At Ship Care Service, we supply Fanbeam Laser Radar 4.2 Dynamic Positioning Systems, including new, professionally reconditioned, and exchange units, along with genuine spare parts, repair services, commissioning support, and worldwide technical assistance for offshore and marine operators.

What is the Fanbeam Laser Radar 4.2 Dynamic Positioning System?

The Fanbeam Laser Radar 4.2 is a laser positioning sensor used as a Position Reference System (PRS) within a Dynamic Positioning (DP) system. It continuously measures the distance and bearing between the vessel and strategically placed reflective targets, supplying accurate positioning data to the vessel's DP controller.

Unlike GPS-based reference systems, the Fanbeam system performs exceptionally well in offshore environments where precise relative positioning is essential for safe operations close to fixed structures.

Why is the Fanbeam Laser Radar 4.2 Important?

Accurate vessel positioning is critical during offshore operations where even minor position deviations can create significant safety risks.

The Fanbeam Laser Radar 4.2 helps operators:

• Maintain accurate vessel position

• Improve Dynamic Positioning performance

• Support safe offshore operations

• Enhance positioning redundancy

• Reduce operational risks

• Improve station-keeping accuracy

• Support offshore construction and maintenance activities

How the Fanbeam Laser Radar 4.2 Works

The Fanbeam system measures vessel position using laser technology.

Step 1 – Laser Transmission

The radar emits a low-divergence laser beam toward a reflective target installed on the offshore structure.

Step 2 – Target Detection

The laser beam reflects from the passive target and returns to the Fanbeam sensor.

Step 3 – Distance & Bearing Calculation

The system calculates the precise:

• Distance

• Bearing

• Relative vessel position

using advanced laser measurement technology.

Step 4 – Data Transmission

The calculated position reference data is transmitted directly to the vessel's Dynamic Positioning (DP) system, allowing continuous position corrections and stable station keeping.

Technical Overview

The Fanbeam Laser Radar 4.2 Dynamic Positioning (DP) System by MDL is a high-performance laser-based Position Reference System (PRS) developed for offshore vessels operating with Dynamic Positioning (DP) systems. It provides continuous and highly accurate relative position, distance, and bearing measurements between the vessel and passive reflective targets installed on offshore platforms, FPSOs, rigs, jetties, and other fixed structures.

The system uses advanced laser ranging technology to deliver real-time positioning data directly to the vessel's Dynamic Positioning controller. This enables the DP system to maintain precise station keeping during offshore drilling, subsea construction, platform supply, diving support, and marine construction operations.

Designed for demanding offshore environments, the Fanbeam Laser Radar 4.2 offers reliable performance, fast data updates, and seamless integration with major DP systems. It is available as new, professionally reconditioned, and exchange units, providing flexible solutions for vessel owners and operators.

Note: Technical specifications such as operating range, communication interfaces, update rate, and environmental ratings may vary depending on the system version, software revision, and vessel configuration. Always verify specifications using the equipment nameplate and official manufacturer documentation.

Main Components

The Fanbeam Laser Radar 4.2 consists of several key components that work together to provide accurate vessel positioning.

Laser Scanner Unit

The laser scanner emits and receives the laser beam used to measure the distance and bearing to the reflective target.

Functions include:

• Laser transmission

• Target acquisition

• Distance measurement

• Bearing calculation

• Continuous target tracking

Optical System

The optical assembly focuses the outgoing laser beam and accurately receives reflected signals from the passive prism target.

Position Processing Electronics

The internal processing unit calculates:

• Relative vessel position

• Distance

• Bearing

• Tracking information

and converts the measurements into data suitable for the Dynamic Positioning system.

Communication Interface

The communication module transfers positioning data to the vessel's DP controller, ensuring continuous station-keeping updates.

Mounting Assembly

The marine-grade mounting arrangement provides secure installation while allowing accurate alignment of the laser scanner toward the target.

Passive Reflective Target

The system operates with passive reflector targets mounted on offshore structures.

These reflectors:

• Require no external power

• Have minimal maintenance requirements

• Provide reliable laser reflection for accurate tracking

Working Principle

The Fanbeam Laser Radar 4.2 continuously determines the vessel's position relative to a fixed offshore structure.

Step 1 – Target Alignment

The laser scanner is aligned with a passive reflective target installed on the offshore structure.

Step 2 – Laser Transmission

A focused laser beam is transmitted toward the reflector.

Step 3 – Reflection

The reflector returns the laser beam back to the scanner.

Step 4 – Distance Calculation

The system calculates the precise distance between the vessel and the reflector using laser measurement technology.

Step 5 – Bearing Measurement

Simultaneously, the scanner determines the bearing angle to the target.

Step 6 – Position Reference Output

The calculated distance and bearing are transmitted continuously to the Dynamic Positioning controller, allowing automatic vessel position correction.
