Technology that strengthens the connection

For decades, IHM has supported maritime authorities, ports, and rescue services with reliable communication and monitoring. We know what it takes to keep operations safe in environments where systems and signals must work seamlessly across radios, networks, and frequencies.

Ports and Coast Guards

Overview from shore

IHM’s communication solution for SAILOR radios is designed for ports and coast guard units operating with a small number of radios, a single operator position, and remote base stations.

The solution extends radio coverage for port authorities — especially in areas with challenging approaches — and the interface is developed in close collaboration with operators to ensure a clear view of traffic, incidents, and available resources.

The result is a simple yet comprehensive setup that gives ports and coast guards a reliable tool for maintaining safe and efficient operations, even under pressure or difficult conditions.

A simple extension

IHM’s solutions are flexible and can be expanded with additional features, giving you a setup that matches your operational needs.

By adding, for example, a TETRA module or a Ground-to-Air extension, operators gain the ability to communicate with other systems used by aircraft, helicopters, police, and national security units.

A VTS solution expanded with TETRA offers

Integrated telephony with call transfer for VHF and MF/HF

Automatic call recording

Design compliant with GMDSS requirements, including integration of:

DSC – Digital Selective Calling
MSI – Maritime Safety Information
ATIS – Automatic Terminal Information Service
NAVTEX – Transmission and reception of NAVTEX messages

Onshore – offshore

Dynamic operations

With growing demands for safety, environmental protection, and operational reliability, IHM has developed a setup for both onshore and offshore maritime operations.

The technology enhances monitoring, coordination, and communication between vessels, rescue units, and authorities — across national waters and international boundaries.

By bringing all systems together in one integrated platform and shared network, much of the operational control can be moved from offshore sites to redundant, land-based control centres — increasing flexibility and reducing operating costs.

The solution offers:

Full VoIP integration between shore and sea
Centralised control of multiple radio and network types, including TETRA, VHF, HF and satellite links

GMDSS-compliant software
Automatic activity logging
Redundant architecture with automatic failover between control centres

A flexible and scalable system that supports close coordination between onshore and offshore operations — ensuring continuity, clarity, and fast response, even as conditions change.
