MacArtney MERMAC R electrically driven winches are robust and advanced vehicle handling systems that safely control the launch, operation and recovery of work class and inspection ROV systems.

MERMAC R winches are designed to be dependable, offer high performance and be easy to use. MERMAC R winches are available in standard and custom configurations and are easily combined with launch and recovery or moon pool handling systems. All MERMAC R winches are designed as compact and modular systems. Several components are standardised, making it easy to specify, adapt or upgrade to the required performance and capacity.

MERMAC R winches are available with active heave compensation (AHC) which immediately compensates for vessel movement caused by waves, even in heavy seas. This feature reduces weather-related downtime and makes launch and recovery of tethered equipment easier and safer.

MERMAC R winches can be delivered with a remote diagnostics tool which allows MacArtney technicians to remotely monitor and troubleshoot several winch functions in real time. By eliminating unnecessary offshore engineering support, this unique feature potentially offers substantial cost savings to customers and operators.
