226 International Antifouling Conference 2023

Hull performance

Shipowners and ship managers are seeking solutions to manage hull performance more effectively. Why is that? It’s because they want to make their fleet more sustainable, and they also want to save money. Les effective hull performance > more fuel and more emissions.

Port logjams increase biofouling, harming fuel efficiency, marine life — study

Port congestion and increased idle times make biofouling worse, according to a recent I-Tech study.

Biofouling — the accumulation of barnacles, plants and algae on ship hulls — is only getting worse as waters warm and as port congestion increases idle time, according to a recent I-Tech study.

As it builds up, the biological material adds drag and reduces fuel efficiency, costing shippers money and releasing greenhouse gases unnecessarily. The study found that the risk of biofouling accumulation increases significantly when a vessel idles or is in warmer water.

“Fouling takes place significantly...

New research shows growing impact of biofouling as waters warm and ships idle for longer, with 100% increase in idling vessels since 2009

New research shows growing impact of biofouling as waters warm and ships idle for longer, with 100% increase in idling vessels since 2009

Covid pandemic and port congestion coupled with warming waters means ships are at increased risk from biofouling. Advanced technology needed to combat efficiency loss as new rules loom.

Percentage of ships subject to ‘fouling idling’ increased constantly since 2009 from a starting point of 25.4% to a peak of 35.0 % in May 2020.At the peak of idling in 2020...
