When ships approach each other, they should keep a minimum area around them clear of other vessels in order to remain safe. The geometrical shape this has been studied since the early 1970s and is defined as ship domain. progress computer capacity then introduction Automatic Identification System (AIS) provides potential further investigate size governing factors This investigation revisits proposes method using data based on 600,000 encounters at 36 locations. It concluded that domain an...
The study presents a methodology that uses AIS data and ship manoeuvring simulator to simulate analyse marine traffic schemes with regard risks for accidents. An event identification method is presented, which needed the accident scenario part of methodology. This based on data, where Great Belt VTS area was used verify Three events could result in ship-bridge allisions were modelled simulated simulator: drifting ship, sharp turning miss point. Monte Carlo perform large number runs,...
This paper proposes a new method to identify active navigational error events for use in ship-bridge allision risk analysis. These errors represent ships, that takes an action putting the ship danger, either by turning at wrong location or setting course point. Accident databases, incident reports and AIS data over several years bridges Scandinavia are used as case studies finding plausible value probability of these kinds events. The main from this is there no universal could be applied all...
In the transition to sustainable shipping, Liquified Natural Gas (LNG), is proposed play a role, reducing emissions of sulphur and nitrogen oxides, particulate matter. However, LNG fossil fuel there an ongoing discussion regarding extent methane slip from ships operating on LNG, challenging assumptions as solution. Here we show another aspect consider in environmental assessment shipping; feeder vessels may spend much 25% their time at sea just running ship ensure pressure tanks are not...
