Maritime Traffic Situations in Bornholmsgat

Olindersson F., Janson C. E., Dahlmann J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2015

Vol. 9, no. 1

115--120

Maritime traffic situations is regulated in the Convention on the International Regulations for Preventing Collisions at Sea (COLREGs), but how well are these rules followed by officers on board vessels? When the world shipping fleet grow and the traffic becomes more intensive, the risk of collision increase. By analysing AIS data from vessels in the traffic separation scheme Bornholmsgat during 24 hours in December 2013, 421 traffic situations were found where the passing distance between the vessels were less than 1.5 nautical miles. The compliance with the Convention on the International Regulations for Preventing Collisions at Sea (COLREGs) seems to be good, but the average avoiding action is less than the recommended manoeuver.

Safety of Navigation and Spatial Planning at Sea

Hajduk J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2009

Vol. 3, no. 3

261--266

Until recently the concept of spatial planning concerned only land areas, chaos prevailing at sea in this scope. Vessel routes were selected by the Master on the principle of “freedom of navigation”. It was similar with the submarine routes of pipelines and cables, wind farm construction zones, excavation of aggregates, or the conduct of any human activity at sea. A systemic approach is introduced and preferred currently, which is to take into consideration the natural conditions and human achievements on one hand, and look ahead on the other, systematising procedural ac-tivities and minimising possible conflicts of interests among potential users of the sea.

Safety of Vessels’ Traffic, Bound for Polish Ports

Hajduk J., Montewka J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 2

131--134

Vessels’ traffic in the area of Southern Baltic has not been organized yet. Therefore a risk of potential grounding or collisions is imminent. Organization the traffic by means of passive methods like determination the ships’ routes or traffic separation schemes is one of the better measures to improve navigation safety. Although such activities should take into account interests of coastal countries. The whole area should be considered, and the needs arising from traffic at present and in the future should be met. Due to complexity of above problem, solutions that are fragmentary may lead to deterioration of existing situation and cause new threats for all Baltic countries.

New Development of Ships Routeing in Chinese Navigable Waterways

Hui M., Zhaolin W., Zhengjiang Liu

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 2

127--130

After entering 21 century Chinese waterborne transportation keep high speed development, mmarine traffic order and marine traffic safety become more important issues. In order to enhance marine traffic safety and efficiency, ships routeing systems were implemented in important navigable waters in recent years. After implementation of these ships routeing systems, evaluations on the effects are carried and prove that these ships routeing systems have got obvious effects both on safety and economic efficiency.
