Italian Oil and Gas industry contractor, Saipem Società per azioni (S.p.A) [Saipem] has selected Tritech’s Gemini 620pd multibeam profiling system for its Work Class Remotely Operated Vehicles (WROVs).

Saipem has purchased a suite of Tritech products comprising Gemini 620pd sonars, Surface Control Units (SCUs) and Gemini Hubs, for accurate time stamped data. The Gemini 620pd sonars will run in a dual-head configuration, to provide a wide swathe of high-resolution bathymetry data. Operating at 620 kHz and a range resolution of 10mm alongside an update rate of up to 50 Hz, the Gemini 620pd is ideally suited for use on WROVs. Saipem is to deploy the system as part of their operations on the Shah Deniz Stage 2 (SD2) Project in Azerbaijan.

Saipem has also recently purchased additional Tritech products for use on their new Sonsub Innovator 2.0 WROVs. The products purchased for these new WROVs include the industry-standard SeaKing mechanical scanning profiling sonars, real-time Gemini 720i multibeam imaging sonars and SCUs.

Gemini 620pd is a high-resolution multibeam echosounder and with an angular resolution of 0.5 deg. Standard features include automated bottom tracking, variable gate setting and gate tilting as well as roll compensation.

Nick Hewlett, Senior Survey Coordinator and Survey Lead SD2, Saipem S.p.A, commented: “We buy from Tritech because they are a successful and experienced sonar manufacturer, producing reliable field-proven underwater sensors, backed up by world class support. Our initial investment of a suite of sensors and ancillary equipment furthered our commitment to investing in high-performance technology. The latest purchase of a Gemini 620pd dual-head profiling system will provide accuracy in our operations as we conduct cross-sectional profiling of pipelines and trenches.”

Angus Lugsdin, Business Development Manager, Tritech International Ltd commented: “We are delighted that Saipem has selected our Gemini 620pd multibeam profiling sonars for their important project and that they continue to adopt our latest technologies for their global operations.”
