Ship systems
Cooling heat balance
Calculate both streams’ heat duties and distinguish energy balance from capacity.
Navigation and relative motion
CPA / TCPA
Explore two vessels’ relative motion, closest approach and prediction horizon.
Risk analysis
FMEA / RPN
Compare failure modes and RPN scores using explicit assessment criteria.
Risk analysis
Fault tree / FTA
Compare shared-support loss and a two-failure combination in a fixed fault tree.
Risk analysis
LOPA
Trace how an initiating event and protection layers affect an illustrative consequence frequency.

From flow to heat balance
Find the hydraulic operating point, then compare the heat carried by separate streams.
- Read the methodPump curves and system resistance
- Try the tools
- Reproduce the exampleTwo water streams: 83.6 kW and a changed outlet temperature
From failure modes to combinations
Explore failure modes, combinations and protection layers in turn; RPN, probability per demand and frequency answer different questions.
- Read the methodFMEA and FTA compared
- Try the tools
- Reproduce the exampleShared supply and two fans: the three-event startup example
From motion to prediction horizon
Establish the motion reference frame, then compare CPA with minimum separation inside the selected horizon.
- Read the methodHeading and motion through water and over ground
- Try the tools
- Reproduce the exampleOne encounter: 30-minute CPA and a five-minute horizon
