An AI sales agent's shore power crane order, checked before it goes out

An AI sales agent prepares an order for a shore power crane that connects ships at berth to the port grid. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the crane's electrical and mechanical rules and returns a verdict, every reason and the figures it computed.

Scope: Cavotec PowerReach and PowerReachNxG jib-crane shore power systems (LV, HV and RoRo/RoPax versions). See everything this validator covers

This validator models orders for the Cavotec PowerReach and PowerReachNxG shore power cranes, not just the scenarios shown below.

  • Electrical — the LV (up to 1.1 kV), HV (typically 6.6 or 11 kV) and RoRo/RoPax (11 kV, PC6 connector) versions, rated power (up to 1.2 MVA per cable LV and 9.5 MVA per cable HV, with up to 3 cables on PowerReach; 6.5 MVA RoRo/RoPax and up to 8 MVA PowerReachNxG, both given for one cable), and the PowerReach 15 kV rating that needs confirmation.
  • Mechanical — column heights of 4 to 16 m, arms of 2 to 10 m, the active cable length the datasheet tables give for columns of 4 to 12 m (PowerReach) and 4 to 10 m (NxG), compared with what the tide and vessel movement need (other column heights go to approval, and the 25 m PowerReach and 17.6 m NxG maximums are blocks), the 36 m/s structural wind rating (PowerReach), and the standard NxG column and arm sizes.
  • Quote — the rated power stated on the quote is compared with the computed rating and with the vessel demand.

Any PowerReach or PowerReachNxG order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (shore power is project-engineered and quoted per berth, so this validator produces no price build-up or line-item quote), options such as remote control, cages, vessel sensors and galvanizing, other Cavotec shore power products (PowerMove, PowerRun, PowerRange, PowerFeed, PowerFit, PowerReceive), and the mooring and cable reel product lines.

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
A crane version that does not match the voltage, plug or vessel typeOnly with care
Each version has its own voltage, plug and power rating; a product rule per version works but every new version adds a set of rules.		Version, voltage, plug and cables arrive in one request and are checked together.
Cable length that must follow the tideOnly with workarounds
Active cable length depends on the column height through a table, and must be compared with a berth requirement that sits on another line.		The cable length is computed from the column on every call and compared with the berth requirement.
Power that must cover the vesselOnly with care
Rating is a per-cable figure times the number of cables, compared with the vessel demand and with a stated figure.		Rated power is computed on every call and compared with the vessel demand and the stated figure.
Standard sizes versus sizes on requestOnly with care
Sizes outside the standard list need a person to confirm; a rule has to list the standard values and route the rest to approval.		Non-standard sizes come back as approval findings, separately from blocks.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or 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.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The PowerReachNxG datasheet covers the HV version only; the LV and RoRo/RoPax versions are PowerReach.
2The operating voltage on the quote is not offered for the selected version; LV is up to 1.1 kV, HV is typically 6.6 or 11 kV, and RoRo/RoPax is 11 kV.
3The RoRo/RoPax version uses the PC6 connector according to IEC 80005-1; the plug on the quote is not PC6.
4PowerReach accommodates up to 3 cables; the quote has 4.
5The column height on the quote is 3 m; PowerReach columns are 4 to 16 m.
6The column height on the quote is 17 m; PowerReach columns are 4 to 16 m.
7The arm length on the quote is 1 m; PowerReach arms are 2 to 10 m.
8The arm length on the quote is 11 m; PowerReach arms are 2 to 10 m.
9The berth needs 14 m of active cable length to follow the tide and vessel movement, but a column of 6 m gives only 9.6 m.
10The vessel needs 8,000 kVA, but the cables on the quote are rated for 6,500 kVA in total.
11The datasheet gives the rated power of this version with one cable; the order has 2 cables, so the power with more than one cable should be confirmed with Cavotec.

13The quote states a rated power of 10,000 kVA, but the cables on it are rated for 9,500 kVA.
14The quote states a rated power of 9,000 kVA, but the cables on it are rated for 9,500 kVA.
15Ratings above 12 kV are customized by Cavotec; the 15 kV rating should be confirmed with Cavotec engineering.
16The standard PowerReachNxG column heights are 4, 6, 8 and 10 m; the column of 7 m is available on request and should be confirmed with Cavotec.
17The standard PowerReachNxG arm lengths are 2, 5, 8 and 10 m; the arm of 6 m is available on request and should be confirmed with Cavotec.

24PowerReach is structurally rated for wind speeds up to 36 m/s; the site design wind speed is 45 m/s.
25The quote states a rated power of 1 kVA, but the cables on it are rated for 6,000 kVA.
26The datasheet lists the active cable length only for columns of 4, 6, 8, 10 and 12 m (up to 25 m, proportional to the column height); the length for a column of 14 m should be confirmed with Cavotec.
27The berth needs 26 m of active cable length, but the datasheet gives at most 25.0 m for this crane.
28The berth needs 18 m of active cable length to follow the tide and vessel movement, but a column of 10 m gives only 17.6 m.
29The vessel needs 8,500 kVA, but the cables on the quote are rated for 8,000 kVA in total.

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 shore power crane that connects ships at berth to the port grid. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the crane's electrical and mechanical rules and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a PowerReach HV shore power crane at 11 kV with the PC6 plug, 1 cable, a column of 6 m and an arm of 12 m. The quote states a rated power of 9,500 kVA. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The arm length on the quote is 12 m; PowerReach arms are 2 to 10 m. The berth needs 14 m of active cable length to follow the tide and vessel movement, but a column of 6 m gives only 9.6 m.
    6. 
      
  6. The validator returned two 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.
    7. 
      
  7. What this shows: for cable length that must follow the tide, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the column height to 10 m.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The arm length on the quote is 12 m; PowerReach arms are 2 to 10 m.
    12. 
      
  12. One finding cleared. Still blocking: arm length out of range.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the arm length to 10 m.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, 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.
    19.
