Object and purpose of research. This paper studies design technologies for large sea-going research vessel with onboard helicopter and deepwater submersible vehicle (DSV) launched/recovered via the moonpool passing through hull and superstructure. The purpose of this study is to ensure permanent helicopter base aboard research vessel, as well as DSV launch/recovery via the moonpool in the open sea. Materials and methods. The study was intended to find an optimal even-keel trimming solution for a ship with spacious forward moonpool for large deepwater submersibles, as well as to develop an optimal procedure of DSV launching/recovery. Main results. The study yielded an original technological solution for even-keel trimming of ship with large forward moonpool, as well as an original technology for Bester-1 DSV launch/recovery. Conclusion. The solution suggested in this paper enabled even-keel trimming of ship without prejudice to her propulsion performance. The newly developed technology of Bester-1 DSV launch/recovery via the moonpool will considerably expand the spectrum of tasks handled by the research ship, including the operations in polar waters.
