Corinth Pipeworks secures landmark offshore contracts in the North Sea

Corinth Pipeworks, a global supplier of steel pipes and solutions for the energy and construction sectors, has been awarded two offshore contracts in the North Sea from Subsea7. The projects, Bestla in Norway and Bittern in the UK, further establish Corinth Pipeworks’ strong geographical presence in the region and underscore its long-term relationships with key customers. The Bestla project is operated by OKEA is located in the Norwegian Continental Shelf, approximately 13km south of the Brage Field. The scope of the contract includes the supply of 12.5km of 14" high frequency welded (HFW) steel pipes. The development plan for Bestla involves a two-well subsea tie back to the Brage platform, which will serve as the host facility for production, processing and export of gas and liquid fuels from the Upper Jurassic Sognefjord Formation. The Bestla project aims to create additional value through cost An important details of Corinth Pipeworks’ approach to these projects is the inclusion of external coating applications, which will be performed at the same location as the pipe manufacturing. Corinth Pipeworks is uniquely equipped to apply external coating to 22.9m steel pipes within its own facility. It is a leading steel pipe manufacturer for the global energy and construction sector with projects executed in more than 55 countries worldwide.

Corinth Pipeworks’ involvement in this project illustrates its ability to support innovative approaches to maximise resource extraction while minimising costs. In the UK Central North Sea, the Bittern project entails the manufacture and supply of approximately 22km of HFW steel pipes for a 12" water injection pipeline, scheduled for installation in 2025. Located approximately 190km east of Aberdeen, this pipeline will replace the existing line to maintain reservoir pressure support for the life of the Bittern field. Subsea7, the main contractor, will manage the installation of the lined pipeline, subsea structures and tie-ins at the Triton Floating Production Storage & Offloading vessel and the Bittern field.

The processes in refineries often place high demands on the materials used and renewable fuels are particularly challenging. The raw materials used usually contain chlorides, which can cause corrosion. Therefore, special materials are required that can withstand high temperatures and aggressive chemical environments without corroding. Group Coek a heat exchanger manufacturer and one of Alleima’s long standing customers, booked the order with Preem. “Before a decision could be made, we conducted extensive lab tests together with Preem, which showed that Sanicro ® 35 can withstand the extreme conditions and process environments of the pre treatment plant. This resulted in a strong alternative to the more expensive nickel based alloys that are otherwise used,” said Barinder Ghai, director technical marketing, new business development for the tube division at Alleima.

will reduce fossil fuel production by a corresponding amount. “Reducing greenhouse gas emissions is one of the great challenges of our time. I am therefore proud that Preem is now making the biggest change in the company’s history. We are doing this by converting the diesel plant at the refinery in Lysekil. When the conversion is complete, we will be Scandinavia’s largest producer of renewable jet fuel,” said Tommy Johansson, project manager for the ICR project at Preem. The changeover means that Preem will no longer use fossil raw materials such as crude oil, but renewable raw materials instead. To make this possible, advanced technology is required, not least in the pre-treatment unit (PTU) that is to be built. The raw materials will be pre-treated and purified at high temperatures before being used in the production of renewable fuels such as hydrotreated vegetable oil, the diesel made from vegetable oils or plant products and sustainable aviation fuel.

Alleima will supply Preem with heat exchanger tubes to be used in the conversion of the Lysekil refinery from fossil to renewable fuels. The investment is an important part of Sweden’s green energy transition and will make Preem the largest producer of renewable jet fuel in northern Europe. The redevelopment of Preem’s IsoCracker plant (ICR) in Lysekil started late 2024. Once completed, it will produce 1.2 million cubic meters of renewable fuels annually and reduce fossil carbon dioxide emissions at user level by two to three million tons annually. At the same time, Preem
