Past Projects
Studies, Compliance & Documentation
Zero Liquid
Discharge
Name of project: Zero Liquid Discharge
Type of Project: Capital Cost Assessment
Our Role: SDE was contracted to prepare a study and capital cost estimate for a water treatment system.
Special Info: The study and engineering included a water balance for the entire facility, process and equipment selection, specification and budgetary equipment pricing for multiple equipment skids including a new building, interconnecting piping, foundations and road access.
Reclaim Barge Conditional Assessment
Name of project: Reclaim Barge Conditional Assessment
Type of Project: Assessment of equipment functionality
Our Role: Sacre-Davey Engineering conducted NDT, visual inspections, a pump performance assessment and an investigation of the equipment historical and operational information.
Special Info: The client had concerns of two reclaim barges at their tailings pond site for both short and long term viability. The report allowed the client to make decisions with respect to Capex planning.
Design Review of Natural Gas Pipeline
Name of project: Design Review of Natural Gas Pipeline
Type of Project: Design Review
Our Role: SDE provided design review, stress analysis and design input for a 1000 PSIG, 20” diameter pipeline servicing the new gas plant in Northern BC.
Special Info: SDE’s input saved considerable cost and effort during the design phase by developing a file transfer protocol for importing client’s 3-D pipe model directly into Caesar for analysis. The timely analysis of different variation of the proposed pipe routing also saved considerable costs at road crossings and equipment tie-in locations.
Piping Integrity
Assessment
Name of project: Piping Integrity Assessment
Type of Project: Integrity Assessment
Our Role: SDE completed an integrity assessment on steam, condensate, chloride, brine, and slurry piping systems within the process plant.
Special Info: Sacré-Davey Engineering reviewed the piping systems to identify leaks, wall thinning, vibrations, misalignment, missing supports and poor practices. A comprehensive list of recommended repairs and replacements was provided.
Pulp & Paper
No. 2 Paper Machine Fourdrinier Table Rebuild
Project Name: No. 2 Paper Machine Fourdrinier Table Rebuild
Client Name: Port Townsend Paper Corp.
Industry Sector: Pulp & Paper
Location: Washington, United States
Project Description: This project includes the detailed design for the No. 2 paper machine fourdrinier table rebuild at Port Townsend Paper. Sacré-Davey staff reviewed the documentation provided by the technology provider, IBS, and integrated the system requirements within the mill. We provided a scope of work construction package that described and detailed the multidisciplinary work and specific requirements for contractor installation.
Scope of Work: The SDE engineering team produced an IFC (issued for construction) package that included all work necessary to install ancillary equipment for proper operation of the rebuilt fourdrinier table. This included process, mechanical, electrical and instrumentation/control.
Challenges: Paper mill turnarounds are extremely important time periods each year for installation projects. As this project impacted a very important financial asset of the facility, Sacré-Davey was asked to carefully design around PM2's operations to make full use of the time period before and after the mill's outage.
A secondary challenge was utilizing the limited wet end spacing for installation of larger and more complex equipment configurations.
Solutions: As part of our scope of work packages, SDE deliberately separated the pre-outage work into its own standalone package, facilitating contractors to begin the construction/demo work weeks ahead of the turnaround. Additionally, SDE designed a more vertically integrated mechanical system that could be fabricated as a full system off-site and installed in place via crane.
Achievements: Sacre-Davey Engineering successfully compiled all aspects of the design packages utilizing 3D modeling software, multidisciplinary pulp and paper expertise, and mill management/operator communication to successfully install the fourdrinier rebuild.
RO Demineralization
Replacement
Project Name: Multimedia Filtration and Reverse Osmosis (RO) Water Demineralization Replacement System
Client Name: Port Townsend Paper Corp.
Industry Sector: Pulp & Paper
Location: Washington, United States
Project Description: Port Townsend Paper had an in-situ separate train demineralizer water system feeding three separate boilers. Their system was old, unreliable, and prohibitive repair and maintenance costs facilitated a full system replacement. A technology provider was selected to provide a single pass system capable of flows from 500 to 800gpm. Sacre-Davey’s primary scope of work was integration of these units within the mill and detailed design for ancillary system requirements.
Scope of Work: The SDE engineering team produced an IFC (issued for construction) package that included all work necessary to demolish existing systems and install each new equipment skid (activated carbon filters, sand filters, and reverse osmosis) for proper operation of the demineralization process. This included process, mechanical/piping, structural, electrical and instrumentation + controls.
Challenges: Two adjacent rooms were selected by the mill to place the equipment skids as the existing system was still in operation. Site investigation confirmed that the rooms were very small for the size of the skids and that they had very limited structural support. Limited room meant additional pipe routing and instrument location challenges for the engineering team.
A secondary challenge was to provide an in parallel commissioning, start-up and “hot” switchover plan.
A secondary challenge was utilizing the limited wet end spacing for installation of larger and more complex equipment configurations.
Solutions: SDE’s solution was two-fold: provide an accurate and representative 3D model to isolate and identify interferences and relocate smaller equipment to adjacent unused areas maximizing room spacing. Helical piles were specified to support the 100-year-old floor and where piles could not physically be installed, structural foam was employed.
Additionally, SDE utilized previous hot switchover experience to schedule tie-in activities and provide operations with detailed step-by- step procedures.
Achievements: Sacre-Davey Engineering successfully completed all aspects of the design packages utilizing 3D modeling software, multidisciplinary industrial boiler feedwater expertise, and mill management/operator communication to successfully provide an integration solution for the demineralization replacement system.
65MW Cogen
Turbine
Project Name: 65MW Cogen Turbine
Project Description: Mechanical and process design for 65 MW steam condensing turbine with 3 extraction stages, including extensive modifications to steam distribution network throughout the plant and rationalization of steam end use. Our pulp and paper client identified an opportunity to optimize steam resources and increase revenue by installing a 65 MW condensing steam turbine/generator set. Mill wide steam consumption was reviewed and maximum efficiency gained by converting several turbine drives to electric; optimizing steam generating boilers; and installing the turbine generator & associated equipment.
Scope of Work: The scope of the TG project involved turbine, new condenser, new mill-wide steam piping, cooling towers, electrical switchgear, controls, engineering and implementation assistance.
SDE and Binnington Development Corporation collaborated to provide definition level engineering services to develop preliminary process design and cost estimate for this project. Work included purchase and installation of a TG set and ancillary equipment; process control systems; grid interconnection and protection, major switchgear and substation. Work was completed on an EPCM basis for the equipment specification & procurement, detailed process, mechanical, electrical, instrumentation and controls engineering, as well as ongoing project/construction management support.
