It shows that offshore investment cost might increase from 1800 to 2878 D /KW as the distance to the coast. Installation and grid connection costs are those most affected when offshore wind farms are located further from the shore. At larger distances installation costs increase because of the greater travelling time needed from the holding port to the site. In addition, weather conditions usually worsen further offshore making installation more difficult. Another
cost affected when the distance to the shore increases is the export cable, which connects the wind farm to a suitable connection point on land. The factors influencing cable costs are cable size, sea bed conditions and the possible need for transformer stations
