The maritime industry has always dealt with critical situations and has been facing many challenges operating in harsh marine environments throughout the years. The maritime operation is colossal, expensive, and involved in many complications. While it supports a major portion of global trading and shipping, it also entails many unforeseen crises and immense risks. Such crises and risks not only affect the maritime companies and the people directly involved in the operation but also influences the global economy substantially.
A number of seafarers lose their lives every year due to ship collisions, fires, drowning, pirates attacks, and other accidents. Critical weather conditions and lack of control over the huge off-shore perimeter are some of the reasons behind these crises.
Some of the major Maritime crises in the last 30 days –
How Applications by Upteko can prevent these Maritime Challenges.
Upteko has developed a multi-purpose end-to-end automated drone system that can be used to control and solve critical maritime challenges and in some cases prevent the crises in the first place.
Fire Hazard Inspection.
Current procedures for preventing ship fires include extinguishers, rules forbidding smoking onboard, and visual inspection. Crews need to patrol and check for a smoke every 30 minutes in all ship areas. This method is not accurate at detecting container fires, and even when detected, important time is spent on finding where the fire originated from.
Statistics show a fire takes place on a ship every 60 days, and this has increased to every 30 days in recent years.
Upteko has created beacons for the drone to position itself over the ship during situational awareness and docking. With the push of more beacons for larger ships and one beacon for smaller ships, the drone will position itself over the beacon and use the thermal sensor to make a heat map of the ship. If any abnormal heat signatures are present, the system will give an alarm to the bridge, that an area is hotter than what it is normally. It is then possible to see on the live heatmap, where the heat is located so an inspection can be made in the correct area.
The Docking Application
Ship docking is done with assistance from either the captain's assistant or a local port pilot. It can often be done with the use of tugboats and ropes and would take up to 1-2 hours for larger ships. in some cases, other ships have been landed and the docking situation has changed drastically in the port, and assessment from the ground does not provide sufficient overview to avoid collisions. The lack of aerial overview is a problem for large ships in busy ports. Any contact between the ship and other objects can result in hull damage, damage to already docked ships, and man overboard situations which as stated above, is hard to detect and costly to fix. Whilst this is a problem for the ship itself, there is an added risk of damaging third-party property in the area, as other ships or the infrastructure in the port. This is a large liability for ship owners and manifests itself in the expensive insurance premiums designed to cover such eventualities.
The Docking application by Upteko is primarily designed to provide assistance for sophisticated docking but the opportunities of Upteko’s applications are endless. The Docking application gives an option to the captain and the crew to choose the view of the ship they want helping them to pan through the docking process precisely without any collisions.
High-definition thermographic cameras along with infrared sensors make this entire system work not only during daytime but also in very low lighting conditions at night-time.
However, the docking application can also be used in many other scenarios such as navigating through narrow passages heavily trafficked with small boats and ferries.
Precise distance measurement helps smooth navigation through narrow and critical situations.
A high definition camera installed into the drone takes continuous footage of the ship, when required, which is then processed through the Semantic Segmentation Network integrated into the system. Semantic Segmentation Network helps to segment and identify different solid objects around the ship. A very precise distance of these objects is then measured by Ground Sampling Distance(GSD) technique which is then feed in real-time to the Captain, crew member of the ship, and others involved in the navigation process.
Search and Rescue.
In most Man Over-Board (MOB) scenarios, a person becomes unconscious in water after only a few minutes. Ships need a system to alert rescue crews seconds after a MOB situation occurs; a way for the coordinates of the person to be sent, a flotation device, and a lifeboat to the exact geolocation. This requires data beyond the line of sight.
Time is the most critical element in Search and Rescue operations for drowning incidents. The submersion time for people who survive intact or with mild neurological damage is less than 5 minutes (median), whereas the average for non-surviving victims is 16 minutes.
The likelihood of survival is very low in general for submersion over 10 minutes. This drastically improves with a flotation device.
A victim has an 80% higher survival chance, and a survival time of 2-4 hours (18x higher). Ship cruise speed is 18-20 knots (10 m/s), rescuers have a window of less than a minute to find and rescue a man overboard if the alert was raised when the person fell overboard.
Upteko’ Search and Rescue application calculate the position of people falling overboard. It has an application that is a standard for its multipurpose drone. The Charging station of the drone is connected to the AIS signal of the ship. In this way, it knows the speed of the ship, the direction of the wind, the underwater current, and the sailing path of the ship.
With this information, the direction of a MOB (man overboard) can be calculated, and how many centimeters this person would move in any direction per second.
With a short interaction with the system's computer from anyone with access to it, a command is given to the drone with a push of a button, and the drone takes off and activates the RGB and the thermal sensor.
The drone flies in the direction of the MOB and the thermal sensor with AI will detect the hotter pixels in the image and send the exact location back to the bridge, so a safety boat can be sent directly to the victim. this is especially an advantage at night where the MOB is most likely not visible in line of sight.
Pirates use small ships and attack large commercial ships at night. The board ships and take the crew and contents hostage. There are no mobile long-range detection tools with aerial insight to give the crew information about nearby pirates. Ship captains, therefore, avoid sailing past known danger zones (East Coast of Africa).
The total cost of piracy to the shipping industry, from insurance and time lost, is estimated at over €6B/year.
The Perimeter Control application by Upteko is designed to allow any member of the crew to investigate surrounding vessels approaching the ship. Within the drone system, a built-in feature is added to allows a crew member with no prior drone experience, to operate and control the aerial camera in any direction. The Perimeter Control application not only helps the crew to detect pirate attacks but also helps to analyze a critical situation like a thunderstorm in advance and therefore be prepared to manage the upcoming critical situation.
