Seabed hazards such as unexploded ordnance (UXO), boulders, and debris can have major consequences for offshore wind installation, safety, project scheduling, and overall cost. UXO from wartime activities and post-war munition dumping is present in offshore energy development areas globally. In glaciated regions including Canada’s east coast, the northeastern United States, and northern Europe, boulders on and below the seabed create real engineering risks for cable installation, pile driving, suction bucket foundations, and installation vessel legs.
This webinar covers how Fugro’s integrated workflows and newly developed technologies are enabling more confident detection and mitigation of these hazards, from our five-phase UXO risk mitigation process through to an automated boulder mapping capability that uses machine learning to process side scan sonar data at a scale and speed that manual analysis cannot match.
Why UXO is a threat in offshore development areas globally, including the key challenges around schedule management, false positives, and detection methodology
How Fugro’s five-phase UXO risk mitigation process works, from historical desktop study and geophysical survey through to target identification, clearance operations, and ALARP certification
How boulders are distributed across glaciated offshore sites, why their variability in size, density, and burial depth creates engineering risk, and what that means for cables, foundations, and installation vessels
How Fugro’s automated boulder mapper uses machine learning on side scan sonar data to pick and dimension boulders at project scale, reducing weeks of manual work to days and improving site characterization accuracy
How integrating UXO and boulder hazard data earlier in the project life cycle supports better design decisions, smoother consenting, and reduced risk of costly encounters during construction
Many offshore energy developers know they need ALARP certification but are uncertain about what the process actually involves, how long it takes, and when to engage. This session gives you a clear, phase-by-phase picture of what is required, so you can plan ahead and avoid delays at the consenting and construction stages.
Manual boulder mapping at project scale is slow, expensive, and prone to inconsistency. Fugro’s automated boulder mapper processes the same data in a fraction of the time, with consistent accuracy across both seafloor and subsurface targets. If your project sits in glaciated waters, this session will show you what is now possible and what that means for your timeline and budget.
UXO encounters and unexpected boulder obstructions discovered during installation can halt operations, trigger costly redesigns, and create serious HSE exposure. This session makes the case, with real process detail, for why early hazard characterization is not a cost but a protection against far larger ones later in the project lifecycle.
