Offshore ROV/AUV Survey Productivity, Weather Window & Spread Cost Tool
Offshore ROV/AUV Survey Productivity, Weather Window & Spread Cost Tool
Plan subsea survey acquisition, account for overlapping survey lines, vehicle endurance, mobilization and weather windows, and model how lost workable hours affect schedule and spread cost. Compare deployment strategies without confusing estimated coverage with accepted survey deliverables.
Survey Work Packages & Deliverables
Enter area (km²), linear track (km) or point inspections (count). For area missions, effective track-kilometres = area ÷ (swath km × (1 − overlap)). Point surveys use hours per target instead. Durations include rework and sortie turnaround allowance.

ROV/AUV Vehicle & Launch System Register
Counts represent available survey vehicles. Vehicle availability reduces modeled usable hours. LARS capacity and shared vessel lanes cap parallel activity; equipment availability is not an approved weather limit.

Weather Window & Access Outlook
These are user-entered daily scenario windows, not live metocean data. Each day's available hours are reduced by the operational thresholds. No workable hours outside the entered forecast horizon are assumed.

Critical Readiness & Survey Evidence
Critical items not verified create a planning hold irrespective of throughput or forecast cost. Attachments and certification status must be verified outside this component.
