Vibration & Pulsation Analysis

Vibration Analysis

Among Brighton’s many plant services, is the expertise to solve facility piping and equipment-related vibration issues. Our flexibility enables us to be on-site quickly to witness and assess vibration issues, and perform real-time vibration measurements using our portable vibration analyzers.

Vibration Analysis

We use industry-recognized software, as well as our own in-house calculators to assess piping systems’ natural frequencies and to determine fluidic and mechanical excitation sources. This information allows us to provide efficient and cost-effective solutions for controlling detrimental vibration. Safety assessments are conducted to industry-accepted criteria developed by leading vibration specialists.

Low Temperature Brittle Fracture Prevention

Brittle Fracture

Carbon steel  toughness and ductility degrades with decreases in temperature, so designing equipment and selecting materials properly in the design stage, can prevent severe safety and equipment failure leading to injury or loss of life, loss of product and production, and all the costly consequences.

Low Temperature Pipe Analysis

Existing brownfield facilities can be analyzed by Brighton for Brittle Fracture potential under severe conditions, such as a blowdown event. Brighton can work with your engineers to help develop low temperature mitigation procedures, recommend mechanical stress-reduction installations, re-rate equipment to operate under more severe conditions utilizing Fitness for Service methodology, and in the worse-case provide material replacement recommendations in critical locations.

Water / Steam Hammer & Surge Analysis

Water Hammer

Water hammer occurs when there is a pressure wave generated from a fluid that is forced to stop, start, or change direction suddenly. In the case of steam hammer, there is a mixture of steam and condensate instead of fluid. These situations are common when a valve within a piping system is shut-off or turned-on. The pressure wave induces vibration and reactionary forces on the pipe that can compromise safety potentially causing injury to nearby personnel and severely damaging the piping and equipment, which can otherwise cause preventable downtime.

Surge Analysis

Brighton’s engineers are able to investigate the mechanisms behind water hammer sources and piping failures in both liquid-filled and two-phase steam-condensate systems. We can analyze the fluid flow at all stages of operation, simulating the increased pressures, vibration, and forces during the event and the mechanical response due to the increased loads on the piping systems.

Expansion, Swivel & Clamp Joints

From application to elimination, Brighton has the expertise to design and modify a piping system to work with or without specialized piping joints. Expansion joints are widely used when a ‘tight’ piping system does not permit the flexibility necessary to absorb axial and lateral movement, generally at the expense of robustness and longevity when compared to hard pipe. Brighton has a long history of providing sound alternatives to replace ineffective or leaking expansion joints.

Swivel joints are often used in two or three ‘knuckle’ combinations to absorb large differential movement. Incorrect design often leads to ineffective movement of the knuckle arrangement leading to possible damage or leaks.

Brighton has performed evaluations on hundreds of knuckle combinations and can provide the most effective design for any scenario.

Clamp Joints are often used in severe operating conditions where spool removal is necessary, however they can be susceptible to leakage if put under incorrect bending loads. Brighton can assess existing clamp joints for root cause failure, and modify piping to alleviate unnecessary loading to keep the joints fit and in service.

Inspection & Measurement

Brighton’s engineers are experienced in field and shop inspections, with a focus on piping systems, pipelines and structural steel. Our engineers are readily available, and can be mobilized quickly to be on site to assess operational issues.  Our inspection team have visited locations all over the world to solve issues in a wide variety of facilities
Along with vibration measurements, we can conduct temperature, sound and flow measurements on site using industry-leading equipment.  On-site dimensioning (as-builts) and photographic documentation are standard practice.

Field Procedures

Brighton’s expertise goes well into field, as we often oversee the installation of the designs we engineer. Brighton has authored many procedures to safely and correctly install, replace or modify our designs including structural steel installations, storage tank erection, and piping support modifications and installations. We work closely with foremen, millwrights and welders to understand their challenges, all with safety as the primary objective.

Process Engineering

P&ID Piping and Instrumentation Diagram

At Brighton, our process engineers focus on designing optimized systems through computer-based methods. We generally optimize chemical systems for SAGD plants, and generate the initial Block Flow Diagrams (BFDs). After the processes are refined, our Process Designers are able to detail the process and create Process and Instrumentation Diagrams (P&IDs). These drawings will then be issued and approved under the designing engineer.

Oil Sands Wear Technology Solutions

Banner - oil sands wear technology

Billions of dollars are spent annually by oil sands surface mining facilities on maintenance, replacement and repair of equipment and piping due to excessive wear and corrosion, in addition to the consequential production losses from premature failures. Oil sand is mainly composed of hard quartz, sand, silt, clay, water and bitumen. The presence of quartz and other hard solids in the oil sands has posed unique material challenges for oil sands operators.


Brighton engineers have assisted oil sand surface mining operations with developing and implementing material technology solutions to reduce the reliability impact caused by wear, erosion, and erosion-corrosion. Since 2014, Brighton has contributed an estimated operating (OPEX) cost savings of more than $13 million dollars to oil sand facilities.

Safety is more than statistics, it is a mindset that must be adopted from the start of any project, big or small. Safety is a big part of Brighton’s culture and all of our engineers and technologists receive the latest safety training including H2S Alive, WHIMIS, CSTS, and OSSA. We are equipped with all of the necessary safety gear required to visit most industrial facilities to perform our on-site services.
