“…Coastal structures are usually very expensive, and the type of construction strongly depends on the natural features of the location, among which is the geological structure and consequently on the geotechnical features of the seabed [1,2]. In recent decades, the methods of undersea research have improved significantly in the world, especially due to development of offshore constructions [3,4].…”

Near Omišalj on the island of Krk, where the construction of a pier for liquefied gas is planned, hydrographic measurements revealed three shoals at depths of 13.5 and 13.6 metres. For the safety of navigation, the seabed had to be deeper than 15.4 m. The geological fabric of the seabed was determined using a hydroacoustic survey and remote operating vehicle. Shallows are formed in a solid carbonate rock mass. Special technology of excavation without blasting was applied. 11,000 m3 of rock mass was excavated which was deposited nearby. The seabed habitat with an area of about 12,500 m2 was changed.

“…Besides these prominent examples, some research has also been devoted to the employment of VLFSs in the construction of floating harbors in the ocean, serving as logistic hubs (Tsinker, 1997(Tsinker, , 2004Kim and Morrison, 2012). Like floating airports, these face the challenge that the dimensions of typically employed landbased infrastructure exceed the dimensions of anything that has been built for long-term offshore deployment so far and that the environmental conditions of offshore locations generally impose restrictions on the operability of such infrastructure.…”

The design of a modular floating multi-purpose island inherently involves interaction within a group with a large range of backgrounds such as engineering, architecture, sociology, climate modeling, and more. A heuristic design approach was adopted for future island developers to make a first conceptual design. Four major design considerations were distinguished to discretize the design space: module size, module shape, module principle, and module connection and mooring. For each consideration a set of evaluation criteria were defined. This article describes the heuristic conceptual design procedure that was applied to the design of a modular floating island for offshore energy, offshore accommodation, aquafarming, and offshore transport and logistics. Two reference installation scenarios with a different respective focus of functionality, located in the North Sea and in the Mediterranean Sea, were created as a basis for the design. The first step of the design procedure consisted of a participatory process involving stakeholders and experts to rate design options for each category of design considerations based on the evaluation criteria and with regard to the installation scenario. As a result, all design configurations could be associated with an overall rating. In a second step, the most favorable designs identified during the participatory design procedure were investigated numerically to assess force distribution throughout the island when exposed to wave and current loads. The numerical results indicate that contrary to initial estimates during Phase 1, wave forces on an island consisting of quadrangular modules do not significantly exceed those experienced by triangular base shapes. As quadrangular modules can be shown to provide a higher Ground-Space-Index, this gives them a distinct advantage. As a result of the design process for this application, a barge-like, square structure with a base size of 45 m was chosen as the base module.

Coastal zones represent vital international issues for environmental and sustainable development. Most coastal developing countries mainly depend on the limited coastal resources for their economic development. The promising region of the Northwestern coast of Egypt has attracted massive investments. The main objectives of this present research are: selection of most suitable sites for constructing ports in this area based on a number of environmental criteria and to assess the suitability of the proposed site. Factors used in this study include natural land/marine hazards/factors man-made facilities. Materials used include: multispectral satellite images, digital elevation models, topographic maps, Admiral marine maps, in addition to field survey of the sea depth. Spatial modeling is performed using the spatial analyst module for port site selection and assessment. A total of 62 locations are identified and classified as suitable for positioning a port. All identified areas extend from west of Marsa Matrouh to East of Negeila and record a suitability values from (Good) to unsuitable. Index Terms-Site selection, ports, northwestern coast of Egypt, remote sensing and GIS, land criteria, offshore/inshore criteria.
