Hyper Large Polymeric Floating Structures, to host complete self-sufficient living places

Paul Gaiser, Founding President (TETHYS TECHNOLOGIES Brazil)

VLFS designs have traditionally considered steel and/or concrete as essential materials. However, a new specific composite of initially non suspected materials for this application, such as polymerics EPS, HDPE, UHMW-PE and bamboo, shows that, if disposed correctly, it can surpass them in cost, stability, durability, safety and performance.

With this possibility, we developed a project of a single floating body, 1.200ha large, 24m of minimum base height (“thickness”), 7m draft, moored by four special steel towers, with 350m in diameter, one with 250m and three with 100m in height, all deployed permanently at seabed. This mooring system also absorbs hydro-elastic effects, and it’s also used for hybrid energy storage and generation, with hydro-pumped and gravity-based energy converters. Each tower is wrapped with the composite in a conical shape, for a larger area to withstand dynamic mooring forces. Empirical tests suggest resistance against tsunamis, hurricanes, fires and ship shocks.

The cost of usable m2 shall be around US$ 2,500.00, and general constructions shall have a reduced cost due to the facilities it provides. The visual format mimics natural islands, has an expected durability of 500 years for the structure, and has low maintenance costs. As the high density Expanded Polystyrene (EPS) is the most bulky element, it can be produced nearby reducing transportation costs. The fixings of the composite elements follow a patented technique. New patents linked to the project will allow the installation of 34.000 homes and other buildings, for the infrastructure of a self-sufficient city, in compliance with the 17 Sustainability Objectives of the United Nations (UN). Paradoxically, this project can make the oil industry become the protagonist of the most ecological solutions to the current environmental and social threats on Earth.

Paul Gaiser, Brazilian, graduated mechanical engineer, researcher for mechanics, physics and new materials, manages developments of special composites to build floating vessels. As ex F1 and off-shore powerboat racing pilot at world championships, the sport gave him full intimacy with all kind of water bodies. Member of FLOATING SOLUTIONS Society, Singapore, and founder president of TETHYS TECHNOLOGIES LTD, which joins a group of scientists and technicians dedicated to future floating cities related issues, like hydrodynamic drag, natural avoidance of biofouling barnacles, new sustainable energy sources, new housing construction materials and methods, new public transport modals, new humanized systems to breed animals, new water distillation equipments and new dry toilets.

He believes that challenging the solutions for big problems and threats, simplicity and good will are the keys for big results, also that VLFSs are the best showcases to it.
