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)

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...

Which Satellite Positioning Systems

The International Marine Contractors Association (IMCA, UK) has published new guidance on the selection of satellite positioning systems, warning that in recent years lower priority has been given to system selection than is wise. This is particularly the case when choosing a dynamic positioning (DP). The guide explains that the use of inappropriate systems has led to delays in project execution, vessel downtime and, in some circumstances, damage to assets. In the introduction to ‘Guidance on the Selection of Satellite Positioning Systems for Offshore Applications' (IMCA S 018) the association explains that the costs incurred during any of these incidents...
