碩士 / 國立臺灣海洋大學 / 商船學系所 / 99 / Containerized transportation was appeared in 1956. Its unique transportation can fully satisfy the delivery requirements of safety, speed, convenience and economy and has changed traditional transport at sea.
The shipping company has enlarged ship’s capacity and increased the loads on deck to get more economical costs. The latest containerships are able to carry containers on deck stacked up to eight tiers high.
The general principles for the stowage are to stow most of the boxes in holds and stow 40% of the boxes on deck. The containers stowed on deck are secured by the lashings. During ocean passage, higher risks are existed due of long duration at sea and immediate assistances and salvages are unavailable.
To secure the safety for the containers loaded on deck, the lashing bridges play most important role during delivery. The rigid lashings for the containers could reduce the accidents during delivery and make promotions for shipping company’s performances.
The research considers the lashings relative to the stowage on deck is necessary and important for the owners. However, the legislations, risk management and loss prevention are incomplete.
Hence, the research utilizes documentary conclusion combined with practical cases and institutionalized safety assessment to summarize the information issued by worldwide major maritime authorities, insurance companies and classification societies.
Through the analysis of the causes for the accidents of the deck containers and assessment of the elements of major dangers for containers overboard, standard specifications for container lashing gears, as well as the inspections, maintenance and operations of the lashing gears.
The research found all related to human errors except for the defects of the lashing gears.
The results of the research aim at major causes of containers overboard and point out the most effective ways for loss prevention
– the change from Equal Turnbuckle (65 Tons) to double Single (Turnbuckle) (50 Tons) to increase the tension forces of Turnbuckle;
– to heighten the aft lashing bridge;
– to increase whole tension forces by applying Heavy Duty ISO sockets;
The article provides the container carriers the best solutions in risk management and prevention for container loss as well as the improvement for deck lashings and minimization of the accident during delivery.
