DESCRIPTION OF EQUIPMENT 



Functional Description 



The CEL 20K anchor, whose design was detailed 

 in Reference 6, is comprised of two principal parts: 

 the fluke assembly and the gun assembly. Figure 4 

 shows the anchor in its cradle in the position 

 normally used for assembling the anchor. The basic 

 anchor stands about 7 feet high and weighs 1,800 to 

 2,000 pounds, depending upon which fluke is used. 

 Two fluke configurations were necessary to satisfy 

 the anticipated seafloor types; one for sediments and 

 one for rock and coral. Three sediment flukes are 

 currendy used to obtain peak performance in seafloor 

 soils. The physical dimensions of the four anchor 

 assemblies are detailed in Table 1. 



The anchor can be installed in a variety of ways 

 (see Appendix B, Installation and Recovery Methods); 

 however, the functioning of the anchor remains 

 basically the same (Figure 5). Above 50 feet the 

 anchor is prevented from activating by a switch and a 

 plunger that are both hydrostatically controlled. 

 Anchor embedment is initiated when a probe senses 

 the seafloor. The fluke assembly (fluke/piston) is 

 restrained by shear pin links until the gun barrel pres- 

 sure equals 3,000 psi. At this point, the fluke 

 assembly is propelled into the seafloor at velocities up 

 to 400 ft/sec while dragging the flaked downhaul 

 cable into the seafloor. The fluke can be set if 

 necessary, and the launch vehicle can be retrieved for 

 reuse or discarded, depending upon operational 

 requirements.
