analysis, riser and riser clamp design, and expansion box design for the 6-inch production flowline and two utility pipelines. PCS also designed a subsea strain gauge monitoring system in Mobile Bay, including spreadsheet software to process strain data, and provided data interpretation and reporting services. PCS provided offshore construction specialists and inspectors to help coordinate and monitor the construction work during pipeline and riser installation.

NORTHEAST GATEWAY

OVERALL PROJECT SCOPE: Offshore in Massachusetts Bay; Excelerate Energy and Energy Bridge Technology; Connects to AGT 30-inch Hubline Project Consulting, Inc. AGT facilities-16 miles of new 24-inch pipeline; Excelerate facilities-two shore 16-inch flowlines, two PLEMs, two risers and umbilicals

PCS SCOPE OF WORK: PCS is construction manager for AGT and Excelerate.

VIOSCA KNOLL GATHERING SYSTEM
OVERALL PROJECT SCOPE: The Viosca Knoll Gathering System (VKGS) consists of 94 miles of 20-inch pipe from Main Pass Block 252 to South Pass Block 55 and six miles of 16-inch pipe from Viosca Knoll Block 817 to Main Pass Block 289.

PCS SCOPE OF WORK: PCS prepared detailed cost estimates; Completed pipeline design, including, but not limited to, riser and subsea tie-ins, pipeline crossings, pipeline span analysis and design; Handled all regulatory permitting and notifications; Coordinated and managed site hazard surveys and pipeline route surveys; Provided on-site inspection services during hazard and pipeline route survey work; Identified, specified and requisitioned materials, including pipe, coatings, valves, equipment and provided vendor surveillance; Provided design and construction management of platform piping; Acted as liaison with third party contractors; Coordinated and managed site hazard surveys and pipeline route surveys; Assisted in detailed evaluation of all installation contractor bids and equipment; Reviewed and approved contractor installation procedures, third party subcontractors and welding procedures; Developed all AFC drawings; Executed on-site project management and inspection.

WEST AFRICAN GAS PIPELINE PROJECT

OVERALL PROJECT SCOPE: This project consisted of the development of an onshore/offshore gas distribution network delivering gas from Nigeria to commercial customers in the neighboring countries of Benin, Togo, and Ghana. This project included the installation of a 57km of 30-inch onshore pipeline, an onshore compression station in Nigeria, construction of a 579km offshore pipeline distribution system, and installation of individual regulating and metering stations at each of the four gas receiving points in Cotonou (Benin), Lome (Togo), Tema (Ghana), and Takoradi (Ghana).

PCS SCOPE OF WORK: PCS provided front-end engineering design and drafting services related to the offshore portion of the project. This included all pipelines, subsea tie-ins, and shore crossings.
