Cargo Throughput, Hydraulic Duty, Drive Power, Discharge Time, Energy, Fuel-Equivalent Consumption & Berth Exposure
Tanker Cargo Pumping Time, Power & Fuel Cost Tool
Estimate tanker cargo-discharge time, pump demand, energy use and fuel-equivalent operating cost. Advanced mode models the discharge stage by stage and constrains actual flow by the lowest of requested pump throughput, available drive power and an optional terminal or system rate cap.

Sequential Discharge Stages
Use different stages for high-rate discharge, reduced-rate tank groups, high-backpressure sections or final bulk discharge. A terminal/system flow cap of 0 disables that cap. A rated drive power of 0 disables power-limit checking for that row.

Cargo-Pumping Readiness
Planning / energy model only: this tool does not establish a safe cargo-pump operating point, maximum manifold pressure, NPSH margin, surge limit, inert-gas requirement, stripping procedure or terminal-approved transfer rate. Actual discharge performance depends on cargo viscosity and temperature, vapour pressure, tank level, suction conditions, pump curves, line losses, terminal backpressure, valve configuration and operating procedures. Use vessel-specific pump curves, terminal requirements and approved tanker procedures for execution.
