Installation of Wellhead Access Deck

The Redevelopment of the Tyra East and West fields included a change-out of the existing wellhead platforms while retaining the jacket structure. 

To safely support the well conductors during the change-out operation and ensure satisfactory permanent support conditions for the conductors, a new deck structure was to be installed.

This structure was termed “wellhead access deck” and was installed and assembled in three prefabricated sections and infill pieces.

The installation of the wellhead access deck was a demanding and challenging job, which was carried out using our special team of rope access technicians along with a larger crane setup, carrying it from the vessel to the position underneath the platform.
