A method of adjusting buoyancy of a UUV 10 comprises measuring buoyancy drift of the UUV when underwater. After docking the UUV with a subsea station 16, a quantity of a flowable buoyancy-adjustment material 72 held onboard the UUV is changed by transferring that material from the station to the UUV or from the UUV to the station. A buoyancy adjustment system for a UUV is also disclosed that comprises an onboard tank 44 for holding a variable quantity of the buoyancy-adjustment material and upwardly-opening 50 and downwardly-opening 52 passageways communicating with the tank for transferring the buoyancy-adjustment material to or from the UUV. The subsea station comprises a dock 28 for docking a UUV, a holding tank 56 and 58 for holding the buoyancy-adjustment material and at least one upwardly-opening 64 or downwardly opening 60 passageway, aligned with the dock and communicating with the holding tank for transferring the buoyancy-adjustment material to or from the docked UUV. |
