... to a climber. It also gives the surveyor and/or structural expert the ability to study critical areas in these to them inaccessible areas "live" so that corrections and decisions can be made "on the spot", if required. It saves valuable time and removes the middle layer which rope access personnel/climbers...

... by surveyors. These inspections can be expensive, time consuming, and disruptive. This paper presents key challenges driving the need for UAV inspection, and benefits offered by this new technology. General acceptance criteria and requirements of UAV inspection (e.g., data acquisition), based on previous...

... and verification the project used selected special studies to check critical elements of designs and analyses. The marine activities on the project were scrutinized by Glo al Maritime, acting as marine advisors and warranty surveyors. The approach described in the paper enabled a small oil company to effectively...

... to enable accurate seabed Worldwide Ocean Surveying Limited (WOSL) is fitting such a sonar (a Simrad EM100- 12) in its research vessel "Ocean surveyor". The sonar swath produced is equivalent to twice the water depth, ie in 4000 meters a coverage of 8000 meters is obtained on the seabed, see Figure 1...

It is suggested that this sonar presents hydrographic surveyors with a capability not previously seen in civilian offshore operations. It is now possible for the surveyor to inspect rapidly 100% of the continental shelf seabed...

The first model involves hydroball/ hydrocouples installed by a lay barge, by the Arctic Surveyor, and by a vessel larger than the Arctic Surveyor. The eleven Ekofisk installations were made from lay barges...

... for this was not a lack of desire to progress by surveyors and civil engineers themselves, but it was because they were so limited by the instruments at their disposal. As the demands on the surveyor increased, it became evident that, very shortly, he would be unable to accomplish all that he was called upon to do...
