Abstract
A method for operating a marine seismic survey system includes deploying from a seismic vessel at least two lead-in cables each functionally coupled at one end thereof proximate a respective paravane. The lead-in cables have at least one spreader cable functionally coupled between the paravanes. Strain is measured at least one position along each lead in cable; and a length of each cable is adjusted such that the measured strains are substantially equal.
