Our Offshore DP Tagline System is ideal for a wide range of lifting operations, including:
Our standard solutions for offshore projects cover a range from 20-150kN , covering the vast majority of lifting operations within this span.
However, we understand that some projects require more specialized approaches. If your requirements go beyond our standard offerings, we are always ready to assist with our tailored concept solutions.
The offshore DP tagline system can be used as either direct line or in V-shape setup.
There are also different vessel interface solutions depending on vessel layout, and what the system is to be used for. The system can either be deck-mounted with a weld-on interface, pedestal mounted with the system hanging from the pedestal, in existing pad eyes or on flages, it can be mounted on top of the pedestal on existing brackets, or in the boom.
We recommend mounting the system on the pedestal or on deck, to ensure easy access to the winches and electrical cabinets in all cases, to avoid bringing the boom in rest in case of troubleshooting or servicing.
Manual mode
Manual mode is available by joystick and can be used to operate the winches individually. Manual mode is used for rigging and de-rigging of the system.
Dynamic Position Mode (Auto)
In Auto Mode, both winches work together to maintain the load’s position reference, ensuring a stable, non-rotating load.
Dynamic movements are compensated by directing torque to the winch experiencing the highest load.
If rotation is required, it is easily initiated by adjusting the position setpoint using the joystick.
Follow mode
In Follow Mode, both winches work together to maintain the position reference, ensuring a stable, non-rotating load with high precision – even for loads as light as 1,500 kg.
The system automatically follows load movements, such as when booming up or down.
Dynamic movements are compensated by directing torque to the winch experiencing the highest load.
If rotation is required, it is easily initiated by adjusting the position setpoint using the joystick.
Adaptive Tension DP mode (Option)
In AT/DP mode, the DP software is running subsequently.
Once the load is in the correct position, AT/DP mode is activated.
This engages full torque at zero speed, allowing the winches to maintain position at activation/existing load, up to full capacity.
If the system capacity is overloaded, the winches will pay out at minimum speed.
During Adaptive tension mode, the operator manually controls the load by joystick.
The joystick adjusts the speed setpoint, activating pay in/pay out of the winches.
The HARCO DP Tagline System for offshore operations is developed with a clear ambition: to deliver extreme precision and maximum availability in challenging offshore environments.
So, how have we made that possible?
We’ve gone beyond standard solutions, carefully engineering every component to ensure optimal performance under the most demanding conditions. From innovative lubrication systems to advanced surface treatments on wear components, each part of our system is designed for durability and reliability.
However, we know that seamless operation requires more than just strong physical components. That’s why we’ve developed industry-leading software that enhances smoother operation and ensures extreme precision in lifting scenarios.
Adapt the system by choosing from a variety of options.
By adding options, you can adapt the system to meet the specifik challenges and needs of your project.
From long-range antennas to automatic grease systems – there are plenty of options available, and we will of course assist you in finding the best solutions.

V-shape configuration
The onshore DP tagline system can be operated in V-shape configuration, where the system is mounted either in the bottom of the boom, or on the crane ballast with the wire routed through two guide pulleys in the bottom of the boom. The wires are then connected to the yoke through a snatch block, and goes up to the top of the boom.
With the V-shape setup, you get great control similar to a traverse system, in top and bottom position. With the wires connected to the top of the boom at installation height, you achieve almost the same control as you would have with a traverse system, slightly less control in the middle due to geometry, and good control in the bottom when picking up the load.
The V-shape setup is super fast to mobilize, and requires minimal crane interface, due to only requiring a lower interface, and a top connection point which is usually integrated in the crane. The V-shape system provides horizontal and vertical control at installation height, due to the horizontal line from the top attachment and the near vertical line from the winches. Due to the loop configuration, the V-shape setup operates at reduced speed.
Direct line configuration
The onshore DP tagline system can be operated in direct line configuration, where the system is mounted either on a ballast interface, or on a self-propelled Maverick interface. The interface is to be placed on the ground in a suitable position, ensuring a straight line for installation. The direct line configuration provides the control known from most on-shore installations, with an angled tagline connection ensuring good control of the load, but with slightly reduced rotation control compared to the V-shape and single line setup.
Single line configuration
Single line configuration is one of our new on-shore tagline system concepts. It introduces one guide wire winch, and a custom made snatch block.
The single line configuration consists of:
The single line configuration is simple to mobilize, as it only requires one guide wire to be routed from the winch to the top of the boom, and two tag wires to be routed through the snatch block to the top of the boom.
The configuration allows for adjusting guide wire elongation, ensuring the best possible control of the lifted load in all scenarios. With this setup, only longitudinal force is applied to the crane boom.
The single line configuration ensures high control during lifting operations in all scenarios, as it gives horizontal control due to the snatch block following the lifted load all the way from pick-up to installation height.
While onshore conditions may not be as demanding as those offshore, our onshore tagline systems still deliver exceptional precision, high availability, and outstanding efficiency.
With just one operator controlling two automatic tagline systems, you’ll require fewer resources while performing operations safer, quicker, and more efficiently – maximizing uptime and overall availability.
Our onshore DP tagline systems are cost-effective and specifically designed for onshore use, making them smaller, more compact, and easier to transport.

When you need an easy solution for difficult terrain.
Operating onshore presents different challenges compared to offshore, and transporting tagline systems across difficult terrain is one of them. But we believe it shouldn’t have to be so hard. That’s why we created Maverick.
Maverick is our Onshore DP Tagline System, mounted on caterpillar tracks, designed to effortlessly transport the tagline system across challenging ground and easily position it in the correct spot. It needs no external power supply as it has a self-contained power unit for powering the tagline system.
Maverick offers the same functionality as a tagline system mounted on a ballast interface but with a much easier method of transporting the system to the operational area.
With our turn-key solutions, we take care of everything – from mobilization to operation, maintenance, and demobilization. We offer a complete package that minimizes the need for communication and alignment.
We offer all of our standard equipment as a rental solution, providing you with greater flexibility through shorter lead times and fewer concerns related to storage and maintenance.
In our in-house testing facilities we test all our winches before dispatch. By simulating realistic conditions, we deliver true plug-and-play winches – reducing mobilization time significantly.
The Compensated Tagline System is the ultimate choice for floating operations, offering unmatched stability and control in extreme conditions.
