An Explanation and Guideline for Pumping Calculations

A common source of a Tanker Charter Party demurrage dispute is the alleged non-compliance with the warranties contained in a Pumping Clause of the Charter Party. This publication defines and explains the basis for the undertaking of the relevant calculations pursuant to the requirements normally set out in a standard pumping clause of a Tanker Charter Party together with an analysis of the meaning of the terms of the pumping clause.

The publication identifies the origins and basis for the equations used and their application within the calculations required to determine the rate of discharge from a tanker given the diverse parameters and their functions within the equation. Worked examples of the diverse calculations are provided as guidance for the undertaking of the calculations together with suggestions as to alternative methods for the monitoring of the efficiency of pumping of cargoes.

Explanation is also provided in order to understand the impact upon pumping of placing pumps in series and parallel (the impact of a shore booster pump) with regard to the recorded pressures and rate of flow during a discharge operation.

Multiphase Crude Oil Cargo Guidelines

The objective of this document is to provide tanker officers with methods and information that can assist with a more effective and efficient transport and handling of crude oil cargoes with respect to:

  • vapour pressure release from tankers, minimising the impact of vapour or sludge on cargo operations with a fully laden crude oil tanker
  • less cargo remaining on board after discharge when transporting some of the more difficult types of crude oils
  • minimising loss to the atmosphere during transportation of more volatile crude oils

The methods described are generalised but will supply indications of the expected behavioural characteristics of specific crude oil types and may serve as guidelines to improved operational decisions during transport and discharge.
