Capstans
As an integral part of your quick release mooring hooks or separate custom-made capstans
The Straatman Berthing Aid System (BAS), also referred to as the Docking Aid System, supports safe and controlled berthing operations at jetties and terminals. The system uses advanced laser and LED technology to measure the distance between the jetty and an approaching vessel in real time.
In addition, the Berthing Aid System monitors key parameters such as bow and aft distance, approach speed, and vessel angle. Operators can view this information on a standard PC or on a large LED display installed at the jetty. Moreover, the Berthing Aid System can display additional operational data, including wind speed, current, and wave conditions. As a result, operators gain clear insight during berthing and can make timely, well-informed decisions to ensure safe mooring.
The laser system measures the distance between the jetty and the side of an approaching vessel in real time. Therefore, operators can monitor the berthing process accurately. The system displays these measurements clearly on a screen mounted on the jetty as well as in the control room. In addition, the LED display technology comes from our affiliated company, FactoryLab.
In addition, the system offers several optional features, including wireless tablet communication and advanced pager systems. This allows operators to adapt the system to different operational preferences. By bringing all system expertise together in one integrated setup, we create a high degree of flexibility. This means the Berthing Aid System and Docking Aid System suit different terminal layouts and operating conditions.


Our Berthing Aid Systems are available with a wide range of options, including:


A Berthing Aid System is a safety system that supports vessels during berthing.
It provides real-time information about distance and speed while a vessel approaches the quay.
yes. Different terms are used for the same solution. For example, Berthing Aid System, Docking Aid System, and Berthing Approach System all refer to systems that support safe vessel approach and berthing.
The system improves safety during berthing operations. It helps prevent damage to the vessel, quay and fenders by giving the crew clear and reliable approach data.
Depending on the configuration, the system can show:
. Distance to the quay
. Approach speed
. Angle of approach
First, sensors installed on the quay or on the vessel measure the vessel’s movement. Next, the system processes this data and displays it in real time on the operator’s screen.
Berthing Aid Systems are commonly used by:
. Ports and terminals
. Offshore terminals
. Ferry terminals
. LNG and tanker berths
. Harbor authorities
Berthing Aid Systems are indeed used for large vessels. For example, they support the berthing of tankers, container vessels, and offshore units, as well as smaller ship types.
Yes. The system can be configured based on berth layout, vessel type and operational requirements.
Sensors are typically installed:
. On the quay wall
. On dolphins
. On fender systems
. The exact layout depends on the berth design.
Primarily, yes. The system is designed to support the approach and berthing phase, when risks are highest.
No. The system supports decision-making but does not replace the experience of pilots or crew.
Yes. Our Straatman Berthing Aid Systems are designed for marine environments and operate in harsh weather conditions.
Yes. Integration with port management or monitoring systems is possible, depending on the setup.
Key benefits include:
. Improved berthing safety
. Reduced risk of damage
. Better situational awareness
. More controlled berthing operations
Yes. Our Berthing Aid Systems will be supplied in line with applicable international and industry standards.
Basic training is recommended. The system is designed to be intuitive and easy to understand for operators.
Important factors include:
– Type of vessels using the berth
– Berth geometry
– Environmental conditions
– Required data and display options
