Diving structure and method of deployment of the structure

摘要

A diving bell deployment structure includes a launch tube for a diving bell, the bell having a supporting bell hoist wire. A boom is positioned from the structure to a point vertically above the desired underwater deployment position, and carries a boom hoist wire which is capable of connecting to the bell through the base of the launch tube. Differential pay out of the boom hoist wire and bell hoist wire allows exit of the bell from the launch tube and lateral deployment of the boom and launch tube.
