Diamond D was awarded this vital restoration project which consisted of the energized replacement of the 6.75 mile transmission line due to the impact of Hurricane Zeta which supplies power to Grande Isle and Port Fourchon, Louisiana’s southernmost port, which services over 90% of the Gulf of Mexico’s deepwater oil production and 16 to 19% of the U.S. oil supply. Our team safely performed the installation and removal of all access matting, stream and pipeline crossings, cattle guards, and gates as well as the installation, maintenance and removal of Stormwater Pollution Prevention Plan (SWPPP) Features. Diamond D also performed the unloading and staging of all caissons, structures and conductor, removal and disposal of all demolished structures and conductor, and restoration of all project access roads and off-site laydown areas.
The DDI team was faced with a major challenge only 26 days into this 9-month project as Category 4 Hurricane Ida made landfall, with the eye of the storm passing less than 10 miles from the project. Hurricane Ida damaged or destroyed more than 80% of the existing Golden Meadow to Clovelly Transmission line, changing the scope of work from an energized reconductor to a complete demolition and rebuild of the transmission line. Faced with major logistical challenges including the lack of daily life-necessities, our team was able to re-mobilize all temporary facilities, project equipment, and personnel. This change of scope necessitated a complete revision of the project execution plan, schedule, and pricing. DDI was able to commence work in less than 10 days after Hurricane Ida’s landfall and zero delays in the project work.
