Cel It is aim of this development project to prove the economic and technical viability to utilize marginal gas fields and associates gas for power generating purposes.Platform concept.According to the bordeline conditions mentioned under para.2 we have found out, during the concept phase, which ended in april 1977, that a floatable jack-up platform carrying the power station would be the most suitable solution.It is foreseen that the platform will be set up on a lower structure which has specially been designed according to the prevailing local conditions.It was found that the most economic position for the joints should be approx. - 10,0 below the surface.The overall dimensions : 66 x 66 x 24 mLoad carrying capacity for accommodations and equipment: 9,000 Tons Proposed location : southern and central north seaThe special devices of the jack-up system permits to make the set -up during 70% of the prevailing weather conditions during the summer.Power stationDuring the conception phase we have investigated the following power generating cycles:Gas turbines onlyCombined cycle with waste-heat boilerPressurized furnace boiler with gas turbine.It was found out, the combined cycle with waste heat boiler produced the lowest generating costs up to 400 km distance from the coast. This holds true for primary energy prices who are within the production costs and return expectations of the oil companies providing the gas.Energy transfer.For technical reasons, the energy transfer can only be achieved by means of a high voltage direct current system. Only this system permits the transport of electric energy over large distances by sub sea cables.The evaluation of already existing cables placed on the surface of the sea bottom revailed the relative sensivity against damage of the so placed cables. Subject of the study is also to evaluate existing trenching methods in view of their performance and to propose eventually corrective action.For reasons of economic comparison we have taken the "bundesrepublik deutschland" as a significant area of consumption . Price of electric power and primary energy costs in this region are taken as valid for this calculation. Within the framework of this study the conditions of existing marginal fields are investigated and the possible prices for the supply of n. G.Are calculated. Operating time on one location in a marginal field with a production of approx. 300 to 600 mw is assumed to be 5 to 7 years.
