Motor Overhaul for Cruise Ship

Rotec’s Electrical Mechanical Services division completed the overhaul of 21 ship’s motors last month for a leading leisure industry company.

The cruise ship, who carries thousands of passengers each year, voyages throughout the Baltic, Norwegian Fjords, and the Mediterranean. In regular use, our engineers had a strict time limit of 14 days to remove, overhaul and reinstate all 21 motors whilst the ship was in dry dock.

The scope of works included:

Removal and inspection

  • Safe and efficient electrical and mechanical disconnection of all 21 motors, including the port and starboard anchor winch motors.
  • Thorough inspection of all plate detail and insulation valves.

Overhaul

  • Full steam cleaning of the motors and re-varnishing as required.
  • Baking of the motors in a temperature-controlled oven to ensure proper curing of the varnish and to remove any residual moisture.
  • New bearings fitted where required.
  • Repair of worn end-shields by sleeving and machining back to tolerance.
  • Replacement of brake pad discs with excessive wear.
  • Insulation tests conducted at 500 volts to ensure electrical safety and integrity.
  • Dynamic balancing carried out to avoid unnecessary vibrations, reduce noise, prevent mechanical failure, and improve balance and efficiency.
  • Inspection of all electrical cables for damage.

Reinstallation

  • Safe and efficient reinstallation of all 21 motors back onto the ship.
  • Careful reconnection of all electrical and mechanical components.

Report

  • A detailed report, with images of all motors, was completed and a copy sent to the client upon completion.

All work was completed within the 14 day schedule deadline.

The completed overhaul will significantly improve the reliability and lifespan of the ship’s motors, reducing the risk of unexpected breakdowns and ensuring continued safe and efficient operation.

Rotec Hydraulics launches first-of-its-kind Electric Winch System

Our team at Rotec Hydraulics Ltd, experts in system solution design, have developed a pioneering electric winch system that offers a zero-emission alternative to hydraulic winches. This innovation supports customers in achieving net zero goals with enhanced performance and precision.

“This project is an example of how Rotec Hydraulics is spearheading electrification within the fluid power industry to enable decarbonisation of the hardest-to-abate industry sectors.

“The addition of Parker components, including IQAN technology, has made the challenge of producing the same, if not enhanced, performance compared to the equivalent hydraulic winch system solution possible.”

– Paul Prouse, Managing Director of Rotec Hydraulics Ltd.

Our in-house design team have innovatively designed and developed the first-of-its-kind electric winch system in response to a request from a client. The customer, a national company working within the utilities sector, has ambitious net zero goals and Rotec, as its sole winch design, supply and service provider was keen to support.

Expertise in system solution design

The ambitious R&D project was specifically dedicated to produce an electric winch with the equivalent performance and functionality of the hydraulic winch that the client currently uses on their large fleet of Isuzu D-Max vehicles.

Stepping up the design challenge

Despite other winch providers saying an electric winch system capable of proportional speed control lifting 1.5 tons and dragging 3.6 tonnes and not overheating was impossible, we are pleased to reveal our new offer to the market.

This particular example features two operational modes (lifting and pulling). The proportional speed control allows for safe, controlled ascent and descent of the winch system when lifting.

Operators have reported that the infinite winch speed control using joysticks in cab and/or remote pendant have allowed for more precise and accurate placing of the load than the previous hydraulic winch delivered.

The integrated thermal management of both motor and motor inverter along with natural air cooling of the motor inverter, means that Rotec’s electric winch system has an unlimited run time.

The electric winch system is fully customisable to any future clients looking to change to fully electric winches.

Sustainability

Our electrical winch system reduces CO2 emissions as a result of being powered by a lithium battery, rather than the vehicle’s diesel engine.  The vehicle engine does not need to be turned on in order to operate the winch, unlike its hydraulic counterpart. 

The electric winch’s carbon emissions are minimised with the only emissions being those generated when the vehicle is in motion and it is charging the winch system’s lithium battery.

Not just a supplier of parts

Winner of Manufacturer of the Year 2023 at the Somerset Business Awards, we can provide tailored winch system designs to your vehicle and operational requirements and offer design, manufacture, fitting and on-site servicing and repair service backed with consistent excellent customer service. 

Customers can customise rated line pull, line speed or rope type and capacity to optimise their operations. High quality, robust components mean all Rotec winch systems are suitable for operating in challenging environments.

Our innovative electric winch system has enabled its customer to not only cut emissions but work smarter, more accurately and increase productivity with proportional control capability and/or remote monitoring options.
