UXO Client Representative Services
Industry: Energy Infrastructure / Marine Site Investigation
Location: Southern Baltic Sea, Polish territorial waters
Year: 2025–2026
Project Overview
Sea Clouds acted as Client Representative for an offshore UXO survey and clearance campaign carried out for a large-scale energy infrastructure programme in the Polish sector of the Baltic Sea. Our team provided independent technical and QHSE supervision from October 2025 to May 2026, across two consecutive phases. Phase 1 covered the UXO geophysical survey campaign — data acquisition, processing and ALARP documentation — over a 450 ha nearshore and offshore area. Phase 2 covered diving inspection, identification and removal of the ferromagnetic targets selected during Phase 1. Working offshore in a 24/7 regime and onshore in an analytical role, Sea Clouds verified contractor compliance, data quality and safety performance on behalf of the Client.
