Alpha ARK is made of Kevlar & carbon fiber composites with a M-type trimaran boat shape which has strong resistance to impact. lts closed-cell foam filling and fully enclosed compartments are anti-sinking and waterproof design. The modular design is easily assemble and disassemble all parts for maintenance. Alpha ARK equip with different sensors to perform a variety of tasks according to demand and easily cope with a variety of complex operating conditions with multiple security protection mechanisms!
Great ability against wind and waves & excellent seaworthiness
Alpha ARK experience a trapezoidal-shaped trimaran with great seaworthiness and stable sailing ability. The high-speed air flow enters the channel from the horn and form an air cushion to generate additional lift that reduce the forward resistance to make it easy to accelerate when sailing.
Available Instrumentation
APPLICATIONS
Mapping of underwater topography and geomorphology
Tangxunhu Park is located in Wuhan Economic and Technological Development Zone, our measuring area is 207 meter long and 58 meter wide. The condition is complex due to a large number of collapsed branches and some protrusion reefs on the lake surface. We gather the data and send the relevant instructions from a safe area through shore-based software by taking underwater measurements with Alpha ARK unmanned ship. comparing with the traditional manual measurement method, it take the maximum Limited protection of personnel safety and improve operational mobility and efficiency.
Hidden pipe detection
Alpha ARK unmanned ship is equipped with side-scan sonar to imagine the underwater target. Combined with sonar image analysis and judgment,we help law enforcement find out the sewage pip and target polluters and provide strong data support to find out the water pollution source and the pollution area distribution.
ADCP section velocity measurement
Alpha ARK with the navigable ADCP can transmit data in real time and generate flow rate chart by mobile navigable vertical velocity, measurement of flow rate and section flow rate. It is more safe and efficient than manual measurement, at the same time, it avoid human errors and ensure the accuracy of data.
