Reduction of a Ship's Magnetic Field Signatures

In addition,active signature reduction technologies are described,such as degaussing and deamping,which attempt to cancel the fields surrounding a surface ship or submarine rather than eliminate its source.Table of Contents Introduction / Passive Magnetic Silencing Techniques / Active Signature Compensation / SummaryPredictive Maintenance by Electrical Signature Analysis to Considering this context,this chapter intends to disseminate important concepts to guide companies that have their own predictive group or want to hire consultants or specialized service to obtain good results through general predictive maintenance practices and,especially through electrical signature analysis.Predictive Maintenance by Electrical Signature Analysis to Considering this context,this chapter intends to disseminate important concepts to guide companies that have their own predictive group or want to hire consultants or specialized service to obtain good results through general predictive maintenance practices and,especially through electrical signature analysis.
