Patent ID: 7958938

Claim:
A system for supporting multiple-well-site, offshore, hydrocarbon-bearing fields, each well-site having one or more wells, the system comprising: a floating vessel that is relocatable from a position at a first well-site to a position at a second well-site; an operations control system selectively connectible to the floating vessel for providing well-site operations at the first and second well-sites, the operations control system comprising communications for at least one of commands sent to well-site equipment, and data received from sensors in well-site equipment, the operations control system comprising a control module at the first well-site; a control module at the second well-site; an inter well-site control network connecting the control module at the first well-site to the control module at the second well site; a detachable surface vessel control link configured to selectively connect with the control module at the first well-site or the control module at a second well-site so that control operations may be conducted for both the first well-site and the second well-site from either well-site; and an intervention system onboard the floating vessel for conducting intervention services to an individual well, the intervention services comprising at least one of workover services and maintenance services, and the intervention system being configured to provide intervention services to an individual well of the first well-site while the floating vessel is located at the first well-site simultaneously with the control operations for both the first well-site and the second well-site, and to an individual well of the second well-site after the floating vessel is relocated at the second well-site simultaneously with the control operations for both the first well-site and the second well-site.
