And measuring, recording and analyzing the ocean current condition of the water area salvaged by the sunken ship to obtain the tidal current flow speed and flow direction data of the required operation water area for estimating the energy carried by the tidal current of the operation water area. Tidal current energy is the kinetic energy carried by seawater in the fluctuating tide cycle motion, denoted by E:
wherein the unit of E is: w, ρ is the seawater density, unit: kg/m3And v is tidal flow velocity, unit: m/s, s is the tidal cross section, unit: m is2。
The energy flow density of the tidal current is the tidal current energy passing through a unit area, and is represented by e:
wherein the unit of e is: w/m2ρ is the density of seawater, unit: kg/m3And v is tidal flow velocity, unit: m/s, s is the tidal cross section, unit: m is2。
The energy flow density is an important index for representing the tidal current energy strength or the abundance degree of tidal current energy resources in a certain sea area, and the larger the e is, the higher the tidal current energy at the position is, the richer the resources are.

F＝ρ×g×vrow board
Wherein the unit of F is: n, ρ is the seawater density, unit: kg/m3G is gravitational acceleration, unit: n/kg, vRow boardIs a buoyancy tankVolume of drained water, unit: m is3。
