Subsea Construction

Century Subsea has taken delivery of a first, with an option for a second, Kongsberg Maritime Subsea HAIN, (Hydroacoustic Aided Inertial Navigation) for a 90-day project in the Gulf of Mexico for a major oil company. Subsea HAIN, developed from the HUGIN AUV navigation system, has now been used in several deepwater projects to enable increased accuracy of underwater positioning with minimal sub-sea hardware, thus significantly reducing sub-sea construction costs. Century Subsea has also purchased a new-generation HiPAP 350P (Portable) USBL System. The HiPAP 350P has the pitch-and-roll sensor mounted in the transducer head, providing the optimal solution for minimising... (read more)

Marine Construction Receivers

Trimble has introduced two new Global Positioning System (GPS) receivers designed specifically for marine construction applications: the Trimble SPS361 and Trimble SPS461 GPS Heading Receivers. These dedicated marine receivers deliver both precise GPS heading together with Differential GPS (DGPS) or Real Time Kinematic (RTK) positioning.   The receivers are developed for a range of applications when used with Trimble HYDROpro marine software, including: the precise placement of structures such as piles, bridges, caissons, marinas, and coastal defenses; dredge head positioning; vessel positioning and tracking; and offshore rig positioning with anchor handling.   The Trimble SPS361 is an entry-level DGPS Heading...

Construction for Sheringham Wind Farm

Construction work on the Sheringham Shoal Offshore Wind Farm site started last week with the arrival of the 164m Nordnes vessel, which will position rocks at selected foundation locations in preparation for the start of the installation of the giant monopile structures next month. Using a precision technique, she will place 2-9" filter rocks in a ‘donut' shape around the site of 77 of the 90 foundation locations to reduce the likelihood of scour and protect the cables when they are installed. Scour protection is needed for wind turbine foundations, as well as other types of marine structures, due to... (read more)
