2. Content design issues design proposals / features calculations costs other potential usages

3. Design issues JT service Oy would benefit from design solutions for: a lighter bigger boat/float an all round profit bringing easier to store cheaper and easier ways for transportation expand customer base by expanding its services

4. Design proposal 1. New materials buoys manufacturing: Syntactic Foam:

5. Qualities Light, strong, it doesn’t need special tooling Controlled buoyancy Wide range of specifications e.g. stronger epoxy outer layer outside, lighter inside Very stable qualities and a long life It can machined with other materials: plastic skin or aluminium extrusions

6. Already used in marine applications

7. Highly taylorable High-impact and abrasion resistant coatings Available in high- visibility orange or yellow

8. Shape

9. Modularity 2 separate pontoons Sliding structure to be used as a platform Modular sizes; easy to customize dimensions Easy to transport and store Easy to assemble on site Smaller winches can handle the assembly

13. Some calculations For a length of 9m a width of 1.5 meters the combined weight of 2 pontoons is only approx. 500kg.( water displacement=27cubic metres The capacity is of a minimum 20 tonnes The platform weight (bridge structures) Aluminium with steel grade strength will make the platform lighter and stronger: under 100kg

14. Some basic structures

15. Costs Manufacturing : syntactic foam: approx. 16 €/kg Tooling (manufacturing hire facilities + syntactic foam ) = approx 10,000€ Aluminium extrusion ramps + platform (manufacturing hire facilities + aluminium)= 5,000€ Design work: 200 hours @ 6,000€ Patents: 3,000€ Engines: 2x 14,000€ = 28,000€ Other costs (transport, advertising): €2,000 TOTAL per item = approx. 54,000€

16. Other potential usages Dredging: cutting reeds Ferry service: for transporting vehicles (cars, motorbikes,…) Hiring / Loan service Scuba diving platform Bridge repairing
