Shell expects to use the vessel for subsea inspection, maintenance, and repair (IMR) projects, and hardware installations. IMR projects are anticipated to include a range of intervention tasks, including chemical well stimulation and hydrate remediation. Hardware installations are anticipated to include flowline jumpers, umbilicals, production trees, and flying leads.
Under separate installation and IMR frame agreements,Oceaneering may also provide project management, engineering, fabrication, and vessel equipment and service packages to Shell on an as-needed basis to support the Ocean Alliance.
