CASE STUDY MULTIBEAM ECHOSOUNDER integrated in SB 100 PRO USV for inspections & Bathymetry

Multibeam Echosounder WASSP S3R from FURUNO

The Company

Founded in May 2019 in Barcelona as a spin-off of the GPAINNOVA Group, GPASEABOTS’ activity revolves around the development of technologies for exploring and preserving the marine environment, such as USVs (Unmanned Surface Vehicles) and smart buoys. Just a few months after its creation, the company was granted the Fuera de Serie (“state-of-the-art”) Design & Innovation Award, promoted by one of the most important publishing groups in Spain, in the category of Sustainability.

In 2020, GPASEABOTS deployed more than 100 buoys to study the coastal waters on beaches in Eastern Spain and launched the SB 100 PRO model, a multipurpose marine drone for all kinds of tasks in sheltered waters. Depending on the payloads, this USV can be used in the fields of hydrology, water analysis, research, Search & Rescue (SAR), mooring inspection and other tasks. Likewise, its use allows access to restricted areas, in which navigation may be restricted, difficult or dangerous.

Another product developed by GPASEABOTS is SB 100 Cleaner, specially designed for sea water surface cleaning in ports and marinas.

The Opportunity

Naval robotics can replace tasks that have always been carried out by traditional methods, which have a high ecological impact and expensive operating costs. USVs are becoming widespread in several areas in the naval sector. In this real case study, we present a need that is shared by many ports: Mooring inspection in harbors and marinas.

Payloads

GPASEABOTS’ SB 100 PRO USV, the most versatile USV platform on the market for sheltered waters activities. It is an indispensable tool for a fast, efficient and precise work. Both the operating cost and its environmental footprint are extremely low, and it allows to expand the range of possibilities in the field of data acquisition.

CASE STUDY Using GPASEABOTS’ SB 100 PRO USV

The WASSP S3R Solution is a fully integrated kit which includes all the core components required for a Multibeam Survey operation, designed to ensure functionality, ease of use and cost effectiveness, all the while achieving accuracies required by international survey standards such as IHO S-44 Standard 1a and Special Order. INCLUDES: S3 including Processor DRX IP66, Transducer WBFT 90-190kHz, SBG Ellipse Dual RTK INS (Heading, position, pitch&roll, heave), Mini SVS Valeport, CDX, RPM & survey licenses.

Specific application: control and monitoring of dock constructions, multibeam bathymetry, draught control, dredging, volume calculation, inspection of structures and location of submerged artefacts.

Conclusions

The multipropose USV SB 100 PRO equipped with a WASSP S3r multibeam echosounder offers an unbeatable performance. A complete pack with all the necessary instruments to perform entire works while increasing potential applications in several marine sectors. It can to carry out control and monitoring of dock constructions, multibeam bathymetry, draught control, dredging, volume calculation, inspection of structures and location of submerged artefacts. INS SBG Ellipse Dual Antenna and SVS Valeport included on it ensure accuracy and quality of data.
