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.”

Rotec deliver custom upgrade and HPU builds for leading manufacturer

Recently designed and manufactured, engineers at Rotec Hydraulics Ltd have completed a bespoke project for a market-leading manufacturer.

The British-based company specialise in the manufacture of electronic valve actuators for large fluid flow applications, for example within the oil and gas, water and power industries. The actuators produced are a considerable size and as such, part of the development process includes dynamic load testing. The actuators connect to a test cylinder via a screw thread; as the actuators move the screw thread up and down, this in turn pushes and pulls a hydraulic cylinder.

 Full of hydraulic fluid, the operators were manually operating needle valves to restrict the flow of the hydraulic fluid within the cylinders in order to vary the amount of load on the actuator. Thus, Rotec design engineers developed two key upgrades to this current setup which were:

  • Electrify the load control valves so they can be operated by a computer.
  • Create a power pack which can induce a given pressure inside the test cylinder bores.

 The newly custom-designed system reuses the current cylinders that vary in size from 63mm in diameter to 203mm. To accommodate for this, different sized stands with varying tank sizes have been manufactured to accommodate the extra capacity whilst the control components remain the same. The stands consist of:

  • A custom powder coated steel frame.
  • An aluminium reservoir.
  • Dual electronic proportional pressure relief valves.
  • Dual manual needle valves.
  • Dual ball valves.
  • Quick connect ports for the power pack to connect to.
  • Output ports which connect to the test cylinder.

In addition to this, Rotec developed and built three identical standalone hydraulic power unit (HPU) systems which can create steady state pressures inside the test cylinders bores to eradicate erroneous pressure lag errors. Features include:

  • Powder coated mild steel tank construction.
  • 3 phase motor coupled to a gear pump.
  • Air blast oil cooler.
  • Direction control valve.
  • Dual proportional relief valve.
  • Electronic control box.
  • Stainless steel tool tray.
  • Whole unit is mounted on castors for easy manoeuvrability.

Stroud Engineers Deliver Major Refurbishment Projects at BMW

Rotec engineers carried out a major refurbishment of the Feed Line and Press at a BMW plant in Gloucestershire.

Over 160 hydraulic hoses on the Feed Line, and 66 hoses on the Major Press were removed and new hoses made and fitted.

This was a challenging job due to the complexity of the machinery and included hoses on the Feed Line HPU (hydraulic power unit), Press and Overload/Protection/Lubrication HPUs. Feed Line Pneumatic cylinders, valves and tubings were also supplied and fitted, in addtion to a total of 48 existing hydraulic cylinders on the Feed Line removed and new cylinders fitted.

Further work taken on the Feed Line, Press and Overload/Protection/Lubrication HPUs included:

  • Draining of the working fluid and cleaning of the reservoir.
  • Replacement of pressure and return hydraulic filters, pressure and return.
  • Replacement of pressure and return hydraulic filters, pressure and return.
  • Resealing of duplex filter block.
  • Removal of existing and refitting of new motor pump sets.
  • Thorough cleaning and inspection.
  • Removal of existing and refitting of new air blast coolers.

All refurbishment works were carried out on time, in budget and to the client’s expectations and standards.
