The requirements for the Ocean Engineering Range at SCI have ex- 

 panded over the years and even greater development is seen for the future. 

 The Range is limited by the state-of-the-art in operations instrumentation 

 and total areas instrumented. The following are specific requirements 

 that must be implemented in the near future: 



1. Deep instrumented areas, to depths to 20,000 ft 



2. Detailed bottom surveys at all depths from 100 ft to 1,000 ftand 

 at the 5,000 ft and 12,000 ft depths for sea floor operations 



3. Surface support platforms with good stabilization and position 

 keeping capabilities for long-term deep sea operations 



4. All weather surface handling for submersible vehicles 



5. Precise underwater navigation systems to locate accurately 

 bottom and in-volume instrumentation sites 



6. High resolution underwater imaging systems to monitor tests 



7. Additional shore support for sea operations 



8. A mobile instrumented saturation diving R&D test facility 



9. Additional man-rated pressure /temperature tanks for physio- 

 logical and diver's equipment testing 



10. Additional and larger equipment pressure/temperature cycling 

 test tanks 



To keep pace with the demands of the burgeoning field of ocean 

 technology, a development program planned for the next 10 to 15 

 years covers a number of items. There is a need for a protected 

 harbor and docking facility where technical and support craft can safely 

 berth diaring inclement weather. This project includes a protective 

 breakwater, wharf, and small craft piers. Close to the causeway- 

 supporting preparation, maintenance, and repair of systems being tested 

 will be constructed. In order to give proper support to the divers on the 

 Range whose diving depths must at times exceed the limitations for nat- 

 ural air breathing, a mixed gas recompression chamber and equipment 

 preparation facility must be made available. A concept to fulfill other 

 future requirements is an imderwater marine railway. This test facility
