Controlled bolting is the technique of applying an accurate torque load to a mechanical joint in order to assure joint integrity. Because bolted joints are frequently one of the most prevalent parts in industrial components, the durability of each connection is critical. At BLJ, we have specialised methods for accurately and precisely tightening or loosening bolts in various mechanical applications within the LNG sector.

Controlled bolting is essential in industries such as the LNG industry, where secure and reliable bolted connections are crucial. Properly tightened bolts provide better load transfer and stability, enhancing the overall performance of equipment or structures, including pipelines. This can improve productivity, reduce wear and tear of pipelines, vessels and coolers, and increase equipment lifespan. By ensuring accurate and consistent bolted connections, controlled bolting helps prevent costly repairs, rework, or equipment damage caused by improper bolt tightening. It also minimises the risk of unplanned downtime, saving businesses valuable time and money.

Flange Joint Management involves the systematic approach to ensuring the integrity and reliability of flanged connections in industrial piping systems and pipelines in the LNG industry. It includes activities such as inspection, maintenance, and optimization of flange joints to prevent leaks, improve safety, and enhance operational efficiency. Flanged joints are critical components in a piping system and are subject to wear and tear over time, so regular maintenance is crucial. At BLJ, we have specialised methods for accurately and precisely maintaining flange joints to minimise downtime in the LNG industry.

Flange Joint Management offers several benefits including helping prevent leaks and associated safety hazards, reducing downtime and maintenance costs, extending the service life of flange joints, and enhancing overall system integrity. Proper management ensures compliance with industry standards and regulations, improves operational efficiency, and minimises the risk of environmental contamination.

Hot tapping is a method of making a connection to an existing pressurised system, such as a pipeline or pressure vessel, without the vessel or pipe experiencing downtime. This prevents costly and potentially dangerous hazards while allowing for the continued operation of essential pipelines and storage tanks within the LNG industry.

BLJ’s Hot Tapping services allow for the continued operation of the plant and individual systems while repairs or modifications are being made. This means shutdown time is eliminated, saving LNG pipelines time and money. Hot Tapping also serves as a safe and efficient way of making connections to pressurised systems.

Shutdown services are comprehensive maintenance and repair activities carried out on production-critical assets and infrastructure in various industries, including the LNG sector. These services involve halting all plant activities to facilitate repairs, maintenance and equipment replacements. Shutdowns are crucial for ensuring plant reliability, compliance with safety regulations, and optimising plant performance.

BLJ In-Situ Solutions personnel are able to complete servicing operations to plant equipment on-site with portable machines to increase plant up-time, safety and productivity while reducing the time, labour and transport costs of assembling and reassembling equipment.

Any issue in the plants equipment can put the project over-budget, especially if items need to be disassembled and transported to be machined offsite. Any project facing this problem needs a fast and reliable solution to get the operation back up and running as quickly as possible. Using BLJ In-Situ Solutions portable machining equipment, our technicians are able to conduct high-quality, precision machining in-situ. This allows significant savings on personnel’s time, plant servicing and traditional maintenance costs.

Our on-site machining solutions are ideal for any plant or construction project in the LNG sector that needs quick and efficient in-situ machining services. Field maintenance is the best choice for planned or emergency shut-downs to mill, bore, drill, trepan or any maintenance task where adjustments to machinery are required. 

Where traditionally, equipment would need to be disassembled and machined off-site in a workshop, our portable machining equipment allows our expert team to conduct work in-situ.

Shutdown services facilitate the onsite maintenance and repair of plant equipment. This includes:

• Flange Facing: Flange Facing is the process of machining the contact surfaces of flanges to create smooth and flat mating surfaces. It involves removing imperfections, such as corrosion, roughness, or damage, from the flange faces to ensure a proper seal when the flanges are bolted together. BLJ technicians perform field flange-facing services using specialised machines and tools.
• Hot Tapping: Hot tapping is a method of making a connection to an existing pressurised system, such as a pipeline or pressure vessel, without the tank or pipe experiencing downtime. This prevents costly and potentially dangerous hazards while allowing for continued operation.
