High Precision Positioning

Extension of the Condamine Port in Monaco
The port of Monaco is undergoing an extensive construction process that will help double the port's capacity and protect it from heavy eastern swells and dangerous Mediterranean storms. The new port will include two unusual pontoon-type breakwaters as well as an additional hectare of land reclaimed from the sea. The project, costing more than 243 million euro, was initiated in June 1999 and is today slightly ahead of schedule. The existing port was built at the beginning of the century. At that time the water was too deep to allow, using building techniques of the day, construction of a jetty... (read more)

Positioning First West African TLP

Fugro Survey BV is to undertake the crucial positioning work to install West Africa’s first Tension Leg Platform (TLP) on the Kizomba-A oilfield off Angola. The platform has to be positioned with an accuracy of less than a metre in water depths of 1180m. The contract was awarded to Fugro by Heerema Marine Contractors, which will install the TLP for the field operators. The TLP will be transported from Holland and installed at Kizomba using the float-over method to connect to pre-installed piles and tendons. When the TLP has been installed it will form part of the overall production scenario... (read more)

Dredge Efficiency and Precise Positioning

Integrating Dredging and Hydrographic Techniques
Dredgers involved in mining for (precious) minerals and metals often work in an inland dredging pit. Dredgers float in a ‘wet environment’ where the surrounding water is used as transport medium. The fact that the minerals are mostly covered in various sediments is one of the biggest problems in mining them. This article describes some of the techniques used in these dredging operations and illustrates the importance of integrating techniques and information. Most minerals, like rutile and zirconia, are to be found on top of a layer of clay with the highest concentrations found closest to it. Pewter is mostly... (read more)

Spectacular Positioning for MBARI Epedition

ROV tracking technology supplied by Sonardyne Inc. in Houston, USA to the Monterey Bay Aquarium Research Institute (MBARI) provided performance during an expedition to study recently discovered deep sea hydrothermal vents in the Gulf of California. Installed on MBARI’s Western Flyer research vessel, the Ranger 2 USBL system was used to track the position of the ROV Doc Ricketts as it dived down 12,500 feet (3,800 metres) to the seafloor and flew around the Pescadero Basin vent field, collecting video and samples for analysis. Despite the challenging conditions created by the vents spewing out super-heated seawater and suspended solids, the... (read more)

Centimetre-level Offshore Positioning Service

Fugro, headquartered in The Netherlands, has introduced a further advance in the field of GNSS augmentation with its high-accuracy G2+ service, designed to benefit offshore operators around the globe who require positioning and measurement accuracy at centimetre level. G2+ is an enhancement of Fugro’s G2 service (based on GPS and GLONASS) and utilises highly advanced GNSS augmentation algorithms developed in-house by its leading GNSS augmentation experts. The code and carrier-phase signals transmitted by GPS and GLONASS satellites are monitored globally by Fugro’s worldwide network of reference stations. These observations are processed centrally in real-time using the company’s proprietary algorithms to... (read more)
