Research On Combination Berthing Of Large Ship In Shulang Lake Zhoushan Port Ore Pier

Ningbo Zhoushan Port Qushan Area,the Shulang Lake Ore Transit Terminal,the lengths of the 1#and 2#berths are different,the number of mooring equipment is asymmetrical,and the distribution of the piles in the common area between the berths is not reasonable,such as insufficient number of piles.Moreover,there are many contradictions in the use of dock mooring equipment in different ship types.Due to different ship types,different berthing positions and changes,dock mooring equipment needs to be considered for rational use.The combined berthing mode and mooring method of large ships are the first solution after the 2#berth is put into production.To ensure the stagility of the large ship after berthing and the force of the cable,and at meantime not to cause cross-belt between the two adjacent ships.This paper studies the combination berthing scheme and stagility of the berths of the 1#and 2#unloading berths of the terminal.This paper combines the actual characteristics of the wharf and the vessels to design a large ship combination berthing scheme to solve the problems of insufficient crossover tethers and common use of cable piles.Combined with influencing factors,the two berths were berthed and stagilized,and the feasibility analysis report and countermeasures were made.To avoid the cable crossing between ships,ensure the uniformity of the longitudinal and lateral forces of the cable,and cope with the unfavorable factors of the water environment,ensure the stagility of the ship,the operation of the loading and unloading operations and the safety of dock.This paper uses the OPTIMOOR to simulate the mooring constraints of the program.Since the comprehensive evaluation of mooring safety,the comprehensive risk assessment of combined mooring safety is carried out to verify the feasibility berthing of large ship combination in the terminal,and relevant safety recommendations and safeguard measures are proposed.
