Drilling or work-over rig comprising an operational control and/or state unit and a computer-implemented method of providing operational control and/or state

Abstract

A drilling or work-over vessel () is disclosed comprising a number of operational equipment (), wherein the drilling or work-over vessel comprises at least one operational control and/or state unit () comprising at least one processing unit (), wherein the at least one operational control and/or state unit () comprises or are in connection with a memory and/or storage (), and at least one sensor unit (), wherein the at least one sensor unit () is adapted to obtain one or more measured physical values and to provide data representing the one or more measured physical values and/or derived values thereof to the at least one operational control and/or state unit (), the memory and/or storage () comprises a data representation of a computational physics model of at least a part of the drilling or work-over rig, and the at least one processing unit () is adapted to derive data representing an estimation of one or more physical states (such as defined by limits of forces, relative motion between operational equipment and vessel, or between other two pieces of operational equipment) estimated to act on at least one operational equipment () in response to the data representing the one or more measured physical values and/or derived values thereof as provided by the at least one sensor unit ().
