Zelim Unveils World’s First Unmanned Man Overboard Rescue Vessel at SMM Trade Fair

Zelim, the Edinburgh based sea survival innovator, has officially launched the world’s first unmanned/manned remotely controlled person-in-water rescue vessel.

GUARDIAN, an 8.4m long, 2.5 wide aluminium hulled Next Generation Fast Rescue Craft (FRC), was unveiled to the international maritime industry for the first time at the SMM Trade Fair, in Hamburg, Germany.

Specifically designed for rapid deployment from a ship to recover both conscious and unconscious man-overboard casualties, the GUARDIAN FRC can operate in maritime conditions that conventional manned recovery solutions would find challenging or too dangerous to deploy.

Taking four years’ research and development, with input from the UK’s Maritime & Coastguard Agency and the US Coastguard GUARDIAN incorporates Zelim’s type approved SWIFT rapid rescue conveyor and ZOE, Zelim’s intelligent detection software for optimising search.

During a MOB event, GUARDIAN is instantaneously lowered into the water by way of a ship’s existing LARS davit installed at deck level.  Once in the water, an Alamarin AJ285 waterjet powered by a single Bukh VGT 400HP motor speeds the rescue vessel along at a rate of 30-plus knots towards the casualty. GUARDIAN’S range is 15nmiles with a six-hour endurance.

As it nears the person(s) in the water, the FRC lowers the integrated SWIFT and slowly heads towards the casualty who is then recovered from the water by the rescue conveyor, which is specifically designed to grip and recover immersed casualties, whilst minimising the risk to casualties from the loss of hydrostatic pressure. SWIFT can pull two survivors to safety simultaneously, minimising the risk for rescuers.

Given that about 40% of all man-overboard incidents results in fatality, with more than 1000 people falling overboard annually, the efficiency and simplicity of Zelim’s GUARDIAN in rescue missions cannot be understated. 

“Sea survival is hugely dependent on the time it takes to retrieve individuals from the water, but inclement weather can prohibit the launch of manned rescue craft and lives are needlessly lost,” said Zelim founder and innovator Sam Mayall.

“Ship crews have little time to carry out an effective rescue before maritime conditions prevent the casualty from assisting in their own rescue. When rescue vessels approach, many survivors simply don’t have the strength to pull themselves to safety. This is even more difficult when they are unconscious or unresponsive. GUARDIAN has been designed to ensure more people can be rescued in the harshest of weather conditions.”

With capacity for 11 survivors (nine if GUARDIAN deployed with a two-person crew), the lightweight FRC also benefits from AI-based person-in-water detection and alerting system.

Peter Lloyd, Zelim’s Director of Search and Rescue, said: “Speed is the key to rescuing individuals from the water before they perish. But first you must find your casualty. Sea search is notoriously difficult with human performance subject to distraction and loss of attention, especially during a prolonged search. In Zelim’s aim to develop an unmanned rescue vessel, sea search had to be automated.”

The result of Zelim’s product development was ZOE, a new software tool capable of providing instant detection and alerting of persons and objects that enter a field of view. ZOE is also capable of differentiating between a human in the water and other objects that might be present such as buoys, flotsam and jetsam.

Providing real time location information and integrated with the GUARDIAN’S navigational system, the technology allows rescuers to see what the human eye cannot with visual cues overlayed on a simple display.

While Zelim is marketing SWIFT and ZOE as standalone maritime safety and security tools, their integration with GUARDIAN demonstrates how easily the technology can mitigate the risks for both rescuer and casualty to improve the chances of MOB recovery.

The decision to launch any rescue asset is always a balance between the risk to the rescuers and the probability of success. An unmanned, or lean manned GUARDIAN, may permit a launch in conditions beyond those normally accepted,” said Lloyd.

The FRC can operate with or without a crew, remotely, and has enhanced rescue situational awareness capability. It has the same footprint as conventional craft, and can be easily stowed and deployed using existing davits.

In addition to MOB missions, GUARDIAN can perform a variety unmanned maritime safety and security roles, including search and rescue, security patrols, standby and recovery. Zelim believes GUARDIAN should be installed on ocean-going vessels, including cruise ships, and offshore vessels and platforms, as a matter of course.

Zelim’s SWIFT recovery system receives Lloyd’s Register approval

Zelim’s SWIFT device approved for maritime use

Zelim’s SWIFT man overboard recovery system has received type approval from Lloyd’s Register.

This certification follows extensive in-water tests at Fleetwood Testing Laboratory and Heavy Weather Sea Trials, enabling the system’s widespread adoption within the maritime industry.

The SWIFT system was successfully demonstrated during trials in May 2023 at a windfarm offshore Ramsgate in the Southern Bight of the North Sea.

The system recovered a test dummy two nautical miles offshore, performing more than twenty times faster than conventional man overboard equipment.

The SWIFT device is designed to pull both conscious and unconscious individuals from the sea in under one minute.

Compliance with SOLAS standards

The SWIFT system has been confirmed as compliant with the International Convention for the Safety of Life at Sea (SOLAS) standards.

Zelim’s CEO, Sam Mayall, highlighted the significance of this certification for the global maritime and offshore industries, stating: “Type approval certification assures the global maritime and offshore industries that SWIFT is compliant with SOLAS and can be adopted as a primary means of man overboard recovery for ships and offshore installations.”

Developed by operational search and rescue personnel, the SWIFT system uses a conveyor belt mechanism attached to a rescue vessel.

When the vessel approaches a casualty, the system lowers into the water, and the conveyor belt pulls the individual to safety.

Improving survival rates at sea

Mayall emphasised the importance of reducing the time it takes to retrieve individuals from the water: “Sea survival is hugely dependent on the time it takes to retrieve individuals from the water, but often high sea states make recovery difficult.

“When rescue vessels approach, many survivors do not have the strength to pull themselves to safety.”

Industry statistics underscore the urgency of improved man overboard recovery methods.

Only 17% to 25% of passengers who fall overboard during cruises survive.

Additionally, between 2015 and 2023, 40% of the 308 man overboard incidents reported to the UK’s Marine Accident Investigation Board resulted in fatalities.

Potential impact on maritime safety

Zelim’s Chief Operating Officer, Stewart Gregory, stressed the potential impact of the SWIFT system on reducing fatalities: “The maritime and offshore industries now have a fully type approved certified system capable of rapidly rescuing people from the sea in all weather conditions.

“Lives lost to man overboard incidents could be reduced substantially if every rescue boat, crew boat, pilot boat or tender was equipped with SWIFT as a matter of course.”

Swift man overboard recovery system achieves Lloyd’s Register type approval: summary

Zelim’s SWIFT man overboard recovery system has received full type approval from Lloyd’s Register, following rigorous performance tests.

This certification ensures that the SWIFT system is compliant with SOLAS standards and ready for widespread adoption in the maritime industry.

Designed to rapidly pull individuals from the sea, the SWIFT system demonstrated its efficiency by outperforming traditional rescue methods during trials.

Aim the nozzle or hose at the base of the fire. 

Focusing on the base, where the fuel source is, helps to extinguish the flames more effectively.

Squeeze the Handle

Squeeze the handle or lever slowly and evenly. 

This releases the extinguishing agent. 

Make sure to control the discharge by applying steady pressure.

Sweep Side to Side

Sweep the nozzle or hose from side to side at the base of the fire. 

Continue this motion until the fire is completely out. 

Be thorough and ensure the fire doesn’t reignite.

Safety Precautions

  • Stay Alert: Always keep an eye on the fire, even after it seems to be extinguished.
  • Maintain Distance: Stand at a safe distance from the fire, typically about 8-10 feet, and move closer as the fire diminishes.
  • Know When to Evacuate: If the fire becomes uncontrollable or spreads rapidly, evacuate immediately and call emergency services.

What are the Main Causes of Electrical Fires?

electrical fire causes

Electrical fires are a common and dangerous type of household fire. 

Understanding their causes can help in preventing them.

Faulty Wiring

Old, damaged, or improperly installed wiring is a leading cause of electrical fires. 

Over time, wires can degrade, leading to exposed or frayed wires that can spark and ignite surrounding materials. 

Additionally, amateur electrical work can create unsafe conditions that may result in fires.

Overloaded Circuits

Plugging too many devices into a single outlet or power strip can overload circuits. 

This overload causes excessive heat, which can melt the wiring and start a fire. 

Using high-wattage appliances on circuits not designed to handle them is particularly risky.

Faulty Appliances

Defective or poorly maintained appliances can also spark electrical fires. 

Appliances with damaged cords or internal electrical faults can overheat and ignite. 

Regular maintenance and prompt repairs are essential to keep appliances safe.

Extension Cords

Improper use of extension cords is another common cause. 

Extension cords can overheat if used to power high-wattage appliances or if they are used for long periods. 

Running extension cords under carpets or through doorways can damage them, increasing the fire risk.

Space Heaters

Space heaters are often used to provide additional warmth but can be dangerous if not used correctly. 

Placing them too close to flammable materials or leaving them unattended can cause fires. 

Heaters with faulty thermostats or those left on for too long are particularly hazardous.

Light Fixtures

Using incorrect bulb wattage in light fixtures can lead to overheating. 

Exceeding the recommended wattage can cause the light fixture to overheat, melt, and potentially ignite surrounding materials. 

Ensure all bulbs match the recommended wattage for your fixtures.

Electrical Outlets

Loose or worn-out electrical outlets can cause arcing, where electricity jumps from one connection to another. 

This arcing can generate heat and ignite nearby materials. 

Ensuring outlets are securely fitted and in good condition helps prevent this risk.

What to do if There is an Electrical Fire?

electrical fire what to do

If there is an electrical fire, use these steps to stay as safe as possible: 

Stay Calm and Assess the Situation

If an electrical fire starts, staying calm is crucial. 

Panicking can lead to mistakes and make the situation worse. 

Quickly assess the severity of the fire. If it is small and manageable, you might be able to extinguish it safely.

Disconnect Power

If it is safe to do so, disconnect the power source to the electrical device causing the fire. 

This can often be done by unplugging the device or turning off the power at the circuit breaker. 

Cutting off the power source can help stop the fire from spreading.

Use the Right Extinguisher

Use a Dry Powder or CO2 fire extinguisher, which is designed for electrical fires. 

Remember to use the PASS technique: Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side.

Evacuate if Necessary

If the fire is too large or out of control, evacuate immediately. 

Do not try to extinguish a fire that is spreading rapidly or producing a lot of smoke. 

Make sure everyone in the building is aware of the fire and evacuates safely. 

Close doors behind you as you leave to help contain the fire.

Call Emergency Services

Once you are safely outside, call the emergency services number. 

Provide the dispatcher with your location and details about the fire. 

Do not assume someone else has already called. 

Emergency responders have the equipment and expertise to handle electrical fires safely.

Do Not Use Water

Never use water to extinguish an electrical fire. 

Water conducts electricity, which can cause electric shock and make the fire worse. 

It is essential to use only the appropriate fire extinguishers.

Wait for Professionals

Wait for the fire department to handle the situation. 

They have the necessary training and equipment to extinguish electrical fires safely and prevent them from reigniting.

Conclusion

Electrical fires can be dangerous, but knowing how to prevent and respond to them can save lives and property. 

Use CO2 extinguishers for electrical fires and follow the PASS technique for effective use. 

Regularly inspect your home for potential fire hazards, maintain electrical equipment, and never use water on an electrical fire. 

By staying informed and prepared, you can protect your home and loved ones from the dangers of electrical fires.

Bright days ahead for container shipping safety

Consilium Safety Group discusses the integration of digital and AI-driven solutions in container shipping safety, introducing the revolutionary TMS

Almost every shirt we wear, and every gadget we use has made a journey across the seas, a testament to the container shipping industry’s role in knitting the global economy together.

These colourful containers move more than 90 per cent of global trade.

Capable of carrying over 24,000 containers, today´s ships carry an incredible 1 500 percent more containers than in the late 1960s.

Yet, as these ships swell in size, now stretching to the lengths of four football fields, they carry not just cargo but a potential risk of fire.

A peril that grows with every container added to their load.

Thobias Ernfridsson, the Chief Technology Officer at Consilium Safety Group, sits at the heart of efforts to mitigate this risk.

“The expansion of container transportation is undeniable,” he states, “and with it, the risk of fire escalates, posing a significant threat to goods, ships, and more importantly, human lives and the environment.”

A stark reality

This recognition is echoed in the stark figures of the 2023 Cargosafe study, commissioned by the European Maritime Safety Agency (EMSA), which highlights the potential risk associated with the median operation of these ships.

The study shows a ship faces potential losses including fatalities, cargo, the ship itself, environmental damage, and salvage costs.

As insurance premiums for container shipping rise by 55 per cent, reflecting the increased risks of fire and cargo loss, the industry is at a crossroads.

“With the values aboard these vessels soaring, insurance costs can account for the third highest operational expense, after fuel and crew,” Ernfridsson explains.

Yet, amidst the calculus of risk and premium, Ernfridsson sees a silver lining: “Cut through the risk, and you slice through the premiums. It’s straightforward economics but underpinned by a complex challenge.”

Innovation at the helm

In the wake of disaster, innovation often follows, spurred by necessity and the collective will for change.

“Accidents are never good, but it is usually the way that triggers a desire for change”, says Ernfridsson.

 This sentiment is echoed across the industry, from insurance companies and ship owners to ports and suppliers, all recognizing the need for a more digital and AI-driven approach to early detection and fire prevention.

The International Maritime Organization (IMO) has responded with plans to introduce new fire safety regulations by January 2028.

Aiming to address the increased fire risks brought on by container ships and the misdeclaration of hazardous goods.

“My understanding is that IMO’s wish or requirement is that safety players like Consilium should embrace digitalisation a bit more on board,” says Ernfridsson.

The revolutionary TMS technology

At the heart of Consilium Safety Group’s response to this call is the strategic acquisition of Radicos, a vanguard in linear heat detection.

The acquisition has birthed the innovation of a Temperature Monitoring System (TMS), a product formerly under Radicos before its rebranding and integration into Consilium’s fire, flame, and gas safety solutions.

TMS represents a fundamental shift in how fire safety is approached at sea.

Leveraging a sophisticated network of sensors to monitor for the slightest anomalies in temperature that could indicate a possible fire.

Promises early detection of fire risks, potentially saving lives, cargo, and ships from disaster.

“This solution allows quick tracing if for instance, one container is at 18 degrees Celsius, and the adjacent one is 35 degrees Celsius.

“Using our safety management system software, SMiG, operators receive valuable information when a conflicting pattern is identified.

“With this solution, incidents are detected in an early stage, even at ambient temperatures.

It’s a true game-changer for safety within the container shipping industry”, highlights Thobias Ernfridsson.

The robustness of the system is further underlined by real-world testing.

It has been rigorously tested in harsh environments, including various stressors such as saltwater exposure, vibrations, wind and temperature variations.

The technology has proven to be highly reliable and effective in the most demanding maritime conditions.

With a new round of real-world trials planned for early 2025, and the first ship deliveries and installations expected later that summer, the anticipation within the marine community is palpable.

“It is in everyone’s interest to bring this product to market as quickly as possible.

“We have listened to our customers, insurers, and the authorities.

“Based on this, we have developed this outstanding product,” says Ernfridsson, reflecting a sentiment that goes beyond commercial interests and touches on collective responsibility for safety at sea.

“Simply said, there won’t be as many fires, everyone will be happy”, he concludes.

The expansive potential of TMS

The potential applications for TMS extend far beyond container ships, with interest from sectors ranging from car carriers such as RoRo ships to agriculture.

 “This technology is unique,” says Marcus Andersson, CCO at Consilium, “and its ability to monitor temperature changes has a wide range of applications, from detecting heat increases in cars on a car deck to monitoring the well-being of livestock.”

He explains:  “It was our customers who led us to expand our vision,” Andersson reveals, his voice a testament to the collaborative spirit that drives this innovation.

“They nudged us to see beyond the immediate. And now, car carriers are on the horizon.

“It´s not every day you hear enthusiasm for monitoring heat variations below cars at a car deck, but here we are, in dialogue with shipping companies”.

Our conversation takes an unexpected detour through the countryside, to a chicken farm, where the potential of TMS to save lives takes on another dimension.

“Imagine hanging a cable, a simple act, and suddenly you’re not just monitoring chickens, you’re actively protecting them.

“The rollout of TMS will be methodical, phased, and sensitive to the ecosystems it enters.

“We start with containers and car carriers, yes, but it’s about the order of things,” Andersson explains.

“The fire alarm, the gas alarm, and then this – our solution.

“It’s a sequence designed not just for implementation, but for integration, to become a support system that is as seamless as it is essential”.

Talking to Marcus Andersson, the essence of TMS as more than just a product but a solution comes to the fore.

It’s a technology born from the need to solve a critical problem that expands its embrace to offer protection and peace of mind.

“We can act as a supplier with support. We want to be close to our customers, to meet their challenges, which is why this was created,” he says, summing up the essence of their mission.

 ”We’re not just engineers and salespeople, we’re partners in safety, wherever that journey might lead us”, Andersson concludes.

TMS technology in brief

Basic concept

Imagine the TMS as a highly sensitive digital thermometer spread throughout a ship, constantly checking the temperature of every container on board.

This system is like a network of watchful eyes, designed to notice even the smallest rise in temperature that could indicate a fire risk.

How it works

The system uses a series of advanced sensors placed around the ship in direct proximity of the containers.

These sensors continuously monitor temperatures and send this data to a central system that execute advanced energy flow analysis onboard the ship.

It’s akin to having a network of smoke detectors, but instead of detecting smoke, they’re looking for unusual heat.

Detection and response

Should one container get warmer than usual, perhaps due to a malfunctioning electronic device, a battery or a chemical reaction, the TMS quickly spots this temperature anomaly.

The system then alerts the ship’s crew to the exact location of the potential hazard, allowing them to take immediate action, such as investigating the issue or initiating firefighting measures, long before a small problem turns into a major fire.

Integration with existing systems

TMS isn’t a standalone service; it’s integrated with the ship’s overall safety management system.

This means it works in harmony with other safety measures onboard, like fire extinguishers and alarms, to provide a comprehensive safety net.

Benefits beyond early detection

The true game-changer of this system lies not just in detecting potential fires but in its ability to provide peace of mind.

For ship operators, it means reducing the risk of losing cargo or, more importantly, risking lives.

For insurance companies, it’s about lowering the chances of costly disasters.

And for the global economy, it ensures that the goods we rely on every day make it safely across the seas.

Queensland underground coal mine fire continues for five days

Fire at Grosvenor Coal Mine in Queensland

Queensland’s largest underground coal mine, Grosvenor Coal Mine, has been burning for five days, as reported by ABC News Australia.

The fire, ignited by a spark that triggered methane gas, forced the safe evacuation of workers on Saturday morning.

The mine, located near Moranbah in Central Queensland, employs approximately 1,400 people.

Efforts to control the fire involve sealing the mine to cut off oxygen.

Remote control bulldozers are pushing dirt towards the shafts, as it is too dangerous for humans to be present.

The fire, burning up to half a kilometre underground, is fuelled by methane gas and coal.

This incident follows a 2020 explosion at the same mine that injured five workers and led to its closure until February 2022.

Sealing operations and technology

The sealing process is critical to extinguishing the fire, according to ABC News Australia.

Three remote-controlled bulldozers are currently assisting in sealing the mine shafts with dirt and rocks.

Anglo American, the mine’s owner, emphasised the importance of remote control technology in their response.

Industrial-level expanding foam and a steel plate covered with dirt are used to form a plug in the shaft.

Additionally, a GAG unit, a 12-metre-long apparatus mounted on a truck, is pumping carbon dioxide, nitrogen, and water vapour into the mine to reduce oxygen levels.

GAG stands for Górniczy Agregat Gaśniczy, a Polish term meaning “mine fire suppression apparatus”.

This equipment is vital in managing the fire without human presence in hazardous areas.

Safety and historical context

Queensland has a history of coal mine fires leading to fatalities. In 1975, an explosion at the Kianga No. 1 mine killed 13 men.

The Box Flat Mine fire in Ipswich in 1972 resulted in 17 deaths, with three more fatalities during sealing attempts.

These tragedies led to advancements in safety and gas detection systems.

Stephen Smyth from the Mining and Energy Union expressed confidence in the current re-sealing plan, citing the expertise of the personnel involved: “There’s no doubt some of the best-trained people in the world are on site”.

The recent experience with similar incidents at North Goonyella in 2018 and Grosvenor in 2020 has prepared the team for this challenge.

Air quality monitoring and community impact

Anglo American reported that sealing efforts have significantly reduced the amount of oxygen available to the underground fire.

The QMRS mobile extinguisher unit (GAG) continues to aid in this effort, with a noticeable reduction in smoke levels.

Air quality monitoring around Moranbah, a town with a population of about 9,500, indicates that all readings are within acceptable limits.

“All monitors are reporting readings within acceptable limits, indicating no impact on community health from smoke or airborne contaminants,” the company stated.

Fire safety issues persist in European ship inspections despite lower detention rates

Report highlights ongoing fire safety issues

The proportion of ships detained after inspections by European port authorities fell from a 10-year high in 2023 but familiar failings continued, according to a new report.

Fire safety, electrical issues and seafarer welfare remained among the top reasons for detaining ships by the 27 states that are part of the Paris MoU agreement, as reported by Trade Winds.

The detention rate of ships inspected in 2023 was 3.81%, down from 4.25% the previous year.

However, it was still above the pre-COVID-19 rates in 2019 when it dipped below 3%.

Performance of ship flags

The four lowest-ranked flags all performed worse in 2023 compared to the previous year.

The highest number of detentions per inspection was recorded by Cameroon (35%), followed by Tanzania (34%), Comoros (22%), and Vanuatu (18%).

A higher proportion of livestock carriers and general cargo ships were detained than other ship types.

In 2022, Moldova-flagged vessels had the highest proportion of detentions, with 31% of inspected ships being detained.

Criticism of maritime sector players

The Paris MoU leadership in last year’s report criticised shipowners, flag states, and recognised organisations for not doing enough to ensure good quality shipping.

The report noted the “minimal improvement” in 2023 and stated that it would continue to monitor developments closely this year.

It emphasised the expectation for all players in the maritime sector to “take the measures necessary to guarantee safe and environment-friendly shipping, with adequate working and living conditions on board”.

Background on the Paris MoU

The Paris MoU is one of 10 port state control regimes worldwide.

Its membership includes 26 European coastal states and Canada.

The organisation focuses on the safety and environmental standards of ships to ensure they meet international regulations.
