Waterfront Development - International Marine Floatation


		Using both the mass and width of concrete sections, significant wave reductions can be achieved.

		All IMF wave attenuators are manufactured of structurally reinforced concrete and are monolithically cast in lengths up to 150 ft. and require no maintenance for the life of the structure.

		The benefits of the IMF wave attenuators are as follows: Fewer Anchoring Points - Structural concrete maintains geometric shape! Utilizing long structural concrete float sections, which will not bend, allows more accurate loading of the anchors or pilings and which can reduce the number required to hold the breakwater in place. Cleats and Bull-rails - Security that counts! Cleats, and when required, bull-rails, are bolted through 6" of reinforced concrete for unyielding holding power that does not weaken over time. Pile Rings - Options to meet your needs! IMF's preferred pile ring design for strength, simplicity, and dependability is through the float. When this method is not an option, external pile rings are fastened to the breakwater with embedded bolts engineered for the load requirements. Environmentally Safe - Cured concrete is inert, allowing the natural growth of flora and fauna to continue uninterrupted. Introducting the IMF “DEFENDER” (patent pending) In the past International Marine Floatation Systems (IMF) has produced pontoon type wave attenuators with and without concrete wing-walls or skirts of varying depths. All of these old style pontoons have performed adequately for short period wave conditions, however, we believe a good market would emerge for those well-located sites that require an affordable wave attenuator for a 5-second period wave. Our objective is to achieve better performance for less cost and for longer wave conditions. By “thinking outside the box”, we have developed a new concept that achieves the following: Unsinkable positive floatation wave attenuator (not the hollow vessel type) 100+ year lifespan Very low maintenance for the life of the wave attenuator Simple construction methods (no water tight compartments, hatches, etc.) 100’ – 300’ long one piece sections (dependant on the size of local facilities and delivery constraints) Scaleable for various long wave conditions 70% attenuation for a 5-second period wave Westmar Consultants Inc. www.westmar.com of Vancouver, B.C., Canada have conducted a 2D study of our new “DEFENDER”, indicating very good performance results.

		For comparison, a simple caisson would require a mass of 50 Tons per meter for a 5-second wave; our design would require 15 Tons per meter for .3 transmission co-efficiency. We believe the costs for the IMF “DEFENDER” concept would be as low as 50% of the simple caisson model. Contact us for more details.
