Our Expertise
From initial design to long-term maintenance and seismic retrofitting, we provide comprehensive engineering solutions that ensure the safety, longevity, and cost-effectiveness of your pipeline systems.
Engineering Design
SEFBO Expertise in
- Aerial pipeline crossing designs with detailed shop drawings of towers, cable systems, pipeline supports, foundations, and anchors
- Our engineering department can furnish all required engineering services worldwide including seismic analysis
- Our designs are based upon many years of observing what takes place on a crossing under actual operating conditions in the field
- A design that cuts lifetime maintenance costs in half while saving on original installation costs is SEFBO's design criteria. At the same time, we impose strict safety factor considerations in every design
Inspection Services
An inspection program by experienced pipeline bridge inspectors is the prime factor in controlling maintenance costs. From a small 200 ft. creek crossing to a 3,600 ft. river crossing, every crossing is equally important to your pipeline system's integrity.
Key Benefits Include:
- Third-party verification of your crossing's condition.
- Early detection of problems when they can be resolved more economically.
- Monitoring of coating systems to schedule recoating work only when required.
Seismic Analysis & Retrofit
We recognize that many structures require earthquake design to safeguard against failures, particularly in high-risk zones. Our engineers create solutions that not only resist seismic ground motions but are also economical, meeting Uniform Building Code (UBC) requirements.
Dynamic Analysis
We create a mathematical model to represent the physical structure, showing the spatial distribution of mass and stiffness to perform adequate calculations.
Equivalent Lateral Forces
A static force procedure to engineer a structure for ground motion, considering vertical and horizontal distribution, overturning, and drift limitation.
Modal Superposition
A simplified structural model with lumped mass, suitable for smaller bridges but may not yield enough information for more complex crossings.
Design Response Spectrum Analysis
An elastic dynamic analysis using the peak response of all significant modes to determine the structural response, based on site-specific characteristics.
Time-History Analysis
An analysis of the dynamic response of a structure when its base is subjected to a specific ground motion time history record.
Non-Linear Time-History Analysis
A detailed analysis of the lateral force system when a time history is not available, modeling the capacities and characteristics of nonlinear elements.
