USA: Sonardyne Equips Dragonquest with DP Inertial Navigation System

USA Sonardyne Equips Dragonquest with DP Inertial Navigation System

Sonardyne International has taken its first order for a Dynamic Positioning Inertial Navigation System (DP-INS). Vantage Drilling’s new 12,000 feet-rated drillship, Dragonquest, is set become the first deep water drilling unit in the world to be equipped with the new system when it begins operations in the Gulf of Mexico for Petrobras later this year.

Traditionally, an acoustic positioning system and two separate DGPS systems are used. However, a vulnerability remains should the acoustics be affected by aeration and noise and both GPS systems be simultaneously affected by signal disruption. The latter is particularly common around equatorial regions and during periods of high solar radiation. Solar activity is currently increasing and is forecasted by NASA to peak in 2013.

Consequently, there is a recognised need amongst operators for a third, independent DP reference that would allow safe rejection of a positioning error in one of the other two reference types.

DP-INS combines the complementary characteristics of Sonardyne’s Long and Ultra-Short BaseLine (LUSBL) positioning technology, with high integrity inertial measurements from its Lodestar AHRS/INS platform. The resulting output is resilient to short-term acoustic disruptions and completely independent from GPS.

A single navigation solution is computed and output to a display with intuitive status and quality metrics. Standard output telegrams are available for Converteam, L3 or Kongsberg DP systems.

In addition to the system’s deep water positioning performance and safety benefits, Sonardyne DP-INS delivers valuable costs savings. It can be used with fewer acoustic transponders deployed on the seabed, significantly reducing set-up time following a vessel’s arrival on location. The system also only needs occasional aiding from the acoustic system, extending transponder battery life and reducing maintenance operations.

Spencer Collins, Senior VP International Sales said, “We are delighted to be installing DP-INS onboard Dragonquest. The trials over the last year have successfully demonstrated to vessel owners and operators like Petrobras, that Sonardyne can now offer acoustically aided INS tailored for safe and efficient dynamic positioning operations.”

Substructures for UK Offshore Wind

Design, construction and installation

Optimising offshore substructures is one of the key challenges for reducing LCOE. Foundation designers have produced a variety of different solutions: monopiles, GBS, jackets, suction buckets and floating foundations. Looking at U.K. projects – different soils, water depths,fabrication timelines and installation challengescreate many questions for the industry to solve. We’re entering uncharted territory; projects arelarger, farther and more complex than ever completed.

Now is the time to have a close look at lessons learnt and define the room for improvement for the U.K. wind industry.
