Are you looking for a provider of pipeline and cable route surveys, both pre and post construction in Spain? Osiris Projects are a leading provider of pipeline and cable route surveys, both pre and post construction in Spain.
At Osiris Projects a large aspect of our work involves both inter-array and consented export cable route corridor surveys. Following desktop studies of existing available data, we undertake reconnaissance and detailed surveys comprising geophysical, acoustic, geotechnical and ground-truthing methods to assess site characteristics, potential hazards such as unexploded ordnance or wrecks, the location of existing cables and pipelines, and assist in the identification of sensitive benthic habitats. A clear understanding of the conditions the cable is likely to be subjected to allows the final route and burial depth to be selected with greater confidence that the integrity of the cable will remain in-tact. This level of detail assists in reducing uncertainty, or ‘de-risking’ the challenging installation phase.
Following installation, we conduct surveys to assess horizontal positioning, areas of exposure or movement and depth of burial. While undoubtedly interested in overall cable integrity, developers are particularly concerned with the depth of burial achieved. Forming part of their consenting conditions developers must often conform to a blanket depth of burial; commonly around 2m. Unless a detailed, independent survey is conducted the only information available to developers is that which is provided by their trenching and burial contractor.
Our newly procured Surgeon Tracked Inspection ROV is capable of performing such surveys. With a weight in air of 3 tonnes, the system can reach sea water depths of 100m and benefits from a full surveillance suite featuring 3 cameras, an obstacle avoidance sonar and a survey quality depth sensor as well as a various depth of burial profilers. The overriding benefit of the track-driven system is the ability to function within a wider environmental window in the challenging UK coastal environment, when compared with free-flying ROVs. This versatile platform can perform inspection operations in the surf zone and is capable of being loaded with an impressive array of subsea and monitoring tools. It can be operated from a variety of support platforms or may be operated from the beach.
The track-driven ROV is mobilised with a Teledyne TSS 350 for cable tracking, which utilises advanced pulse induction and digital signal processing technology to accurately determine ranges of buried cables. Resultant data is supplied to the support vessel via the ROV’s umbilical where all navigation and depth of burial data is logged by the survey computer. These results are logged and displayed in real time, with an option to be overlaid on the ROV video footage.
It has been suggested that the majority of difficulties encountered during the installation phase could be solved through adopting a collaborative approach. For Osiris Projects, we believe part of our success within offshore wind is derived from our experience serving the UK Oil and Gas industry working with clients such as Shell and BHP Billiton. We feel it is contractors such as ourselves who operate not only in a number of industries but also at different stages throughout the project who are well-positioned to apply firmly established principles in areas such as QHSE to support these newly flourishing sectors.
