A method of monitoring a diver's umbilical 14 comprises determining the position of at least one beacon 34 on the umbilical and calculating the path of the umbilical based on the position of the beacon. An alert is raised if the position of a clashing hazard (70, Fig 10), such as subsea equipment (20, 24, 26, Fig 10), is within a safety zone (30, Fig 10) that maintains safe clearance around the calculated umbilical path. The beacon may be positioned between the ends of the umbilical and may generate and emit an electromagnetic or acoustic locating signal into surrounding water. The safety zone may be defined with reference to the position of a hazard, in which case the alert can be raised if the calculated umbilical path departs from the safety zone. Alternatively, the safety zone can be defined around the calculated umbilical path, in which case the alert can be raised 1f a mobile hazard such as an ROV enters the safety zone. A diver umbilical with at least one beacon is also disclosed.
