The Deliverables Large Waves Due To Coastal Storms (wind-waves) Or Tsunamis (in The Form Of Solitary Waves) Will Be Simulated Within The Multi-hazards Simulator (mhs) Using A Wave Generator. The Wave Generator Consists Of A Flat “paddle”, Which Is A 1.5 M Wide By 1.5 M Tall Rectangular Plate That Is Hydraulically Driven Back And Forth By A Piston To Generate A Series Of Water Waves. The Wave Generator Action Is Controlled Such That Various Wave Trains Can Be Created, Regular Or Random, With Controlled Wave Periods And Amplitudes. Convenient Software Included With The System Is Used To Specify The Wave Train. The Control System Also Utilizes Water Wave Sensors Placed Onboard The Wave Generator And Within The Mhs To Adjust The Piston Action In Real-time. This Should Enable The System To Dampen Reflected Waves While Continuing To Generate The Desired Wave Train. The Mhs Flume Is Built With A Concrete Wall On The South Side And As A Steel Frame Construction As The North Wall, With Glass Panels. The Flume Has A Total Length Of About 29.5 M From The East End To The West Wall Which Delineates The Outlet Wall, A Cross Section Of 1.5 X 1.5 M, With A Maximum Still Water Depth Of 1.2 M. The Flume Is Serviced By High-capacity Pumps (2 X 0.5 M3/s = 1.0 M3/s) That Draw From A Large (300 M3) Water Storage Reservoir Situated Below The Flume Bed. The Section Where The Wave Maker Will Be Installed Has A Strong, Reinforced Concrete Wall On Both Sides. Refer To Figure 1: Multi-hazards Simulator. For Further Information Regarding The Installation Site And Current Infrastructures, Please Refer To Appendix L – Investigation And Recommendation Study. The New Wave Generator System Must Be Manufactured And Delivered As Soon As Possible. Therefore, The Immediate Planning For The Wave Generator System Must Be Made In Coordination With The Users And The University Of Ottawa Facilities Team Such That The Construction Works Which Is Required For The Installation To Be Also Carried Out To Manage Potential Interfaces And Dependencies Immediately After Contract Awarding. Statement Of Work 1. Background 1.1 - Requirements-specifications And Environment The Wave Generator System Will Be Located At The East End Of The Mhs Flume. The System Shall Be Able To Generate Waves, With And Against The Main Current /flow Direction. At The Same Time, The Wave Generator Must Be Equipped With An Active Absorption System To Avoid And Significantly Reduce The Occurrence Of Wave Reflections In The Test Section Of The Flume. Ideally, The Wave Generator Will Be Driven By A Servo Drive. It Is Expected That The Actual Stroke Will Be On The Order Of 1.8 M (+/- 0.8 M) And A Usable Stroke On The Order Of 1.6 M (+/- 0.8 M). The Manufacturer Should Provide The Performance Curves For The Wave Generation Capabilities Within This Specific Flume. The Wave Generator And The Actual Wave Board Motion Will Be Controlled Via An Included Software (for Windows). The Actual System Of The Wave Generation (wet Back Or Dry Back) Can Be Chosen By The Proponent As Long As All Given Specifications Are Met. The Flume Is Equipped With A Raising Gate Located At Its East End. Behind It, The Flume Discharges Into A Relatively Opening (drain) Into The Underfloor Reservoir. Alternative Tenders For Different Systems Will Be Accepted. The Wave Generator System Must Be Manufactured And Delivered In Conjecture With Of The Actual Process Of Building The Sediment Recirculation System (built By The University Of Ottawa) And Seismic Table (future Rfp) Components. The Wave Generator System Will Be Installed And Put In Operation As A Coherent System (including Software And Control System As Well As An Independent Data Acquisition System) By The Supplier According To The Specifications Provided Below As Soon As The Building Process Of The Mhs Flume Has Advanced Far Enough To Allow These Steps. Wave Characteristics The Specification Of Wave Parameters In Order To Define The Necessary Performance Of The Wave Generator In Terms Of Wave Board Stroke, Velocity And Acceleration Is Avoided Herein By Intention, As These Actually Depend On Several Factors, Such As The Underlying Wave/wave Theory Or Remaining Reflections From The Flume (nevertheless Reflections Will Be Avoided By The Use Of Wave Absorption System). Instead, The Minimum Requirements For The Wave Generator Performance Are Defined Directly To Limit The Wave Generation Capacity From The Beginning. The Manufacturer Is Expected To Confirm The Best Technical Solution At Least For Those Requirements Or Even Beyond And Comment On The Most Critical Aspects In Terms Of Electrical Power Consumption And Costs. Any Suggestions For Possible Alternatives, Which Reduce Purchase And Operating Costs, Are Expected. 1.2 - Technical Requirements: 1.2.1 - The Maximum Water Depth For Wave Generation Will Be 0.9 M And The Minimum Water Depth For Wave Generation Will Be 0.3 M. 1.2.2 - It Is Anticipated That The Wave Generator Will Be Running For About 1,000 Hours Per Year With Water Depths Between 0.5 M To 1.0 M In Most Cases. 1.2.3 - The Maximum Duration For Continuous Wave Generation Must Not Be Less Than 4 Hours And Need Not Be More Than 10 Hours.
