Rotec Delivers Critical Engineering Solutions for Cruise Ship

Rotec, a leading provider of hydraulic, pneumatic, and electro-mechanical solutions, is proud to announce the successful completion of critical engineering works on a cruise ship at Falmouth Dry Dock. This project follows a successful dry-docking of a sister ship the previous year.

The Challenge

We were asked to carry out essential maintenance requirements on the vessel, specifically focusing on the ship’s main engine combustion fans, supply fans, and exhaust fans.

The scope of work was comprehensive, requiring skilled engineering capabilities. Key objectives included:

  • On-site bearing replacement where feasible.

  • Thorough inspection and pre-recording of electrical readings before disconnection.

  • Safe electrical and mechanical disconnection of units.

  • Post-disconnection inspection and recording of insulation values.

  • Reporting any abnormal findings to the ship’s staff.

  • Cleaning of all necessary areas.

  • Extraction of old bearings and fitting of new, Rotec-supplied bearings.

  • Reinstatement and electrical/mechanical reconnection, including insulation tests.

  • Optional services like dynamic balancing and laser alignment were available.

The Solution

Rotec deployed a team of highly skilled engineers to the dock, who quickly commenced work on the specified fan units. Their methodical approach ensured every step was executed with precision and adherence to safety protocols.

During the process, the team identified several critical issues that required immediate attention:

  • A supply fan, upon removal from its trunking, revealed cracks in its mounting bracket, which were promptly welded for repair.

  • A significant crack was discovered on the lug of the Non-Destructive Examination (N.D.E) endshield. Rotec swiftly sourced and fitted a replacement endshield, adapting it for the absence of a vibration sensor aperture.

  • Both vibration sensors for the bearings were found to be damaged beyond repair, necessitating the sourcing of new replacements.

  • The fan cowl also showed evidence of a previous crack and weld repair.

 Despite these unforeseen challenges, Rotec’s engineers demonstrated exceptional problem-solving skills and adaptability. The fan unit was meticulously reassembled with new, high-quality bearings supplied by Rotec. A rigorous insulation test was performed, yielding a reading greater than 2Ω, confirming the unit’s electrical integrity. Following reassembly and testing, the unit was run to the complete satisfaction of the ship’s staff.

 The Feedback

The client’s Assistant Electrical Manager commented,

“I’d like to personally thank your engineers for their excellent work. As always, they have been a pleasure to work with, delivering the job on time and to a high standard. All work has now been tested and officially signed off by the ship.”

Conclusion

By proactively identifying and resolving complex issues, Rotec ensures that critical marine equipment functions optimally, contributing to the safety and efficiency of global maritime operations. Our engineers carried out the job within the timeframe required – something that is critical to the Marine industry. Rotec looks forward to continuing its partnerships, and further supporting the marine industry within Cornwall, the South West and beyond.

As a certified Parker distributor, Rotec Hydraulics is at the forefront of designing and building custom hydraulic systems that are not just powerful, but also smart. By integrating Parker’s IQAN electronic control system, we create solutions that enhance safety, boost efficiency, and provide unprecedented control over your equipment.

What is Parker IQAN and What are the Benefits?

Parker IQAN is a state-of-the-art electronic control system specifically designed for mobile hydraulic applications. It’s an integrated ecosystem of controllers, displays, joysticks, and sensors, all managed by a powerful and user-friendly software suite.

 The key benefit of IQAN is its ability to replace complex mechanical and electromechanical systems with a streamlined, totally electronic approach.

 Rotec has successfully designed, built, programmed and installed a variety of custom IQAN-enhanced systems. Clients have reported benefits including:

Enhanced Safety

IQAN controllers enable critical safety features like dual-channel fail-safe circuits and emergency stops which can be operated remotely. This enhances safety – keeping operators out of harm’s way, especially in hazardous environments such as quarries or construction sites.

Precision & Control

The software allows for precise, proportional control of hydraulic functions. Instead of simple on/off levers, operators can achieve infinite speed control and finely tune movements with joysticks and other input devices. This leads to more accurate and efficient operations.

Monitoring & Diagnostics

IQAN systems provide real-time monitoring and advanced diagnostics. The software logs events, and can alert operators to potential issues before they cause a breakdown. This proactive approach to maintenance dramatically reduces downtime and lowers repair costs.

Remote Accessibility

Rotec can build systems that allow for remote monitoring, diagnostics, and even software updates. This means operators can access the system’s data from a laptop or smartphone, diagnose a problem, and potentially resolve it without needing to be on-site.

l

Customisation

IQAN software is flexible and user-programmable. Rotec Hydraulics’ in-house design team can customize the system to your specific needs, building in tailored functions, adjusting parameters, and creating a user interface on the display that is intuitive for your operators.
