SUBPRO 1210 - Sub-Bottom Profiler

High Resolution at Good Penetration

Distributor-Seminar

Oceanology International 2008, London




High Resolution at Good Penetration

SUBPRO 1210 Sub Bottom Profiler

The SUBPRO 1210 breaks the limitations of

existing SBPs

SBP e.g. linear-, chirp-, parametric systems:

- high resolution means a low bottom penetration

- good bottom penetration means low resolution

- limitations at operation in shallow water

- low detection probability of embedded objects and

sediments

- different SBP tasks require different SBP systems




SUBPRO 1210 is…

• a high quality, universal system for wide range of sub bottom surveying tasks

• fulfils the requirements for most sub bottom surveying tasks in only one system

• developed for shallow to medium water depth• suitable for all sizes of survey-vessels or

ships as a portable or in-hull mounted system• a complete measuring system and easy to

integrate in complex survey systems • sufficient from survey to the scientific market

andfrom helmsman to experienced survey engineer

High Performance Controller PC

HQ 12 KHz Transducer




• High power Echosounder system up to 10 KW peak power

• High quality 12 KHz transducer• Advanced sending signal synthesis• High performance data acquisition• High dynamic range and SNR >160 dB• Advanced signal processing• GA Modular Application Framework

SUBPRO 1210 – Technological Basis




SUBPRO 1210 Application-Advantages

1.High resolution sub bottom measurements and simultaneously deepest bottom penetration in the seabed

2.High detection probability of (embedded-)objects and sediments

3.Reproducible measurings and results also at changings of environmental measuring conditions

4.Also optimised for very shallow water operations starting at 1.5 m




- Flexible system for universal survey tasks

- Highest Productivity for a fast result generation and

presentation

- Based on the same data set very different survey goals

are achievable

- Reduced surveying effort and survey time

- Due to the separation in two units, more flexibility for

installation on the bridge/operation room

- Higher protection of the investment, due to

echosounder independent upgrade possibility of the

controller PC

SUBPRO 1210 User-Advantages resulting in:




Applications of SUBPRO 1210

•High resolution subsoil exploration

•(Buried) pipeline and small object detection
