Platforms A, B, and Hillhouse Pipeline Replacement Project

Project Details

Dos Cuadras Offshore Production Unit | Carpenteria, CA

DCOR, LLC (DCOR) replaced five subsea pipeline segments within the Dos Cuadras Offshore Production Unit, at Platforms A, B, and Hillhouse. A dynamically-positioned (DP) reeled pipelay vessel brought in from the Gulf of Mexico was used to install the pipeline segments.

This project was a replacement-in-kind and improved the safety and reliability of the subsea pipelines. Approval from the Federal Government was received in November 2011. Installation was completed in January 2012.

DPSI’s scope of work included:

  • Engineer of record for the subsea pipeline replacement project
  • Preparation of the technical submittal for permitting to the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) on behalf of DCOR
  • On-site construction management, inspection and quality assurance during installation of the subsea pipelines
