Environmentally friendly Flooded Member Detection via ROV - Completed
Goal
Flooded member detection is an inspection method which is utilized for analyses of offshore steel structures, where pipe sections are used. These structural elements (Members) are analysed for possible lack of water resistance which may indicate water leakage at the weldings, which are then selected for closer inspection. The method today is only undertaken by the use of ultrasound, if and when divers are used. This however requires a "living" A-scan in order to be useful and so a radioactive source is instead used when ROV (Remote Operated Vehicle) are used for inspection purposes. Through development of the inspection equipment it will be possible to also use ultrasound for ROV. This entails the improvement of safety and handling of ROV in comparison with the use of radioactive sources. The interest in such equipment which uses ultrasonic waves for ROV purposes is significant among many international underwater equipment operators. The result of the project will be presented to all interested parties at a seminar organized by Force and OCD.
Description
Participants: Force Technology and Offshore Center Danmark.
The development of equipment where Flooded Member Detection may be utilized with the aid of ultrasonic wave detection, in cases where one is operating with remote operated vehicles.
Mile Stones
The project was completed in 2004.
Results
The result of the project should guarantee the use of Flooded Member Detection with the aid of ultrasonic waves when using remote operated vehicles so that the probelms of safety and handling of radioactive sources is eliminated. A seminar will be held and organized by Force Technology and AUE, where the results of the project are presented for all interested parties.
