Modular cable lay spread

Vessel availability and long mobilisation periods can delay cable installation and repair campaigns across the offshore wind sector. This modular cable lay spread is purpose-built to help operators to respond faster to cable lay and repair operations, especially under emergency conditions. 

Instead of waiting for a specific vessel to become available, the system can be installed on a wide range of vessel types, including smaller vessels, to improve response times and reduce downtime.

Key features:

• 72-hour mobilisation and commissioning
• Fully scalable and configurable for different vessel types
• Containerised components for rapid transport
• Quayside assembly to limit vessel idle days
• Adaptable for both cable repair and installation campaigns

All system components are palletised for rapid transport in standard ISO containers or flat racks and can be largely pre-assembled on the quayside to reduce vessel idle days. 

Once installed, plug-and-play operation reduces commissioning time and simplifies integration with existing deck layouts. The modular cable repair spread is self-sufficient for pull testing of the winches and the breakback tensioner, removing the need for additional test equipment. 

Flexible module positioning and multiple fastening locations also allow the cable spread to be configured around the available deck area, enabling deployment across a wider range of vessel types and sizes without redesign or permanent modification.
 

The modular system can be configured around specific project requirements, vessel availability, and deck constraints. This flexibility makes it suitable for both cable installation and repair across offshore wind projects.

Operational advantages:

• Configurable for cable lay and repair
• Flexible deck layout for efficient use of available space
• Easily scalable with extended roller highways
• Seamless integration with Royal IHC rental winches and tensioners

The palletised roller tables maintain cable alignment and integrity, while height adjustment enables operators to tailor the system directly to their requirements.

The quadrant breaks down into three transportable sections and can be handled using standard forklifts, eliminating the need for specialist cranes. 

The quadrant handling system can be transported as a single unit with no disassembly required. It mechanically interlocks during overboarding to provide secure and reliable load transfer.

The chutes are supplied in modular sections to pack into standard 40 ft containers for simplified transport. They can be articulated and secured on deck, clear of the waterline during vessel transit.

The recently upgraded 15-tonne breakback tensioner supports bi-directional cable passing and use biodegradable oil. Pull testing can be carried out against the chute grillage, further reducing commissioning time.
