If additional buoyancy is required, activate the victim's life jacket (inflate BC).

Its most effective traveling mode was close enough to the ground so that the backwash of its gaseous emission provided additional buoyancy.

Thus hydrogen's additional buoyancy compared to helium is:

These vests may not be fully suitable for other purposes, such as whitewater paddling where additional buoyancy is required due to the higher flow of water.

The bridge superstructure is integrated with floats to provide stability and additional buoyancy.

A second buoy can be used to provide additional buoyancy if one buoy is dragged underwater.

Lengthening the submarine would create additional buoyancy, though at a cost of €7.5m per metre.

The workaround selected will be to install external tanks for additional buoyancy.

When inflated these provided additional buoyancy, and enabled the 30 tonne tanks to displace enough water to permit them to float.

The designer felt that using compressed helium would provide additional buoyancy, requiring less volume than an unpressurized dirigible.
