This work is focusing on a buoyancy system in anautonomous underwater vehicle, and the purpose is topresent a theoretical proposal on how the system indetail and in general can be changed to improve theaccessibility to its internal components and to make itmore robust. The largest part in this work is to simplify thehydraulic system, not only to make it more accessiblebut also to mitigate the risk of leakage due todifficulty of handling pipes and couplings. To reacha solution, interviews as well as litterature studieshas been made to identify specific problems. Thecollected data has then been discussed in order tocombine each specific solution to a final construction.The construction is presented with motivation, calculationsand 3Dmodels. The logical thoughts behind the finalconstruction are also presented for easy understanding ofthe choices being made. The design proposal differs from the earlier, two of themajor changes are that the old single direction the pump isreplaced with a new dual directional pump, and the valvemanifold is replaced with a single valve. In addition, allcomponents are now mounted in a chassis that can be easilylifted out from the hull, making the mounting and servicework on the system easier
