Intelligent marine navigation systems refer to the use of multiple sensors and intuitive software to identify and alleviate various maritime navigation safety risks. Such advanced technology enables navigation personnel to monitor numerous safety parameters and ensure optimum intelligence during night time and adverse weather conditions. Some of the latest intelligent marine navigation systems fuse data from several sources and provide a unified visualization using virtual and augmented reality (AR & VR).
Marine actuators and valves are the components installed in the marine vessels for their proper control and smooth working. Actuators are the devices which are used to convert different forms of energy into mechanical motion. These motions are used to actuate different control system within a marine vessel. Similarly, valves are the devices which are used to restrict or regulate the flow of fluid related to different operations in the marine vessel.
By 2030, the marine vessel market is anticipated to surpass $200 billion in revenue. The demand for ships rises during periods of economic expansion and falls during recessions. According to the United Nations Conference on Trade and Development (UNCTAD), over 80% of world trade is conducted by sea. Thus, it is evident that maritime transport is an engine of global trade and economy that closely tracks the nation's GDP growth. Over the forecast period, it is expected that the market would expand at a sluggish but constant rate.
Massive maritime vessels consume a great deal of fuel and contribute to global warming as a result. Yet, fuel costs account for the majority of shipping company expenses. Hence, energy efficiency improvement is the primary engine of innovation in the transportation business. Due to the efficiency and cost-effectiveness of the hybrid propulsion system, the conventional fuel-based propulsion system is being replaced by the environmentally friendly hybrid propulsion system. In hybrid marine propulsion systems, renewable energy, such as solar energy, is frequently used as a storage option. In this method, solar energy is employed at peak hours or at night, decreasing the demand for traditional marine fuel 24 hours a day, seven days a week. In addition, stringent laws regarding the reduction of carbon emissions have raised the market for hybrid propulsion systems.
By implementing hybrid propulsion systems, the maritime industry is emphasizing efficient commerce shipping. In such a circumstance, marine boats can utilize both conventional and sustainable energy sources. Several firms' technological advancements enable marine vessels to run on traditional maritime fuel during the day. They can also be pushed at night utilizing the solar energy storage system installed aboard ships. It would reduce the need for traditional maritime fuel on a constant basis. Autonomous ships and electric ships are the two primary developments that have had a significant impact on the marine industry.
The automation and integration of new ships, as well as the retrofitting of older vessels with hybrid and electric propulsion, are becoming increasingly important to shipbuilders and operators. This is in compliance with the IMO 2020 requirement. According to this guideline, ship operators must use fuels with a sulfur concentration of no more than 0.50 percent, as opposed to the present limit of 3.50 percent. Hence, ship integrators and owners are replacing their diesel-powered engines with electric or hybrid propulsion. Several ship owners from Norway, the United States, Greece, China, and France are aggressively retrofitting their existing fleets with hybrid and electric propulsion systems. For instance, Wartsila signed an agreement with Hagland Shipping AS in January 2019 to refit its diesel-powered general cargo vessels with battery hybrid propulsion for short-sea transportation. Governments in North America and Europe are pushing for a cleaner means of canal transport, as hybrid and completely electric passenger vessels are in high demand and have significant potential in their respective regions. In addition, the operating costs of an electric vessel are significantly less than those of a diesel vessel.
