Permanent magnet tunnel thruster

Reliable, efficient and low through life cost

The TT-PM is engineered and built with focus on reliability and efficiency. The core mechanical technology is well proven and verified through rigorous design processes, quality control, testing and verification.

Permanent magnet tunnel thruster

The Permanent magnet tunnel thruster (TT-PM) is the latest tunnel thruster design from Rolls-Royce and has been engineered with reliability and through life costs as the focus. Using permanent magnet motor technology increases efficiency and makes the installation more compact, only the variable frequency drive unit is housed in the thruster room, freeing up space on board.

It also simplifies maintenance as the patented mount means units can be removed and replaced without drydocking. PM thrusters are currently available in two sizes with powers of 1,000 and 1,600 kW. These thrusters have been developed for the most demanding applications such as DP.

Efficient and space saving PM technology
Fast response times to full power
Rugged design with high reliability
Equal thrust in both directions
Patented resilient mounting system reduces noise and vibration, simplifies tunnel fabrication and removal/installation
Oil filled stator for superior cooling and protection
Robust centre shaft carries all propeller loads

TT-PM thrusters are resiliently mounted in the tunnel to minimise noise and vibration. Installation and removal can be carried out without drydocking the vessel.

These two pictures illustrate the significant space savings delivered by PM technology.

Due to its symmetric design the permanent magnet tunnel thruster provides increased flexibility for the ship designer to achieve a more optimal and space-saving installation.

Services & Aftermarket Support

Customer Product Training

Offering blended teaching combining e-learning, simulator training and more.

Customer Product Training

Ensuring that your crew are properly and thoroughly trained will reduce operational risk and downtime plus maximise return on asset investment.

It also enables you to meet regulatory standards, improve crew safety and retain key personnel. In our state of the art training centres qualified and experienced trainers are able to provide your crew with practical training tailored to suit your products, systems and operational requirements. Our instructors can also train your crew on-board their vessel.

From hands on experience on full sized products in our training workshops, to experiencing real life scenarios in our virtual reality simulators all of our courses are designed to focus on safe and efficient operation and maintenance of your Rolls-Royce equipment.

Regional training centres:

Ålesund, Norway
Niteroi, Brazil
Singapore

E-learning

This type of solution is ideal for course preparation, where the participant is exposed to theoretical training for fundamental basic knowledge, with e-assessments throughout the module to assist in measuring the participants understanding of the basics.

Classroom

This type of solution is ideal for theoretical training, especially for larger groups. It goes through detailed systems overview including drawings and functionality.

Workshop/technical room

This type of solution is ideal for practical training with focus on maintenance and troubleshooting on actual products. This type of training used together with classroom training can provide a holistic view of complete systems.

Simulators

This type of solution is ideal for operator training where simulations of real life scenarios occurring at sea expose crew to dangerous situations in a controlled environment. They can be configured for systems or stand-alone operations like subsea, bridge, crane or winch operations.

DP simulator

Practice manoeuvring around an oil platform in all types of sea conditions. Learn from realistic situations using operator stations arranged as on the vessel.

Winch simulator

Enhanced with a winch remote control and monitoring system, the latest winch configurations helps crew practice and learn how to handle complex winch operations.

Seismic simulator

Realistic training on deploying the streamer cable and deflector. Simulating the operator’s tasks on the back deck of a seismic vessel, using the control system together with the radio remote.

Spares

We understand the importance of having the right parts, available in the right place, at the right time.

Spares

We understand the importance of having the right parts, available in the right place, at the right time. Working in close collaboration with our customers we have now developed a Spares Transformation Programme (STP) to further improve our customer response times.

This programme will streamline our operations to reduce lead-times, increase spares availability, and allow customers to track the status of their spares delivery in real-time.

To support the programme, we have opened a dedicated Marine Parts Service Centre (MPSC) to process spares quotations and orders centrally. This is underpinned by an improved logistics and IT infrastructure, which will enable us to deliver high-quality support to our customers, wherever they are in the world.

Vessel General Permit (VGP)

Helping you to meet the new US Environmental Protection Agency regulations.

Vessel General Permit (VGP)

In March 2013, the US Environmental Protection Agency (EPA) issued a final Vessel General Permit (VGP) regulating discharge from commercial vessels in order to protect the nation’s water from ship discharges and reduce invasive species in US waters.

The new VGP will be valid from the 19th December 2013 and replaces the current VGP (2008 VGP). Under the new VGP a range of equipment is affected by discharges from oil-to-sea interfaces as well as cathodic protection.

Contacts and support

If you are interested in learning more about the VGP, or if you would like to discuss your requirements in more detail please contact your local 24/7 Technical support team:

Europe, Middle East and Africa:	+ 31 20 700 6474
