Abstract

um depressor em folha e fita é incorporado em um array sísmico rebocado para produzir uma sustentação descendente para seções do array ou componentes. os depressores em folha e fita podem ser dispostos nos cabos de escora a bombordo e estibordo ou nas cordas de separação externas. os depressores em folha e fita podem ser usados para submergir e operar o equipamento sísmico em profundidades tão pequenas quanto 60 m ou mais e são capazes de manter os cabos de superfície sísmicos rebocados nessas profundidades e ainda permanecer estáveis através de várias mudanças de velocidade e curvas.
