Harbour Porpoise Presence near Oil Tankers
Harbour porpoises (Phocoena phocoena) are thought to be “shy” animals that are easily disturbed by underwater noises. There is concern that sources of anthropogenic sound, especially those associated with shipping and pile driving, will drive porpoises away from their preferred habitat [1]. A recent study, however, found that harbour porpoises were occasionally present within a few hundred m of...
متن کاملCasualty Rate Prediction for Oil Tankers
A model of oil tanker casualties is presented which permits an e.upected casualty ratefor each tanker to be calculated based on its age and casualty history. These expected rates are shown co be good predictors of both the actual cosuoly expertence and the probability of total loss. The model is based on thefindings that 1) the casualty behavior of an individual tankerfollows a Poisson distrtbu...
متن کاملExposure of the deck crew to carcinogenic agents on oil product tankers.
Work on deck on eight oil product tankers was examined. The purpose was to evaluate the need for improvement of the working environment to reduce the risk of occupational cancer. Benzene, polyaromatic hydrocarbons (PAHs) and organic lead compounds were sampled, and the crew answered a questionnaire on acute health effects. By area monitoring, benzene was generally found to be in the range from ...
متن کاملA probabilistic model for accidental cargo oil outflow from product tankers in a ship-ship collision.
In risk assessment of maritime transportation, estimation of accidental oil outflow from tankers is important for assessing environmental impacts. However, there typically is limited data concerning the specific structural design and tank arrangement of ships operating in a given area. Moreover, there is uncertainty about the accident scenarios potentially emerging from ship encounters. This pa...
متن کاملA Sustainable Model For Optimal Dynamic Allocation Of Patrol Tugs To Oil Tankers
Oil tanker traffic constitutes a vital part of the maritime operations in the High North and is associated with considerable risk to the environment. As a consequence, the Norwegian Coastal Administration (NCA) administers a number of vessel traffic services (VTS) centers along the Norwegian coast, one of which is located in the town of Vardø, in the extreme northeast part of Norway. The task o...
