Description

  The present invention relates to a floating environment observation apparatus installed on the ocean (at sea).

  In recent years, the need for offshore wind power generation, one of the renewable energies, has increased. In order to install this offshore wind power generation facility, it is essential to understand the wind conditions at the installation site. In addition, from the viewpoint of environmental protection, it is essential to understand the ecosystem where the offshore wind power generation facilities are installed.

  Under such circumstances, conventionally, aerial surveys from land and marine surveys by ships have been performed. For example, as shown in FIG. 11, when the air is observed from the land, it is based on radar or visual observation, and the observation range is limited, and it cannot be said that the survey is accurate. In addition, when a ship is taken out and surveyed in the sea, the survey is usually conducted only a few times a year, and this case is also not an accurate survey. Moreover, the movement of the ship affected the behavior of marine organisms, and it could not be said that the natural state was accurately investigated. Furthermore, surveys by ship were not easy because of the influence of weather and personnel.

  In addition, as an observation device for grasping the wind conditions on the ocean, for example, a main pillar, a boom having a boom body extending laterally from the main pillar and having a flat cross section in a direction perpendicular to the longitudinal direction, and a boom tip There has been proposed a tower-type observation tower for measuring meteorological data on water having a measuring instrument for measuring meteorological data (see Patent Document 1).
