The Top 10 Technology Trends 2020 – 2030
Progressive technologies are used in any industry and shipbuilding is no exception. This article contains 7 main directions of technological development for the next decade..
Unmanned ship control technologies
They say that the captain should leave the sinking ship, but this statement is no longer relevant for the Hushcraft ship, which has no sailors on board at all. In May, an unmanned aluminum ship with a height of 12 meters English Channel and successfully completed the task of delivery from the UK to Belgium.
The small cargo boat is powered by electric generators and a diesel engine, and the eyes are a variety of thermal and video cameras. Approaching ships receive an automatic identification system signal about the presence of a drone..
The advantages of using such floating devices for the delivery of goods are to save money in the galley, without the possibility of death of sailors or their capture by pirates. Also unmanned arm ships for the needs of the navy.
The idea of a ship without a crew has faced a lot of justified criticism regarding GPS system failures and liability for accidents. If disabling GPS navigation is not a big problem for an experienced captain, then the ship from Hushcraft can cause an accident or simply get lost in the endless expanses of ocean waters, causing the greatest losses. In the modern world, news about lost ships is perceived with surprise, but it happens regularly. Just two months ago, there was a massive GPS failure, which left more than 7,000 ships lost and forced to return to control the old fashioned way..
Polymer composite materials
As they improve efficiency continuously, they reduce production costs and significantly reduce operating costs. The lighter the boat, the more fuel it can hold. Due to the lightness of polymer materials, long-distance sailing boats stay on the water longer without the need to make an additional hook for refueling.
A thin sheet consisting of carbon nanotubes (CNTs) has found application in shipbuilding. A CNT sheet in comparison with steel weighs 10 times less, which does not prevent it from being 500 times stronger. However, such indicators can be achieved only with the use of composite materials. Polymer composites have greatly facilitated the work of design engineers. In addition, composites are excellent at absorbing sound, vibration and radio waves. The latter property is especially useful for military ships, including submarines..
For several years now, Russian shipbuilding technologies have applied innovations in the production of multiaxial and release fabrics, sealing harnesses and nets for resin distribution. The leaders in this industry are «Composite cluster of St. Petersburg» and «United Shipbuilding Corporation».
Additive technologies enable high-strength steel and titanium to be printed faster and cheaper. The main advantage of a 3D printer is that it is able to print a form in the shortest possible time, which cannot be obtained by another method. In Russia, this area is dealt with by the Leningrad University and St. "Small ship". Through the interplay of 3D printing and the unique properties of composite materials, engineers «Small ships» were able to build a fiberglass hull 79 meters long and 8 meters high, having done all the work in one fill.
Using 3D printers can be helpful for quickly replacing a broken ship part. Certified additive propellers already exist. Navantia implemented a project called 3DCABINS, which printed modular toilets and ventilation grilles, which were characterized by light weight and low cost of production..
In recent years, there has been a growing number of sailing sources that use solar panels and other renewable energy sources. Engineers remembered creating carbon masts with automatic sail control without human intervention. Such sails have the power of recuperation (reuse) of wind force by means of two traction controlled propulsion systems operating in the generation mode. These installations feed the yacht with 500 kilowatts of electricity..
For several years now, the world’s largest solar-powered ship has been the MS Turanor PlanetSolar. Last year, the use of solar panels, which were installed with a total area of 537 square meters, was installed with a total area of 537 square meters…
Modern methods of robotics significantly reduce injuries during welding, including underwater welding. Shipbuilding industry work with specific welding jobs: welding titanium with a thickness of more than 110 mm, welding structures that can withstand immersion to a depth of 12 km and This low popularity of this profession among young people, there is a shortage of qualified labor..
The leader in this industry can be safely called the South Korean plant Geoje, which in 2014 replaced 68% of human labor in shipyards with robots. Application not only for construction manipulators, but also for serving spider robots for cleaning pipes from rust and further painting. Also, different types of exoskeletons are used to facilitate human physical labor…
Vessel construction without ballast and LNG
Ballast is essential for any vessel to maintain stability, but ballast water management tightened in September 2017, when an international convention obliged all ships built after that date to be equipped with a ballast water treatment system. The cleaning technology is expensive, so engineers began to look towards ships without ballast..
Hyundai Mipo Dockyard unveiled a bunkering gas project last year that is sustained by optimizing the shape of the ship’s hull and hull lines without having any ballast. In the bow of the ship, as a rule, there is, as is usually the case..
Driving Force Liquefied Natural Gas (CNG) Engines – another new trend in shipbuilding, which is being set by the international maritime organization for emissions of carbon dioxide in the atmosphere. CNG engines reduce CO2 emissions by 20-25% compared to diesel counterparts.
Wartsila, MAN Diesel are actively developing in this direction. & Turbo, but the lead was taken by Deen Shipping. It was the first to develop an LNG chemical tanker with a capacity of 6,100 tons, although 20% of the tanker’s capacity is still supplied by diesel..
