Vietnam can search for the culprit causing oil spill on the sea

The Vietnam General Department of Sea and Islands completed the Oil-Sensitive Map System, along with a program to simulate oil slicks to track down culprits causing oil spills on the sea.

According to the Department of Marine Resources and Environmental Investigation and Control, under the Vietnam General Department of Sea and Islands (Ministry of Natural Resources and Environment), 70% of the annual number of ships running through Vietnam's waters is oil tankers. .

In only two years from 2007-2009 there were 12 large oil spills and more than half of the cases could not find a cause. Therefore, the issue of accountability and reimbursement is not possible due to the lack of a legal basis, as well as a technical documentation system to monitor and trace causes and culprits causing oil spills.

In order to overcome this situation, the Vietnam General Department of Sea and Islands has completed the Oil Sensitive Map System, along with the simulation of oil slicks in the Southern and Southwestern sea areas that will support the monitoring. close, search for the culprit causing and troubleshooting.

With this scenario one can identify the region
The most sensitive to bring timely response force.

The scenarios for simulating oil slicks will be given in windy field conditions, seasonal flow fields, combined with environmental forecast data NCEP Prediction Monitoring Center (USA) regularly monitoring wind fields, Air, humidity around the globe, setting up meteorological school to provide 6 hours / time and processing data completely automatically.

Next, using a numerical model of the US weather forecast interpolation on the sea wind field, calculating the spread, change process, the spread of ocean waves will determine the area affected by the spill. as well as finding the right culprit causing the oil spill.

Together with the above technical system, the Vietnam Marine and Islands Management Research Institute continues to study the process of using dispersants for Vietnamese waters, a chemical when spraying on oil stains that will make manure. Disperse oil particles, reduce oil concentration and reduce oil toxicity to the ecological environment.

The waters of Vietnam connect the Pacific Ocean and Indian Ocean, through the wide straits, which are one of the maritime axes with great traffic flow.

Oil spills with large volumes of oil over 700 tons are mainly due to the process of shipping oil at sea. Since 1989 there have been about 100 oil spills due to ship accidents, these accidents have all been discharged into the sea from a few dozen to hundreds of tons of oil.

Oil spills usually occur in March and April every year in Central and May, June in the North.
