Cranes and derricks are used for a variety of purposes in the offshore industry. Maritime construction, salvages, and transport of cargo are just a few examples. An offshore crane differs slightly from a derrick, but they are both used to raise and lower objects and are outfitted on vessels. An offshore crane is a pedestal-mounted elevating and rotating lifting device used to transfer materials or personnel to or from marine vessels and other offshore structures. Cranes are further classified by how many tons they can lift.
The capacity of a crane can differ depending on what structure it is mounted. For example, a crane that can lift 100 tons on a bottom-supported vessel may not be able to lift the same amount when outfitted on a semi-submersible rig. Cranes are also classified by what jobs they have been equipped to perform such as production cranes, intermediate cranes, and drilling cranes.
Derricks are lifting devices that look like a tower that is hinged freely at the base. A derrick is typically controlled by four lines that move by way of motors. The lines usually have a hook on the end, similar to a crane. Derricks that are outfitted onto large vessels are often called floating derricks.
Maritime workers who work around cranes and derricks often fall victim to serious accidents stemming from equipment failures, poor maintenance, and improper usage.
