Inspecting the inside of underwater hull
SPIE Proceedings, 2009In order to demonstrate the possibility of identifying the material within ship's underwater hull, sunken ships and other objects on the sea floor tests with the 14 MeV sealed tube neutron generator incorporated inside a small submarine submerged in the test basin filled with sea water have been performed. Results obtained for inspection of diesel fuel

High-resolution structured light D sensor for autonomous underwater inspection
OCEANS 2018 MTS/IEEE Charleston, 2018Sensors that can provide detailed 3D data underwater are a prerequisite for enabling autonomous inspection of e.g. seafloor integrity, ocean habitats and subsea installations with unmanned underwater vehicles.

An underwater robot for pipe inspection
Proceedings Fourth Annual Conference on Mechatronics and Machine Vision in Practice, 2002This paper describes the design of an autonomous mobile robot for use in the inspection of water-filled pipes. The design is based on ultrasonic communications, thus obviating the need for an umbilical cable. The control of the robot is distributed on a local area network which connects all the actuators and sensors. The robot has four legs, powered by

Autonomous inspection of underwater structures
Robotics and Autonomous Systems, 2015In the future our resource on land will be over exploited. The exploration of new resources in the ocean is in progress. Mining will be done on the bottom of the sea. The sea is also a big source of renewable energy. Off shore wind parks and tide plants are built. Also, the major world trade is handled over sea routes and several big harbors.

Robots to inspect welds underwater
Industrial Robot: An International Journal, 1994Examines research work to investigate the potential of using robot manipulators for underwater ultrasonic testing of welds in joints of complex geometry. Describes experiments carried out into non‐contact ultrasonic immersion testing using a six‐axis robot and an ultrasonic inspection system and gives results from scanning of a small T‐node specimen ...

Diving Reconnaissance and Underwater Inspection
Journal of the Waterway, Port, Coastal and Ocean Division, 1978Emphasis is placed on integrating the diving engineer into the coastal engineering design process to demonstrate how his special knowledge can become a key factor in designing and constructing underwater structures. The diving engineer has two basic functions: (1)Diving reconnaissance to obtain basic first-hand knowledge of a project site’s ...

Optimisation of Underwater Inspection Programmes
1991Underwater inspection of offshore oil and gas structures in the North Sea has evolved over the last 20 years. The initial techniques were fairly primitive by comparison with current methods.
