International Code 86

The International Code of Signals, also known as the International Code 86 or simply INTCODE, is a standardized system of signals and codes used for communication between ships, ships and coastal authorities, and other maritime interests. This system was developed by the International Maritime Organization (IMO) to provide a universal means of communication that can be understood by all, regardless of the language spoken on board ships or in coastal stations.

History and Development

The International Code of Signals has a long history, dating back to the early 20th century. The first version of the code was adopted in 1931, but it was not until 1969 that the code was comprehensively revised and updated to become the modern International Code of Signals that we know today. The code has undergone several revisions since then, with the most recent revision being the 2005 edition, which is commonly referred to as the International Code 86. This revision introduced significant changes, including the use of new signal flags and the introduction of a standardized system for communicating navigation and safety information.

Structure and Content

The International Code of Signals is a comprehensive system that includes a wide range of signals and codes for use in various situations. The code is divided into several sections, each dealing with a specific aspect of maritime communication, such as navigation, safety, and distress signaling. The code includes a total of 26 signal flags, each with a unique meaning, as well as a range of other signals and codes, including Morse code and radiotelephony procedures. The code also includes a range of standardized phrases and messages, known as standard messages, which can be used to convey common information, such as position reports and weather forecasts.

Use and Application

The International Code of Signals is used by ships and coastal authorities around the world to communicate a wide range of information, from simple messages, such as position reports and weather forecasts, to more complex information, such as navigation and safety warnings. The code is also used in emergency situations, such as distress signaling and search and rescue operations. In addition to its use in maritime communication, the International Code of Signals is also used in other areas, such as aviation and military communication, where a standardized system of signals and codes is required.

Training and Certification

To use the International Code of Signals effectively, it is essential to have proper training and certification. The IMO provides a range of training materials and courses, including the International Code of Signals course, which covers the basics of the code and its use in maritime communication. In addition, many countries require ships’ officers and crew members to hold a certificate of competency in the use of the International Code of Signals, such as the GMDSS (Global Maritime Distress and Safety System) certificate.

The International Code of Signals is an essential tool for anyone involved in maritime communication, from ships' officers and crew members to coastal authorities and search and rescue teams. Its standardized system of signals and codes provides a reliable and efficient means of communication, helping to ensure the safety of ships and their crew, as well as the prevention of accidents and pollution.
