A deep-sea apparatus for retrieving deep-sea nodules is provided. The deep-sea apparatus includes an opposer configured to provide static buoyancy to the deep-sea apparatus. The deep-sea apparatus further includes a thruster coupled to the opposer, the thruster configured to provide dynamic buoyancy to the deep-sea apparatus. The deep-sea apparatus also includes a variable load and a gas supply system that includes a gas cylinder connected to a gas valve of the opposer, where the gas supply system is configured to inject a predetermined amount of gas from the gas cylinder to the opposer in response to a change in a vertical position of the opposer caused by a mass change in the variable load.
