A method, system, and computer readable medium configured to store instructions executable by a processor to identify personnel locations and/or conflicts between personnel and movable machines. The method includes creating, in a database, a dimensional map of an offshore unit, tracking, in the database, locations of the entities in the dimensional map of the offshore unit by receiving at least wireless monitoring from wireless devices associated with both the entities and the offshore unit, obtaining, with a programmable control device, operating parameters of a movable machine operating on the offshore unit, calculating, with the programmable control device, a dynamic movement zone that changes by moving dynamically in the dimensional map in the database based on the operating parameters of the movable machine, detecting, with the programmable control device, a conflict of at least one of the tracked locations interfering with the dynamic movement zone of the movable machine, and outputting the detected conflict with the programmable control device.

Personnel location monitoring

A system and computer-implemented method is used for tracking crew members on an offshore unit. A static map is created in software and interfaces with a network of receiver nodes physically installed at a predetermined set of measurements to provide coverage to designated areas to locate and identify crew members, who have or wear Bluetooth beacons. During operations, crew members are located and identified in real-time through the network of receiver nodes installed over prespecified coordinates. Cameras and visual recognition processing can operate in the designated areas. The designated areas can include muster stations for crew members to gather in an emergency or can include designated areas in which personnel are restricted while equipment is operating or moving.

A first permissible operating range of the self-elevating vessel is determined based on a first structural analysis of the self-elevating vessel under a first set of conditions. A structural utilization ratio of the self-elevating vessel is determined based on a second structural analysis of the self-elevating vessel under first and second sets of conditions. Safety of lowering the self-elevating vessel from an elevated state to a first hull draft level is determined when the structural utilization ratio is less than a predetermined value. Safety of lowering the self-elevating vessel from the first hull draft level to a second hull draft level is indicated when positional displacement data obtained while the vessel is at the first hull draft level indicates that the positional displacement of the self-elevating vessel while at the first hull draft level is within the first permissible operating range.

Multi-stage coming off location technology

A system and computer-implemented method is used for operating a crane on an offshore unit on which entities (e.g., personnel and/or equipment) operate. A dimensional map of the unit is created so locations of the entities can be tracked in the dimensional map of the unit. For example, wireless monitoring is received from wireless devices associated with both the entities and the offshore unit to perform the tracking. Dynamic operating parameters of the crane are also obtained while the crane is operating on the unit. These parameters can be received remotely from the crane. A programmable control device calculates a lifting zone that moves dynamically in the dimensional map based on the parameters, detect a conflict of a tracked location interfering with the zone, and outputs the detected conflict for appropriate action.
