近年、新水先法が施行され水先制度や水先人教育が大きく変わり、乗船経験の極端に乏しい若者にも三級水先人になる機会が与えられた。三級水先人は、本格的な業務に就くまでの過程で、水域や岸壁ごとに限定解除を受けることになっている。しかしながら、各水域や岸壁の着岸に対する難易度は水先人の経験による感覚に依存しているのが現状である。本研究では、ベテラン水先人を対象に階層分析法を用いることで各水域、岸壁の着岸難易度を定量的、総合的に評価することを提案する。

A pilotage is one of important factors in order to keep a safety and a security of main harbors in Japan; however, pilots' accidents sometime happen while they work. The pilots' accidents happen well for the transfer to/from the vessel/pilot boat; pilots and pilots' associations do their best for reducing the accidents under International Maritime Organization (IMO) convention. In other word, a safety measure for the transfer is the important subject for pilots. The purpose of this paper is to evaluate a pilot's physical performance while their work using large model sensors (acceleration sensors), and we read characteristics for the transfer. This research is first challenge to evaluate the pilots' performance in real situation. If their performances become clear, we will be able to tackle the new method for reducing accidents.

A few of marine pilots have gotten severe personal accidents on board and closed their businesses. Their pilot associations have been struggling to keep their safety on board. However, their situations are not improved dramatically nowadays. In this paper, we investigate into the marine pilots' personal accidents on board for 20 years from 1989 to 2008. From the results of the investigations, we propose methods for keeping marine pilot safety on board. The results of the investigations show that their dangerous behavior happens between a pilot ladder and a pilot boat transfer. For avoiding such kind of dangerous situations, we propose to develop a supporting device for receiving falling them.

Recently, the environmental destruction problems are international social problems. The transport systems are important elements for the conservation of the air environment. The environmental parameters are CO_2, NO_x and SO_x from the transport systems. This paper describes the effects of the reduction for CO_2, NO_x and SO_x by systematizing ship's navigation schedule planning (Eco-navigation systems: Eco-navi) which can utilize the tidal current and the wind in inland sea. The Eco-navi consists of three sub-systems: "Cell decision system", "Current calculation system", and "Wind calculation system". We define 'Cell' as the minimum unit for calculating the hours underway. The cell, latitude: 1' ×longitude: 1', has the current and wind information. We can calculate the hours underway by utilizing the current/wind effects. We calculated the hours underway for the neap tides, ligging the tides and the spring tides of 'Kobe' to 'Hesaki' by using the data of training ship Fukae Maru, and its time saving ration is 5.1%, 9.6%, and 14.8% respectively, even if we reduce the system errors (3.8%). We proposed about 5% reduction of air pollution (CO_2, NO_x, SO_x) from the vessel in inland sea.
