Our Client required a on-pond asset for winter berthing and maintenance activities for their dredge. The maintenance dock provides an interface for shore equipment like mobile cranes and refueling capacity for work boats. The dock was designed to accommodate the rapid elevation changes of the tailings pond. Engineering, Procurement, and Fabrication were all performed by GN2. Fabrication of the asset was completed in Q4, 2022, within budget of $9M.
Scope Summary
Refined early engineering concept with the Client to provide a fit for purpose solution with various cost saving considerations while maintaining an aggressive project schedule. Performed stability and mooring analysis for the maintenance dock design and its various operating configurations. Completed detailed engineering for the entire maintenance dock (all disciplines). Prepared Modular Work Packages (MWPs) for shop fabrication to minimize required onsite work. Shop fabrication of the Project was directly supervised by GN2. Developed Material Requisitions (MRs) for major equipment purchases. Completed Procurement and Expediting for the dock equipment purchase and shop fabrication. GN2s supply chain team managed twenty-seven different Purchase Orders for the project. Prepared Engineering Work Packages (EWPs) for on site dock assembly, launching and mooring.
Challenges / Innovation
To ensure required maintenance activities could be completed, GN2 developed a custom articulating gangway to accommodate rapid pond elevation changes while maintaining access from shore. The project was schedule driven. GN2 provided detailed engineering, procurement, and off-site fabrication within a 12-month window. Through rigorous challenging of the Client design criteria GN2 was able to provide a design that minimized the size of the maintenance dock and replaced diesel generators with permanent low voltage power. The addition of permanent low voltage power increases the reliability of the asset and was able to be delivered without schedule delay to the maintenance dock. GN2 utilized a decommissioned Client asset by salvaging the modular floats from another floating platform. No additional long lead modular floats where required for the project avoiding potential schedule delay. The reduced size of the dock simplifies execution of launching the asset and the future dock relocations. GN2 was able to prioritize long lead items by determining critical design criteria for major equipment and quickly pivoting to maintain schedule, even among global supply chain challenges.
