A transducer is any device used to convert energy from one form to another, such as a conversion from mechanical to electrical energy or vice versa. An electroacoustic transducer is a device that converts acoustic energy (sound) into electrical energy (voltage or current) or vice versa.   Piezoelectric materials modify …

The International Energy Agency’s has found that the accelerating demand for electricity – due to a growing global population and rising levels of affluence – is on course to outpace the growth of renewable energy and increase reliance on fossil fuels.   The International Maritime Organization has adopted mandatory measures …

A stealth ship is a type of ship which is especially used as a war vessel and is concealed from the navy vessels of other countries. It is an important warfare tactic that is used by nations wide across the world. Since they are invisible but the opposite navy vessels …

Globalization has opened the doors for trade across the world and it has thus become necessary for ships to be equipped with the latest forms of communication and technology. Communication is vital for the safe navigation and management of ships. Marine communication involves ship-to-ship and ship-to-shore communication. Cell phones are …

The seas are becoming increasingly congested, with the IFT Transport Outlook 2019 predicting that demand for maritime trade could triple within the next 30 years. A large number of ships raises the chances of the collision.  Although the number of serious collisions  has fallen within the past decade with 132 …

An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by …

Maritime networks have become an attractive playground for hackers, with cyber-attacks on vessel OT networks and systems increasing by 900% over the past three years.  A ship’s onboard information technology and operational technology systems can be hacked just as easily as systems ashore. Such security breaches have the potential to …

Most of the ocean is unknown. Yet we know that the most challenging environments on the planet reside in it. Understanding the ocean in its totality is a key component for the sustainable development of human activities and for the mitigation of climate change, as proclaimed by the United Nations. …

A hydrophone is an underwater listening device, just as a microphone is used to detect sound in the air. Hydrophone detects sounds in the water and converts the acoustic energy into electrical energy by detecting changes in pressure in the surrounding environment. Hydrophones listen to sounds in the sea, but …
