Northern Spill Technology

This site is the new home of Extreme Spill Technology (EST).
Both EST and NST are companies founded by David Prior,
creator of the technology and patents.


NST will provide industry and government agencies around the world with the next generation of oil spill response vessels for every stage of oil exploration, production and transport. Our vessels are the first with real capacity to immediately recover up to 95% of spilled oil in real offshore conditions including outer harbours and approaches, coastal waters and the open ocean.


NST and EST patented technologies and innovative vessel designs will enable offshore oil industry and government regulators and agencies to pursue a new standard of environmental stewardship and social responsibility. With EST vessels integrated into response plans, risks and costs to both industry and communities will be greatly reduced when compared with conventional oil spill response plans based on current remediation strategies.
