Marine Lifebuoy Ring

About product

A marine lifebuoy ring is a life preserver designed to comply with the 1996 Amendment to the International Convention for the Safety of Life at Sea, 1974 (SOLAS74/96). It is typically constructed using lightweight materials such as cork, foam, or other materials with a small proportion. The lifebuoy ring may feature a casing made of canvas, plastic, or other suitable materials. It must adhere to the regulations outlined in the International Lifesaving Equipment Code (LSA) and the Maritime Safety Council Resolution MSC.81(70) set by the International Maritime Organization (IMO). The purpose of a lifebuoy ring is to provide buoyancy and aid in water rescue operations, ensuring the safety of individuals in emergency situations at sea.

  • Recommended to have reflective materials for enhanced visibility.
  • Water-resistant materials for buoyancy and prevention of degradation.
  • Resistant to temperature variations without compromising integrity.
  • UV-resistant coatings or materials for prolonged exposure to sunlight.
  • Constructed with corrosion-resistant materials for saltwater environments.

Product Detail

Life Preserver – Marine Lifebuoy Ring

The lifebuoy ring is designed to withstand extreme temperatures, ensuring its functionality and integrity in challenging conditions. As a life preserver, it is engineered to be resistant to high and low temperatures, preventing issues such as shrinkage, rupture, expansion, or decomposition that could compromise its effectiveness.

To enhance identification and traceability, each lifebuoy is required to be printed with the name of the vessel and the port of registration. These markings are typically displayed in capital Roman letters, providing clear and visible identification for easy recognition and association with the corresponding vessel.

In addition to the vessel identification markings, it is recommended to post reflective materials on the lifebuoy ring at strategic locations that facilitate detection. These reflective materials enhance visibility, especially during low-light or nighttime situations, aiding in the swift identification and retrieval of marine safety equipment.

By meeting these specifications, the lifebuoy ring ensures its effectiveness as marine safety equipment, capable of withstanding temperature variations, providing vessel identification, and enhancing visibility for efficient rescue operations at sea.

Marine Lifebuoy Ring Features

  • Water Resistance: The Lifebuoy ring is designed to be highly water-resistant. They are made from materials such as cork, foam, or other lightweight substances that are capable of providing buoyancy even when exposed to water for extended periods. The materials used are also chosen to resist water absorption and prevent degradation.
  • Temperature Extremes: Marine environments can experience a wide range of temperatures, from extreme cold to intense heat. Lifebuoy rings are designed to be resistant to temperature variations without compromising their structural integrity. They should not shrink, rupture, expand, or decompose when exposed to high or low temperatures.
  • UV Resistance: Continuous exposure to sunlight and UV radiation can cause degradation of materials over time. Lifebuoy rings are often treated with UV-resistant coatings or made from materials that can withstand prolonged exposure to UV rays without significant deterioration.
  • Saltwater Resistance: Saltwater is highly corrosive and can cause damage to materials and equipment. Marine lifebuoy rings are constructed using corrosion-resistant materials, ensuring their longevity and effectiveness in saltwater environments.
  • Impact and Abrasion Resistance: This life preserver encounters rough handling, impacts, and abrasion during use or storage. They are designed to withstand such conditions and maintain their functionality without compromising their buoyancy or structural integrity.
  • Visibility: Marine lifebuoy rings are typically brightly colored, such as orange or yellow, to enhance visibility in the water. This high-visibility coloring helps rescuers locate and identify the life-saving equipment more easily, even in challenging environmental conditions.

How To Choose Lifebuoy Ring?

When choosing a lifebuoy ring, the weight of the ring is an important consideration. The weight of this life preserver is typically indicated in kilograms and refers to its buoyancy or ability to support the weight of a person in the water. Here are some factors to consider when selecting between a 2.5kg and 4.3kg lifebuoy ring:

  • Expected Weight to Support: Consider the average weight of the individuals who will potentially use the lifebuoy ring. A 2.5kg lifebuoy ring is generally suitable for supporting children or individuals with a smaller body weight. A 4.3kg lifebuoy ring offers increased buoyancy and is appropriate for supporting larger adults or individuals with extra gear or clothing.
  • Intended Use: Determine the intended use of the lifebuoy ring. If it will primarily be used in calm waters or swimming pools where assistance can arrive quickly, a 2.5kg ring may be sufficient. However, if it will be used in open water or areas with strong currents, a 4.3kg ring may provide an extra margin of safety and support.
  • Consider Ergonomics and Handling: Keep in mind the ease of handling and throwing the lifebuoy ring. A heavier life preserver may require more strength to throw accurately and may be more challenging to handle in emergency situations. Consider the abilities and training of the potential users when making a choice.
