The Cross-stream Active Mooring (CSAM) is a recently proposed novel technique for mooring marine current power systems in large scale. The technique aims to solve major difficulties in the development of ocean current power generation: water depth, seabed geology, meander of current velocity core and typhoons. The technique features two core concepts, "hydro sail active mooring" and "deadweight-on-slope anchor". Hydro sails attached close to generator turbines on a mooring tether, all in submerged floating state, are applied to stablize and adjust the positions of the generator turbines in the sea, while a set of deadweight anchors, holding the other end of the mooring tether, is placed on a submarine slope facing the current to obtain increased gravity anchoring effect. This research explores designs of the hydro sail and the deadweight-on-slope anchor through scale experiments and analysis. In the study of the hydro sail design, two different designs of models based on 1/500 Froude number (Fr) scaling were made and tested in a water tank to study cross-stream mooring and diving capabilities. Multiple models were connected to form a linear array and the linear array was tested in a swimming pool, with a flow generator, to study deployment and stability of a large-scale CSAM system. To study the dynamic operations of the hydro sail, two different 1/250 mobile models were developed and tested in the water tank and the pool. Through remote control of elevators and a buoy/ballast position-shifting mechanism in the mobile models, operations such as changing deployment angle, rolling and diving were studied and demonstrated. Based on experimental observations and analysis of mechanics, major design parameters and criteria affecting the stability and operability of the hydro sail were summarized and an analytical model was developed. In the study of the deadweight-on-slope anchor, basic mechanical analysis, model experiments and construction engineering considerations were applied to design possible structures of anchor blocks that can be assembled on site to achieve required total anchor capacity.
