Can the nonlinear hydrodynamic be ignored in the process of a ship leaning slowly， and the ship capsized ultimately.

Thanks！

Nonlinear hydrodynamic what?

Ship stability at large angles of heel is usually treated as a quasi-static process, unless one is trying to determine how quickly capsizing takes place.

The nonlinear hydrodynamic what?
  • The nonlinear hydrodynamic forces

If, as you say, the vessel is heeling slowly, then these forces can be neglected.

Thank you for answering my question.
So， The nonlinear hydrodynamic forces can be neglected when a capsized ship is righting ？
