ETD 100/350 electric whistle, suitable for vessels with a LOA 20m till 75m.
A Strong Signal Without Noise
Many who navigate under the IMO Regulations (COLREG 1972) understand the importance of sound pressure levels for efficient signaling. However, the rules also state that “the sound pressure level of the vessel’s own signal at the listening posts shall not exceed 110 dBA and, as far as practicable, should not exceed 100 dBA.” This creates a challenge: how can a vessel emit a strong signal without producing excessive noise onboard?
Solving the Paradox
The common solution to this dilemma is placing the whistle high above deck. But what if even the highest point isn’t high enough? The answer lies in a whistle with unsymmetrical sound distribution. This innovative design offers several benefits:
- Focused Sound Radiation: The total sound is directed towards the horizontal plane, reducing downward (and upward) noise by up to 10 dBA.
- Even Sound Distribution: The sound spreads appropriately in all horizontal directions, ensuring compliance with the headline sound pressure levels prescribed by IMO.
- Optimized Sound Spectrum: This specially designed sound spectrum ensures high electro-acoustic efficiency and rich “tone color,” making the signal more perceptible in noisy environments.
- Durable Design: The horn uses twin-unit electrodynamic drivers protected by non-metallic, glass-fiber reinforced polyester, ensuring durability and long-term performance.
These advancements come together in the TYFON ETD 100/350, a new horn with a vertically extended front that tackles the issue of excessive onboard noise.
Additionally, when a “combined system” of two whistles, as described by the IMO, is employed, an even more effective and significant tone spectrum is produced. An air-driven TYFON for 260 or 440 Hz adds further reliability and top-notch performance.

LEVELMASTER® WIM – Water Ingress Monitoring
SOLAS XII/12 Compliance for Bulk Carriers
For over 30 years, Kockum Sonics has delivered reliable marine level technology through its LEVELMASTER® system. In response to SOLAS XII/12 regulations, we introduced the LEVELMASTER WIM (Water Ingress Monitoring) solution. Based on the well-established LEVELMASTER® CALM system, WIM uses accurate electro-pneumatic measurement, eliminating the need for electrical components in the holds. This design reduces both installation and operational costs significantly. Furthermore, the system is type-approved by leading classification societies such as DNV, LRS, ABS, and BV.
Key Features and Benefits
Each hold, tank, or compartment connects to a central LEVELMASTER® CALM cabinet using a single sensing pipe. The cabinet houses all electrical components and hydrostatic sensors, eliminating the need for costly zener barriers or cable junction boxes. Sensing lines are made of durable polyamide tubing or optional stainless steel, making them cost-effective and easy to install.
The system automatically self-calibrates every 24 hours to ensure consistent accuracy. In case of solid ingress into the tube, an automatic air purge function activates. Importantly, there are no electrical sensors in the cargo holds, only a simple sensing tube. Additionally, the system can convert any sounding pipe into a sensing tube with a special valve unit adapter, while air consumption remains minimal.
Continuous Level Measurement and Alarms
The LEVELMASTER WIM provides real-time level information, helping the Master determine whether an alarm is an actual scenario or a false alarm. Unlike limit switch systems, which might only indicate 500mm of water in the hold, WIM can show whether the water level has reached a critical depth, such as 1900mm.
The DU350 WIM alarm panel complies with IMO specifications and can be either console or bulkhead mounted. We also offer serial outputs to interface with ship stability and cargo planning software like LOADMASTER®.

As a result, we have established a reference list of over 12,000 deliveries. Our clientele includes some of the world’s largest container and car carrier owners.
User-Friendly Interface
Today, the Kockumation loading programs feature an interface that stands out for its user-friendliness. We designed it to be simple enough for inexperienced users while still offering a comprehensive range of powerful features for seasoned professionals. With a Kockumation loading program, you gain access to the most powerful and versatile cargo planning and stability applications available.
Compliance and Cargo Planning in One
Every LOADMASTER, LOADSTAR, and EASEACON delivered includes a core base module packed with calculative tools. These tools fulfill the mandatory stability and stress requirements imposed by maritime authorities. Thus, even though we call it the ‘Base’ module, ship owners, yards, and technical managers can trust that our programs ensure compliance and best practices without diverting critical resources.
Moreover, the base module offers flexibility to incorporate additional ship-specific tools. For instance, bulk carriers benefit from automatic checks against flooded holds in compliance with regulations. This capability further enhances the utility of our programs, ensuring you have everything needed for effective cargo planning and stability management in one solution. With Kockum Sonics, you receive unparalleled support in navigating the complexities of maritime operations.

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.
