Research on the Detailed Study of Marine Accident Analysis by National Transportation Safety Board (U. S. A.)

本研究的最终目的是通过对美国海上事故调查制度的详细研究，并与我国的海上事故调查制度进行比较，提出如何完善我国的海上事故调查制度，以减少海上人员伤亡。据悉，美国国家运输安全委员会（NTSB）自1975年成立以来一直卓有成效。它每年出版大约十份海上事故报告（MARs）。这意味着NTSB每年只调查非常严重的海上事故。NTSB还向各部委和/或相关方发布建议，以改进其系统，并有权执行这些建议。1990年，我们试图获得1975年至1989年的所有过期的MARs和推荐的MARs，并从其中选择了三份调查陆桥相关船舶灾难的MARs进行了详细的研究。这些微小的研究是为了应用于我们（日本）在日本建造或在建的几座巨大桥梁周围的船舶操作安全。1991年，我们解决了MAR的问题，“1989年3月24日，美国油轮MON VALDEZ在阿拉斯加瓦尔迪兹附近的威廉王子湾布莱礁搁浅”。对我们来说，这是一项紧急的补充研究，因为这次事故对阿拉斯加海岸造成了如此深远的影响，我们认为，这对人们保护地球的运动来说是及时的。我们出版了这个MAR的日文译本（225页）。

Final aim of our research is to propose how to improve our marine accident investigation system in order to reduce the number of casualties at sea, by studying minutely the United State's system and comparing it with ours. It is known that in the U. S., National Transportation Safety Board(NTSB)has been working effectively since its founding in 1975. It has been publishing annually about ten Marine Accident Reports(MARs). This means that NTSB investigates only very grave marine accidents every year. NTSB also publishes recommendations addressed to the ministries and/or the parties concerned to improve their systems, and it has the authority to have then fulfilled. In-1990, we tried to get all the back numbers of MARs and recommendations from the year of 1975 to 1989, and studied minutely three MARs selected from among then which investigated ship disasters related with land bridges. These minute studies were to apply the essence to our(japanese)shiphandling safety around the several gigantic bridges constructed or under construction in Japan.In 1991, we tackled the MAR, "Grounding of the U. S. Tankship MON VALDEZ on Bligh Reef, Prince William Sound near Valdez, Alaska March 24, 1989". This was the urgent additional research for us because the accident gave such a profound effect to the coast of Alaska and it is timely, we believe, to the people's movement for the protection of the EARTH. We published a Japanese translation(225 pages)of this MAR.
