Underwater Inspection Using ROV

Abu Dhabi International Petroleum Exhibition & Conference, 2021
Abstract ADNOC Drilling operates a growing fleet of 22 jack up units. These units require various inspections and tests to ensure that their integrity is maintained while conducting the drilling operations. One of these inspections is the underwater inspection which is required to be carried out twice every 5 years.

New Technology in Underwater Inspection

SPE Offshore Europe, 1981
Abstract The importance of a high standard of inspection and maintenance of offshore structures is evident from considerations of safety of personnel, prevention of loss of production due to shutdowns, or pollution of the sea due to oil discharges.

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

Kalypso AUV: A 3D-printed Underwater vehicle for inspection at Fisheries

Journal of Mechanisms and Robotics, 2023
In fish farms a major issue is the net cage wear, resulting in fish escapes and negative impact of fish quality, due to holes and biofouling of the nets.

Development of underwater inspection system for dam inspection

OCEANS 2015 - MTS/IEEE Washington, 2015
Deteriorations of social infrastructures have been progresses in Japan. To prevent accident due to its failing, effective inspection system is needed. We have been developing underwater inspection system for dam inspection which is called Dam Inspection System (DIS). It is composed by Unmanned Surface Vehicle (USV), and Remotely Operated Vehicle (ROV).

Underwater ROV Software for Fish Cage Inspection

2021 44th International Convention on Information, Communication and Electronic Technology (MIPRO), 2021
This paper deals with the development of control software for a remotely operated vehicle (ROV) as part of an automated fish cage inspection system in aquaculture. The ROV navigates autonomously around the fish cages streaming video to the topside computer that runs the algorithms for vertical rope detection.
