Abstract
An improvement in a side element of a drilling template for wells at sea for extracting hydrocarbons, wherein the side element is connected to a central section of the drilling template and projects horizontally out therefrom. The side element is arranged to carry equipment of various types. According to the invention the side element comprises a coupling section for releasable connection with a coupling section of the equipment.
Claims12
A side element of a drilling template, comprising:
- a first end and a second end;
- a hinge section (2) at the first end, the hinge section comprising flanges (4) with mutually coaxial, through-going holes;
- a hinge pin (6) extending through the through-going holes, the flanges and through-going holes adapted to link the hinge section to a central section of a drilling template via the hinge pin;
- the hinge section having a contact section (8) with a contact surface (10) for abutment against a corresponding contact section of the drilling template;
- a receiving section (14) at the second end, the receiving section comprising a truncated cone-shaped funnel section (16) diverging upwards when the receiving section is in a normal horizontal, upright position;
- an adapter, with first and second connection sections, the first connection section for releasable connection with the receiving section and the second connection section for releasable connection with drilling equipment;
- and
- at a narrow, lower end of the funnel section, a tubular section (18) with inwardly projecting claws (22), the claws being movable radially inwards towards a longitudinal axis of the funnel section to releasably engage the adapter,
- wherein the hinge section further includes a disc-shaped accompanying element secured by the hinge pin and positioned to prevent the receiving section from pivoting below a horizontal line described by the normal horizontal, upright position.
