UXO detection survey along cable route
|Service||UXO detection survey along cable route|
|Water depth||Around 160m|
|Project duration||20 days (April 2019)|
|Industry||Submarine telecommunication cable|
The works consisted on a marine gradiometer investigation over 16 areas of interest along scattered along segments 5, 6.2 and 7 of the cable system.
The NAUTILUS is designed to the highest standards required for the offshore industry and ideally suited for a broad range of pre-engineering activities, construction support and IMR operations.
At 75 metres long, with a cruising speed of 10 knots and accommodation for 44 personnel, ACSM Nautilus is a robust, practical and efficient vessel for all inspection and survey requirements.
The Cable Maintenance ROV (CMROV) is a free swimming or tracked hydraulic ROV with 300kW/400HP providing an efficient and cost-effective solution for maintaining and installing regional and intercontinental submarine cable systems. This type of ROV has an extensive track record for operating globally in extreme environmental conditions and a variety of seabed soils.
CSM acquired gradiometer data, detecting magnetic anomalies along 50 m swath corridor using gradiometer frame of 4.5m and line spacing of 3.1m. This methodology ensured to obtain a 140% coverage overlap and to detect >19 kg pUXO exposed or to max buried depth 1m.
