Lindsey Oil Refinery is one of the largest refineries in the UK, processing around 10 million tpy. In 2018 the facility celebrated its 50th year of production and has continued to look to the future. Over the last two decades the refinery has been improving its capability to produce ultra-low-sulfur fuels so that it can become a cleaner and more efficient operation.
An installation was planned as part of wider maintenance and upgrades during a plant turnaround. Such turnarounds require large investment and are planned in detail, so it was vital that the project was kept on track.
ALE was tasked with lifting and transporting the new sulfur storage facility, which consisted of a concrete pit, weighing 304 t, and its lid, weighing 90 t. The new pit had been cast into the ground so had to be lifted with a large degree of precision. At 17 m long and 4.1 m wide, the pit’s size would also make it challenging to transport.
To lift the sulfur pit, the company mobilised its Lift ‘N’ Lock gantry lifting system. The system’s jacking points can all operate in unison to maintain optimum control and safety.
The system was rigged with a bespoke rigging arrangement to lift the sulfur pit, then ALE manoeuvred specialist 3 file SPT axles beneath it. The pit was transported almost two miles to its final location along public and site roads.
The lifting and lowering process was then repeated for the pit’s lid. Its different dimensions meant ALE had to design a second bespoke rigging arrangement. Due to its smaller size, ALE was able to transport the lid on a much shorter and more direct route.
With the concrete sulfur pit ready for installation, the refinery’s schedule was kept on track, ensuring it could continue to supply the market throughout the turnaround. The new pit will enable Lindsey Oil Refinery to store more extracted sulfur at the refinery before it is removed to be used in a variety of industrial applications.
