Whether you are in the market for a new boat or are looking to upgrade your current one, you can be sure that many innovative and exciting things are happening with Florida marine construction. From uncrewed surface vehicles to electric propulsion technology, there is something for everyone to explore.
LNG fuelled ships
Several innovative things are happening with marine construction, LNG fuelled ships, and other alternative marine fuels. These include a study on life cycle cost assessment (LCA) for marine fuels, a global map of LNG bunkering facilities, and an examination of the environmental impact of LNG.
LNG is a cleaner burning fuel that has many environmental benefits. It minimizes sulfur and nitrogen oxides and releases only carbon dioxide. These benefits have led to increased use of LNG in the maritime industry.
However, using LNG in the maritime industry has also faced several challenges. For example, many companies in the LNG sector had invested in LNG investments only to lose those investments when the LNG market did not take off as expected.
Robots in shipbuilding
Traditionally, shipbuilding has been a labor-intensive industry. To meet demand, shipyards have been investing in robotics. These systems can work longer and provide higher-quality welds than human workers can do. They can also monitor the worksite and solve problems quickly.
The rise of more intelligent robots also makes human workers’ jobs safer. These systems also improve efficiency and can access areas where people cannot. The increase in efficiency should lead to increased loyalty and financial benefits for shipbuilders.
The global shipbuilding robotics market is divided by regions. The Asia-Pacific is expected to dominate the market during the forecast period. This market is also projected to witness rapid growth due to the presence of major industrial robot manufacturers in the region.
Uncrewed surface vehicles (USVs)
Various countries are working on developing Unmanned Surface Vehicles (USVs). This new type of vehicle can be used for different purposes. It is expected to provide many benefits to the maritime industry. They can perform various missions, such as collecting ocean data, defending against small boats, and training and supporting other uncrewed vessels.
A particular class of USVs can be powered by wave energy, solar energy, or wind energy. These vehicles are suitable for long-range operations, but operational costs remain high. The proposed USV has been designed to minimize operational costs and to make it portable and recoverable.
The central electrical installation of the USV includes batteries, solar panels, and electronic components. In addition, the underwater unit is retractable using an electrically operated winch. A Digital Motion Processor is used to control the data acquired. The USV also features a custom-designed web application for controlling the vehicle. The online website can display sensor readings and allow users to change positions.
Integrated electric propulsion technology
Integrated electric propulsion technology in marine construction combines propulsion power with power station power. This technology reduces the total cost of ownership, increases efficiency, and provides system redundancy. It also reduces emissions. In addition, electric ship propulsion systems improve vessel survivability.
China’s breakthrough in electric propulsion is of great strategic significance. It is a result of national engineering equipment design and manufacturing capabilities. The country has developed an industrial base in critical technologies, such as diesel and megawatt-class diesel engines, medium and high-voltage power distribution boards, and electric motors.
Integrated electric propulsion systems provide a broad range of operation modes. It also offers a low noise signature and a high level of shock resistance. It reduces the need for controllable pitch propellers and gear trains.
Buckypaper
Buckypaper is a thin sheet made of compressed carbon nanotubes (CNTs). They are ten times lighter than steel and can be stacked together to create a composite material. They are also solid.
The nanotubes have atomic bonds twice as strong as diamonds and are ten times smaller than a human hair. They can make super-hydrophobic coatings for marine surfaces to reduce friction, frictional heating, and corrosion. These coatings may also be used to prevent marine organisms from growing. They could be used to create more robust and lighter ships than steel. This would increase energy efficiency and reduce fuel consumption.
Buckypaper is being investigated by several research groups worldwide. One of these groups is at Florida State University’s High-Performance Materials Institute (HPMI) in Tallahassee. HPMI has been working on the buckypaper for several years, and they have developed a manufacturing method that allows them to produce buckypaper in larger sizes.
