what do you do with an old oil platform?
2 min read | may 06, 2022
Imagine the to-do list if you had to remove an oil platform. From the ocean.
Multiply that by five and throw in tasks to decommission two nearby gas plants and miles of pipe, and you’ll have some idea of the monumental work lined up in Chevron’s West Coast Decommissioning (WCD) Program.
what we’re doing
We’ve been checking off tasks on those to-do lists since 2018, leading a team of functional experts and partners in the first-ever decommissioning project in U.S. federal waters off the coast of California. The work is divided into four phases, with some happening at record-breaking depths. In September 2021, we moved into Phase 3 and expect to complete work before the close of the decade, depending on approval of permits.
about those permits
The federal Bureau of Safety and Environmental Enforcement, in partnership with the Bureau of Ocean Energy Management, coordinates with other federal and state agencies to review and approve the complex, carefully planned decommissioning work that we and our partners propose.
the scope
The WCD Program involves two projects, the Santa Clara Unit and the Point Arguello Unit.
- The Santa Clara Unit includes removal of platforms Grace and Gail, pipelines and an onshore gas plant in Carpinteria, south of Santa Barbara.
- The Point Arguello Unit includes removal of platforms Harvest, Hidalgo and Hermosa, pipelines and an onshore gas plant in Gaviota, north of Santa Barbara.

the short story
What exactly does it take to remove an offshore oil platform? That question can yield an answer of epic proportions, but here’s the short story in five very-high-level steps: well abandonment, pipeline abandonment, topsides removal, jacket removal and, lastly, transportation, processing and recycling. Here’s an illustration that might help, but remember, in the WCD Program there are gas plants and pipelines to isolate, clean, inspect and dismantle:
