Abstract

La presente invencion se refiere a una estructura de plataforma no costera (10) para utilizar temporalmente una torre de perforacion autoelevadora (34), para operaciones de sondeo en aplicaciones de aguas profundas, que tiene una base (12) de artefacto flotante rígido, cimentado en el fondo, el cual soporta una torre de la superficie (28) la cual se extiende arriba de la superficie del océano (30) y una interconexion de soporte (110) de la torre de perforacion submarina, la cual está adaptada para soportar la torre de perforacion autoelevadora (34) para operaciones de sondeo. Al menos un tanque de emersion o caja de aire (112) para el soporte de la torre de perforacion flotante selectivamente, está conectado a la interconexion de soporte de la torre de perforacion, por lo cual una porcion de la carga temporal sobre la base del artefacto flotante rígido en la operacion de soporte de la torre de perforacion autoelevadora para operaciones de perforacion, puede ser aliviada o relevada.
