Cold spray metal embedment is an innovative antifouling (AF) technology that delivers metal
particles with AF properties into many thermoplastic polymers. AF efficacy was quantified for …

Axisymmetric turbulent boundary layers that develop around streamwise oriented long
cylinder-like objects can be found in many applications, such as towed array sonars or …

Marine seismic is a well established method to search for subsurface hydrocarbon deposits.
However, the method is often limited by various sources of noise, of which flow and swell …

Design and development of lightweight arrays has been a subject of intense study in recent
years. This is largely owing to the successful deployment of autonomous vehicles as …

This work investigates how a highly (super) hydrophobic surface can be used to reduce
turbulence-generated drag and noise on a towed streamer cable. The work is done by …

Traditional marine seismic acquisition methods (streamer, OBC) have reached some
inherent limitations that are difficult to overcome. Some new methods such as nodes have …

The limitations of the conventional streamer acquisition technique are first presented and
then the new offshore acquisition method named Midwater Stationary Cable is explained. By …

The world economy is demanding an increasing volume of oil and according to oil market
specialists this trend is not expected to decrease in the next decades. The easy oil is gone …

For marine seismic surveying, it is commonly assumed that the noise level decreases with
depth. In addition, recent advances in broadband seismic have shown that a greater …

Ten years ago, Kietta launched a project to develop a new method of marine seismic
acquisition using midwater stationary cables and autonomous surface vehicles. We present …
