The instruments required to monitor anchor performance would require 

 careful conceptual and preliminary design before fabrication is initi- 

 ated. The U-joint and mooring line would be contracted to experienced 

 manufacturers . 



Transport and Install Anchor . After the anchor is fit with its 

 instrumentation and, possibly, the U-joint auU mooring line installed, 

 the anchor would either be floated out using attached buoyancy tanks or 

 it would be loaded onto a launching barge for sea transport. If trans- 

 ported in a self-floating mode the anchor would be supported by several 

 integral or attached air-filled buoyancy tanks. All facets of the 

 anchor installation and mooring line deployment would be carried out to 

 complete the demonstration. The attached instrumentation should monitor 

 the anchor behavior during free-fall descent and during landing on the 

 seafloor. Arrangements should be made for visual inspection of anchor 

 attitude and condition shortly after the landing. 



Test Anchor. Full testing of the mooring system will require two 

 efforts: (1) a long-term serviceability test of the mooring system, and 

 (2) a short-term proof loading of critical mooring system components. 



The purpose of the long-term serviceability test is to demonstrate 

 the durability of the mooring system components (especially the mooring 

 line, U-joints, and swivels) in a near-prototype-size installation and 

 to verify the station-keeping performance of the mooring system in 

 response to those wind, current, and wave forces that do occur during 

 the 1-yr minimum test period. This mooring system test is expected to 

 be a part of the 5-MWe OTEC pilot power plant installation. In the 

 event such a combined mooring and 5-MWe platform test is not advisable 

 due to other OTEC program constraints, then the mooring system could be 

 tested under the load of some other suitable surface platform acting as 

 a duony load. 



Unfortunately, this long-term load test - with the 5-MWe pilot 

 plant or a dummy surface platform - will not verify the ultimate load 

 capacity and probably will not demonstrate whether the mooring system 

 can resist the design load, because the design storm required to supply
