Pre-COLREG 1972 Sound Practices
Before the introduction of COLREG 1972, smaller vessels often used low-pitched tones, which were typically reserved for larger ships. This practice was not as strict as required. However, modern IMO regulations ensure that very low tones are exclusively used by the largest vessels, while medium and smaller vessels have more flexibility in frequency selection. Vessel LOA > 200mWhistle Options for Large Vessel LOA > 200m
Kockum Sonics offers specialized whistles for vessels 200 meters or longer. The ELECTRO–TYFON® MTX 150/130, an electrically driven piston whistle, features minimal moving parts and a unique design that reduces deck noise by 6–8 dB. Additionally, air-driven whistles like the MKT 150/110 and MKT 150/90 meet IMO standards for large ships, delivering powerful sound performance.Contact Us for More Information

MKT 150/110 air whistle, suitable for vessels with a LOA > 200m
Regulations Before and After COLREG 1972
Before “COLREG 1972” (International Regulations for Preventing Collisions at Sea), low-pitched tones were often used for smaller vessels. However, the principle of reserving low tones for large vessels was not strictly enforced. The IMO regulations now reserve very low tones exclusively for the largest ships. For middle-sized and smaller vessels, there are broader frequency options available.
Signal Preferences and Frequency Range
IMO regulations prioritize signals that maintain audibility even at a distance. Vessels over 200 meters (656 feet) should use whistles with frequencies of 130 Hz or lower. These frequencies ensure effective communication and compliance with maritime safety standards.
Installation Instructions for MKT 150/110
Mounting the MKT 150/110
Secure the MKT 150/110 whistle with four M12 bolts to an outrigger or similar construction. Ensure the structure is stable to prevent any operational issues.
Cleaning the Supply Pipe
Before connecting the supply pipe to the whistle, blow the pipe thoroughly clean. This step is crucial to avoid any functional troubles caused by debris or contaminants in the pipe.
Installing a Primary Filter
If the pipeline above deck exceeds 100 meters (328 feet), install a primary FILTER TP 15/2 at the base of the mast. This filter protects the whistle from water condensate and rust particles, ensuring reliable operation.
Maintaining the Filter
Regular maintenance is essential for ensuring optimal performance. To begin with, it is recommended to drain the filter approximately once a month. By doing so, you can effectively prevent blockages while also maintaining the integrity of the signaling system.

MTX 150/130 electrically driven piston whistle, suitable for vessels with a LOA >200m.
General Information
The ELECTRO–TYFON® MTX 150/130 ship whistle is electrically driven piston designed for large commercial vessels with LOA above 200 meters. It delivers powerful, regulation-compliant sound signaling while maintaining low noise levels at onboard listening positions. It features minimal moving parts, a “swinging piston,” a cylinder that requires no lubrication, and an oil-free gearbox.
Key Features
- Unsymmetrical Sound Distribution: The design ensures the sound is distributed unevenly for efficient signaling.
- Adaptability: It operates effectively in all temperatures without additional measures.
- Stability: The whistle remains unaffected by voltage and frequency fluctuations.
- Maintenance-Free: The whistle is oil-free, non-corrosive, and requires no maintenance.
- Easy Installation: Simplified installation process.
- Compliance: Fully complies with International Regulations IMO 1972.
Consistent Performance in All Climate Conditions
The MTX 150/130 ship whistle performs reliably in arctic, tropical, and high-humidity environments without additional heating or cooling systems. Thanks to its patented rectangular horn and adaptive motor control, the whistle automatically adjusts motor speed to the horn’s acoustic resonance. Therefore, it maintains consistent sound output regardless of ambient temperature, voltage, or frequency fluctuations—an advantage over many alternative electric and pneumatic ship whistles.
IMO-Compliant Sound Distribution and Easy Installation
To meet IMO 1972 sound signaling regulations, the MTX 150/130 features unsymmetrical sound distribution. This design delivers the required Sound Pressure Level for navigation while keeping noise at listening posts below 110 dBA. Furthermore, the electrically driven configuration allows fast and straightforward installation, even where compressed air systems are impractical. Compared to competing marine whistles, this results in quieter onboard environments and easier retrofitting.

General Information
To ensure safety, the TK80 contactor unit includes a thermal overload relay that protects the installation from excessive current. This relay has a set point of 13A, providing reliable protection during operation. By default, the relay operates with an automatic reset feature (A), which simplifies management for users. However, operators can change the relay function to a manual reset option (H). In this case, the user must reset the overprotection using the green pushbutton, adding an extra layer of control.
Additional Features
Moreover, the unit supplies heating voltage to the ELECTRO-TYFON®. This heating voltage automatically switches off during signaling, optimizing energy efficiency and enhancing safety. As a result, operators can count on the system for consistent performance and protection under various conditions. Overall, these features make the contactor unit a vital component in ensuring reliable and safe operation.
