... an amplification factor has been derived. For soft beds, high transverse vibrations were dampened by increasing the internal fluid velocity whereas they became amplified for hard beds. These results are of contemporary interest in the oil/gas industry where deep sea exploration is now receiving significant...

... Positioning (DP) systems has increased in the offshore oil and gas industry. As operations move into more hostile and deeper waters, the need for DP systems has become almost mandatory. There are different types of thrusters used in DP systems, but the majority are ducted; steerable over 360 deg...

...Dara Williams; Annette Harte; Frank Grealish The offshore oil and gas industry is predicting the discovery of more and more deep water reservoirs. Increased water depths create a requirement for reliable pipelines to economically recover these deep water fields and also to minimize flow assurance...
