A Study on the development of Hatchcoverless Container Vessel / 無艙蓋貨櫃船舶發展研究

碩士 / 國立臺灣海洋大學 / 航運管理學系 / 106 / Since the development of containerized ship, speeding loading/unloading and shorten the port stay are the goal pursuit by shipping company and the terminal operator. Especially, when the competition between the carriers becomes fiercely and the fuel price soaring, cost down is the only way of survival. Fast turn-around and cargo operation are the essential of the competitiveness, so that the vessels can sail with slow speed at sea and reduce the oil consumption to cut down the spending. Hatchcoverless container ship then was the realized result of this effort. The hatch cover has its function of water tight and structural purpose. However, the very existing of the hatch cover hinder the cargo operation.
In the 90’, with the open top concept, many European and American shipping companies removed hatchcovers from their container ships speeding the gantry crane spreader in and out of the cargo holds, actually decreased the port turnaround time. The shipping industry then regarded the type of vessel to be “the mainstream of the future”. The International Maritime Organization and the flag state regulated strict building specifications for a hatchcoverless container ship; especially, to cope with green water ingress to the unprotected cargo hatches, required additional equipment equivalent to the same level of safety compare to their conventional counterpart. Nevertheless, these kind of vessels were not expanding further both in their numbers and in size as expected.
This article, through Rogers and Moore’s diffusion of innovation and chasm theory and convinced by the interview of the industrial’s specialists, explored the key hindering factors of the hatchcoverless container ship after innovation but failed to diffuse outside Europe. The research found that all aspects were negative in the five characteristics of an innovation 1. Relative Advantage 2. Compatibility 3. Complexity 4. Trialability 5. Observability. Another five key elements affected its diffusion: the Innovation, Communication Channels, Social System, Time, and Adopters elements are analyzed and found hatchcoverless container ships have no advantage over the traditional container ships on these five elements either. The result of interview with the industrial specialists is consistent with what proposed in Moore’s Chasm theory that argues there are basic differences between the early innovation adopters and the early majority. The latter tend to be realistic and predominantly practical who required more of the successful evidences to enhance confidence, or they are not going to follow and hence causing the innovation fall into the chasm and failed.
Due to nine tiers stacking limitation, the type of hatchcoverless vessel was unable to upsizing. When over 5,000 TEUs, if the cell guide was available, over stacking will most likely to cause collapse of the bottom container. Despite the possibility of split stacking, its complexity involved other maintenance problems. The high raised cell guides not only increased the pick/place time of the container but also the chance of colliding with the spreader. Therefore, in this era of ship maximization, hatchcoverless container vessel could not make an inroad into the shipbuilding market was inevitable.
However, hatchcoverless container vessels can still maintain their size under 5,000TEUs and to be deployed as feeders in the shipping branch line to bring their original quick loading/unloading design into full function.
