Offshore wind energy
MacGregor has designed and built solutions for the oil & gas industry for many years, with a strong history of innovation in the development of mooring systems for floating production units and semi submersible drilling rigs.
Our extensive experience in this demanding sector, transfer of proven technologies and the development of automated solutions are supporting the progression of wind energy with a continuing focus on safety, reliability and optimum performance.
Motion-compensated pile gripper
Combined expertise reduces monopile installation time and increases operability.
A new monopile installation solution, jointly developed by MacGregor and Kongsberg Maritime, incorporates latest automation capabilities to eliminate unnecessary mooring and offer significant time and cost savings to the offshore wind energy market.
The new pile gripper range enables a step change to be made in the logistics of bringing multiple monopiles to the field and, through the application of motion-compensation technology coupled with dynamic positioning, reduces the time taken for each installation.
Significant improvements in the operability, productivity and efficiency of future generations of monopile installation vessel fleets are provided by the pile gripper solution.
The solution has three main functions
- Monopile logistics on deck
- Lifting and skidding monopiles on deck and up-ending system
- Motion-compensated pile gripper
- Dampening out wave forces during lowering
- Keeping monopile in a precise vertical position when being driven down into the seabed
- Guidance control system that works in tandem with the high-precision DP system to provide a coordinated link between the pile gripper and DP system
Developed through the combination of MacGregor’s technology for advanced heave compensated offshore cranes, 40 years’ experience in building safety-critical control systems for offshore equipment and recent focus on advanced robotics and simulations.
MacGregor’s all-electric gangways are designed for high performance with active motion compensation and increased automation.
The Horizon range consists of five distinct models, all developed around the same all-electric architecture and using proven technology but configured in a new way.
- All-electric, motion compensated walk-to-work gangway
- Fully enclosed transfer bridge with industry leading internal clear width
- Optional integrated personnel and goods elevator
- Fully customisable foundations for optimal vessel integration
- Low weight, high performance and increased automation
- Full integration with AROS operator station
The Colibri 3D motion compensated offshore crane combines our proven capabilities in crane design and manufacturing with innovative motion technology and analysis. All Colibri cranes are based on a range of cylinder luffing cranes designed for long service life in harsh North Sea conditions.
Logistics support capability is increased by enabling a single operator to seamlessly change between the crane and gangway operation from a centralised control station.
- 3D and wind load compensation
- Unique anti-sway technology
- Lightweight, high performance system
- Structure detection & anti-collision
- Side and off-lead detection
- Independent main winch from 1T to 50T
- Full integration with gangway operator station
Floating wind energy installations
MacGregor’s range of mooring system solutions for the offshore floating wind market is based on proven technology and decades of experience in the design and build of mooring solutions for the demanding oil & gas industry.
Our solutions enable safe, reliable and effective performance by adopting a systems level approach, with sufficient flexibility to meet the requirements of different floating installations.
- Mooring systems with connectors and tensioners that can be used in any water depth, from shallow to deep water
- In-line tensioning allows for simple initial tensioning with the ability to re-tension mooring lines if required in the future and allows for optimised layout and flexibility with respect to anchor types needed to suit the seabed conditions
- Bottom-fixed tensioner allows for subsea tensioning without introducing a clump weight in the mooring line design
- Fairlead chain stoppers and pull-through connectors greatly simplify turbine installation and enable easy disconnection of mooring lines from the platform when needed to do so for maintenance requirements
