The present invention relates to a buoyancy control system, and in particular to a buoyancy control system for controlling the buoyancy of an underwater submersible.

The buoyancy per unit area of the first region is greater than the buoyancy per unit area of the second region.

Float Capacity: The flotation capacity has a measure called Newton.

Compartment C2 ensures the container is buoyant at all times.

A buoyancy control system for controlling the buoyancy of a tube may includes generally tubular length of buoyancy control material having a selected buoyancy characteristic.

The beverage accessory device (10) can include a buoyancy adjustment device for adjusting buoyancy of the beverage accessory device.

Each buoyancy-corrected filter tare mass shall be subtracted from its respective buoyancy-corrected post-test filter mass.

When the buoyancy means 15 provided on the periphery of the disk is introduced into the water tank, buoyancy is produced, and the buoyancy is used as the driving force for rotating the disk 13.

The buoyancy control means (7) can be filled with water or some other fluid to regulate its buoyancy.

The length of buoyancy control material may be attached to a section of the length of the tube to adjust the buoyancy of the section of the tube.

A variable-buoyancy marine riser (10) and a method for providing and adjusting the buoyancy for such a riser.

A buoyancy system is also included to adjust the buoyancy of the module for positioning of same at a select position in the water.

Multiple beams can be used to achieve the desired buoyancy.

This buoyancy can be designed to compensate for the weight of the lower sections (2) to make the total buoyancy of the tether closer to neutral.
