Paragraph 4 Buoyancy and Stability

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

(4.1)

Manned submersible craft shall, where appropriate, have sufficient buoyancy and stability to enable a properly trained crew to operate it in all sea states and conditions for which it is intended.

(4.2)

There shall be provided for each craft instructions showing operating procedures in intended service conditions together with emergency procedures. The instructions shall take into account the fully submerged and transient submerging and surfacing conditions together with a full buoyancy condition. The effects of releasing any jettisonable devices either singly or in combination shall be taken into account.
