Underwater Inspection Risks

Journal of the Construction Division, 1981
A systematic approach for dealing with underwater inspection risks is examined. It consists of developing an underwater inspection program during the design stage and including the program in the p...

Inspecting the inside of underwater hull

SPIE Proceedings, 2009
In 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

Electromagnetic Inspection Underwater

1986
The examination of materials by electromagnetic methods is one of the most interesting aspects of scientific application. It is particularly appropriate to the application of such tests under water, as the magnetic effects are in no way diminished below the surface of seas or oceans.

UNDERWATER SHIP HULL INSPECTION

Naval Engineers Journal, 1980
ABSTRACTNavy managers need accurate information in order to make cost effective decisions. In the case of ship hull repair or maintenance decisions, the information can often be obtained through Nondestructive Examination (NDE) of the hull. Newly developed NDE hardware and techniques now permit many inspections to be performed on waterborne ships, thus

Underwater Inspection Of Naval Structures

Proceedings OCEANS '83, 1983
Nondestructive testing (NDT) performed underwater is one of the major maintenance methods to assure the efficient operation of naval structures such as piers, navigational aids, etc. Methods used for NDT of naval structures include general methods such as visual testing, ultrasonics and radiography.

Underwater inspection of offshore structures

Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1978
SynopsisUnder the Offshore Installations (Construction and Survey) Regulations 1974 all structures established or maintained in UK waters must possess a valid certificate of fitness. To obtain this certificate annual visual inspections of parts of the structure must be carried out both above and below water.

Underwater Inspection Using the AUV SeaCat

2012
Supported by the R&D-Project CView Atlas Elektronik together with further partners has recently developed an autonomous underwater vehicle (AUV) named SeaCat which is able to carry a multitude of payloads for various inspection tasks. A specific pan/tilt-inspection head has been created by the Bremen based institute DFKI Robotics Innovation Center ...
