Description

DETECTION SYSTEM AND METHOD FOR A CRANE
FIELD
This relates to a detection system and method for a crane.
BACKGROUND
Cranes are utilised in a vast array of environments in order to move large and/or heavy items from one location to another.
In the oil and gas exploration and production industry, for example, cranes are used extensively in order to move equipment, cargo carrying units such as shipping containers, and the like, from one location to another. In the case of an offshore installation such as an offshore platform or rig, for example, cranes are used to convey equipment, tools, personnel and supplies to and from support vessels. The crane is also used to move equipment and tools to and from work areas and storage areas on the installation.
The operation of cranes in the offshore environment presents a number of significant challenges.
For example, deck space on a typical offshore installation is extremely limited. As such, the crane is required to perform a significant number of operations, since equipment must be moved repeatedly between storage areas and work areas in order to manage space efficiently.
The nature of offshore operations also requires a significant number of manual operations to be carried out. Consequently, personnel are working and moving in and around the deck while equipment is being moved.
It will be recognised from the above factors that crane operations represent a significant risk to personnel safety operating within the environment.
Although the above issues are particularly prevalent in the offshore environment, the same or similar challenges also affect cranes operating on onshore oil and gas installations, as well as in other environments where cranes are used, including for example tower cranes used in the construction industry.
