ABSTRACT The aim of the present paper is to investigate the feasibility and the type of method for oil production in the offshore area of Katakolo in western Greece. The strategic development of oil production analyzed herein is based on the following five factors:social conditions of the area, geological- geophysical conditions and oil deposit, socio-economic impact and financial considerations of the three proposed methods for oil production, methods for oil storage and transportation and, evaluation and comparison of the three oil production methods. Based on the proposed strategic framework and the results of the associated analysis, it can be stated that this effort is the first one to present the most efficient approach for developing the oil field in Katakolo, taking into account environmental constraints, socioeconomic factors and safety issues. INTRODUCTION The continuous increase of energy demand around the world stimulates interest in finding new oil fields. Oil exploitation represents a significant component of the strategic plans for energy requirements in many countries. While oil remains the dominant source of energy in Greece, exploration till now has been very limited and only in northern Aegean a low oil production exists since 1981. Greece can be considered the least oil explored country in the eastern Mediterranean region. The legal framework being applied since 1995 has led to this stagnation. The removal of this weakness was imperative. The enactment of the new Law 4001/2011 in combination with the preexisting one formed a new flexible legal framework. To overcome the stagnation, Greek authorities focused their efforts on an aggressive oil exploration campaign starting from non-exclusive seismic surveys in the Ionian and southern Cretan Sea and introducing three areas in the procedure of open door (MEECC, 2011). This procedure can be applied in Greece because the areas are permanently available, as they belong to the state.

ABSTRACT In this paper, the numerical investigation of a high deck open quay wall structure, supported on piles partially embedded in a porous embankment is presented. The governing equations solved are the Reynolds Averaged Navier-Stokes (RANS) equations of motion, while the two equation RNG turbulence transport model is applied. Parametric studies have been carried out for two different wave lengths, two structure clearances and two inclinations of the porous embankment. The forces exerted on the piles and on the underside of the deck of the quay structure due to waves are computed. The forces exerted on a single cylindrical pile computed with the present numerical model are compared with those calculated through the analytical equation of Morison. The computed pressures on a deck structure are compared with the experimental results of the investigation of other researchers. INTRODUCTION Quay walls are marine structures, generally parallel to the shore. They are broadly classified into two main types, quays with solid (closed) construction, like sheet and gravity walls with a solid vertical berthing face, and quays with an open construction, having a suspended deck supported on piles (British Standard's Institution, 1988). The type of the open quay construction is not in common use worldwide. However, in cases where there is need for wave absorption or there are favorable ground conditions, the open quay is preferable against the solid one (PIANC, 1997). The presence of the porous rubble slope in the structure of the open quay is responsible for the wave energy absorption and the reduction of the wave reflection. Furthermore, in ports with poor near surface soils but with good end bearing capacity for piles, an open pile supported quay would be most economical (Department of Defense, 2005). However, an open structure is proved to be more delicate than a solid one.
