1 Inserts are 6 meters long; belting is in the form of a loop 

 (used double strength) with elongation characteristics under 

 load approximately equal to that of wire rope used.

(2) No-Damper Pipe Connection (MS-2) . In this module the mooring 

 bridle remained attached to the pipes but the mooring-force damper was 

 removed and replaced with a conveyor-belt loop of equal length. The 

 load elongation characteristics of the conveyor-belt loop are similar 

 to those of the wire rope used (hard line, hard connection) (Fig. 27). 



(3) No-Damper Tire Connection (MS-3). In this module the conveyor- 

 belt loop remained in place, but connection to the breakwater was made 

 by guiding the belt around two tires located on each pipe. In the 

 PT-1 module, tires numbered 9 and 10 were used for this purpose; in 

 the PT-2 module, tires numbered 15 and 16 were used (hard line, soft 

 connection) .
