Study on Guarantee Condition for Super Capability Marine Crane Harbor Test

The testing loads shall be very big and need to be adjustable for harbor test of marine crane with capability over hundreds tones,while the dimensions of the loads must be optimized under the restriction of practical condition onboard and request of the test.Additionally, in order to guarantee the vessel's safety on stability,the anti-heeling measure must be taken out to stand against the bad heel,which derived from turning and luffing of crane with testing loads during harbor test.Taking a successful harbor test of 700t marine crane as an instance after theoretical analysis and study,the article showed the studies,process and results about guarantee condition to benefit similar construction project.
