Cable and Cable Dynamics Analysis of CSSSRNM (Combined Surface Ship and Submarine Radiated Noise Measurement) Array Installation, Nanakuli, Hawaii

摘要

The statement of work for this project lists three primary tasks. The first task is to determine and confirm the mechanical parameters of the specified cable and and armor package. The maximum tension loading and bend diameters that the cable will withstand without failure is also to be calculated. The task shall also recommend and confirm safe working loads for cable handling. The second task in the statement of work is to simulate the cable laying operation. A dynamic cable analysis program such as SEADYN, is to be used in the time-domain to determine the maximum loads expected on the cable during installation. The two primary points of interest in this analysis consist of (1) the loading on the Sea Cable as it supports the double armored Shore Cable in the water column, and (2) the installation procedures and configurations to prevent undue loading on the cable during the entire operation. The third task consists of recommending the maximum tension and ship velocity as a function of time, while laying the cable over the escarpment and on the downslope portion of the cable laying operation.
