Engineering problems in industrial settings don’t arrive in neat categories. A bulk material handling system has structural implications. A pressure vessel connected to a process line raises piping stress questions. A storage tank near an active fault zone needs seismic analysis before anyone can sign off on it. The disciplines that get separated into different service lines in a large firm’s org chart tend to collide in the field, and the projects that go smoothly are usually the ones managed by engineers who understand those collisions rather than ones who work only inside their own lane.
Little P.Eng. Engineering was built around this reality. Operating across Canada and the United States, the firm delivers a technically integrated suite of services covering structural, mechanical, and process engineering disciplines, with the specific depth in each to handle the work that genuinely matters to industrial, energy, and infrastructure clients.
Bulk Material Handling Engineering
Bulk material handling is one of those disciplines that looks straightforward until the material stops moving the way it’s supposed to. Flow characteristics of granular solids are notoriously difficult to predict from first principles, and the gap between what a theoretical design suggests and what the actual material does in a real hopper, chute, or conveyor system can be substantial.
Little P.Eng.’s bulk material handling engineering services are supported by discrete element modeling, which is worth covering separately below, but the engineering approach extends beyond simulation. Structural support design for conveyors and transfer points, load analysis for storage silos, and the integration of handling systems with broader plant layouts are all part of what the firm delivers. Getting the material flow right is one thing. Making sure the structure around it is designed for the actual dynamic loads the system generates is another, and both need the same level of attention.
Seismic Design and Structural Engineering Services
Seismic design in Canada and the United States is governed by code requirements that have become more demanding in successive editions of the National Building Code and ASCE 7, and meeting those requirements for industrial structures, storage tanks, pressure vessels, and process equipment requires more than applying a static force multiplier. Equipment attached to structures, non-structural components with significant mass, and irregular geometries all introduce complexities that require proper dynamic analysis rather than simplified methods.
The firm’s structural engineering services cover steel and concrete systems across the project lifecycle, from concept through detailed design and into documentation for construction. For clients in seismically active zones, this means seismic design is integrated into the structural work from the outset rather than being retrofitted as a check at the end of the design phase. That integration matters because the most efficient seismic designs are ones where the load path is considered from the beginning, not ones where a completed structural design is subsequently assessed for seismic adequacy.
Piping Stress Analysis Services
Piping systems in process plants and industrial facilities experience thermal expansion, pressure transients, vibration, and imposed loads from connected equipment. A piping system that isn’t designed with these loads properly accounted for develops problems that range from nuisance to catastrophic, and the failure modes are often not immediately obvious from visual inspection.
Little P.Eng.’s piping stress analysis services use established analysis software to model thermal and mechanical loads, assess stress against code allowables under ASME B31.1, B31.3, and B31.4 as applicable, and design support arrangements that allow the system to move without overstressing pipe, fittings, or connected nozzles. The support design is as important as the analysis. A stress analysis that identifies a problem at a nozzle connection and then specifies an appropriate restraint scheme is delivering value. One that identifies the problem and leaves the support engineering as someone else’s problem is only half done.
Plant 3D Modeling, Piping Design, Isometrics and Spool Generation
Modern plant design is increasingly done in 3D environments, and for good reason. The clash detection, spatial coordination, and constructability verification that 3D modeling enables are genuinely valuable on complex projects where multiple disciplines are working in the same physical space.
The firm delivers full plant 3D modeling services including detailed piping layouts, and from those models produces the isometric drawings and spool drawings that fabricators and field crews need to actually build the system. The connection between the 3D model and the fabrication deliverables is where errors get introduced when the handoff isn’t managed carefully, and keeping that process in a single workflow reduces both errors and the coordination overhead that comes from managing it across separate groups.
Above-Ground Storage Tank Design
Above-ground storage tanks are designed under API 650 for welded storage tanks, API 653 for tank inspection and repair, and API 620 for lower-pressure tanks, among other applicable standards. The design work involves shell thickness calculations, annular plate design, wind and seismic loading, and foundation interaction, and for tanks in seismic zones the requirements are more involved than many clients anticipate going in.
Little P.Eng. provides above-ground storage tank design across the range of sizes and service conditions that industrial clients encounter, with the seismic design capability to handle projects in zones where simplified approaches are insufficient. The CRN registration process for tanks used as pressure vessels in Canadian jurisdictions is also part of the firm’s service offering, which means clients aren’t managing two separate relationships for the design and registration components of the same piece of equipment.
Pressure Vessel Design and CRN Registration
Pressure vessels in Canada require registration with the provincial regulator before they can be placed in service, and the registration process involves demonstrating that the vessel has been designed to the applicable edition of the ASME Boiler and Pressure Vessel Code and that the design has been reviewed by a registered professional engineer in the province of use.
The firm handles both the pressure vessel design under ASME Section VIII Division 1 and the CRN registration process, including preparation of the design documentation required by the provincial registration bodies. CRN registration can be a process that takes longer than clients expect if the documentation isn’t prepared to the standard the registration bodies require, and having the design and registration work managed by the same team reduces the back-and-forth that extends timelines.
Discrete Element Modeling
Discrete element modeling is a simulation approach that tracks individual particles rather than treating bulk material as a continuum. For problems involving granular flow, segregation, chute design, and equipment wear, DEM produces insights that continuum methods can’t, because the behaviour of granular solids at the particle scale is fundamentally what determines the system-level behaviour.
Little P.Eng. uses DEM analysis to validate and optimize bulk material handling designs before they’re built, identify segregation problems in storage and transfer systems, and assess wear patterns in chutes and transfer points. The analysis is particularly valuable for new equipment designs where physical testing isn’t practical, and for troubleshooting existing systems where the problem is understood qualitatively but not quantitatively.
Pipeline Rehabilitation Using CIPP Liner
Cured-in-place pipe lining is one of the more cost-effective methods for rehabilitating deteriorated pipelines without excavation. The structural design of CIPP liners requires analysis of the host pipe condition, the loading case for which the liner needs to provide structural capacity, and the liner thickness and material properties needed to meet that capacity under applicable design standards.
The firm provides engineering for pipeline rehabilitation using CIPP liners, including the structural calculations that support the liner specification and the documentation required for regulatory submissions. For municipal and industrial clients facing aging pipeline infrastructure, CIPP represents a way to extend service life significantly at a fraction of replacement cost, and the engineering needs to be done properly to ensure the liner design matches the actual rehabilitation objective.
FEA Nozzle Analysis Services
Nozzle connections on pressure vessels and storage tanks are stress concentration points, and when the loads imposed by connected piping are significant, demonstrating that the nozzle connection is adequate requires more than the standard area replacement approach in the ASME code. Finite element analysis of nozzle connections under combined pressure, thermal, and piping loads provides a direct assessment of stress at the connection that the simplified code methods don’t capture.
Little P.Eng.’s FEA nozzle analysis services are used when piping stress analysis identifies nozzle loads that exceed the allowable loads for the connection, when the geometry is outside the range for which standard code methods are valid, or when a client needs to demonstrate fitness for service for an existing connection. The analysis produces stress results that can be compared against ASME Section VIII Division 2 acceptance criteria or WRC Bulletins, giving the client a documented basis for the adequacy of the connection.
A Technical Partner Across the Project Lifecycle
The breadth of Little P.Eng.’s service offering reflects the reality of how engineering problems present themselves in practice. A storage tank project might need structural design, seismic analysis, pressure vessel engineering, CRN registration, piping stress analysis for the connected lines, and FEA nozzle checks at the most critical connections. Managing those services across multiple firms adds coordination overhead and creates gaps where no one is responsible for the interfaces between disciplines.
Working with a firm that covers the full range means the interfaces are managed internally, the technical assumptions are consistent across disciplines, and the client has a single point of accountability for the integrated engineering work. For industrial, energy, and infrastructure clients across Canada and the USA, that integration is often where the real value is delivered.
