deugro completes multimodal transformer delivery to Scotland

deugro and transport engineering specialist dteq have completed the delivery of two power transformers from Germany to a substation expansion project in Scotland, using river transport, coastal shipping, heavy road haulage and engineered lifting arrangements.

The operation, announced on 12 October 2026, began at a German manufacturing facility and continued through the Rhine to Rotterdam before the transformers were shipped to the Port of Leith in Edinburgh. The final road journey covered 74 kilometres, using an 18-axle girder frame with an overall transport length exceeding 64 metres.

The transformers were initially collected from the factory and moved to a nearby roll-on/roll-off jetty, where they were transferred onto a barge. dteq developed the load securing design, while representatives from deugro Germany and the engineering specialist supervised the loading operation.

Before the cargo was positioned, the barge had been prepared with grillage and stool arrangements intended to support the transformers during transport. Grillage distributes loads through an engineered structure, while supporting stools provide defined bearing positions for the equipment. The design must account for the cargo’s weight distribution and the supporting structure of the carrying vessel.

Once the transformers were in position, securing equipment was installed according to dteq’s engineering plan. This stage is necessary because heavy cargo must remain stable as a vessel moves, accelerates and changes direction. The appropriate restraint arrangement depends on the characteristics of the load and the transport platform, particularly when equipment has concentrated support points or must remain within defined movement limits.

The barge completed its Rhine journey to Rotterdam in three days, allowing the transformers to travel towards the seaport without requiring a long-distance heavy road convoy for that section. Their arrival created the next handling operation, as the units had to be discharged from the barge and prepared for shipment on a different type of vessel.

For the passage to Scotland, deugro chartered a coaster, with the transformers loaded, positioned and secured under lifting and transport plans prepared by dteq. The coastal vessel completed the journey to Leith in three days, arriving on schedule. deugro’s Netherlands team and dteq supervised the loading arrangements before responsibility passed to the UK operation for discharge.

At Leith, the transformers were unloaded using tandem lifting. This involves coordinating lifting equipment to move a large load while maintaining suitable support and control of its position. The operation requires the lift to be planned around the cargo, available equipment and working area, as uneven loading or uncontrolled movement can affect the stability of the suspended unit.

deugro did not disclose the transformers’ individual weights, the lifting equipment used or the detailed load distribution arrangements. The announcement confirms the use of tandem lifting without providing the information needed to assess the lifts against specific crane capacities.

The final 74-kilometre road movement presented different constraints from the river and coastal passages. deugro UK arranged an 18-axle girder frame, producing a transport combination more than 64 metres long. The frame provided a specialist configuration for carrying the unusually heavy and sensitive equipment along the approved road route.

Multiple axle lines allow the weight of a large load to be distributed through a transport arrangement suited to the route and vehicle configuration. The considerable overall length also affects turning and manoeuvring, particularly where roads include restricted junctions, bends or changes in width.

deugro surveyed the route before transport to identify possible obstacles and bottlenecks. Road geometry, bridges, overhead clearances and access to the destination can all constrain movements of this scale, meaning that a nominally shorter route is not necessarily suitable for a heavy transport combination.

Project managers accompanied the movement, with escort vehicles and personnel positioned at the front and rear. These arrangements supported coordination along the route and through restricted sections, although the company did not publish details of the individual traffic management measures or permits used.

Once the transformers reached the Scottish construction site, they were delivered to the designated laydown area and installed using a single-direction jack-and-skid operation. Jacking equipment allows a heavy unit to be raised or supported under controlled conditions, while skidding systems provide a means of moving it horizontally into the required position.

Final positioning can involve constraints different from those encountered during transport. Access within a substation site may be restricted by prepared foundations, existing equipment and the space available to manoeuvre. The installation arrangement must therefore be suited to the receiving structure as well as to the transformer itself.

The movement involved several distinct interfaces, from factory collection to barge loading, transfer onto the coaster, discharge at Leith and the final road journey. Each stage required suitable lifting, support or securing arrangements, with the timing of one movement affecting the availability of equipment for the next.

deugro confirmed that both transformers were delivered safely and on schedule, with installation completed in accordance with the project timetable. The company has not identified the destination substation, manufacturer, transformer ratings or individual equipment weights, but the completed route provides a detailed example of the coordination required to move major electrical infrastructure through multiple transport modes.
