Enhancing The Industry’s Capability To Respond To A Subsea Well Incident

OSRL's SWIS Containment Toolkit offers an opportunity to expand on existing subsea well response capability, and enhances a subscription to the capping stack system. If well shut-in is not possible, the Toolkit can be deployed; enabling the flow of well hydrocarbons from the capping stack to an offloading tanker and is designed for use with standard industry well test hardware, to create a containment system. The Toolkit uses long-lead equipment not readily available in the industry and minimises response times by allowing a responding well operator to draw on existing resources. The first Toolkit is now available and ready to use.

To ensure a quick response, we have stored the Toolkit in strategic locations around the world . The flexible flowlines and jumpers are stored in three regional sets in Brazil, Singapore and the UK. All other components can be moved by air and will be predominantly stored at the original equipment manufacturers' facilities in Houston, Norway and the UK.

Key Facts:

  • Usable with a wide range of Mobile Offshore Drilling Units (MODUs) as capture vessels
  • Compatible with standard well test equipment
  • Stored in strategic locations around the world to facilitate a timely response
