Over the past 18 months LEF has been involved with a progressive overhaul of various sections of a processing plant and pipework, within SEM’s facility in Lerwick. We were asked to deploy a wide range of skills and various tradesmen to provide appropriate solutions for SEM’s engineering requirements. As such our talented people carried out all work with the high levels of professionalism we are known for. Furthermore, we always ensured our work was conducted in a safe and time effective manner.


LEF were suited to complete the dynamic work scope due to our one stop shop facility and our effective deployment of on-site tradesmen. Within the work scope LEF completed jobs ranging from fabrication and installation of carbon steel pipework, all the way to decommissioning of buildings, with working at height required. As well as key operational works, such as the modification and installation of the facilities main processing tank which stands around 9.5m tall and made from 316 stainless steel, LEF were also appropriately suited to complete the fabrication of the corral unit due to the size of our facilities. Our large weld-hall can fabricate a variety of large structures within a controlled environment, allowing us to ensure projects are completed to the highest standards with minimal risk from the effects of the weather.




A key work scope undertaken by LEF was the fabrication and installation of the facility’s corral unit. This work involved the design and construction of a steel framework with box section inlets and raised surrounding framework. The corral unit houses aqua produce in large storage containers, our bespoke design enables SEM to easily manoeuvre the storage containers as per operational requirements.

Furthermore, LEF also led the installation and modification of the main processing tank within the facility. This tank stands around 9.5m high and around 4.5m in diameter, made from 316 stainless steel. This work scope involved the fabrication and installation of the relevant connecting stainless-steel pipework and LEF’s engineers also installed actuated valves as part of the connecting pipework which runs into the further plant.

Another aspect of the work scope undertaken by LEF included the installation of 3-inch carbon steel pipework for the diesel system within the plant.

LEF also utilised our capacity for decommissioning on various work scopes. Tasks included the safe removal of an external outbuilding and its existing chimney, alongside the removal of large storage tanks. LEF provided the working at height and MEWP trained burner/gougers to carefully remove the top walkway before cutting sections away to the correct height to allow reach by heavy machinery.

In addition, LEF carried out a tank refurbishment which included the repair and upgrade of hatch covers, inlet and outlet points. This area of work also required testing on a variety of applications within the tanks including hydro and pressure testing.



At LEF our people are the key to ensuring success in everything we do. With highly skilled individuals we are able to ensure our clients receive the best possible solution for their requests. Our employees display exemplary compliance with health and safety regulations whilst on-site or on company property and as such our people proudly reflect our company values whilst undertaking any aspect of project work.

Isaac has been with LEF, since 2020. His main role with the company relates to fabrication, and welding. “I enjoy my job due to the fantastic working environment. I can only say good things about the LEF management who are always on hand to offer support. At the SEM job, I was involved directly with the fabrication and installation of the pipelines running from the main tank. I also was involved with the construction and fabrication of the corral unit which was installed in the loading bay.”
