The Evolution of the Unmanned Surface Vehicle (USV)
If you're interested in the Unmanned Surface Vehicles (USVs) market, you will be glad to know that the demand is rising, especially with the COVID-19 pandemic. However, you also have to bear in mind some challenges.
Challenges faced by USVs
Unmanned surface vehicles (UUVs) are a type of unmanned aerial vehicle (UAV). These robots are specially designed to address environmental issues. They can be deployed for various purposes, such as search & rescue and damage assessment. UUVs also can operate in a wide range of environments.
There are some different challenges that UUVs face, including water force and navigation, obstacle avoidance, and safety. For example, water force can knock an acoustic camera out of alignment, and it is often difficult to accurately localize a UAV in the water.
Situational awareness is a primary function of USV sensors in disaster sites. This may include underwater mapping sensors, microphones, speakers, and 360 cameras. A bird's eye view can help general navigation and detect hazards in the vicinity of the USV.
Some examples of mature USV applications are structural inspection, flood forecasting, and SAR. While these applications are relatively common, many other potential applications exist for UUVs. Many are still experimental.
There is also a lack of research on the effectiveness of UUVs in the harshest conditions. A few studies have been conducted in this area, but most focus on technology. Most research teams aren't multidisciplinary enough.
The two main issues are the lack of reliable testing sites and the cost of reproducing extreme conditions. It would be beneficial to develop training exercises to prepare emergency response personnel to use UUVs.
Surface vs sub-surface segments dominate the market
The use of Unmanned Surface Vehicles (USV) for disaster management in aquatic environments is evolving. Many studies focus on technology, but there is little research on how USVs perform in extreme conditions.
These vehicles are sometimes used for environmental monitoring and various other applications. They can provide different perspectives on a disaster site. For example, they can be used to inspect bridges and other structures. UUVs are specially designed to operate in a wide variety of environments.
One application developed using a combination of a USV, and a UAV is river mapping. This requires the integration of a sensor to collect data on the surface. Once the data is collected, it can generate an ultra-high-resolution image.
A second example is bathymetry surveys. These can be performed during high tides, allowing the USV to be close to shore. It is also possible to conduct the surveys during the tidal cycle when the water is relatively calm.
Bathymetry instruments are an essential tool for many problems. However, their accuracy can be adversely affected by the environment. Some issues include shadowing and line-of-sight occlusion. There are also some limitations in sensor performance.
Another advantage of UUVs and USVs is their ability to travel through debris. They can help reduce labor costs during the cleanup process. Moreover, they are capable of providing communication infrastructure. Ultimately, they can provide the benefits of a remote ground station with the advantages of an underwater system.
More than 1000 hours is the dominant segment in the global USVs market
Unmanned surface vehicles (USVs) are versatile platforms for oceanic and littoral surveys. They are specially designed to address environmental issues. Their use is particularly effective for flood mitigation and response.
The first application for USVs was for bridge scour assessment. In this task, a team of divers and engineers to assess the condition of a bridge. Scour erosion can result in dangerous situations for the inspection crew.
Another mature USV application is the structural inspection of concrete. Using USVs to inspect a concrete structure allows for identifying cracks and other defects in the material. Segmentation is also used, analyzing concrete regions to detect damage and water deterioration.
Several other applications have been developed, including searching and rescuing people in the water. Some current projects are tow-boom applications, which deploy a boom that carries the USV toward the target.
Unmanned aerial vehicles (UAVs) are also helpful for disaster response. Hurricanes, earthquakes, and other natural disasters can result in flooding. These events can damage a variety of infrastructures. If a hurricane strikes, UAVs can be deployed to provide unavailable observations from satellites.
Floods are a common motivator for the research and development of USVs. However, a lack of testing sites is a crucial concern for USV reliability. Only a few papers have tested USVs in disaster scenarios.
Other challenges include obstacle avoidance and communication. USVs are not always easy to control, and operators may encounter confusion if unfamiliar with the task.
Deep-submergence vehicles will always be a primary driver of innovation
One of the most exciting types of unmanned surface vehicles is the deep-submerse varieties. The enigma is that most are conceived as a means of securing cargo, not to mention their occupants. Hence, they will likely remain in the laboratory for the foreseeable future. Nevertheless, there is no reason to doubt that innovation and advancements will continue, albeit at a slower pace. In particular, there will be an increased emphasis on securing cargo, which is one of the many challenges of today's world. To that end, companies are innovating in a variety of ways. These innovations include more pedestrian functions, such as deploying smart sensors and advanced control systems. A more challenging task is the development of autonomous capabilities capable of taking on the more demanding task of transporting cargo from one location to another. Although a slew of challenges lay ahead, one solution, in particular, has become a focal point of the industry: a standard protocol for unloading and reloading cargo. This is an essential step in the evolution of unmanned surface vehicles.
Maritime Autonomous Surface Ship UK Industry Conduct Principles and Code of Practice
The MASS UK Industry Conduct Principles and Code of Practice is a set of rules and guidelines that the Maritime Autonomous Surface Ship (MASS) industry can adhere to. These include training standards, identification and registration of MASS vessels, operational and evaluation deployment planning, and qualifications needed to operate a MASS system.
Rule 8 of the Code of Practice identifies two key training areas. One is related to the navigational data available to a MASS. Another is for the remote personnel management of a MASS.
Besides being an excellent tool for companies seeking new contracts, the code provides quality assurance to companies experimenting with MASS systems. According to Maritime UK, the updated code version focuses on operator training, identification, and registration standards.
Rule 7a addresses the risk of a collision. The risk is dependent on the speed and distance of the vessel. For example, a TCPA of six minutes would be considered a high risk, while a CPA of 0.5 nautical miles might be considered low.
COLREGs, or Collision-Of-Last-Right-Of-Vessels, are a vital part of ensuring navigational safety. They cover the various elements of a vessel's movement, such as steering, sailing, lights, and sound signals. However, COLREGs are not always clearly understood or adequately executed.
The IMO has announced a regulatory scoping exercise for unmanned ships. This is an essential step in the development of autonomous vessels.
Rising demand due to the COVID-19 pandemic
The COVID-19 pandemic has changed the landscape of the shared mobility industry. It has impacted travel, shopping, and leisure activities. In addition to restricting access to public transit, the disease has affected all modes of urban transportation.
COVID-19 restrictions have also harmed the unmanned surface vehicle (USV) market. These restrictions have disrupted maritime activities, including cargo flow and origin country activities. Some countries, such as China, are engaging in conflicts with their neighbors in the South China Sea.
Unmanned surface vehicles are machinery operated remotely over water surfaces. They are used in several military missions, ocean mapping, and surveillance. A variety of sensors are utilized to build these vehicles.
Due to the rapid pace of globalization, many countries have sought to gain control over their maritime trade routes. Maritime insecurity has been an essential factor in terrorist attacks against maritime targets. While terrorists have had different motives, traditional geopolitical disputes have also increased the demand for maritime surveillance.
The COVID-19 outbreak has created an unprecedented need for research into the remote operations of unmanned surface vehicles. This research can identify vulnerabilities and opportunities for improved autonomy.
The USV market is expected to expand due to increasing ocean data mapping and marine surveillance demand. Increased budget for technological upgradation in the defense sector is also driving growth.
The USV market will also be impacted by the world's rapid urbanization. Unmanned surface vehicles are more efficient and less expensive than traditional research vessels. However, the need for clearer navigation rules is projected to hinder the market in the coming years.
