Covering tent for surrounding a wind turbine at its base during a grouting operation

A method for arranging a sheltered space around a base of an upstanding structure in fixed location on a support surface, the base having a perimeter, comprising:

• providing a tent for forming the sheltered space comprising:
• a covering having a top edge arranged to follow the perimeter of the structure base at a predetermined height above the support surface and a bottom edge arranged to define an outer periphery of the covering in an installed condition surrounding the structure base;
• an attachment arrangement for attaching the covering to the structure at its base including a base strap arranged for wrapping about the perimeter of the structure base at the predetermined height above the support surface;
• the base strap having an outer face with a first attachment member;
• the attachment arrangement including a second attachment member along the top edge of the covering that is cooperative with the first attachment member so as to fasten the top edge to the base strap in a manner following the perimeter of the structure base;
• attaching the base strap to the structure at the predetermined height with an inner face of the base strap facing towards the structure so that the base strap forms a closed loop about the structure;
• attaching the top edge of the covering by the second attachment member to the base strap at its first attachment member so as to wrap the top edge about the perimeter of the base of the structure thereby locating said top edge at the structure;
• arranging the bottom edge of the covering at a location spaced outwardly from the structure so as to define the outer periphery of the covering;
• whereby the sheltered space is formed around the base between the top edge of the covering which is attached to the base strap around the perimeter of the base and the outer periphery of the covering.
