Description

Maritime sector is facing a fast increasing in combining innovative aspects with marine operations especially for what regards cooperative operations and environmental monitoring and protection. In this scenario CNR-INM developed a large size innovative Unmanned Marine Vehicle (UMV) named U-SWATH (Unmanned Small-waterplane-area twin hull). The vehicle was studied for extending the unmanned marine operations both cooperating with a mother ship or with other unmanned vehicle like UAV (Unmanned Aerial Vehicle) and UUV (Unmanned Underwater Vehicle) also by providing launch, recovery and reload systems for these vehicles. Characterised by a modular structure, U-SWATH is expressly addressed to multi-purpose applications that include sampling and monitoring of environmental parameters in coastal, protected and dangerous waters,seabed mapping and monitoring, chemical-biological on-board analysis, first emergency monitoring for oil-spill, patrolling and civil protection, testing of new technologies and tools.

The use of high-tech like U-SWATH is nowadays considered a need for both ordinary and uncommon operations at sea. The envision for U-SWATH is to enhance precision in data collection and increase their spatial resolution with a reduction of the costs of the surveys.

For this reason a SWATH non-conventional design was chosen to ensure excellent seakeeping and good efficiency thus increasing the time and precision of the surveys. To increase the flexibility of U-SWATH each of the two submersible hulls is composed of modular and interchangeable elements that can be outfitted with different payloads, equipment, propulsive or manoeuvring elements. An innovative navigation and guidance control was studied in combination with a propulsion layout based on new azimuthal thrusters to increase the survey ability and the cooperation abilities.
