Deyuan Electric Horns - Empowering Safe Navigation with Innovative Technology
Publish Time: 2026-04-28 Origin: Site
Deyuan Marine today launched a new navigation equipment product - the electric horn. According to the International Regulations for Preventing Collisions at Sea (COLREGs), vessels of 12 meters or more in length shall be equipped with a horn.
Function of the Horn: The marine horn automatically and periodically emits fog signals in compliance with international regulations, particularly during adverse weather, heavy fog, or restricted visibility. These signals communicate the vessel's information to nearby ships for effective collision avoidance. As required by the International Convention for Preventing Collisions at Sea, 1972 (COLREGs) and its amendments, the horn is mandatory equipment for all vessels and plays a vital role in ensuring navigational safety.
Advantages of the Electric Horn:
·High-quality material: Made of 304 stainless steel, offering strong corrosion resistance and high strength.
·Integrated design: Compact and easy to install, saving valuable space.
·Energy-efficient: Power is consumed only during operation, achieving over 70% energy savings.
·Full class certification: ABS, CCS, LR, DNV approved.
·IMO compliant for international maritime safety standards.
Relationship Between Whistle Sound Intensity, Audibility Range, and Vessel Length:
Length of Vessel (L) | Minimum Sound Pressure Level at 1 metre (dB) | Minimum Audibility Range (nautical miles) |
L ≥ 200m | 143 | 2.0 |
75m ≤ L < 200m | 138 | 1.5 |
20m ≤ L < 75m | 130 | 1 |
L < 20m | 120 / 115 / 111* | 0.5 |
