Marc Raymond, CEO, aqua-tools, explained: “Based on our success in supplying quick water monitoring test kits to other industrial sectors, we are now able to provide similar scientific expertise to the maritime industry, within the framework of risk and quality management. “Despite constantly changing regulatory requirements and technologies, aqua-tools Rapid Microbial Solution provides the global shipping industry with protocols adapted to their products and processes, as well as the extensive support water sampling and testing requires.” The training and support procedures aqua-tools has implemented is intended to help the industry implement ATP-metry technology (sampling, analytical protocols, interpretation, microbiological mapping, etc.) to best fit a company’s specific needs. “Not only can we offer the training and support the industry requires but we can provide a comprehensive technical evaluation of the quality of water and fluids,” added Raymond. “Our laboratory in Paris can also help identify the best analytical strategy and recommend the best ATP-metry kits and protocols for any ballasting situation. We can also provide information on how best to optimise ballast water disinfection procedures, with the goal of reducing the use of biocides and its consequent impact on the environment. For instance, our recommendations can determine the optimum dose to use and the most useful ATP-metry kits for confirming the effectiveness of a shipowner’s ballast water treatment strategy.” The France-based water specialist can also advise companies that specialise in developing new eco-friendly solutions for disinfecting water and other fluids to help them identify the most active compounds and determine dose-response curves for managing biological contamination. Type Approved to IMO MEPC 227 (64) MARIPUR NF CLARIMAR MF BIOFOULING MEASURE SHOULD BE TAKEN TO PREVENT BIOFOULING ADVISES UK P&I CLUB The UK P&I Club’s Madlene Wangrau has raised the emergent issue of biofouling, providing an explanation as to how shipowners and crew can benefit by reducing the risk of transferring alien aquatic species by way of the ship’s hull. “The introduction of invasive aquatic species (IAS) associated with global shipping has been identified as a significant threat to the world’s oceans and coastal ecosystems. Research suggests that 70-80% of IAS introductions occur through biofouling, and new areas are constantly being invaded.” Wangrau added: “Biofouling is undesirable accumulation of various aquatic organisms (microorganisms, plants, algae and animals) on submerged structures like ships’ hulls. This process can lead to the introduction of invasive aquatic species (IAS) into new environments.” Marine species establish a reproductive population in the host environment, becoming invasive, out-competing native species and multiplying into pest proportion. The problem has intensified over the last few decades due to increasing volume of traffic on our seas and represents a ACO Marine's new MARIPUR NF and CLARIMAR MF advanced wastewater management systems are the merchant, naval and megayacht sectors most effective solutions for meeting stringent IMO MEPC 227(64) rules. Compact and economical with the lowest operating costs of any sewage treatment plant, CLARIMAR MF and MARIPUR NF are proven to reduce coliform bacteria, TSS, COD, nitrogen and phosphorous content to levels significantly below the mandated requirements.

major threat to the world’s oceans and to the conservation of biodiversity. There are number of measures that shipowners can take to prevent or limit the scale of phenomenon, according to the UK P&I Club. These include: Keeping a biofouling record book, recording details of all inspections and biofouling management measures undertaken on the ship. It is recommended that it be retained on the ship for the life of the ship; An anti-fouling system should be used along with other innovative measures; Adopting biofouling resistant materials for piping and other unpainted components; A marine growth prevention systems (MGPSs) can be utilised for sea chests and internal seawater cooling systems; Crew members should administer regular in-water inspection; Training for ships’ masters and crews on in-water cleaning systems. Maintenance facility operators and those surveying or inspecting ships as appropriate should include instructions on the application of biofouling management and treatment procedures. “By taking these measures to prevent biofouling, the shipping industry can help preserve delicate marine eco-systems and benefit from improvements in the ship’s hydrodynamic performance. Reducing hull fouling decreases a ship’s resistance which in turn lowers fuel costs and emissions of air pollutants, making voyages more energy efficient, cost effective and less harmful to the environment,” said Wangrau. COATINGS ECOSPEED SOLVES A CRUISESHIP DILEMMA Subsea Industries’ Ecospeed coating is being presented as a cost-effective, environmentally-safe solution to the problems associated with maintaining cruiseship hulls in a pristine condition. Cruiseships, particularly when operating in warmer waters, can attract fouling organisms which create a bad impression – not only to passengers and prospective customers but to port operators. From the operator’s point of view, fouled hulls increase fuel consumption and thus costs. As hull coatings become worn and damaged, they attract still more fouling, leading to increased time spent in dry dock. Damaged and worn coatings leave hulls and underwater gear susceptible to corrosion, leading to further time spent in dry dock. Underwater cleaning will help preserve the appearance and performance of these high value ships, but with toxic anti-foulings and foul-release coatings an increasing number of ports will not permit such practices, as they lead to both increased toxins in the water and the risk of introduction of invasive non-native species. Ecospeed, however, offers a solution to these difficulties. It is durable, smooth, and, above all, non-toxic. Being ultra-strong it prevents corrosion and damage. As it is intended to remain in place rather than wear away, once applied it remains intact for many more years than anti-fouling or foul release coatings. Even underwater gear such as rudders and propellers can be protected – the Ecoshield variant is designed to minimise cavitation damage. If any touch-ups or repairs are needed, these are easily and quickly carried out during routine drydocking. Importantly, Ecospeed is easily cleaned, and being durable and non-toxic, underwater cleaning can be carried out anywhere with no risk of coating deterioration or increased release of toxins. In fact, the more Ecospeed is cleaned, the smoother it becomes, resulting in significant fuel savings. 11
