Marine Communication and Alarm Systems

Clear communication is essential during routine operation and becomes critical during an emergency. Maretek supplies marine communication, alarm and information systems designed for shipboard environments, including hazardous and exposed locations.

Public Address and General Alarm

Public-address and general-alarm systems distribute routine announcements, operational instructions and emergency warnings throughout a vessel or facility. A marine system must deliver intelligible audio to the required zones and continue to support emergency communication under the relevant power and redundancy conditions.

Talk Back and Paging Systems

Talk-back systems support two-way communication in selected shipboard areas, while paging systems allow operators to reach individuals or groups through handset stations, hands-free microphones and speakers. These systems can improve coordination and safe working during deck, crane, machinery and cargo operations.

Marine Telephone Systems

Automatic Telephone Systems

Electronic telephone exchanges provide dependable internal calling between shipboard locations. Marine configurations are selected for the required number of extensions, environmental protection, interface requirements and operating reliability.

Common Battery Telephones

Common-battery systems support important conversations between locations such as the wheelhouse and engine-control room as well as general communications between onboard spaces.

Sound Powered Telephones

Sound-powered telephones provide an independent communication path that does not rely on the vessel's normal power supply. This makes them especially valuable for emergency communication between critical stations.

Intrinsically Safe Telephones

Intrinsically safe telephones are intended for hazardous areas where flammable gas may be present. The source material refers to equipment designed for an IIC T6 hazardous-area classification. Suitability must be verified against the final zone and certification requirement.

Master Clock and Time Distribution

A marine master-clock system distributes consistent time and date information to clocks, monitoring systems and data-logging equipment. GPS and NMEA data can be used to update vessel time, supporting coordinated records and operations across onboard systems.

Sound Reception Systems

Sound-reception systems help enclosed wheelhouses detect external acoustic signals such as another vessel's whistle. The system transmits the sound into the wheelhouse and provides a visual indication of its direction, supporting situational awareness.

Communal Aerial Systems

Marine radio and television distribution systems use aerials, amplifiers and onboard cabling to distribute selected broadcast bands to multiple locations. System design should account for signal sources, coverage, interference and the vessel's accommodation layout.

CCTV and Integrated Bridge Systems

CCTV enables observation from a central location when direct access is unsafe or impractical. Monitoring may be continuous or event-based. Integrated bridge systems bring sensor information and selected command functions together at coordinated workstations to support navigational safety, operational efficiency and effective bridge resource management.

Design Clear Communication Across the Vessel

Maretek can help define communication zones, equipment types, environmental ratings, interfaces and approval requirements for a coordinated marine communication solution.
