Specialised motors for subsea cable-laying vessel
This marks Rotor's second collaboration on a vessel of this type, reinforcing its reputation as a trusted partner in the marine industry.
Currently in production, the vessel is designed to transport, store and lay subsea cables for renewable energy infrastructure. The motors supplied by Rotor play a key role in ensuring the reliable operation of equipment such as carousels, tensioners, and capstans used to handle and deploy the cables. These cables, weighing thousands of tonnes, must be laid precisely and continuously while the vessel is in motion.
The project involved the supply of 54 highly specialised motors, ranging from 15.6kW to 87kW and with frame sizes from 132 to 315. Each motor was meticulously designed to meet the specific demands of the subsea cable-laying vessel.
Each motor needs to operate reliably in harsh marine environments, meeting stringent technical requirements. The motors feature special cooling systems, marine coatings, IP67-rated brakes and encoders, ensuring robust performance even in challenging sea conditions. Additionally, all motors received DNV certification, a key standard in the marine industry.
A critical aspect of this project was the motors' ability to continue operating even in the event of a drive failure, ensuring uninterrupted speed and load handling during subsea operations. Rotor's engineering team worked closely with Remacut's engineers in both the UK and Italy to meet these demands, resulting in a custom solution tailored to the vessel's needs.
