Abstract

The subsea resident remotely-operated vehicle (SRROV) idea was published on ip.com in 2011, and enables the ability to perform several tasks beneath the ice in an offshore arctic subsea development. In locations where surface access is not an option for part or most of the year, if the primary communication link via the subsea control system fails, there will be downtime and lost production. If an SRROV is included in the subsea development, there is an option to use its communication links to provide an interim communications solution, avoiding downtime until a surface intervention can take place. The SRROV idea as published has features that could be extended for this service. The envisioned capability of the SRROV to provide alternative communication paths for the SCMs to communicate with the topsides could improve the overall reliability and availability of the subsea controls system.

Novel Idea

This extension of the SRROV technology could be integrated into the control system to provide an additional means of controlling subsea equipment, should there be an issue or failure with the primary communication system. For a point-to-point fiber optic production controls architecture, each subsea control module (SCM) will be directly wired to the topsides or onshore facility. The SRROV system will also have its own communication path directly linked to the topsides or shore, via hardwire and tether, wireless, or other communication means.

For example, if...
