Summary
A saturation diver’s umbilical became trapped between pipelines when a newly laid line shifted during flooding, interrupting breathing gas. Another diver supplied pneumo gas and helped free the umbilical. The flash examines pipeline configuration, tidal current and umbilical routing, emphasising assessment of existing conditions and management of changing variables.
