5. Large-scale experiments conducted by the Navy which involve 

 the sinking of large vessels should be carefully instrumented so as 



to yield as much information as possible on the penetration phenomenon. 

 These should be supplemented by detailed tests of the surrounding 

 seafloor soils. 



6. Before the additional research is completed, the approach 

 presented in the SUGGESTED PREDICTION TECHNIQUE section should be used 

 for practical operations.
