Delivering challenging subsea solutions from concept to completion, MacArtney specialises in the design and manufacture of offshore cable handling systems for the renewable energy industry, in particular the offshore wind sector.

The CEMAC offshore power quadrants represent MacArtney’s leading-edge offshore cable handling equipment. These power quadrants belong to the CEMAC product line incorporating both cable carousels, linear cable engines and track tensioners.

Being electrically driven, the CEMAC offshore power quadrants are robust and energy-efficient systems that safely control the installation and recovery of offshore power and telecom cables.

The CEMAC power quadrants feature durability, high performance, and easy integratability. Available in standard and custom configurations, they are easily combined with cable carousels, track tensioners, spooling arms, etc.

The CEMAC design represents compact and modular systems being easily mobilised and cost-effective in terms of transport. All main components are standardised, which facilitates adaptation and upgrading to the required performance and capacity.

The MacArtney power quadrants are fully synchronisable with all MacArtney CEMAC offshore cable handling equipment. The power quadrants are also compliant with third-party equipment. This enables integration into existing and rental cable equipment lay-lines.

The CEMAC power quadrants are available with a remote diagnostics tool which enables MacArtney technicians to remotely monitor and supervise in real time. By eliminating unnecessary offshore engineering support, this unique feature generates substantial cost-savings to owners and operators.

Customised solutions

The CEMAC offshore power quadrants come in 1-, 2-, and 3-pair versions and are available for combined operation.
