Hempel A/S, has increased its commitment to supporting the maritime industry’s shift to ever more sustainable operations by joining the Global Industry Alliance (GIA) for Marine Biosafety.
The GIA, created under the International Maritime Organization’s (IMO’s) GloFouling Partnerships project, is a cross-sectoral platform for collaboration. Following Hempel’s membership, the GIA comprises 13 private companies that work with governments, the IMO and other non-governmental organisations to increase awareness of the environmental implications and risks associated with biofouling on ships hulls, identify common issues, and foster solutions for mitigation. The alliance also informs policy developments and shares technical expertise within NGOs.
“At Hempel, we are very pleased to be joining the Global Industry Alliance (GIA) for Marine Biosafety. We believe that strong collaboration between all stakeholders – governments, NGOs and the maritime industry – is needed to identify challenges and accelerate solutions to decarbonise the maritime industry and protect marine environments. As a provider of hull performance solutions that can help prevent the build-up of invasive species on hulls, as well as reduce the fuel usage and carbon emissions of ships, we look forward to taking part in this collaboration.”
Alexander Enström, Executive Vice President and Head of Marine.
Biofouling on ships’ hulls can affect the environment in two ways. Ships sailing across different regions can facilitate the unintentional spread of invasive aquatic species, one of five largest threats to marine biodiversity. Further, biofouling build-up on a ship’s hull creates drag and can significantly reduce efficiency levels as more fuel is required to propel the vessel through the water.
Members of the GIA include marine coatings companies, in-water cleaning service providers and marine growth preventive systems, shipping companies and technical organisations. The International Association of Oil & Gas Producers also has observer status within the group.
The GIA was set up as a public-private partnership by the GloFouling Partnerships project in June 2020. The Project is part of the wider efforts undertaken by IMO, in collaboration with the Global Environment Facility (GEF) and the United Nations Development Programme (UNDP), to protect marine ecosystems from the negative effects of invasive species.
The programme is also in line with the IMO strategy to reduce greenhouse gas (GHG) emissions from shipping by at least 50% by 2050. By limiting biofouling on a ship’s hull, GHG emissions are reduced and operational efficiencies can be achieved.
Understanding Biofouling on Ships’ Hulls
Hempel is helping prevent biofouling on ships’ hulls, let us first understand what biofouling is. Biofouling is the accumulation of microorganisms, plants, algae, and animals on surfaces submerged in water, such as ships’ hulls. Biofouling can cause various problems, including increased fuel consumption, reduced speed, and damage to the ship’s structure. It can also lead to the transfer of invasive species, causing environmental and economic damage.
The Impact of Biofouling on the Shipping Industry
Biofouling is a significant problem in the shipping industry, costing billions of dollars every year. It is estimated that biofouling increases fuel consumption by up to 40%, resulting in higher emissions of greenhouse gases and other pollutants. In addition, biofouling can cause delays and additional costs due to cleaning and maintenance.
