Exploring Vessel Drift Velocity & Collision Kinetic Energy in the 500m Zone

As offshore support vessels, SOVs, and construction vessels have grown in displacement, understanding how vessel mass, hydrodynamic added mass (surge vs. sway), and drift velocity interact is central to 500m zone risk awareness. We built this interactive reference to visualise open-water kinetic energy (E = ½·a·m·u²) across both Offshore Platforms/Substations (ISO 19902 / DNV-RP-C204) and Offshore Wind Turbine structures (DNV-ST-0126 / DNV-ST-0437).
