摘要:
A method of forming a wall of a floating caisson is provided, which comprises: providing a slab (110) on a submersible platform (20); providing one or more base supports (130) on top of the slab (110), the base supports (130) having a first outer surface and a second outer face; forming a first wall portion (121-124) by spraying concrete on the first and the second outer faces; lowering the platform (20); and forming one or more subsequent wall portions (121-124) on the first wall portion (121-124). Also disclosed are apparatuses (70) for constructing a floating caisson and floating caissons.

An underwater base (800, 900) handles an autonomous underwater vehicle (932). The underwater base (800, 900) includes a storing part (820) configured to store the AUV (932); a control part (810) configured to control the storing part (820); and a support part (830) configured to support the control part (810) and the storing part (820) and to prevent a burial of the underwater base into the ocean bottom. The control part (810) is further configured to guide the AUV (932) while approaching a desired target position (980) on the ocean bottom.
摘要:
The present system provides a buoyancy system for moving an object (401) in a body of water. The system comprises at least one inflatable body (17) which, when inflated, increases the buoyancy of the object (401), and an inflation apparatus (37) to inflate the at least one inflatable body (17). The system also comprises an activation system (21) to activate the inflation apparatus (37). Upon activation of the activation system (21) the inflation apparatus (37) causes gas to flow to the at least one inflatable body (17), causing the object (401) to move. The inflation apparatus may comprise a hydrostatic sensor (407) and pressure relief valves (91, 93) to automatically control the depth of the object and a guide wire (411) to aid locate the object on the surface.
