IMO Updates GMDSS Installation Guidelines for Safer Seas

25

  • The revised guidelines aim to standardize radio equipment installations on SOLAS-compliant ships for improved safety and efficiency.
  • The scope covers various vessels, including SOLAS ships, high-speed craft, mobile offshore drilling units, and certain smaller vessels.
  • Key focus areas include installation standards, energy sources, antenna placement, electromagnetic compatibility, and operator training.

The International Maritime Organization (IMO) has updated its guidelines for installing Global Maritime Distress and Safety System (GMDSS) radio equipment on SOLAS-compliant ships. Approved during the 109th session of the Maritime Safety Committee, these revisions aim to enhance consistency and safety in maritime communication, DANCOMPLIANCE reports.

Purpose and Scope of the Revised Guidelines

The guidelines provide shipowners, operators, and manufacturers with standardized instructions for installing GMDSS radio equipment.

While primarily focused on SOLAS-compliant vessels, they also apply to certain smaller vessels where practical.

Technical and Regulatory Requirements

The guidelines outline essential compliance measures based on IMO resolutions, ITU regulations, and STCW standards.

They ensure proper redundancy, functionality, and interoperability of GMDSS equipment across different sea areas.

Equipment and Installation Standards

Key provisions cover VHF and MF/HF transceivers, EPIRBs, AIS-SARTs, and portable radios. Additionally, recommendations for bridge integration, emergency readiness, and proper antenna placement ensure optimal performance.

Energy Sources and Electromagnetic Compatibility

The guidelines specify requirements for main and backup energy sources, including batteries and uninterruptible power supplies (UPS).

They also address electromagnetic compatibility (EMC) to prevent interference with other onboard systems.

Environmental Considerations and Training Responsibilities

Recommendations for responsible disposal of obsolete equipment aim to reduce environmental impact.

Marine electronics companies are tasked with ensuring ship operators receive proper training before activating the GMDSS systems.
