Model approach:
the first communications path is primary. Residual outage probability
is reduced by each backup according to its entered availability and
independence. Communications availability is combined with modeled
ROC-site availability for an end-to-end estimate. Performance checks
compare each link with entered bandwidth and latency thresholds. The
resilience score combines continuity, link performance, failover, path
independence, ROC redundancy, monitoring, cybersecurity and vessel
fallback. It is a planning heuristic, not an IMO, IACS or class rating.
Planning and architecture screening only.
MASS remote-operation connectivity depends on the vessel concept of
operations, degree of autonomy, operational design domain, control
allocation, required human intervention, command and telemetry needs,
cybersecurity, satellite and terrestrial coverage, weather, antenna
geometry, spectrum, provider architecture, equipment redundancy,
shore-site design, emergency procedures and applicable class or flag
requirements. Availability percentages are user inputs, not guarantees.
Shared antennas, power supplies, modems, gateways, providers, cloud
services or shore infrastructure can create common-mode failures. This
tool does not establish MASS compliance or determine whether remote
operation is safe for a specific vessel.
