An Analysis of Selected Oil Spill Case Studies on the Shorelines of Canada

Abstract

After an oil spill, oil may wash ashore and there is only a short window of opportunity to respond. Analysis of historical incident data is valuable to guide future responses and cleanup practices. This study summarized the oil spill accidents that impacted the Canadian shoreline and analyzed the related information including location, incident characteristics, and shoreline treatment. Major spills due to tanker accidents in Canadian marine waters fortunately have been infrequent. Most of the accidents have happened on Canada's Pacific coast, accounting for 52% of the total accidents recorded. The Atlantic coast accounted for 39% and the remaining accidents happened in the Arctic region. Regarding spilled volume, 55% of the accidents spilled oil volumes smaller than 100 m 3 . Spilled volumes between 100 ~ 1000 m 3 represent 30% of the incidents and 15% had spilled volume greater than 1000 m 3 . Bunker C fuel and diesel were the main types of the spilled oil, accounting for 33% of the spills, respectively. Within the oil spill accidents impacting Canadian shorelines, marine vessel accidents were the major sources accounting for 70% of the spill accidents. In terms of the shoreline treatment, the commonly employed treatments were manual, vacuum, mechanical, and sorbent removal. The dataset highlighted the significance of a more comprehensive record for response phase details and environmental effects monitoring.

The Mitigation Strategies for Managing the Potential Environmental Risks Posed by Oil and Gas Development on Mangrove Ecosystems in the Coastal Communities

“…The dispersants can be used when oil is spilled at sea. They can be sprayed by aircraft and boats to reduce the droplets' size to boost the oil's thinning and dispersion to lessen the toxicity level (White & Karras, 2021;Feng et al, 2021). The surface washing agents with the flushing technique can be applied together to remove spilled oil effectively (Feng et al, 2021;Bi et al, 2021).…”
