MWCC orders OceanWorks’ subsea dispersant fluid system

OceanWorks International delivered a Subsea Dispersant Fluid System (SDFS) to Marine Well Containment Company (MWCC).

The system will be a part of the emergency response tool kit for a well control incident in the deepwater U.S. Gulf of Mexico.

The SDFS system supports dispersant supply from the surface as well as autonomously from the seabed. To reduce vessel crowding at the intervention site, the SDFS system delivers dispersant from more than one mile away from the incident site. The system can function autonomously for up to five days without intervention.

The system utilizes a series of individual modules including twelve dispersant bladder skids (previously delivered to MWCC by OceanWorks), two gathering manifolds, three autonomous pumping stations, two intermediate manifolds, and two mixing chambers to inject dispersant at the Subsea Containment Assembly.

The SDFS System will upgrade the existing Subsea Autonomous Dispersant Injection (SADI) system currently employed by MWCC. It is a custom design based on learnings from the initial SADI and evolving understanding of the functional and operational requirements. This vision was handed to OceanWorks’ engineering team and the end result is a system that provides reliability, safety and security in deployment and operation, the company explained in the release.
