The performance of modern information systems in the hydrosphere is based on the robustness of the wireless underwater communication between the cooperative subsystems. It is strongly intertwined with the coordination reliability for sharing resources and common purposes. Secure underwater coordination is a key functionality (C4I-STAR). The physical laws of the nature restrict the band-width and reliability of underwater communication links, the quality differs from deep to shallow water areas, with the hydro acoustical parameters, like the sound speed and sediment profile, with the weather conditions and day time. To over-come low data rates and non robust transmission links of submerged manned and unmanned platforms, error tolerant processes are needed to fulfill different hand-over maneuvers in the submerged teams. But, what are efficient process chains in this field? S-BPM has advantages to support users and scientists to handle this layer modeling for a standard network code of conduct.
