The document proposes two alternative solutions for a floating avenue at the port of Thessaloniki, Greece. The first alternative involves developing a large marina and tower, detached from the waterfront. The second alternative involves modules attached to the dock. The estimated costs are 180 million euros for Alternative I and 100 million euros for Alternative II. Construction would take 1.5 years and pay for itself within 3 years, while creating many local jobs.
This document discusses wave absorbing technologies developed by Offshore Energy Systems SA. It describes how wave energy is concentrated near the sea surface, so absorbing structures are needed there. The company developed Intense Floating Bodies carrying standardized, variably inclined wave absorbing cells that break incoming waves into smaller fields to reduce forces. Field tests of these wave absorbers and a wave energy exploitation apparatus were successful in Laurion. This led Offshore Energy Systems SA to offer a product range of floating, bottom-supported, and dock wave absorbers.
The document describes an offshore wave energy conversion system called WECO that uses an oscillating body column to harness wave energy and convert it to compressed air. The compressed air is then used to power air motors connected to electricity generators, forming basic production units. These units can be connected on floating platforms to form larger installations to exploit wave energy fields and integrate other renewable resources like solar, temperature differences, and wind via hybrid systems. The system allows for temporary energy storage in compressed air reservoirs and production of high quality electricity.
A Ddaskalakis AquacultureEngineering Technology Oct 19 17+10Antonis Daskalakis
The document discusses offshore fish farming using intense floatation technologies. It describes how moving fish farms to deeper waters provides benefits but challenges that require new integrated technologies. Intense floatation technology is proposed, which involves a main buoyant unit below the surface to reduce wave forces. Mathematical modeling is used to simulate intense floatation bodies in waves and calculate motions, loads and tensions. Design considerations are outlined for realizing intense floatation technologies through modular buoyant structures, mooring line blocks, and anchors that can withstand loads from all conditions.
The document describes the activities, products, and services of Offshore Energy Systems SA, including floating systems, bottom supported wharves on piles, wave absorbing systems, offshore energy systems, ship design and shipbuilding, port equipment, and research and development. Some key areas of focus and innovation are wave-absorbing systems, navigation and control systems for fast ships, ventilated hydrofoils, floating wind generators, and measuring wind potential offshore. The company aims to provide innovative solutions for environmental protection, financial, and energy crises through renewable offshore energy including wind and wave power.
Intense floatation and its applications in offshore structures and installationsAntonis Daskalakis
Intense floatation or otherwise tension Leg is a technology with widespread applications. This article, published in the official Magazine of Mechanical and Electrical Engineers of Greece describes some of these applications.
The development of offshore wind farmsat deep and very deep waters requires a carefull and systematic evaluation of the wind energy potential.
The following Technical Data Sheet describes our proposal

OFFSHORE ENERGY SYSTEMS-DUAL TYPE FLOATING WIND PLATFORM-UP TO 15 MW.pdfAntonis Daskalakis
The document proposes a dual type floating wind platform and anchoring system called "Design for Installation & Operation" to effectively develop offshore wind energy in Europe's open and deep waters. The proposed platform can be transported and installed with minimal support due to its self-transportable and self-installed capabilities. It uses a spar type design for transportation and intense floatation for operation. The proposed split anchoring system and mooring legs are designed to be within the capabilities of existing vessels. The platform aims to lower costs and simplify the logistical challenges of transporting, installing and operating large offshore wind platforms.

This document proposes integrating hydropower stations, floating solar panels, and wind turbines to create self-controlled smart grids in Greece. It outlines Greece's renewable energy goals and challenges integrating intermittent solar and wind power. The proposal is to install floating solar panels on existing artificial lakes and reservoirs to take advantage of existing electrical infrastructure and reduce costs. Combining the solar and hydropower with wind would allow controlling overall power production to match demand and provide stable, high-quality energy through "ring grids" or "virtual ring grids". Floating the solar panels offers significant potential capacity while improving panel performance and having environmental benefits compared to land installations.

The document proposes using a large anchored balloon to capture oil flowing from the damaged Deepwater Horizon wellhead underwater. The balloon would not fully seal the wellhead. Oil rising into the balloon would be pumped through a flexible pipe to a storage facility at the surface. Calculations using estimated well data show this may allow continuous capture of the oil flow. The concept requires more analysis and testing by engineers familiar with the well characteristics to evaluate feasibility. Key challenges include ensuring the pipe flow rate matches the well flow rate and preventing gas hydrate formation.
