Subsea node for docking underwater intervention drones

摘要

A subsea node 50 for connecting, e.g. by flying leads 51, an associated subsea system such as a well structure 100 to a host facility (1 Fig. 1) for provision of electrical power and data. The subsea node comprising, a termination 53 for connecting the subsea node to a cable 54 carrying power and data e.g. direct current and fiber optic (DC/FO) from the host facility. A platform, provided by a surface 56 of the subsea node is for landing an underwater intervention drone, and a subsea node inductive coupler 55 associated with the platform and connected to the termination for receiving power and data; whereby an underwater intervention drone landed on the platform and having a corresponding inductive coupler 61 can receive power and data via the subsea node inductive coupler 55. Allows for recharging of, and data provision for, a resident underwater intervention drone (UID).
