FEATURE SPONSOR ONSHORE OPERATIONS & MAINTENANCE


The provision of all this data identified several requirements along the route to enable the convoy’s safe passage, this included street furniture removal, relocation of signage and lamp posts, pruning of foliage, third party land requirements and certain sections where the placing of track way would be necessary.


The tower sections would move freely along the route but these special measures were essential for safe delivery of the blades. After liaising with several authorities, highways departments and constabularies the route was agreed and adapted to accommodate the convoy, now all that was needed were the turbines themselves.


SHIPPING


Cue the arrival of the ships. Handled by Collett’s Marine Division, two vessels were expected at the Port of Grangemouth, the first arriving from Poland carrying the nine turbine blades, the second from Turkey carrying the nine tower sections.


As the vessels arrived the company was on hand portside ready to begin the discharging of the ships. One by one each of the components were safely lifted from the vessel to an agreed laydown plan portside at their Grangemouth Heavy Lift Storage Facility. Utilising the company’s 110Te straddle carrier and various craneage equipment, each component was strategically positioned to allow for ease of loading in line with the delivery schedule. Here the loads would remain until the stage of construction at Muirhall could facilitate delivery allowing Collett to provide a 'Just in Time' service.


HUBS AND NACELLES – ANOTHER CONSIDERABLE CHALLENGE


The hubs and nacelles for each turbine were located in Germany. This provided yet another logistical challenge requiring expert co-ordination from Collett to ensure an orchestrated arrival of the components necessary for each complete turbine. The company once again rose to the challenge, with expert logistical planning and execution they ensured that deliveries of these integral components fell in line with the agreed schedule.


DELIVERY DETAIL


As the end of November approached the first delivery to site set off. In order to minimise disruption, and due to the size of the cargoes and the route they would be travelling, each convoy consisted of one tower section and one turbine blade.

Accompanied by Collett’s pilot vehicles and under police escort the convoy made its way along the route, manoeuvring the components through the villages of South Lanarkshire with their expert drivers effortlessly taking the challenging route in their stride.


After crossing splitter islands, employing contraflow manoeuvres and utilising manual steering at key points throughout the route all components arrived safely on site ready for construction.


DELIVERY SCHEDULE


Working on a 6 day a week delivery schedule, and adopting the blade and tower delivery combination, each component safely made the journey from Grangemouth to site, arriving in synchronisation with the construction schedule.


Working closely with the experienced Muirhall wind energy team on both this and the previous phase two extension allowed the company to provide expert logistics throughout.


RISING TO THE CHALLENGE


From coordinating the arrival of components from three separate locations across Europe to the extensive planning and execution of manoeuvring a 63.35m loaded combination, Collett rose to the challenge and are proud to say that they’ve delivered the largest onshore turbine blade in the UK.


Muirhall Windfarm phase 3 extension, also known as Muirhall South is expected to be operational in early 2016 and will offset circa 10,848 tonnes of CO2 per annum whilst supplying up to 5,773 homes with electricity over the 25 year lifetime.
