Sarens recently completed two major projects in Scotland. At Glasgow’s George V Dock, Sarens was contracted to offload a 142-tonne vapour recovery unit (VRU). Sarens also managed the transportation and installation of two 1,600-tonne swing bridge sections destined for Renfrew.
deugro contracted Sarens to offload a 142-tonne vapour recovery unit (VRU) from a flatbed trailer at the George V Dock in Glasgow. Responsible for planning the lift, selecting a suitable crane, organising the slinging and signalling arrangements, and supervising the operation, Sarens used an LTM 1450 with a main boom of 134 tonnes counterweight.
The LTM 1450’s versatility, with its various based outriggers, was crucial to the project. It is equipped with a Vario base which allows the outrigger to be set at different distances, so the crane could be as close as possible to the VRU.
The dock handles biomass, bulk dry and agricultural products (such as animal feeds, aggregates and grain), wood and forest products, metals, chemicals, industrial equipment and wind turbine components among others. The dock’s VRU is the system that recovers all fugitive emissions at the loading terminal and the storage tank facility, with these emissions occurring when storage tanks need to relieve pressure. Prior to the introduction of VRUs, these emissions were either vented to the atmosphere, flared, or sent to a vapour combustor.
Sarens has also been working on another project in Scotland, the company having transported two 1,600-tonne swing bridge sections to Renfrew.
Measuring 92 m long x 18 m wide x 38 m high, the bridge sections were both constructed in the Netherlands – with the south bridge constructed by Hollandia Infra in Rotterdam, and the north bridge by Smulders in Flushing.
After examining the site conditions in Rotterdam, Flushing, and Glasgow, Sarens deployed its Caroline barge, 26 ballast pumps, and six hydraulic winches. SPMTs in various configurations (six 10 axle-lines, two 16 axle-lines, and two 12 axle-lines) and ro-ro ramps of 2.8 m, 5.8 m, and 9 m. Some equipped was shipped on the barge, with the rest transported by road.
The south bridge, built in Rotterdam, was transported to the quayside using six 10-axle line SPMTs, lifted by three sheerlegs, and loaded onto Sarens’ barge, Caroline. Once secured, the barge was towed to Glasgow, with pre-assembled SPMTs moving the bridge to its final position on temporary jacks.
The north bridge, built in Flushing, was transported to the quayside using 32-axle lines of SPMT, before being driven onto the barge during a load-out operation and transported to Glasgow, with the same installation order as the south bridge.
The two-lane road bridge across the River Clyde spans 184 m from Renfrew to the boundary between Glasgow and West Dunbartonshire, with the new routes envisioned to reduce congestion and shorten journey times, improving public transport reliability. The project is jointly funded by the UK and Scottish governments via the GBP1.1 billion (USD1.4 billion) Glasgow City Region City Deal.
The two-lane road bridge across the River Clyde spans 184-m from Renfrew to the boundary between Glasgow and West Dunbartonshire. The bridge is due to be completed ahead of schedule and be fully operational for pedestrians, cyclists and motorists in this autumn.
