Upstream Oil & Gas Fabrication in the UK
High-Integrity Pressure Vessels and Heat Transfer Equipment for Offshore Duty
Upstream oil and gas projects demand equipment that performs reliably in harsh environments with limited footprint, complex integration constraints, and exposure to corrosive media. LTi Vessco supports offshore and upstream developments with high-integrity fabrication, manufacturing pressure-retaining equipment and heat transfer systems built for long-term service.
From our facility in Bridgend, South Wales, we deliver bespoke and low-volume fabrication for upstream applications where quality, traceability, and performance are critical.
Upstream equipment is engineered to withstand corrosion, pressure, temperature variation, and operational cycling - often in compact layouts where access and installation are constrained. We work closely with EPCs, contractors, and operators to manufacture equipment aligned to specification, duty requirements, and offshore standards.
Our team is experienced in delivering under tight schedules while maintaining controlled fabrication and inspection discipline throughout manufacture.
Proven Expertise in High-Grade Materials
Material selection is critical in upstream environments. LTi Vessco regularly fabricates equipment using advanced material grades commonly specified for offshore duty, including:
-
Duplex stainless steels
-
Alloy 400
-
Alloy 825
-
6Mo
-
Titanium
This capability supports corrosion resistance, mechanical performance, and reliability in demanding operational conditions.
Equipment We Manufacture for Upstream Oil & Gas
We manufacture a range of high-integrity equipment for upstream systems and supporting infrastructure, including:
-
Pressure vessels and pressure-retaining fabrications
-
Columns and vertical process equipment
-
Heat exchangers and heat transfer assemblies
-
Skid units and packaged systems designed for offshore integration
-
Associated structural and general fabrications to suit plant layout and installation requirements
Each unit is fabricated to customer specifications with controlled fit-up, coded weld execution, and staged inspection.
Trusted by UK Upstream Operators
