Ship Electronics

Electronic devices classed for use in the marine environment. All electronics used onboard must be designed to fit in the small confines of a bridge and can come in contact with salt water, so they are made to be very water resistant or waterproof. A wide variety of marine electronics are available in the marketplace. Some common devices found on modern ships are:

Autopilot and/or self-steering systems

These systems must coordinate data from many devices on the ship and interface with control and propulsion systems to keep the vessel on a predetermined course.

Chartplotter

A chartplotter is a device used in marine navigation to combine GPS data with an electronic navigational chart (ENC) to display the position, heading and speed of a vessel, and may display additional information from radar, automatic information systems (AIS) or other sensors. Electronic chartplotters must be used with one or more computers, and may also display data from other sensors, such as echolocators, radar and/or sonar, or automatic information systems.

Compass

Modern ship compasses use a series of fibre optic gyroscope sensors and computers to locate north. This system usually includes sensors, control and display equipment, and an interface linked with the ship's other navigational devices and global positioning system.

Sonar (or Fishfinder)

Acoustic devices using electronically emitted and detected pulses of sound to locate underwater objects. These include transmitters, receivers, and equipment used to analyze acoustic information.

GPS

Global Positioning Systems are space-based radio-navigation systems that broadcast highly accurate navigation pulses to users on or near the Earth.

Fuel monitoring and management

The rising prices of marine fuel and heightened emissions regulations have led to advances in the technology used to measure, monitor, and report fuel use. Electronic MFM devices can reduce fuel costs and increase operational efficiency.

Marine VHF radio

Marine VHF radio is used by all large ships and most seagoing small craft to summon rescue services and communicate with harbors, locks, bridges and marinas. A marine VHF set combines a transmitter and receiver and only operates on standard, international frequencies specified for marine use.

Radar

Radar is an object detection system that emits electromagnetic waves and analyzes their interaction with objects. Radar systems are able to identify the range, altitude, and velocity of moving and stationary objects such as aircraft, ships, ground vehicles, and meteorological formations.

The future fleet will be characterized by networked, intelligent, and highly adaptable platforms, operating across multiple domains to secure sea lanes and project power more effectively than ever before.

Drug Smuggling on Ships and Submarines: An Escalating Threat

Drug smuggling has long been a lucrative enterprise for criminal organizations worldwide. With the increasing sophistication of law enforcement agencies and border controls, smugglers are continuously adapting their methods. One of the most challenging trends to combat is the use of ships and submarines to transport illicit drugs across international waters. This article explores the methods, routes, and challenges associated with maritime drug smuggling.

Tanker Vessels are vital links in the global supply chain

Tanker ships are an important component of the maritime sector, and they transport liquid cargoes around the world. These vessels are vital to the supply chain for energy, chemicals and other essential commodities. There are many types of tankers, each designed for specific cargoes such as oil, LNG, chemicals, or other liquids.
