The invention provides various types of aircraft carriers, warships, submarines and offshore platforms each with a correcting device with high efficiency, load removal, swing stoppage and turnover resistance through a load-removal self-balance swing reducing device, a load-removal airbag pad floating device, an external suspended adjustable weight balancer device, a correcting plate and wing type swing reducing plate device, a submarine ascending / descending accelerating device, an accelerated underwater suspension self-balance control device, a transversely-propelled whole-body fast moving-mooring-docking device, a safe urgent-deceleration fast-lag electric oar device and a gyroscopic magnetic-field inertia movement weight balancer device. The invention has the effects that according to the structure, the swing on six degrees of freedom of ships, warships, aircraft carriers and various offshore platforms can be solved comprehensively, so that traveling ship bodies are ensured to timely and safely avoid sudden barriers, therefore a complete and efficient swing reduction system is formed, several problems in the fields of navigation and ships are solved, the balance stability and safety of ships, aircraft carriers, submarines or aircrafts and spacecrafts in the aerospace field are improved, the ability and confidence of humans for handling offshore or aviation activities are largely promoted, swing reduction is changed into swing prevention or swing stoppage, and the aircrafts in the air never crash due to unbalance.
