Terminal assisted docking system (BAS)

for ships

Overview
The Straatman Berthing Aid System (BAS) is a shore-based docking aid that provides real-time distance, position and speed information to support safe vessel berthing at jetties and terminals. Each system is configured to match terminal layout and operational procedures.

How it works
Laser sensors continuously measure the distance between the vessel hull and the jetty. Measurements are processed in real time and presented to operators at the jetty and in the control room. Data can be shown on large LED displays installed on the jetty and on operator workstations. Straatman coordinates LED supply through an affiliated company to ensure visibility in all conditions.

Operational support and integration
The BAS integrates with terminal systems to support daily mooring operations. Optional features include wireless tablet links, pager communication and PC- or PLC-based display integration. Components are combined into an integrated solution adaptable to different terminal layouts and environmental conditions.

Key measurement parameters

• Distance between vessel and jetty
• Approach speed
• Bow and stern position
• Vessel angle during approach

Features of the laser sensors
Straatman laser sensors are engineered for continuous marine operation and easy installation. Key features include:

• High-accuracy, maintenance-free laser measurement
• Measurement range: 0 to 300 metres
• Accuracy: ± 2 cm
• Rail-mounting options for flexible installation
• Variants suitable for Zone 1 and Zone 2 hazardous areas
• Reliable performance in all weather conditions

System configuration and display options
Available options allow customization to site requirements, including:

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

Designed for terminal and jetty operations
The BAS is designed for a range of terminal types, including:

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

Benefits
The system reduces uncertainty during final approach, enabling timely decisions, lowering berthing risk and helping prevent damage to vessels, quay structures and fenders. It supports safe berthing in limited visibility, high traffic and adverse weather.
