Offshore drilling and a configurable support structure for the same

A method of constructing and/or processing one or more offshore surface-wells, the method comprising constructing and/or processing an offshore surface-well through a well center of a well processing station, the surface-well comprising a conductor having an upper part including an upper end, and said method comprising the steps of:

• providing a bottom supported configurable support structure for the well processing station, the configurable support structure including support structures extending to the seabed and supporting a wellhead platform with the configurable support structure;
• constructing and/or processing a first surface-well through the upper end of the conductor at a second position,
• moving the upper part of the conductor to a first position of the conductor,
• producing from or injecting into the first surface-well through the upper end of the conductor at the first position;
• and
• the method further comprises applying one or more counter forces to one or more other conductors in a direction opposite the movement of the conductor between the first position and the second position by at least one support element when moving the conductor from the first position to the second position, the one or more counter forces reducing the impact of a movement force on a main structure supported by the configurable support structure, where the movement force is a force acting on the conductor due to the conductor being moved between the first and the second position.

A method of constructing and/or processing one or more offshore surface-wells, wherein the method comprises progressing a plurality of surface-wells towards completion by:

• providing a bottom supported configurable support structure for a wellhead platform, the configurable support structure including support structures extending to the seabed and supporting a wellhead platform with the configurable support structure;
• moving an upper part, of a selected one conductor of a surface-well, from a first position to a shared second position of the upper end and carrying out one or more well constructing and/or well processing tasks through the upper end of the selected one conductor to at least partly complete the surface-well of the selected one conductor,
• moving the upper part of the selected one conductor from the shared second position of the upper end to a first position of the upper end after at least partly completing the surface-well, and
• repeating these steps for one or more additional conductors,
• wherein the method further comprises applying one or more counter forces to one or more other conductors in a direction opposite the movement of the selected one conductor between the first position and the second position by at least one support element when moving the selected one conductor from the first position to the shared second position, the one or more counter forces reducing the impact of a movement force on a main structure supported by the configurable support structure, where the movement force is a force acting on the selected on conductor due to the selected one conductor being moved between the first and the second shared position.
