Rotec completes innovative remote monitoring system onboard a vessel

As equipment increases in complexity, there is a growing need and advantage to being able to monitor parts of, or a complete system remotely.

With a long held commitment to innovation, Rotec Hydraulics are the first known company in the UK to have designed, installed and commissioned Parker IoT software that remotely monitors a hydraulic system.

With the ability to be installed and remotely monitor any hydraulic system, Parker Internet of Things (IoT) technology allows a user to ensure their assets are working at full functionality by monitoring key performance indicators, such as temperature, pressure and flow.

The remote monitoring technology further benefits the user by providing vital performance feedback for preventative maintenance planning, and can monitor real time and historical data all within a simple web-based interface.

This web-based portal can be accessed worldwide and gives a further benefit of GPS asset tracking and visibility – thus aiding both security of equipment and logistical transport efficiency which in turn, can reduce fuel costs.

The innovative IoT project came to fruition following Rotec being asked by a boat manufacturer to gather information about the performance of the hydraulic system they were fitting to a new fleet of vessels. 

Because of the harsh marine environment, robust equipment was selected that meets high ingress protection. IoT modems are compact and have built in aerials allowing for a sealed solution, meeting strict IP67 ingress protection and wide temperature ranges of -30 to +75 degrees.

Multiple sensors were fitted by Rotec’s engineers to provide feedback of tank levels, oil temperatures, flows and pressures in various parts of the system.

A further enhancement was provided by adding a particle contamination device which monitors and uploads the vessel’s oil cleanliness data to the cloud. Previously hydraulic oil changes were performed on a time expiry basis, whereas adding sophistication of a real time oil contamination device now tells the customer when the oil needs to be changed rather than changing at estimated time intervals. This reduces both the cost for the customer and decreases the impact on the environment because they are now performed only when required.

The customer was particularly impressed as Rotec Hydraulics were able to code unique software and download this remotely to assist with additional logging during sea trials of the vessel before delivery for normal operations at sea. This provided additional information that has not previously been visible due to the nature of the testing preventing personnel being on board monitoring the systems from the bridge. 

The IoT can be connected to an engine ECU using standard j1939 CAN protocol to give live engine data to be able to monitor remotely. This can provide data feedback from various sensors to ensure optimal engine performance and critically, no abuse of the equipment when being used in the field.

Alerts can be set and configured to automatically send emails once thresholds are exceeded, enhancing the effectiveness of automated data upload. 

Built in Bluetooth and WiFi also allows the user to access the password protected modem locally to download logs and further enhance the remote experience. Software updates can be performed remotely over the web or by Bluetooth/WiFi to increase the functionality of the sampling controller or change data collection and upload frequency, allowing for maximum end user flexibility for the customer.

Hydraulic fuel system with integrated pipework solutions carried out by Rotec

Rotec engineers have carried out integration and commissioning of a hydraulic fuel system with pipework solutions on a brand new vessel for a prestigious boatbuilder.

After being let down by another supplier, the client requested Rotec to carry out the works following referrals made by others within the Marine industry who had given Rotec glowing reviews.

A reliable and efficient hydraulic fuel system, built with quality components, aids any vessel engine to run smoothly, avoid unexpected engine failures and ensure passenger safety. Additionally, built and maintained to a high standard, a hydraulic fuel system will be compliant with good practice and environmental regulations.

Rotec’s engineers, whose skills and experience span across multiple engineering disciplines – from hydraulics to electrical – installed and commissioned the hydraulic fuel system in line with the boatbuilder’s schedule of works.

The hydraulic tank design supports 2 hydraulic pumps, driven by 2 engines. The flow rate from each pump (45cc per rev) is estimated at a max 70LPM. The system also supports 2 thrusters, coolers and LS lines.

All pipework solutions used 50mm and 25mm stainless tube with 1.5mm wall thickness. This reduced the number of joints, whilst providing good circulation. Pipework materials centring on the use of rigid tube within the engine machinery space and completion of service points with flexible were employed where required. Finally, pipework was cleaned utilising the pelleting system and flushed.

All hoses were supplied by Rotec and supported by the Parker Tracking System (PTS). This labelling scheme enables a user to quickly scan any asset using a non-subscription, free mobile app. The asset’s technical specifications, including part number are then displayed, enabling efficient and accurate re-ordering of parts when required. App users can also set up service alerts to notify them of when a part’s lifespan is coming to an end.

Multi-million pound refurbishment of MS Bolette unveiled

Supported by Rotec’s electrical mechanical services team, a multi-million pound refurbishment of MS Bolette has been unveiled to CLIA and Government officials.

The Bolette entered dry dock for a 13-day refurbishment, including maintenance to the ship’s Azipods and bow thrusters as well a new application of anti-fouling paint. Rotec Hydraulics Ltd, based across the South West of the UK, were responsible for the overhaul of Bolette’s eight thruster fans.

After the fans were electronically and mechanically disconnected, the vessel’s thruster fans were transported by Rotec for a full inspection. Following the inspection of all plate detail and insulation valves, the fans underwent dynamic balancing. The units were then transported back to the shipyard and reconnected, with a full works report supplied to the client.

The turnaround for the project was a mere 8 days from the ship arriving in the UK shipyard to Bolette setting sail again on 7th March. To ensure the tight deadline was met, Rotec engineers went above and beyond, working a 24/7 split shift pattern. Unplanned and additional emergent works which occurred, were quickly responded to by the Rotec team. Following the works, Mark Terrell, Electrical & Maintenance Manager at A&P Falmouth commented on Rotec’s service delivery:

“I would like to take the opportunity to thank you for the support. The Rotec response was great and by Monday 16:00 (less than 24 hours later) the ship had passed off all 8 fans as complete and ready to return to service. Special mention must go to [your engineers] for sticking with the job through Sunday night and well into Monday!”

MS Bolette has now sailed to Newcastle to complete its spring/summer season operating in Europe. Owned and operated by Fred. Olsen Cruise Lines, Bolette was formerly named Amsterdam and was the last ship of the four Rotterdam class (R class) cruise vessels.

Rotec supports new immersive visitor experience at the Fleet Air Arm Museum

The Fleet Air Arm Museum will be wowing visitors with their new state-of-the-art, immersive Carrier Experience after a £1million refurbishment.

Rotec Hydraulics Ltd were pleased to carry out works on the hydraulic and electrical systems that are integral to the simulator experience at the museum, which houses aircraft and artefacts from the flying arm of the Royal Navy.

In addition to replacing over 50m of hydraulic hose, all hoses were uniquely identified using the Parker Hannifin PTS bar-code labelling system to ease traceability and future renewal. Rotec engineers also refurbished all hydraulic cylinders and repaired the two hydraulic pump units to ensure pressure and flow performance are maximised. Other works included replacement seals, filters and directional valves, strip and clean manifold assemblies and reservoir cleans.

Adjacent to the hydraulic works, Rotec carried out electrical works on the customer experience feature at the museum in the main pump room, remote control room and on the scissor lift which raises and lowers visitors during the simulation.

In the main pump room located control panel, Rotec removed existing obsolete Toshiba PLC unit hardware, and installed a newly supplied 24VDC 10A switch mode power supply module plus protective devices. A rewire the existing safety monitoring control relay and circuit was required to provide a dual channel redundant protective emergency stop circuit.

Rotec designed, supplied and installed replacement PLC hardware to replace the Toshiba module, which was then fully programmed with the required application specific logic code to ensure the scissor lift would rise and lower in time with the attraction’s audio-visual experience.

In the remote control room, Rotec supplied and installed an operator’s control station and local 24VDC power supply. The control station included a nominal 8” full colour touchscreen HMI device fully programmed with all existing and planned operator controls, indicators and alarms.

The works Rotec has completed in part of an overarching Carrier Experience. The new experience, which is dedicated to the memory of generous benefactor Vice Admiral Sir Donald Gosling KCVO, Vice Admiral of The United Kingdom, combines digital technology with the scale of a carrier flight deck to transport visitors from the pioneer years of the First World War, all the way to the modern HMS Queen Elizabeth class carriers of today.

Adam Gosling, of the Gosling Foundation comments,

“Vice Admiral Sir Donald Gosling KCVO, Vice Admiral of The United Kingdom founded the original Carrier Experience that opened in 1994 and has welcomed over four million visitors.

 

“To see the Experience reinvigorated and made meaningful and relevant for today’s audience is the perfect way to celebrate my late father’s enduring support of the Fleet Air Arm Museum. It reflects a mutual vision to preserve and showcase the proud history of British naval aviation. His generous legacy gift has enabled, once again, the illustrious tale of Britain’s aircraft carriers to be told, and enjoyed, for many more generations to come.”

Professor Dominic Tweddle, Director General of The National Museum of the Royal Navy says,

“The re-imagining of the Carrier Experience to include the Queen Elizabeth Class, the pride of the British fleet, demonstrates our ongoing commitment to the history of naval aviation and telling the story of the contemporary navy. This mix of heritage and modernity mirrors the projects that Vice Admiral Sir Donald Gosling KCVO, Vice Admiral of the United Kingdom so generously supported over the years.

 

“I am certain that the work of the staff team, contractors and corporate partner Lockheed Martin has brought to life the Carrier story in the way that Sir Donald had in mind when he made his legacy gift.  It is both an honour and a pleasure to recognise his lifelong support with this exhibition, which is housed in The Gosling Hall.”

Rotec were chosen to complete the works due to their impressive ability to combine hydraulics with complex electronic control systems. The works were completed in a matter of weeks, on schedule and to a high standard.

Ground-breaking Project successfully crosses the Atlantic Ocean

A pioneering project, supported by Rotec Hydraulics Ltd, has achieved a fully autonomous ship sail across the Atlantic Ocean.

Solo and unaided, the Mayflower Autonomous Research Ship (MAS) set sail from Plymouth harbour in the UK and reached its end destination of Plymouth USA on 30th June 2022 after 36 days at sea and 3,900 miles, having made two stops in Horta (Azores) and Halifax (Canada).

The futuristic vessel was powered by AI and powered using renewable solar energy technology, and a backup diesel generator for night sailing. Throughout the journey, the vessel collected data that researchers hope will provide critical information in the battle to safeguard the future of our oceans. A challenging project relied on a diverse team that spanned 10 countries and 3 continents, including Rotec Hydraulics Ltd.

ProMare, a US based non-profit organisation with a branch in Plymouth UK, teamed up with IBM to build the third Mayflower and asked Rotec to supply a range of hoses and hose assemblies to support the project. Rotec was also pleased to be able to help spread the word of crowdfunding efforts at the start of the project.

Brett Phaneuf, Managing Director of the MAS Project, commented:

 “[The Mayflower Project is] ushering us into a new phase of oceanographic and climatological research with state-of-the-art technology.”

Paddy Dowsett – Project Manager, MSubs says:

“This project brings a number of new  technologies together in a way that hasn’t been done before. There are some smaller autonomous crafts in existence, however nothing anywhere near this scale in terms of size and technicality.”
