Tests of the resistance of these stanchions to various 

 forces have been initiated and some results are available. 

 The base sections used in the array have been subjected to 

 preliminary tests adjacent to the NEL pier. A base pipe 

 was jetted into the bottom and a pipe cap with a welded eye 

 was screwed onto the threaded end so that a cable could be 

 attached. A cable was run from this eye through a pulley 

 fastened to a pier piling and up to a walking crane on the 

 pier. Various degrees of upward pull on this cable were 

 measured by a dynamometer placed between the cable and 

 the hook on the crane. Simultaneously, the angular displace- 

 ment of the pipe was measured by a diver (fig. 8).
