(1) Different buoyancy materials have different properties and should be selected according to the conditions of use. It should be mainly considered from six aspects: working depth and working cycle, maximum depth, required buoyancy, geometric elements, laying method and installation method.
(2) In order to ensure that the underwater carrying equipment should have sufficient stability under the three conditions of normal working underwater, emergency floating process and floating on the water surface, the buoyancy material should ensure that there is a sufficient amount to provide the corresponding buoyancy when the underwater carrying equipment is designed, and try to install on the upper part of the underwater carrying equipment to ensure a high center of buoyancy.
(3) When underwater carrying equipment is working underwater, in order to ensure a suitable living environment in the underwater carrying equipment, in addition to the necessary heaters and life support systems, the outer shell of the underwater carrying equipment should also be laid with appropriate insulation materials to play a role in heat preservation if conditions permit. Buoyancy material can also be used as an alternative insulating material.
(4) When designing the installation method of buoyancy materials, the convenience of construction should be fully considered.
(5) After the installation of buoyancy materials, it should not affect the disassembly, operation and maintenance of valves, pipelines and equipment.
(6) In order to ensure that the performance indicators of underwater carrying equipment meet the requirements, buoyancy materials should be used as a means to conveniently adjust the mass, center of gravity, floating volume, center of buoyancy and stability of underwater carrying equipment, in the design and installation, full consideration should be given to the buoyancy materials can more easily adjust the installation number and position.
