ABSTRACT:
A substantially underwater system comprises a plurality of retrievable substantially autonomous subsea modules (12, 13, 17, 18) and switchgear (15, 16, 21a . . . h). A host facility (6) and the modules are connected in series so as to form a circuit, the host facility providing power to all of the modules. Operation of the switchgear electrically isolates a module or a plurality of serially adjacent modules so that the module or modules can be removed without cutting off the power supply to any of the remaining modules of the system. Module based parts of the switchgear (21a . . . h) only or a combination of module based parts (21a . . . h) and host facility based parts (15, 16) of the switchgear are actuated depending on which module or modules are isolated and removed.
