1 Marine 15 Planning & Infrastructure for Marina Development

2 Who is this Pompous American? Jesse Ellenz Vice President of Special Projects

3 What Makes Him So Special? Nothing Not a PHD Not a Professor Not an Engineer Not even a professional speaker

4 Now that he is done patting himself on the back what is in this for me? Hopefully insights to the concepts: All the good sites for marinas are taken Site Specific Design Solutions Some places where people want to boat are just not conducive to permanent infrastructure Life Cycle Costs vs. Initial Purchase Price Vessel Mix is changing faster than replacement schedules People want to do more than boat on the water Marine infrastructure is more than just piers and pontoons Finally. Balance

5 All The Good Sites for Marinas are Taken

6 St George, Floating Wave Attenuator Products: Unifloat Curved Attenuator Services: Design/Supply Supervised install Scope: Project design and manufacture

7 St George, Floating Wave Attenuator

9 Site Specific Design Solutions

10 Round Butte Dam, Floating Platform Products: Custom floating platform Services: Design/Supply Supervised install Scope: Platform design and manufacture

Round Butte Dam, Floating Platform Project Details: Floating platform is submerged 20 below the surface and supports a superstructure that is over 40 tall and over 2,000,000 lbs of structural steel

11 Round Butte Dam, Floating Platform Project Details: Floating platform is submerged 20 below the surface and supports a superstructure that is over 40 tall and over 2,000,000 lbs of structural steel Platform is made up of 40 match cast floats Over 330 vertical through-rods were placed to tie the steel structure into the platfrom Individual modules have a complex series of mesh, special spiral rebar and steel bearing plates for DYWIDAG reinforcement

15 Life Cycle Costs vs. Initial Purchase Price How do you design a Harbor to survive a Tsunami?

16 Crescent City Harbor, California Products: Unibolt Concrete Floating Docks Wave Attenuator H dock Services: Design/Supply Scope: Dock system and anchorage design and manufacture

Crescent City Harbor, California Project Details: Designed to be a tsunami-resistant marina 30 pile, driven 35 feet into bedrock; supported by 600 800 lb.

17 Crescent City Harbor, California Project Details: Designed to be a tsunami-resistant marina 30 pile, driven 35 feet into bedrock; supported by lb. pile guides Piles are designed with 25% reserve 400 long attenuator dock features 39 x 16 x 7 modules with 1 gap between modules. Each module weighs 160,000 pounds Ballast tubes were placed in the corners of individual H-dock modules for trimming the system

21 St. Paul Small Boat Harbor, Alaska Project Details: Floating docks and boat ramp designed to withstand severe environment and seasonal use Floats are hinged to facilitate removal System is held in place with a gravity anchor system utilizing concrete anchor planks and chains with clump weights All boat ramp components are posttensioned

22 St. Paul Small Boat Harbor, Alaska

23 Vessel Mix is changing faster than replacement schedules What do you do when the US Navy Calls you and tells you that they want to have a way to moor all different sizes of boats and have the ability to reconfigure the moorage at a moments notice?

24 Navy Utility Floats, Washington Products: BMI Custom Concrete Dock System Services: Design/Supply Scope: Dock system design and manufacture

up to 600 long One utility trench runs the length of the module and two transverse trenches for large

25 Navy Utility Floats, Washington Project Details: Designed to replace steel utility floats used by the U.S. Navy based on the Unibolt design 60 modules can be used individually or connected to form configurations up to 600 long One utility trench runs the length of the module and two transverse trenches for large shore power cables and hoses Steel channels on non-shipboard side allow pile collars to be detached and adjusted

26 People want to do more than boat on the water Are there other activities that could help enhance the experience offered at your marina?

27 Floating Swimming Pool, Chicago Products: Custom floating platform Services: Design/Supply Supervised install Scope: Platform design and manufacture

28 Floating Swimming Pool, Chicago

Floating Swimming Pool, Chicago Project Details: Concrete Floating platform to support a new floating pool. The platform measures 85 by 40 with a 9 wide deck that surrounds the pool.

29 Floating Swimming Pool, Chicago Project Details: Concrete Floating platform to support a new floating pool. The platform measures 85 by 40 with a 9 wide deck that surrounds the pool. All utilities are routed internally to provide a clean deck and all treated lumber is concealed with a polymer cover. The pool sits snug within the platform s hole and is designed to float independently. The platform was engineered with the buoyance of the pool in mind. When filled, the pool sits flush with the deck of the platform. When the water is drained from the pool, the insert is free float at its natural level in the water beneath it.
