This publication provides detailed guidance on chemical tanker practice, from commencement of the voyage until its completion. It includes stowage planning, tank cleaning, loading, conditions of carriage, ballasting and discharge. The appendices provide useful reference material on chemical compounds, storage compatibilities, IMO regulations, record keeping and the Shipboard Marine Pollution Emergency Plan (SMPEP).

This book looks in turn at every stage of a chemical voyage, including:

  • The importance of product identification and how this affects stowage, segregation and handling
  • methods of tank cleaning and testing
  • loading rates and temperatures, sampling, cargo calculations, deballasting, cargo tank vapour return systems
  • conditions of carriage – heated cargo, nitrogen blanket cargo, recirculation, inhibited cargo
  • preparations for arrival, pumps and discharge procedures, ballasting
  • prewashing of tanks and piping systems.

The text is supported with over 40 ‘experience boxes’ based on the author’s own observations and experience. These provide additional practical guidance and highlight potential hazards when handling chemical cargoes.

There are many operations that are carried out simultaneously onboard a chemical tanker, such as loading, discharging, tank cleaning, gas freeing, ballasting, deballasting and so on. However, the main rule onboard any tanker is that all operations are to be conducted in a competent and professional manner.

Certain operations must be suspended if there is any threat or likelihood of loss of control.

The chemical tanker fulfils the most extreme idea of customer satisfaction by offering ‘Just in Time’ (JIT) transport of a multitude of liquid cargoes.

The availability of tankage, the substances being loaded or discharged and quite often the need for the tanks to be discharged, cleaned and then loaded with another substance all are causes of a series of logistical problems.

This book is designed to provide some answers on ‘what to do’ and ‘how to do it’ for officers and cadets on chemical tankers. The subjects are organised in the order that they occur, from the receipt of voyage orders to the completion of cargo discharge and the practice of pre-wash.
