Cross Inlet Pipeline Project

The Cross Inlet Pipeline project is an oil and gas pipeline system that transports crude oil via pipeline rather than overwater transportation resulting in a safer, more cost-effective transport solution. Coffman provided civil, structural, mechanical, electrical, corrosion control, project management, and procurement services for the project. The project consisted of 28 miles of new crude oil and natural gas pipelines including two subsea and three onshore pipeline segments.

An existing 22 mile subsea pipeline was also converted from natural gas to crude oil service. New facilities were designed, and existing facilities modified at eight oil facilities, four gas facilities, and one offshore platform. Coffman led the project from preliminary project scoping and total installed cost (TIC) estimating, through detailed design engineering, and project scheduling and sequencing. Through the design phase, our team worked together with the Owner to value engineer the project to meet their needs. Our team created requests for proposals (RFPs) for bidding the project, led the procurement of long lead materials, and provided construction administration to project completion. Getting the project completed on an aggressive schedule, while also optimizing construction costs and meeting regulatory requirements, was a key to the project’s success.
