    摘要: Method of erecting a minimal structure offshore platform around an existing caisson or drive pipe without any bolted, grouted, or underwater welded connections. This method involves the welding of a stop ring onto the caisson at a point just above the water line. A template having two sleeves for receiving piles and a sleeve for receiving a caisson is lowered over the caisson until the template rests on the stop ring. The template is concentrically aligned by a shim mounted to the top of the caisson sleeve. The caisson sleeve is centered around the caisson by inserting shims between the caisson and the caisson sleeve, and then the caisson sleeve is welded to the caisson and the stop ring. Piles are driven through the pile sleeves to grade using shims on the high point of the pile sleeve to align the pile with the axis of the sleeve as the pile sections are welded together. Once the piles are driven, the pile sleeves are centered around the piles by inserting shims between the piles and the piles sleeves. The pile sleeves are then welded to the piles. The deck of the structure is then installed using the template as the support.
