The safety of the hull structure is a foundation stone for guaranteeing the operation safety of the ship. In order to improve the safety of the ship structure, designers often design the ship structure by using methods such as standard calculation, finite element check, pool model test, structural member loading test and the like, so as to ensure that the strength of the ship meets the load action in the actual storm environment. And a few scholars install strain sensors in the real ship structure to study the structural stress change rule in the actual sailing process.
However, the actual sea wave environment has strong randomness, so that designers cannot accurately evaluate the structural stress conditions under different sea conditions, and for the sake of safety, the design is conservative, the safety redundancy is high, the weight of the ship body is heavy, and certain economic loss is caused to the shipowner.
