orcaflex-enrichment

Convert OrcaFlex .dat binary model files to enriched YAML fixtures using worldenergydata public databases (vessel fleet, riser components, pipe schedules). All stages run on licensed-win-1. Output committed to digitalmodel as test fixtures.

OrcaFlex Enrichment Skill

Converts binary OrcaFlex .dat model files to enriched, client-clean YAML test fixtures using worldenergydata public databases.

Pipeline (all on licensed-win-1)

Stage 1  Extract    .dat + OrcFxAPI → raw YAML params
Stage 2  Enrich     raw YAML + worldenergydata lookups → enriched YAML → client_projects/
Stage 3  Clean      enriched YAML → strip client names → legal scan → digitalmodel/

Stage 1 — Extract

cmd
python scripts\data\orcaflex\dat-to-yaml.py ^
    --input "\\dev-secondary\dde\Orcaflex\0000 Drilling Riser Development\Latest" ^
    --output "client_projects\data\raw\orcaflex-extracted\drilling-riser-development" ^
    --project drilling-riser-development

Extracts: general, environment, lines[], vessels[] per .dat file.

Stage 2 — Enrich + Stage (client_projects)

cmd
python scripts\data\orcaflex\enrich-and-clean.py ^
    --input  client_projects\data\raw\orcaflex-extracted\ ^
    --output digitalmodel\data\orcaflex\ ^
    --dry-run

Enrichment lookups performed

Object OrcaFlex field worldenergydata lookup Result field
Line OD (m→in) DrillingRiserLoader.filter_by_size(od_in) component_type, grade_range, api_standard
Line OD + WT PipelineSpecLookup.match_od_wt(od_m, wt_m) nps_in, schedule, grade_range
Vessel type hint from context BSEE rig fleet .bin vessel_class, water_depth_rating_m, dp_class

Enriched YAML output example (line object)

yaml
lines:
- component_type: marine_drilling_riser_joint
  nps_in: 21.0
  public_match:
    grade_range: [G105, S135]
    api_standard: API-STD-16F
    source: worldenergydata.vessel_fleet.DrillingRiserLoader
  dat_properties:      # numeric props from .dat — unchanged
    OD: [0.5334]
    WallThickness: [0.025]
    Length: [15.24, 15.24, 15.24]
    CDt: 0.01
    CDn: 1.0
  # name: stripped (client-specific)

Enriched YAML output example (vessel object)

yaml
vessels:
- vessel_class: drillship
  water_depth_rating_m: 3658
  dp_class: DP3
  public_source: worldenergydata.vessel_fleet.BSEE_rig_fleet
  dat_properties:
    InitialX: 0.0
    InitialY: 0.0
    InitialZ: 0.0
  # name: stripped

Stage 3 — Clean + Commit

cmd
bash scripts/legal/legal-sanity-scan.sh digitalmodel/data/orcaflex/
cd digitalmodel
git add data/orcaflex/
git commit -m "data(orcaflex): enriched fixtures from public vessel/riser databases"

worldenergydata Database Status

Dataset Status Location
drilling_riser_components.csv 24 rows (partial) data/modules/vessel_fleet/curated/
rig_fleet_full.bin 2,320 rigs (Feb 2026) data/modules/bsee/.local/rig_fleet/

Key worldenergydata API Calls

python
from worldenergydata.vessel_fleet import DrillingRiserLoader

loader = DrillingRiserLoader()
# Match riser joint by OD
joints = loader.filter_by_size(od_in=21.0)

# Get all riser joints
all_joints = loader.get_riser_joints()

# Get BOPs
bops = loader.get_bops()
python
# Pipeline spec lookup (after WRK-594)
from worldenergydata.bsee.pipeline import PipelineSpecLookup

lookup = PipelineSpecLookup()
spec = lookup.match_od_wt(od_m=0.2731, wt_m=0.012)
# → {nps_in: 10.75, schedule: "XS", grade_range: ["X60", "X65"], ...}

Blocked By

  • WRK-593: expand drilling_riser_components.csv + add construction_vessels.csv
  • WRK-594: create api_5l_pipe_schedule.csv + PipelineSpecLookup class
