Introduction

ME40 Autonomous Hydrology Measurement Boat is revolutionary force created by Oceanalpha in hydrologic investigation field, mainly applied to reservoir storage ,dredge monitoring ,bathymetry hydrology survey and tailing dam and pond survey, featured by its extreme shallow draft , available for exploration on offshore coast, shoals and reefs enlarging explorable area. ME40 is a platform of autopilot vessel controlled by auto and manual mode switches and a new concept of hydrographic survey integrated with RTK & single-beam sonar offering accurate information by inertial navigation system, generating visible data diagram, correct survey data in real-time, ensuring accuracy and efficiency.

ME40 Autonomous Hydrology Measurement Boat

ME40—Hydrology measurement boat adopting trimaran hull design to ensure stably sailing with function of intelligent obstacle avoidance to avoid collision is made of fiberglass composite with Kevlar & carbon fiber which is anti-corrosion, low temperature resistance leading to be adaptable to any extreme environment , which max. speed can reach 5m/s, duration can reach 4hours and bear 10kg payload with data transferring covered in 5km.

ME40 Autonomous Hydrology Measurement Boat

In April 2015 TC40 is used to measure the depth of Jiangxinzhou shallow water area in Yangtze River. The survey shallow area is 50m to the bank and 4km long, in which are full of crushed stones underwater. It is impossible for working ship to survey in this area. Autonomous boat with low draft is perfect to operate in shallow area.

ME40 Autonomous Hydrology Measurement Boat

Equipped with base station , Teledyne Odom single beam echo sounder , ME40-autonomous survey boat brings great convenience and high-effficiency
at the following points:

1. Labor-costreduction:survey work can be easily operated by two pefrsonswithout a group of workers.
2. Coverage:ME40 survey boat only with 25cm low draft ensure the survey in shallow water area which big working ship is not able to enter.
3. Accurate Survey Line: The survey line will be created by software automatically and high accuracy can be reached by smart control of autonomous boat under RTK GPS navigation.
4. Monitoring and data output: Video monitoring and ultrasonic obstacle avoidance make sure safe operation on water, survey data can be stored and processed in the software.

ME40 Autonomous survey in bathymetric application

Time: April, 2015

Location: Jiangxinzhou, Zhenjiang, Jiangsu

Company: Shanghai Waterway Engineering Design and Consulting Co.,Ltd.

Project Background:
The survey project needs to measure the depth of Jiangxinzhou shallow water area in Yangtze River. The survey shallow area is 50m to the bank and 4km long, in which are full of crushed stones underwater. It is impossible for working ship to survey in this area. Autonomous boat with low draft is perfect to operate in shallow area.

Equipment list:
1. ME40 autonomous survey boat
2. Base station
3. Teledyne Odom single beam echo sounder

Project benefit:
1. Labor-cost reduction. With ME40 autonomous survey boat, survey work can be easily operated by two persons without a group of workers.
2. Coverage. ME40 survey boat only with 25cm low draft ensure the survey in shallow water area which big working ship is not able to enter.
3. Accurate Survey Line. The survey line will be created by software automatically and high accuracy can be reached by smart control of autonomous boat under RTK GPS navigation.
4. Monitoring and data output. Video monitoring and ultrasonic obstacle avoidance make sure safe operation on water, survey data can be stored and processed in the software.

High accuracy survey lines and full coverage of shallow water brings great convenience and benefit to survey work. USV (Unmanned Surface Vehicle) as new efficient tool applied in hydrographic survey has been accepted by more and more survey operation.
