THE TOWER 13 HAS THREE FOLD OUT LEGS 15,EACH EQUIPPED WITH A FOOTING ASSEMBLY 17. THE TOWER 13 IS SUPPORTED FOR ROTATION BETWEEN A HORIZONTAL STOWED POSITION AND A VERTICAL POSITION FOR DEPLOYMENT, ABOUT THE BARGE 11, BY A PIVOTAL CONNECTION 19. THE TOWER IS ALSO SUPPORTED IN A TRAVELLING FRAME 20 WHICH HAS CONCAVE SHAPED ROLLERS 21 WHICH TRACK EACH CHORD OF THE TOWER 13, ALLOWING THE TOWER 13 TO BE MOVED UP AND DOWN RELATIVE TO THE BARGE 11, WHEN THE TOWER IS BEING DEPLOYED. IN THE VERTICAL POSITION THE TOWER 13 IS RECEIVED THROUGH AN OPENING WHICH EXTENDS THROUGH THE DECK TO THE HULL OF THE BARGE 11. A CENTRAL CUT OUT PORTION 33 EXTENDS FROM THE STERN OF THE BARGE 11, TO THE OPENING, TO PROVIDE A PATHWAY FOR THE TOWER 13 AS IT IS ROTATES BETWEEN THE HORIZONTAL AND VERTICAL POSITIONS. THE BARGE MAY BE JACKED UP CLEAR OF THE WATER, AND MAY BE SEPARATED FROM THE COLUMN TO ENABLE THE EMBARKING THEREFROM.(FIG 1) |
