Gizat rolls out air purification solution to maritime market

The data-driven air quality platform, Aura. The data-driven air quality platform, Aura.

Gizat Global Communication has signed an agreement with Aura Air to bring an innovative smart air purity solution to the maritime market in a bid to tackle pollution and the spread of bacteria onboard ships. The solution has proven a 99.9 per cent effectiveness against COVID -19.

The smart air purity platform, known as Aura, was developed by Aura Air. The collaboration will see the solution rolled out across commercial vessels and cruise ships in crew and passenger rooms to help purify air. The physical and mental wellbeing of onboard crew and passengers can be severely affected by poor air quality and studies have found that lower quality air can lead to poor cognitive abilities and depression.

With the current COVID-19 situation, there is a need not only to enhance crew safety and welfare but to do so in a smart way. The Aura system can change its operations based on everchanging environmental factors and can be monitored both from the vessel and from the HQ. The data-driven air quality platform is based on a user behaviour algorithm and has the ability to be integrated with other IoT devices onboard.

Aura filters and disinfects air through 4 unique stages. 

Through 4 steps the smart air quality platform detects poor air quality and recommends how it can be improved.

Step 1 – Detection. Aura detects indoor and outdoor air quality via real-time monitoring through an array of smart sensors. Substances such as nitrogen oxides (NOx), volatile organic compounds (VOCs), particulate matter, and many more pollutants are detected.

Step 2 - User personalisation. In the second step, the unique air quality assistant Heidy personalises the Aura device precisely to meet an individual’s needs and health necessities. After completing the Heidy questionnaire, the Aura device provides relevant recommendations, customising the device based on the individual’s personal profile.

Step 3 - Filter and disinfection. Aura filters and disinfects air through four stages. A pre-filter eliminates large particles of dust, pollen, insects, animal hair and other large particles first. The patented Ray filter filters filters 99.98 per cent of microns up to 0.3 microns. The carbon layer absorbs VOCs and bad odours, while the smart copper fabric filters viruses, bacteria, and more. The Sterionizer is a component based on the technology of bipolar ionization and generates positive and negative ions that purify and freshen indoor air by eliminating the harmful pollutants. UVC LEDs are used to effectively neutralise bacteria, viruses, and parasites by destroying the proteins on the cell membrane.

Step 4 - Data and real-time control. The air quality data is monitored in real-time to provide smart insights and customised recommendations. Energy efficiency is enhanced by the distribution of fresh air according to CO2 real-time measurements. Based on the data, the air conditioning can be adjusted according to the presence of people in the room.

Gizat confirmed to Digital Ship that the company has now started offering the solution to its maritime partners, and so far, the feedback has been positive.

COVID-19 and Aura

Recently, the Diamond Princess cruise ship experienced a severe infection of the Coronavirus as it passed through the air conditioning system. According to The Centre for Evidence-Based Medicine[1] there were 454 confirmed cases of Coronavirus onboard. Among the 3,711 passengers and crew onboard, there were 621 (17 per cent) symptomatic and asymptomatic people with positive COVID-19 tests. Preventing the spread of such a virus is vital to the wellbeing of the cruise line’s staff and passengers.

According to Gizat, the development of Aura came as a request from the SHIBA medical centre. The centre wanted a device to purify air from all kinds of bacteria and polluted hazards in hospital facilities. Since the COVID-19 outbreak in 2020, demand for the system to purify air from the virus increased.

In August 2019, Aura Smart Air performed a trial in collaboration with The Department of General and Oncological Surgery at The Chaim Sheba Medical Centre in the implementation of air purifiers for the purpose of disinfecting and purifying the air from various pollutants.

According to a white paper published in July 2020, initial results showed significant ability for Aura to capture various bacteria. Gizat therefore decided to use its previous experimental results obtained in collaboration with Aura Smart Air, to obtain a Coronavirus and built a model to test devices for their ability to filter or eliminate the virus.

In May 2020, the company began a clinical experiment to test the effectiveness of Aura Air’s disinfection capabilities on the Coronavirus as part of its strategic, long-term collaboration. The aim of the trial was to quantify the properties of the Aura Smart Air device to purify air contaminated by a Coronavirus similar in size with the SARS-CoV_2.

These early but promising results provide the basis for more advanced experiments studying the performance of the Aura Smart Air device in closed spaces.

    The International Transport Workers’ Federation (ITF) has issued a stark warning that if temporary short cuts adopted in the industry during the COVID-19 pandemic continue or become permanent, then there will be a rise in shipping accidents and environmental disasters.

  • A giant leap forward for maritime IoT

    Author: Andrew Loretta, director, maritime business development for ORBCOMM.

    We are proud to be a part of the recently announced partnership with AAC Clyde Space AB and SAAB AB that is ushering in a new era in maritime communications through the development of the next generation of a space-based very high frequency (VHF) Data Exchange System (VDES). As the maritime industry embraces digitalisation, we expect a greater emphasis on secure data exchange and ship to shore communication—and we look forward to facilitating this shift in operations through our technology in conjunction with our partners.

    As long-term providers of automatic identification system (AIS) solutions and a touchpoint for space-based maritime data, we at ORBCOMM relish the opportunity to demonstrate the benefits that the significantly increased bandwidth that VDES will offer not just our maritime customers but the supply chain as a whole.

    With up to 32 times more bandwidth than currently offered by AIS and two-way communication, the ground-breaking new system is the next natural step for satellite technology and will allow users to completely rethink the way they manage their fleets. VDES bridges the gap between ship and shore in a way that the industry has been crying out for.

    One of the changes we are most excited about is how innovators now have an open playing field to craft interesting technical solutions specifically for the maritime world without having to scale back their imaginations to match the limited accessibility. The sky is literally the limit once these new satellites come into play and we are keen to work with newcomers and support existing companies with bringing their visions to life so that they can propel this industry forward.

    We have already seen how our AIS data is used not just for real-time vessel and asset tracking, but also as a base line from which interesting insights can be drawn about the global fleet. A good example is a recent article by maritime expert and Navigate PR director Bill Lines, who used our partner Marine Traffic’s data in conjunction with information from the Baltic Exchange to create a snapshot of tanker operating expenses.  

    We already know that VDES can be integrated with existing vessel systems and we are keen to see how ship operators, managers and equipment manufacturers will use this data highways to improve navigation, boost safety, enforce regulations, reduce emissions via fuel consumption, and improve on-board decision making by delivering data-driven insight.

    Work on the project begins next month when AAC Clyde Space will begin manufacturing the satellite that will boast a VDES payload from Saab. We expect to complete the in-orbit VDES capability demonstration of the first EPIC 3U satellite in the first quarter 2023 and are happy to say that ORBCOMM customers can expect to receive AIS data from the new satellite and so will benefit from the project as it comes on line.

    As a larger constellation of VDES satellites is contemplated, we look forward to being the conduit for better-quality data in larger quantities. Our considerable IoT experience puts us in a prime position to reap the benefits of the technology as it evolves, and we are excited to work with our partners and guide them on the best path to maximize the benefits of using VDES technology.

    To learn more about the project, we encourage you to watch this video, which features Greg Flessate, ORBCOMM senior vice president and general manager for Government, AIS and Business Operations, as well as AAC Clyde Space chief executive officer Luis Gomes and Saab’s Christer Fuglesang being interviewed by Rachel Carroll, president and managing partner at Edison.

  • Connectivity demand booms as leisure vessels become safer, reports IEC Telecom

    Demand for faster and cheaper connectivity at sea is set to increase as sailing is recognised as a safer place to work, travel and holiday during the COVID-19 pandemic says satcom specialist IEC Telecom, which is experiencing an increase in enquiries from vessel operators in the maritime leisure sector.

    With ‘lockdowns’ and restrictions easing in some parts of the world, yacht owners are now able to enjoy ‘social distancing’ onboard their vessels, which is leading to a boost in demand for high-speed connectivity and increased bandwidth capacity. With the focus on social distancing, yachts are becoming increasingly attractive remote offices for those able to attend to business matters while enjoying the open sea, sunshine and fresh air. During this challenging time, sailors have an increased need to stay connected for both personal and operational purposes as well as to avoid the need to go ashore as much as possible.

    The signs are pointing to an upsurge in leisure boating. Yacht chartering is seen as one of the safest ways to enjoy a break at present due to the minimal contact charterers have with other people. Yachts are considered to be more hygienic, given the ratio of crew to guests and the exclusivity of being on a private boat. Affluent consumers are looking for getaways with fewer crowds, more privacy and the ability to gather privately with those closest to them. The Boat Affair platform (whose rentals are available in more than 60 countries) has seen a 23 per cent increase in requests from customers who traditionally would opt for a hotel vacation or a seaside resort but are now seeking a safer alternative. And, according to a new survey by LuggageHero, 25 per cent of travellers report they will try to avoid crowded commercial flights and public transportation in a post-coronavirus world.

    Meanwhile, in countries where travel is still restricted, many larger leisure boats and super yachts remain fully crewed and operational – also leading to increased need for connectivity as crews try to stay in touch with family and friends while conducting as many ship operations as possible via remote techniques. With crew restricted to remaining on the vessel in many places, higher speeds and larger bandwidth capacity is needed to provide leisure activities too.

    The leisure boat sector was initially hit hard by international lockdowns and is now incurring additional costs for deep cleaning, personal protective equipment, virus testing etc which are not generally reflected in the charter fees. As a result, systems which allow to optimise bandwidth consumption in order to reduce expenses on communication are proving popular with consumers looking to install or upgrade yacht connectivity systems.

    Gwenael Loheac, chief executive officer Western & Southern Europe for IEC Telecom said: “Data traffic on leisure vessels has increased during this crisis period because crew, vessel operators and passengers need to exchange information on a more regular basis. In response to COVID-19, we are seeing increased demand for flexible tariffs to enable leisure vessel operators to adapt quickly to fluctuating connectivity requirements. Fortunately, we are well-placed to meet these needs, having a wide portfolio of solutions designed to provide best user experience, while keeping communications costs at bay.

    IEC Telecom recently launched OneGate Marine Compact, a new lightweight digital solution with a network management system which provides full visibility over on-board network assets (both satellite and GSM) and enables vessel owners to control expenses and optimise consumption via a digital dashboard.

    Mr Loheac commented: “OneGate Marine Compact was developed to cater to all major requirements of the leisure boat sector – addressing their needs for speed, bandwidth and cost optimisation. OneGate Marine Compact is an agile, lightweight, highly-adaptable and easy-to-install digital communications system which gives complete access to the benefits of digital connectivity even on smaller vessels. At this challenging time this system is providing many of the answers yacht owners need to enable them to conduct online business and leisure activities safely and securely.”
