Abstract:
Continual sea waves power generation systems and methods comprising one of the arrangement system of the sea waves devices by installing diagonal shape line up arrangement of devices (6to17) and installed on the seabed. The sea wave (1) blowing (5) one by one paddle of the each device (6to17) due to diagonal shaped line up arrangement, so the sea wave (1) reach final state, the sea wave (2) start its blowing work and this cycle stay on continue for power generation. Thus seriatim sea waves harnessing process stay on without interrupt. According to tides the crest of the sea waves up and down, so paddle of the similar leveled Fig. 14(4) of each automatic tower stay on opposite of the sea waves by automation, and thus the harnessing process of the sea waves stand continues, within low, medium and high tides, for grid quality power generation.

The invention further relates to a wind turbine (1) comprising the nacelle (2), a wind park comprising a plurality of wind turbines and methods.
Abstract:
A method and system for installing a site-deployable wind turbine offshore. The wind turbine can be substantially assembled onshore and includes a floating structure and a tower that is extendable at the installation site. A pivoting system can be configured to couple the wind turbine and turbine blades to the extendable tower in an onsite deployable configuration. After the wind turbine is delivered to an offshore location, the wind turbine is deployed and the extendable base and pivoting system can be made to deploy the wind turbine and turbine blades into functional positions such that the wind turbine can begin generating electricity.

Abstract:
The present invention relates to a tower preferably for a wind turbine, the tower comprising a number of horizontally disposed tubular tower elements each preferably comprising one or more first wall segments having a substantial rectangular projected shape one or more second wall segments having a non- rectangular projected shape. The first and optionally also the second wall segments comprising at least one bend along the vertical direction of the wall segment and defining two neighbouring flat panels, the bend being provided in a distance from a vertically extending edge of the wall segment so as to provide the wall segment a concave shape. The first wall segments and second wall segments are arranged neighbouring to each to each along their longitudinal edges so as to form a tubular structure. A tower according to the invention may provide an excellent platform for arranging a crane – or hoisting equipment in general – to the tower, both during set-up and maintenance of a wind turbine.
