INS Sutlej successfully concluded the 18th joint hydrographic survey with Mauritius, covering approximately 35,000 square nautical miles in Mauritian waters. Conducted under the 2005 MoU on hydrographic cooperation, the mission significantly enhances marine charting, coastal regulation, and resource management, boosting Mauritius’s Blue Economy. Six Mauritian personnel received hands-on training aboard INS Sutlej in modern hydrographic techniques, strengthening local capacity. The ship also conducted joint EEZ surveillance and anti-piracy patrols with the Mauritius National Coast Guard, enhancing regional maritime security. The survey’s completion was marked by a ceremonial handover of the survey’s results to Mauritian officials on board INS Sutlej, attended by Mauritius Minister of Housing and Lands Shakeel Ahmed Yousuf Abdul Razack Mohamed and India’s High Commissioner Anurag Srivastava. This mission exemplifies the deep, enduring India-Mauritius maritime partnership and aligns with India’s MAHASAGAR vision, reinforcing India’s strategic influence in the Indian Ocean and commitment to safe navigation, sustainable ocean management, and regional cooperation. The survey was completed in late October 2025.
