Communication solution for Maritime


Most maritime control centres around the world are observing increasing traffic in ports, on rivers and within national maritime borders. Stricter international environmental requirements, together with search and rescue operations, are increasing demands on communication systems for both ports and coastguards.
Maritime control centres typically monitor shipping traffic in local, very busy waters, such as approaches to and exits from industrial ports or narrow river passages. Coastguards usually handle activities at national level, with cross-service coordination (police, customs, and military). Both types of control centre need to establish an effective communication system that works across the different platforms used. This challenge grows when neighbouring countries and their authorities are also involved.

A broad and varied range of activities
Both coastguards and maritime control rooms handle a wide variety of tasks to ensure a safe and efficient approach to ports, rivers and national waters. Activities range from service to shipping, to surveillance and operations

To combat illegal fishing operations
To monitor immigration
To combat piracy
Connected with environmental activities

And communication and coordination of
Traffic services
Traffic routing
Search and rescue
Environmental activities
This wide variety of tasks makes heavy demands on communication systems in control rooms and at coastguards. There is a serious need for communication systems that connect the various platforms and systems to ensure the safe and effective performance of tasks.

Future-proof solutions
IHM has 25 years’ experience in control room solutions and radio communication and telephony solutions for ports and coastguards all over the world. The systems can handle communication between land-based units, aircraft and ships. Our coastguard and control room solutions are modular, which means they can be scaled up or down and new facilities can be added as needs change.

IHM’s solutions for maritime control rooms and coastguards ensure:
Communication across a variety of radio communication systems and platforms
Two-way communication from land to ships and aeroplanes, and between ships.
Hierarchical structure, with local, regional and national control centres
Automatic recording
A solution designed according to GMDSS regulations
24/7/365 service and support
IHM offers a range of maritime solutions, both large and small, and all can be scaled up or down according to your specific requirements. Solutions include products such as COM4500MCS from IHM’s maritime systems. These can be supplied with several levels of redundancy, according to your needs.

IHM’s control room solution for coastguards and ports ensures simple and effective communication, both in the local area and over large distances. It also ensures trouble-free technical communication between the various task forces — locally, nationally and across borders.
Our 35 years of experience in control room solutions for the maritime industry ensures a simple and effective communication platform that solves the challenges associated with communicating across different systems, at sea, on land and in the air.

We supply one complete communication system based on know-how and experience of the industry.

The solution ensures:
Two-way communication from land to ship via VHF-MF/HF or satellite link
Units can be stand-alone yet still be operative
A task can also be taken over, for instance, by a national control room
Communication is possible across a variety of radio communication solutions
Standardised operation of all types of radio communication systems
The solution is designed to support communications tasks related to shipping services and surveillance of:
Coastal areas
National waters
Information about traffic conditions
Communication of conversations, etc.
The systems comply with current regulations for GMDSS systems. This means that IHM can supply a complete system for installation as a port system or as a communication system at a national communications centre.

Knowledge sharing means more effective operations
The IHM solution is distinctive in that it is a system composed of local control centres, connected in a network, for example, with one national control room and a number of regional control rooms or operator units.

We can also provide key expertise where needed. If an operator requires special expertise to coordinate a rescue operation, the national control centre can either provide the necessary expertise or take over communications and coordination of the task entirely. If a unit is disconnected, the national control unit can take over monitoring and coordination of the task until contact to the unit has been re-established.

Simple upsizing
IHM’s solutions are flexible and numerous extra functions can be added. For example, if you add an IHM TETRA solution, or a ground-to-air solution, operators will also be able to communicate with other communication systems used for aeroplanes and helicopters, police and other national services.

The VTS solution with TETRA extension includes the following functions:
Integration of telephony with an option for connecting calls on both VHF and MF/HF
Automatic recording of calls
A solution designed according to GMDSS regulations, which enables integration of:
DSC (Digital Selective Calling) signalling
MSI – Maritime Safety Information
ATIS – Automatic Terminal Information Service
NAVTEX – Transmission and Reception of NAVTEX messages
Integration with an analogue system
IHM’s solution for coastguards enables integration between the maritime communication platform and an analogue/digital system, which is used for communication between land-based and/or airborne units.

Integration is established by cabling the coastguard’s communications centre directly to one or more base stations in the analogue communication system.

The integration option enables operators at the control centre to communicate within the land-based communication system, where they can patch calls from units in one system to units in another.

Control room solutions with this integration option provide the following functions:

Individual calls
Communication to groups of radios
IHM offers a range of solutions, both large and small, and all can be scaled up or down according to your specific requirements. Solutions include products such as IHM IP Switch, DSC, MSI, NAVTEX and ATIS.


Coastguard tasks are becoming increasingly complex. They involve several different task forces and services within national borders as well as the task forces of neighbouring countries. Different communication platforms and systems obstruct effective coordination, ultimately costing lives.

One solution integrates numerous radio and telecommunication systems
IHM bases its integration of different radio systems on an analogue solution, which is a feature of IHM’s control room.

With this solution, operators can communicate with other communication systems, including digital systems used for aeroplanes and helicopters, police and other national services. Using a monitor and a panel with standardised functions, an operator can easily and efficiently control operations across professional groups and borders.

The solution includes:
Integration of other types of radio communication systems, with an option to connect calls between them
Integration with the radio systems of other users, such as police, fire and rescue services
Standardised operation of all types of radio communication systems
Automatic recording of calls
Service agreement with 24/7/365 support

The following options can be added to the solution:
DMR system integration
Analogue system integration
IHM offers a range of solutions, both large and small, and all can be scaled up or down according to your specific requirements. Solutions include products such as IHM COM4500MCS.
