Veripos, a world leader for provision of GNSS positioning support to the offshore oil and gas industry, has been commissioned by Aberdeen-based Specialist Subsea Services (S3), the survey, positioning and ROV subsidiary of the Reef Subsea group of companies, to supply facilities and equipment aboard two of its new multi-purpose vessels, Reef Despina and Reef Larissa.
Under the long-term agreement, both 98.6m vessels, which have been chartered by S3‘s parent organisation, Reef Subsea, are designed for worldwide offshore construction support, inspection, maintenance and repair activities in deep waters and are being provided with Veripos’s Ultra Precise Point Positioning service. Enabling all GPS system errors to be removed or minimised by direct calculation, precise modelling or estimation, the service can realise continuous decimetre-level accuracies globally with a typical correction update rate of 30 seconds.
Veripos will also provide associated facilities for each of the Ulstein-designed vessels, including permanent installation of proprietary LD2-GGT2 integrated mobile units incorporating demodulators and multi-frequency receivers. They will be supported by purpose-designed Verify QC software for real-time position and quality control information, allowing any number of calculation permutations to be configured.
