Abstract: In a first aspect, a Torpedo-type Support-Pile Module (SPM) is disclosed, which includes a panel for wet connection, a burial restrictor device, and a base jointly mounted to a Seismic Sensor Module (SSM), which houses a combination of a pressure sensor with particle velocity or particle acceleration sensors, in addition to inclination sensors. In a second aspect, a telescopic-type SPM is disclosed, which includes a panel for wet connection, a base jointly mounted to a SSM, and at least two cylindrical sections capable of being inserted into each other, thereby reducing the storage and transport volume of the SPM. The panel of any one of the SPMs is connected to a wet connector of a Subsea Seismic Data Acquisition Module (SSDAM), the SSDAM in turn providing power to the seismic sensors of the SSM during the seismic data capture. At the end of the capture, the seismic sensors send the acquired data to a memory located in the SSDAM, and the connection between the panel and the connector is finally disconnected. Also disclosed are seismic data acquisition methods and a seismic survey system, for the purposes of permanent marine seismic monitoring related to SPMs. Advantageously, this methodology has the possibility of applying part of the logistics described above in reverse, so that, at the end of the seismic data acquisition campaigns or even when convenient, the telescopic-type SPMs can be removed, freeing the seabed of such items and leaving the same as it was before installation.
