Berthing aid system (BAS) / Docking Aid System

For Safe Vessel Berthing

Modern vessels are larger, heavier and less forgiving during berthing. As a result, terminals need accurate, real-time insight to control approach speed, distance and vessel position.

The Straatman Berthing Aid System (BAS), also known as a Docking Aid System, supports safe and controlled vessel berthing at jetties and terminals. The system provides clear, real-time data to operators, enabling timely decisions and reducing berthing risk.

What Is a Berthing Aid System?

A Berthing Aid System is a shore-based system that monitors the position and movement of an approaching vessel during berthing. Using laser-based measurement technology, the system continuously measures the distance between the vessel and the jetty.

Operators use this information to control the berthing process and respond immediately when conditions change. In practice, the system reduces uncertainty during the final berthing phase and supports safer vessel positioning.

How Does the Berthing Aid System Work?

The Straatman Berthing Aid System uses laser sensors to continuously measure the distance between the vessel hull and the jetty. The system processes this data in real time and presents it clearly to operators at the jetty and in the control room. As a result, operators can monitor the berthing process closely and intervene immediately when required.

All measurements appear on large LED displays at the jetty and on standard operator screens. Straatman supplies the LED display technology through our affiliated company FactoryLab, ensuring clear and reliable visual feedback in all operating conditions.

How Does the Berthing Aid System Support Operations?

In addition to distance measurement, the Berthing Aid System supports safe and efficient daily operations through integrated functionality.

Optional system features include wireless tablet communication, pager systems and integration with terminal control environments. These tools help operators follow their preferred operational workflow and maintain situational awareness during berthing.

All system components work together as one integrated solution. This makes the system suitable for different terminal layouts and varying environmental conditions. As a result, both the Berthing Aid System and the Docking Aid System provide consistent and reliable operational support.

Key Measurement Parameters

The Berthing Aid System monitors the key parameters that influence safe vessel berthing, including:

Distance between the vessel and the jetty
Approach speed
Bow and aft position
Vessel angle during approach

Operators use this real-time data to maintain control throughout the berthing process and reduce the risk of contact damage.

Features of the lasers

Straatman designs the laser sensors for continuous operation in demanding marine environments. Key features include:

High-accuracy, maintenance-free laser sensors
Measurement range from 0 to 300 metres
Rail mounting options for flexible installation
Measurement accuracy of ± 2 cm
Suitability for Zone 1 and Zone 2 applications
Reliable operation in all weather conditions

System Configuration and Display Options

Straatman configures each Berthing Aid System to match the terminal layout and operational requirements.

Available configuration options include:

Large LED displays visible up to 300 metres (daytime)
PC- or PLC-controlled display systems
Compact display dimensions (2500 × 1200 × 200 mm)
LED-based technology for high visibility
Cost-effective solutions for hazardous areas

The system integrates easily into existing terminal infrastructure and control systems.

Designed for Terminal and Jetty Operations

Straatman designs the Berthing Aid System specifically for use at:

Oil and gas terminals
Chemical and liquid bulk terminals
LNG terminals
Container terminals
General cargo and offshore jetties

Each system supports safe berthing under real operational conditions, including limited visibility, high traffic density and changing weather.

FREQUENTLY ASKED QUESTIONS

What is a Berthing Aid System?

A Berthing Aid System is a shore-based system that supports safe vessel berthing at jetties and terminals. The system provides real-time information about vessel distance, approach speed and position during the final berthing phase.

Operators use this information to control vessel approach and reduce the risk of contact damage to the vessel, quay and fender system.

Is a Berthing Aid System also called a Docking Aid System?

Yes. The terms Berthing Aid System and Docking Aid System refer to the same type of solution. Both describe systems that support safe vessel approach and positioning at a jetty.

In practice, terminals use these terms interchangeably, depending on local terminology or project documentation. Straatman supports both definitions and delivers systems that meet the operational intent behind each term.

Why is a Berthing Aid System used?

Terminals use a Berthing Aid System to improve safety and control during vessel berthing. The system reduces uncertainty during the final approach by providing clear and reliable real-time data.

As a result, operators can prevent damage to vessels, quay structures and fenders while maintaining safe and efficient berthing operations.

How does a Berthing Aid System work?

The system uses sensors installed at the jetty to continuously measure the movement of an approaching vessel. The system processes this data in real time and displays it clearly to operators at the jetty and in the control room.

This allows operators to follow the berthing process closely and respond immediately when conditions change.

What information does a Berthing Aid System provide?

Depending on the configuration, a Berthing Aid System provides real-time information such as:
– Distance between vessel and quay
– Approach speed
– Angle of approach
– Bow and aft position

Operators use this data to manage the berthing process in a controlled and predictable manner.
