Abstract
An elongated hollow tube 2 is secured to the top of a pile driver 1, and the assembled unit is lowered to the head of an anchoring pile 12on the sea bottom via spaced guide rings 13 on a submerged tower 10. The flexible hose string 5 for conveying hydraulic, electric, pneumatic, etc. power and control to the pile driver is accommodated in a loop fashion within the tube 2 via a weighted and floating pulley(s) 7, and feeds out during the lowering of the unit through guide rings 13 spaced on the tower over a pulley 4 mounted on a detachable surface ring 3. The various hoses and cables in the string 5 are maintained in a parallel relation by periodic clamping means 14, and smooth surface reel winding is implemented by periodic spacers 26 secured to the outboard tension cables 15, 16 in the string.
