Predictika · Marine stabilizer, thruster and steering orders

An AI sales agent's marine systems order, checked before it goes out

An AI sales agent prepares an order for a vessel with stabilizer fins, tunnel thrusters and a steering system. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the fin and thruster ranges and the order rules, and returns a verdict and every reason.

Scope: Marine stabilizer, thruster and steering orders: retractable (SR), fixed (SF) and zero-speed (SFZ) fins, HMC and HMF tunnel thrusters, closure doors, hydraulic steering, rudder roll and shock resistance. See everything this validator covers

This validator models marine stabilization, thruster and steering orders, not just the scenarios shown below.

  • Stabilizer fins — the retractable SR-1 to SR-5, fixed SF-0 to SF-4 and zero-speed SFZ-0 to SFZ-3 series, their fin area ranges, the electric power the vessel must supply, the vessel length bands of the zero-speed fins and the options that belong to one series only.
  • Thrusters and steering — the HMC-0 to HMC-3 controllable-pitch and HMF-10, 12 and 14 fixed-pitch tunnel thrusters with their propeller diameters and shaft power ranges, closure doors, hydraulic servo and cylinder steering, and the rudder roll system.
  • Naval options, totals and reviews — shock resistance and rudder roll on naval vessels, the total fin area and thruster power stated on the order, and the reviews that carrier-class vessels, shock-resistant steering and 5,000 kW or more of thruster power need.

Any marine stabilizer, thruster or steering order that touches these rules is in scope — not only the scenarios pictured here. Not covered: propulsion lines, azimuth thrusters, engines, ship construction and offshore products. Series names and size ranges follow Fincantieri's public product page; the electric supply of the zero-speed fins, the compatibility rules, vessel classes, thruster counts and review thresholds are modeled, not published by Fincantieri. No prices are modeled.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Fin area ranges and the electric power each fin model needsOnly with care
Each fin model needs its own area range and power rule, and the vessel supply has to be compared with the model chosen.		The model, fin area and available power are fields of one request, checked together on every call.
Zero-speed fins by vessel length band and vessel typeOnly with care
The length band and the yacht-only condition need a separate rule for each of the four SFZ models.		The model, vessel class and length are checked together against the band of that model on every call.
Options that belong to one fin seriesOnly with care
Flap, opening direction and zero-speed function each need a rule that looks back at the fin series chosen.		The options and the fin series are in one request, so a mismatch is found whatever order they were chosen in.
Thruster diameter, shaft power and count per modelOnly with workarounds
Every thruster model has its own diameter and power range, plus a count limit and a total to reconcile with the stated figure.		The thruster model, size, power, count and stated total are checked together on every call.
Reviews for naval options, carrier class and very large thruster powerOnly with workarounds
The review thresholds depend on the vessel class and on a computed total, so they have to be recalculated whenever the order changes.		Class, options and the computed total thruster power are checked together, and every review comes back with the blocks.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a vessel with stabilizer fins, tunnel thrusters and a steering system. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the fin and thruster ranges and the order rules, and returns a verdict and every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an order for a corvette, on a vessel that supplies 200 kW of electric power: SR-5 stabilizer fins of 20.0 square meters each. The order states a total fin area of 30.0 square meters and total thruster power of 1400 kW. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The SR5 stabilizers need up to 220 kW of electric power and the vessel supplies 200 kW. The zero-speed function comes with the SFZ fin series; the order has SR5. The HMC1 propeller diameter of 1,400 mm is outside the 1,450 to 1,700 mm range of that model. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other and against the stated total.
    7. 
      
  7. What this shows: for fin area ranges and the electric power each fin model needs, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the stabilizer fins to SR-3, the fin area per fin to 12.0, the propeller diameter to 1,500 mm, the steering torque to 800 kNm and the stated total fin area to 24.0. It removes the zero-speed function.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
