Maritime Emergency Lighting: Technical Requirements and Selection Criteria

Discover the engineering behind SOLAS-certified lifejacket and lifebuoy lights and why international compliance is vital for offshore safety.

In maritime and offshore operations, maritime emergency lighting plays a critical role: ensuring that people in the water can be located quickly, even in low-visibility environments. To fulfill this vital function, it is essential to evaluate technical requirements, international certifications (such as SOLAS), and suitability for continuous use in highly corrosive saline environments.

Technical Criteria for Selecting Maritime Emergency Lighting

Engineering parameters for maritime emergency lighting:

1. Luminous intensity (cd) and emission pattern:
   Long-distance visibility.
2. Operational autonomy:
   Adequate for search and rescue (SAR) response time.
3. Activation type:
   Automatic (water-activated), manual, or hybrid.
4. Floating position:
   Maintaining the light beam above the waterline.
5. Resistance:
   Appropriate IP rating and protection against saltwater corrosion.
6. Mechanical robustness:
   Resistance to impacts and severe vibrations.
7. Certification and traceability:
   Full equipment compliance.

SOLAS Compliance and Brazilian Navy Requirements

The SOLAS certification establishes rigorous performance parameters for maritime emergency lighting, including luminous intensity and battery life. It is important to highlight that the Brazilian Navy, in its safety regulations for navigation (NORMAM), accepts and reinforces the adoption of equipment with International SOLAS Certification, ensuring that the vessel is in global compliance.

Battery Technology: Lithium vs. Alkaline

• Lithium Technology: The preferred choice due to its superior power and ability to operate at extreme temperatures. While the SOLAS requirement is 8 hours at 0.75cd, Daniamant’s lithium lights can last up to 90 hours.
• Alkaline Technology: A reliable alternative that meets all SOLAS and Marine Equipment Directive (MED) testing requirements, with a lifespan of up to 60 hours, facilitating transport and disposal.
