Indonesian Positioning Contract

Veripos has been awarded a two-year contract by hydrographic survey and subsea specialists PT Pageo Indonesia of Jakarta for provision of high-precision Differential GPS positioning services in support of major site survey and rig-positioning operations being carried out in the Mahakam Delta, Kalimantan on behalf of Total E&P Indonesie, a subsidiary of the Total Group of companies.   The services, which include supply of Veripos' latest LD3 integrated mobile GPS receiver and demodulators for calculating positions and output of data, are being used in support of jackup, semi-submersible and swamp drilling barge operations as well as shallow water survey vessels...

Deepwater Positioning Buoys Shipment

Falmouth Scientific has shipped 30 deepwater positioning buoys worth almost half-a-million US dollars to the Integrated Ocean Drilling Program (IODP). These beacons will be employed by IODP's drilling vessel for deepwater (6000-meter) positioning. FSI's instruments will be used to accurately position IODP's drilling ships in order to extract cores of the Earth's crust at the bottom of the ocean.   The mission of the IODP is to explore Earth's history and structure recorded in seafloor sediments and rocks, and to monitor sub-seafloor environments. Their efforts are part of a global team from the US, Japan, China, Korea and Europe.  ... (read more)

Deepsea Positioning Accuracy

First NEMO Tower for Astrophysical Research
The Italian Istituto Nazionale di Fisica Nucleare (INFN) is developing a large underwater apparatus to investigate new frontiers in astrophysical research. The NEutrino Mediterranean Observatory, NEMO, consists of a 3D-array of optical sensors capable of detecting the primary source of extremely high-energy neutrinos. This article covers underwater positioning techniques: system architecture, technical, advanced and data processing aspects, and preliminary data analysis. The first prototype, NEMO Phase 1, was deployed in December 2006 off the coast of Catania. A set of synchronous acoustic beacons was installed in the sea at a depth of 2,000m to position a large number of optical... (read more)

Guidelines for GNSS ­Positioning

A joint OGP & IMCA Revision of the 1994 UKOOA Guidelines
The original UKOOA Guidelines for the use of differential GPS in offshore surveying, published in 1994, were widely used within the offshore survey industry. In 2005, the International Oil & Gas Producers Association (OGP) took over the custodianship of the guidelines from Oil & Gas UK (formerly UKOOA). At that time it was recognised that the original guidelines needed updating in order to reflect the rapid technical advances in satellite navigation technology of recent years and to maintain the purpose and relevance of the original guidelines. OGP and the International Marine Contractors Association (IMCA) agreed to work together on the... (read more)

Positioning Contract for Veripos

Allseas, UK, has awarded Veripos (UK) a further three-year contract for continuing provision of specialist GNSS positioning services for its entire fleet of vessels headed by the world's largest pipelaying vessel, the 300m Solitaire. Other vessels concerned include companion DP pipelayers Audacia and Lorelay in addition to the DP trenching support and subsea installation vessel, Calamity Jane, the anchored pipelay barge, Tog Mor, and the ROSVs Highland Fortress, Highland Navigator and Highland Rover. Allseas expect to add to its fleet during the course of the contract what will be the world’s largest construction support vessel, the platform installation-decommissioning and pipelayer, Pieter Schelte, presently under construction at Daewoo Shipbuilding & Marine Engineering in...

Geolab Positioning Contract

Veripos has been awarded a further three-year contract by Naples-based GeoLab Srl, one of Europe's leading turnkey offshore survey and construction support organisations, for provision of high-precision GNSS positioning services. The contract extends the relationship between the two companies following an earlier three-year agreement.   Under the new agreement, Veripos will continue to provide GeoLab with a full range of proprietary globalised satellite positioning facilities extending from its Standard GNSS augmentation service to its latest Ultra Precise Point Positioning (PPP) capability which ensures decimetre-level accuracies by minimising or removing all main GPS error sources.   Together with the supply of...

Community-sourced Positioning Project

The TeamSurv consortium offers sailors and powered boaters the opportunity to join a community that collects and shares depth information recorded by vessels' existing depth sounder equipment. Depth data, along with the vessel's position, are automatically logged and stored in real time, either by a software utility running on a Windows PC or using a dedicated hardware logging device. At the end of the voyage, the logged data is uploaded to the TeamSurv website. Submitted data are combined and processed, using unique algorithms, by TeamSurv and are corrected for actual or predicted water levels and other factors so as to... (read more)

Dynamic Positioning Conference Programme

The Dynamic Positioning Committee of the Marine Technology Society has issued an Advance Programme for the 2010 Dynamic Positioning Conference. The Annual Conference will be held at the Westchase Hilton, Houston 12th and 13th October 2010. The Conference traditionally places a strong emphasis on new technology and this year is no exception with sessions on DP in The Arctic and New Applications, as well as a full session on Quality Assurance. As in the past, there will also be sessions on Design, Sensors, Thrusters and Operations. Expanded exhibit space will allow a larger number of vendors to display their products... (read more)

LBL Underwater Positioning

Long baseline (LBL) positioning has many applications both commercially and in research, from surveying a ship hull to positioning offshore platforms in deeper waters. The technique consistently provides accuracies in the order of decimetres over large areas, independent of depth. Recent advances include the integration with other acoustic techniques or with inertial navigation systems for greater levels of accuracy. Since navigation by GPS isbased on electromagnetic signals that cannot penetrate water, subsea positioning requires a different approach. As sounds waves travel through the sea they alternately compress and decompress the water molecules; these compressions/decompressions are detected as changes in pressure.... (read more)
