Vessel

Abstract

A submersible dredging vessel having a hydrodynamic body optimized for energy-efficient underwater movement. The vessel comprises four primary propulsion units, each incorporating a pump. The vessel has negative buoyancy, causing it to sink when not powered. The vessel comprises a dredging pump arranged to dredge and to control the vertical location in a body of water. The dredging pump can operate in three modes: sink, stable, and rise. In sink mode, the downward force exceeds upward forces, causing descent. Stable mode balances forces, maintaining a constant depth, while rise mode increases upward force to ascend.
