Fears over health and environmental impacts
Experts have shared their fears over the health and environmental impacts the disaster could have.
Dr Jennifer Allan, an expert in global environmental politics at Cardiff University, said: "It's a disaster in every sense of the word. The health and environmental effects will be short and long term, local and regional.
"The jet fuel will be harmful to local wildlife and beaches and the livelihoods that rely on them. In the long term, it could move up the food chain; for example, from fish into birds and people.
"A rapid response is required and there are longer-term questions of who is liable for the cleanup operations and, potentially, the lasting health and environmental effects."
Dr Leslie Mabon, an expert in climate risk and infrastructure in coastal and marine environments, said knowing what exactly both ships were carrying "and how much leaked into the sea," is going to be crucial to get a clearer picture of the environmental and economic effects of this disaster.
The senior lecturer in environmental systems at The Open University said: "However, there's plenty of evidence globally that can tell us what we need to be looking out for.
"First and foremost is the effect on the marine and coastal ecosystem. It's close to nesting season, so puffins, gannets, kittiwakes among others could be flying around the area and could be exposed to oil or petrol.
"Similarly, there are dolphins and seals. This is also a rich fishing environment with the Grimsby fishing port nearby, and there could be economic consequences if fishing has to be stopped or scaled back."
