Questionnaire respondents were asked to address situations in which ROV use would be more advantageous than the use of divers. Not surprisingly (given that the respondents are owner/operators of ROVs) the replies indicated a wide range of situations for the advantageous use of ROVs. However, the replies do reveal a prevailing set of opinions in this market sector.
About 80% of the participating ROV operators consider use of ROVs advantageous, even for some tasks that could be done by divers, because of the safety and economic advantages. Specifically, all of the operators in the inshore sector consider ROVs to be more advantageous, whereas among the offshore operators the percentage falls to 75 percent.
The tasks for which ROVs hold the advantage, in the operators’ opinion, are mostly inspections, followed by tasks connected to assembly of infrastructures and the recovery of objects. Respondents pointed out that ROVs gain an advantage in cases where the project is engineered to be carried out by remote intervention. You can find much more ROV Inspection tips online too.
Inspection in an area that is difficult to access (e.g. the inspection of the inside of a pipeline) is a task for which ROVs are preferred to divers by the respondents. In this type of inspection there is a high risk of being trapped in the inspection area, which could endanger the diver’s life, whereas the ROV can usually be dragged out by the umbilical (even if this damages the cable and the connection between the cable and vehicle, causing flooding of the electronic parts).
