The Shell Perdido Challenge
Federal was asked to provide the majority of the pipe fittings and flanges for the Perdido Host tie-in to the Silver Tip, Great White and Tobago fields. This included requirements in a range of materials suitable for the unforgiving environment in which these components would be placed in service.
The fitting’s materials of construction comprised a microalloyed steel of SY of 70 ksi, and a martensitic stainless steel alloy in both ANSI and API geometries to meet the client’s specifications. A truncated list of the items provided in this undertaking include bulkhead anchors, pressure transmitter tees, flow tees, reducing tees, block elbows, riser hang off collars and swivel flanges. In addition, we sourced a wide range of ANSI/API flanges in sizes from a nominal 6–in. to 16–in. with varying wall thicknesses for the various flow lines and sleds. Design conditions varied from Class 1500 ANSI to 10K API over the sizes and materials aforementioned.
Our responsibilities included detailed design, materials procurement, heat treatment, quality control and manufacture and post fabrication inspection. Over the course of the project there were several required amendments significantly affecting item quantities with an overall order magnitude totaling some 780 ft of forged pipe and 240 assorted components. Even with these requirement modifications the project was successfully completed without a corresponding shift in schedule thanks to the close communication and partnership between the Federal and Shell teams.
Dedicated professionals assure all project expectations are achieved.
