Videometric systems and methods for offshore and oil-well drilling

摘要

A crane control system for determining a suitable real-time operating regime for a crane arranged to lift cargo from a marine vessel, the system includes an imaging means associated with the crane, a processing means, and a memory means. The imaging means is arranged to capture images of the vessel when it is located generally below the crane and within the operational range of the crane. The processing means is operable to calculate from the captured images movement parameters characterizing the movement of the vessel relative to the crane. The memory contains performance data representative of the performance characteristics of the crane and cargo data representative of the weight of individual items of said cargo. The processing means is further configured to compare the calculated movement parameters to the performance data and the cargo data and to determine from said comparison a safe operating regime for the crane.

1. A crane control system for determining a suitable real-time operating regime for a crane arranged to lift cargo from a marine vessel, the system comprising:
an imaging means associated with the crane, wherein said imaging means is arranged to capture images of the vessel when it is located generally below the crane and within the operational range of the crane; processing means operable to calculate from said captured images movement parameters characterising the movement of the vessel relative to the crane; and memory means, wherein said memory contains performance data representative of the performance characteristics of the crane and cargo data representative of the weight of individual items of said cargo, wherein said performance data comprises a relationship between a maximum load of the crane and a sea state; wherein the processing means is further configured to:
compare the calculated movement parameters to the performance data and the cargo data and to determine from said comparison a safe operating regime for the crane;provide a display of a cargo deck of the vessel comprising a graphical overlay that divides the cargo deck into sectors;identify, based on the determined safe operating regime, one of the sectors from which it is safe to lift cargo; andhighlight, on the display, the one of the sectors from which it is safe to lift cargo.
