Crack Detection by the Field Signature Method. Status Report - Invitation to Participate: Development of a New Method for Monitoring Crack Formation in Offshore Structures

摘要

The proposed method for discovering cracks and monitoring their growth in offshore steel structures is based on measurements of the electrical field set up in the structure by an impressed electric current - a new version of the potential drop technique. Sufficient evidence is obtained - by the research already done - to state that the concept represents a promising method for structural monitoring of mobile rigs and jacket platforms.
