Abstract
In order to acquire the true figure of vessels going through the Soya (La Perouse)
Strait, an AIS (Automatic Identification System) receiving station was set up in
November 2008 and data has been successfully stored. Both static and dynamic
analyses were conducted. First, the Strait was divided into eight sections and
directions and the numbers of vessels crossing each section were counted.
Second, the area was divided into 1 km square grids, then each grid was
examined as to whether two or more ships were in the same grid at the same
time. As a result from the first analysis, vessels are crossing both bounds of west
to east and east to west in each section. Large vessels with hazardous materials
are likely to be congested in the northern part of the strait to keep away from the
Reef Nijo and save petroleum, and dangerous crossings have actually occurred
periodically. Lane separation or other traffic regularity needs to be established
through international cooperation.
Keywords: automatic identification system (AIS), risk assessment, Soya (La
Perouse) Strait, Sakhalin oil and natural gas developing projects.
1 Introduction
The Sea of Okhotsk is part of the western Pacific Ocean surrounded by
Kamchatka Peninsula, Kuril Islands, the island of Hokkaidō and the island of
Sakhalin. In the Sea of Okhotsk off the island of Sakhalin, one of the largest oil
and natural gas developing projects has been underway in earnest from the late
1990s. It is known that there are nine developing projects around Sakhlin Island
Keywords
