Allelys wraps up transport for a UK power project

Allelys wraps up transport for a UK power project

Allelys were recently contracted to transport and install fifteen components for the Rassau project, being developed to add frequency stability to the power grid in the UK. The units made up synchronous condenser, the first to go live within the UK.

The components, with weights ranging from 7.5 tonnes to 200 tonnes, were scheduled to be installed into a generator hall in South Wales. The confined space within the hall added an extra layer of complexity to the project and required a bespoke engineering solution to be designed.

The first task was to deliver, lift and install five containers to a raised foundation. A 200-tonne mobile crane and specialist lifting tackle was used to lift each unit to its final position.

An 11.5-tonne auxiliary transformer was the second component to be received and was installed on site, again using a 200-tonne mobile crane. The third unit was a 73.5-tonne step up transformer, which Allelys received at Southampton docks onto a 6 axle MPA low loader trailer and transported to site. It was then lifted and positioned onto its foundation using a 500-tonne mobile crane.

A 450-tonne hydraulic gantry system was then mobilised on site to lift, propel and position the 9.5-tonne pony motor, utilising 2 jacks, followed by a 62.5-tonne fly wheel, utilising 4 jacks. Due to the confined space, it was then necessary to complete a partial demobilisation of the equipment by removing all of the jacks, rigging and load spreading mats, enabling a 60/80 Versa Lift to install the 7.5-tonne oil skid and 10-tonne cooler unit.

The outdoor cooler was the next to be delivered and installed. At 12 meters in length and limited lifting options, Allelys designed a bespoke lifting solution and utilised a 100-tonne mobile crane to ensure the job was completed without incident.

For the next two components, the 450-tonne hydraulic gantry system was mobilised once again.

Allelys received the 200-tonne generator at Newport, transported it to site on a 18 axle flat top trailer, where it needed to be transhipped onto SPMT due to limited space. A 100-tonne mobile crane was then used to lift the final piece, a 20-tonne cover onto the generator prior to the complete component being manoeuvred into the generator building.

The SPMT was able to transport the generator around the tight corners, negotiate a downhill section of site road and reverse inside the generator building ready to be lifted.

In addition to the transportation and installation, the Allelys team provided full engineering support and project management throughout the project.
