Dual-SATCOM Availability, Common-Mode Outage, Failover, Added Connectivity Value, Fleet Cost & Payback

Ship Satellite Network Addition ROI, Redundancy & Connectivity Value Tool

Screen whether adding a second shipboard satellite network is worth the cost. Estimate how many primary-network outage hours the second path can actually remove after common-mode outages and failover success are considered, then value the avoided downtime plus crew, commercial and operational connectivity gains. Advanced mode adds route coverage, failover events, bandwidth, fleet scaling, lifecycle hardware cost, use-case value rows and cyber/network readiness.

Fast Redundancy & ROI Screen

Availability values should reflect the ship's actual service and route where possible. Common-mode outage is the estimated share of primary outages that the secondary path would also suffer because of shared weather, onboard power/network faults, common provider/backhaul dependencies or overlapping coverage gaps.

Network & Cyber Resilience Readiness

Connectivity planning screen only: this tool does not establish an SLA, guarantee route coverage, certify automatic failover, verify satellite-provider independence, establish GMDSS / distress-and-safety compliance, certify cyber resilience or replace a shipboard network design. Availability and common-mode assumptions must be derived from the actual primary and proposed secondary services, vessel route, onboard architecture and operating history.
Resilience context: IMO MSC-FAL.1/Circ.3/Rev.3 calls for risk-based maritime cyber management that identifies digital-system dependencies, network connections and systems critical to ship operations, and includes business-continuity, backup and recovery considerations. IACS UR E26 and E27 provide additional cyber-resilience context for ships and onboard systems, particularly for applicable newbuilds. A second satellite service can improve communications resilience only when common onboard, power, provider, coverage and cyber failure modes are controlled.
