North Atlantic vessels will put a new hull paint developed in NS to the test

Nova Scotia to the test.

Key Takeaways:

  • Tests on lobster boats revealed a 20% reduction in fuel consumption and lower noise levels.

In 2022, larger vessels will test the product’s protective and anti-fouling properties in the North Atlantic’s harsh, open ocean conditions, putting a super-slick hull paint developed in Nova Scotia to the ultimate test.

Graphite Innovation and Technologies’ strong, slippery, and non-toxic hull paint is graphene, a carbon-based nanomaterial. The coating aids in the prevention of marine fouling, which occurs when aquatic organisms such as barnacles adhere to the hull, improving the flow of water against the vessel and making it more efficient.

Transport Canada-funded tests on six Cape Islander lobster boats in Nova Scotia revealed a 20% reduction in fuel consumption and lower noise levels.

The hull paint is now being applied to much larger vessels, such as the 193-meter Oceanex Sanderling, a roll-on-roll-off ship transporting cargo to Newfoundland and Labrador 60-metre Baffin Fisheries trawler Inuksuk, which operates off the coasts of Greenland and Baffin Island.

“The vessels operated by Oceanex and Baffin Fisheries are much larger and move at a much faster speed than the smaller inshore fishing boats previously tested under our contract with Transport Canada,” said Mo AlGermozi, president of Graphite Innovation and Technologies.

“This is much more comparable to the larger shipping vessels that we are targeting as key customers because shipping fleets are most interested in reducing fuel costs and improving their environmental impact.”

Each year, the Oceanex fleet of three ships transports roughly half of the goods into the province of Newfoundland and Labrador. The Sanderling, which is based in St. John’s, will enter a regularly scheduled dry dock at the end of December to have a large patch of the hull coated with GIT hull paint.

After it re-enters service at the end of January, quarterly underwater surveys will be conducted to compare the results to the existing paint.

“We believe it will be clear how well this performs against the other coating that is currently on the vessel,” said Matthew Hynes, executive vice-president of Oceanex.

He anticipates that the coating will last at least five years.

“At the end of the day, it’s a steel ship operating in saltwater, traversing ice and other obstacles. We must ensure that the hull is protected. Number two, it must run efficiently, which means there must be no growth or fouling on the bottom.”
