Anchor engine constant tension monitoring system: The guardian of ship safety

Berthing safety: A potential risk that cannot be ignored​
When a ship is at anchor, the anchor chain is like the bond of life. Excessive tension in anchor chains can lead to breakage or equipment damage, while insufficient tension can cause ships to drift, collide with the wharf, other vessels or obstacles, resulting in serious safety accidents and economic losses. The traditional method that relies on manual observation and manual adjustment of the anchor machine often lags behind and is inadequate when facing constantly changing waves and tides, with risks and hidden dangers always present.

​Constant tension system: The core solution for ship anchoring​
The anchor machine constant tension monitoring system is precisely an intelligent solution developed to address this pain point. It is a high-tech system installed on the anchor machine of ships. Its core mission is to monitor the actual tension on the anchor chain in real time and automatically control the movement of the anchor to keep this tension within the preset "safe constant value" range. This system ingeniously integrates three major capabilities: precise sensing, high-speed computing and intelligent control, and is a key piece of equipment for ensuring the safe berthing of modern ships.

​System working principle: Precise monitoring, real-time response, and automatic adjustment​

1. ​High-precision real-time perceptionThe core lies in the high-performance tension sensors deployed at the key parts of the anchor chain. These "electronic senses" constantly perceive the subtle changes in the tension of the anchor chain and precisely convert the physical tension into electrical signals.
2. ​High-speed data processing and analysisThe sensor signals are rapidly transmitted to the "brain" of the system - the central controller unit. After receiving the data, the controller conducts real-time comparison and analysis with the pre-set safety tension threshold (commonly known as the "constant tension band").
3. ​Intelligent closed-loop controlThe controller makes decisions based on the analysis results:
   • If tensile force is detectedGreater thanWhen the safety limit is reached, the system immediately issues an instruction to drive the anchor machine to release an appropriate amount of anchor chain, actively reducing the tension.
   • If tensile force is detectedLower thanWhen the safety limit is reached, the system issues an instruction to drive the anchor machine to retract an appropriate amount of anchor chains, increasing the tension to a reasonable level. The entire process operates fully automatically without the need for human intervention.
4. ​The early warning mechanism is activated.When the detected tension approaches or exceeds the danger warning line, the system will immediately trigger a significant audible and visual alarm device to alert the crew members to pay attention at the first moment and may take emergency measures.

​The application scenarios are extensive: These ships are particularly important​
The value of this system is highlighted in various ship operation scenarios:

• ​Large ocean-going merchant ships (cargo ships, container ships, oil tankers)The tonnage is huge, and the load-bearing capacity of the anchor chain is astonishing. There can be no slightest mistake in the safety of anchoring, especially for oil tankers. Once they run off anchor, the consequences would be unimaginable.
• ​Dangerous goods carriers (chemical tankers, liquefied gas tankers)Loading special goods has extremely high requirements for berthing stability and serves as a key barrier against environmental disasters.
• ​Port operation vessels (tugboats, pilot vessels)Frequent anchoring operations and precise constant tension control are directly related to operation efficiency and collision avoidance safety.
• ​Marine engineering vessels (drilling platforms, engineering ships)Long-term operation in specific sea areas requires the ability to withstand harsh sea conditions and maintain stable positioning, which is an important link in ensuring survival.
• ​Luxury cruise ships and ro-ro shipsThe large passenger capacity and the extremely high requirements for occupant comfort and safety determine the necessity of a constant tension system.

​Core Value: Why is It a Must-have for Ships? ​​
The benefits brought by the deployment of the anchor machine constant tension monitoring system are multi-dimensional

• ​Improvement of intrinsic safetyIt significantly reduces the risk of anchor chain breakage or vessel "drifting" (accidental drift), fundamentally protecting the lives of crew members, property on board and the safety of the Marine environment, and serves as a solid defense line for accident prevention.
• ​The mooring posture is stable.The system continuously maintains an appropriate pulling force, which can significantly reduce the degree of sway of the ship in the waves. The activities of personnel on board, the loading and unloading of goods, and the operation of equipment all become more stable and reliable.
• ​Optimization of operation efficiencyThe realization of automated control in the anchoring process eliminates the burden of frequent manual adjustments for crew members, shortens the time required for precise berthing, and enhances the port's turnover efficiency.
• ​Equipment protection reduces costsTo prevent the anchor chain and anchor machine system from premature wear, fatigue or damage due to long-term excessive tension or frequent impact loads, effectively extend the service life of key equipment, and reduce the cost of maintenance and repair.
• ​Comply with legal normsIt complies with increasingly strict maritime safety regulations both at home and abroad, providing strong support for the compliant operation of ships and avoiding potential risks and penalties.

​Operation and maintenance guarantee: The reliable foundation of intelligent systems​
The ease of use and reliability of the system design are equally important, and daily maintenance is relatively simple

• ​Sensor maintenanceThe sensor probe and its surrounding environment need to be cleaned regularly to prevent oil stains, dust or seawater from forming a crust, which may affect its measurement accuracy.
• ​Calibration of key parametersCarry out tension calibration work in accordance with the manufacturer's guidance manual or the specified cycle to ensure that the system monitoring values are always accurate and reliable.
• ​Connection status checkRegularly check whether the physical line connections between sensors, controllers and various devices are firm and reliable to avoid signal interruption caused by loosening or corrosion.
• ​Software iteration and upgradePay attention to the system update notifications released by the manufacturer, upgrade the firmware or software programs in a timely manner to enhance performance, fix potential vulnerabilities or add new features.
• ​Common Fault ResponseIn case of false alarms (false alarms) or delayed responses from the system, it is usually necessary to prioritize checking the sensor status (whether it is damaged or dirty) and parameter Settings (whether the calibration values are correct).

​Future outlook: Evolving towards greater intelligence and greater connectivity​
With the rapid development of technology, the constant tension monitoring system for anchor machines is also being upgraded

• ​Intelligent prediction (Empowered by AIBy integrating real-time meteorological and sea condition data with AI algorithms, the system can predict the trend of wind and wave changes in the future, proactively adjust the tension setting value in advance, and prevent problems before they occur.
• ​Remote interconnection (IOT integrationBy uploading the anchoring status and tension data to the ship-shore integrated platform, shore-based management personnel can also grasp the safety status of vessel mooring in real time, achieving remote supervision and support.
• ​Learn optimization and adaptationThe system is expected to automatically fine-tune the optimal constant tension range by learning the anchor grasping force characteristics under different seabed substrate conditions, thereby enhancing adaptability and anchoring efficiency.
• ​Energy efficiency Optimization (Green Shipping)Under the premise of ensuring absolute safety, through more refined tension control strategies, unnecessary frequent actions of the anchor engine are reduced to achieve energy conservation and contribute to the goal of green and low-carbon shipping.
