碩士 / 國立海洋大學 / 航運技術研究所 / 86 / ABSTRACT - The grounding of vessels usually causes injuries to
seamen and passengers, damages to cargoes, pollution to coastal
waters, and also destroys marine resources. That following wrong
position vessels move near coastal line or enter shallow water
is the main factor contributory to the grounding. There is no
accurate radio aids to navigation in Taiwan area. Therefore,
vessels to fix position must depend on radar, lights or GPS. The
topography of west coast of Taiwan is straight and sandy so that
the electric wave of radar cannot reflect well. Consequently,
the shape of coastal line on radar screen does not coincide with
it, and ship position is easily fixed by mistake. Lighted visual
aids to navigation become significantly important. This study
has referred international criteria of installing lighted visual
aids to navigation in order to evaluate the effectiveness of
existing lights around Taiwan coast. The evaluation is carried
out by directly observing the light intensity from ships through
coastal navigation, and by questionnaire investigating the
requirements of mariners to lights. The observation can analyze
the exactly luminous range of lights to compare with the nominal
range for finding the deficiency. The study also introduces an
improvement scheme with continuous lighted visual aids for
navigational safety in the vicinity of Taiwan waters to help
ship getting accurate position and decrease grounding risk.
