Sanitation is an essential component of cruise ship operation, and in recent months it has become an even more critical component. Global port authorities around the world are carefully screening for COVID-19 coronavirus along with other illnesses such as the common flu, all of which could lead to delays or denial of permission for ships to enter ports. 

This new health challenge calls for new sanitation solutions. Cruise ships usually use heavy-duty chemical disinfectants, but there is a better and safer way. Electrolyzed water - also known as hypochlorous acid (HOCl) - is a highly effective and intrinsically safe sanitizing agent, and it can be generated in unlimited quantities with technology from Miami-based manufacturer EcoloxTech. 

The single most important feature of hypochlorous acid is that it is unusually efficient in eliminating viruses. "One of the big reasons why people are switching over is efficacy. Working with Norwegian Cruise Line, we did research at a FDA-approved lab proving that electrolytically generated hypochlorous acid can kill norovirus in less than one minute at 50 ppm. Given that norovirus is listed by the CDC as one of the top five foodborne pathogens, this has huge implications not just for general sanitation but also for food sanitation and food contact surface sanitation,” says Morten Larsen, CEO of EcoloxTech. 

National and international reference laboratories have proven that HOCl works very well against viruses, including norovirus and human coronaviruses. One study is of particular interest: in 2016, researchers at the University of Washington School of Public Health found that HOCl was more than 99.999 percent effective in eliminating coronavirus OC43, which is similar to COVID-19.

A proven solution for cruise ships

HOCl technology is already in use aboard ships in Norwegian Cruise Line Holdings’ fleet. "We use EcoloxTech's hypochlorous acid system on board because of its proven effectiveness in killing bacteria, fungi and viruses,” says Robert Wilkinson, Senior Director of Environmental Health and Occupational Safety for Norwegian Cruise Line Holdings. "It reduces our dependence on the usual harsh chemicals and provides and additional layer of safety for our crewmembers and guests. Our shipboard teams truly appreciate the deployment of this new technology.” 

Wilkinson notes that HOCl is the rare single product that can be used to disinfect every compartment onboard, from galleys and dining areas to cabins. HOCl that is generated from EcoloxTech systems is FDA-cleared for washing fish and seafood, fruits and vegetables and sanitation of food prep surfaces without rinsing - making it a perfect choice for the galley. EcoloxTech is the only company that has obtained this clearance from the FDA in the form of a food contact notification (FCN 1811). It is also listed by the USDA as an authorized material for use in organic food production. 

For large-scale disinfection, HOCl can be dispensed using a fogger without any chemical-related PPE for workers. HOCl is intrinsically safe, as it is non-irritant and the human body produces the same molecule for self-defense. In fact, it is so safe to inhale that it is being evaluated as a treatment for throat and lung infections. By contrast, the preparatory steps required for other fogging agents of similar power - products based on peracetic acid, ozone, chlorine dioxide or peroxides - require considerable time and expense. 

In hotel areas of the ship, HOCl has an extra edge over bleach and peroxide-based chemicals because it will not cause discoloration of most carpets, furniture and textiles. This is a critical economic and operational consideration when disinfecting hundreds of cabins. 

The EcoloxTech system is available in multiple sizes, and custom units can be configured to fit into available space on board

The largest EcoloxTech installations can produce gallons of sanitizing solution every minute

For smaller spaces and applications, EcoloxTech's compact wall-mounted unit is self-contained and easy to install

With modern technology, HOCl can be generated in unlimited quantities using only electricity, table salt and water, and EcoloxTech makes equipment for customers to do it themselves. EcoloxTech offers hypochlorous acid-generating units in sizes and formats for all applications, from home use up to the largest shipboard applications.  

With unlimited on-board HOCl generation, there is no need to resupply the ship with toxic cleaning products. This reduces the ship's supply chain costs and the need to carry toxic chemicals on board and is an effective and practical solution to a mission-critical challenge. 

With better efficacy and safety, unlimited capacity and ship-wide usability, hypochlorous acid is a superior solution for disinfection. For more information on the benefits of EcoloxTech products and electrolyzed water, visit www.ecoloxtech.com.

Failure to follow COLREGS and fatigue caused a collision between a cargo ship and a fishing boat northeast of Tauranga, New Zealand in July last year, an investigation into the accident has determined. The Transport Accident Investigation Commission’s (TAIC) investigation shows the collision involving containership Kota Lembah and fishing vessel Commission could have been avoided by following established procedures and ensuring that crews do not work for long hours without rest. TAIC concluded that the boxship was the give-way vessel, but did not and could not take the correct action...

With efforts accelerating to develop offshore wind farms, there remain many unresolved questions on the scope of U.S. cabotage laws and how specifically the Jones Act will be applied to the construction of the wind farms. While the U.S. has said that it will apply the regulations in a similar fashion to their previous applications to the offshore oil and gas industry, partners at the law firm of Winston & Strawn highlight that because of a jurisdictional ambiguity, which was...

For the second time in weeks, Brazilian drug smugglers posing as cruise passengers were arrested while attempting to transport cocaine between Brazil and Europe. The latest group was intercepted boarding a cruise ship departing for a transatlantic cruise while the prior group was intercepted in Spain after having completed the crossing from Brazil. Brazil’s Polícia Federal announced the arrests which happened on April 18 reporting that six people were detained after attempting to board Costa’s Costa Diadema in the port...

Danish offshore wind farm developer Ørsted has delivered the first power from Taiwan’s largest offshore wind project, a development that marks another milestone in the company’s offshore wind power ambitions. Ørsted announced it has successfully delivered first power from the Greater Changhua 1 & 2a offshore wind farm, Taiwan’s largest offshore wind project and the company’s first large-scale project in the Asia-Pacific region. Located 35-60 kilometers off Taiwan’s west coast, the wind farm has a total capacity of 900 MW. Once completed this year, the wind...
