Problem Statement: Maritime Autonomous Surface Ship

Design a production maritime autonomous surface ship (MASS) platform (Rolls-Royce/Sea Machines-class): closed-loop perception, COLREGS-aware planning, propulsion control, fleet operations, and flag-state-grade logging. This section covers problem statement: maritime autonomous surface ship in the understanding phase.

Operational detail

Quantify CPA violations/day, VoyageTrace lag, and VSAT utilization before naming SKUs. State deterministic VoyageTrace replay for any safety-critical rudder decision and AP navigation telemetry / CP voyage state with explicit failure stories (radar loss, ENC skew, VSAT outage).

Failure and edge cases

AIS spoof near port entrance.

Why interviewers care

Autonomous Ship System interviews reward crisp scope, explicit trade-offs, and failure stories—not generic microservice diagrams.

Interview checkpoint

Name one failure story for Problem Statement: Maritime Autonomous Surface Ship that proves you understand real outages, not happy-path diagrams.

Key Highlights

•sense-navigate-act loop with safety envelope
•ODD: sea state, traffic density, channel class
•shore operations center (SOC) oversight
•IMO incident replay and voyage evidence
