This publication is a guide to stability and ballast control on board semi-submersibles and jack-up type craft. It begins with an overview of stability theory and principles, before going on to look at:

 

  • Transit theory
  • trim list and associated problems
  • daily stability calculations
  • ballast control equipment and associated systems
  • ballast and deballasting operations
  • training of personnel

Volume 7 of the series is aimed at those personnel on semi-submersible vessels and jack-up type craft responsible for the control and maintenance of that most fundamental parameter required of the majority of craft, namely to stay afloat and upright.

 

This is not a detailed study of ship stability, those readers interested in the subject may wish to consult the books noted in the Bibliography. Only sufficient theory and principles are given to enable personnel to understand the basis on which daily calculations are made and how to apply theory in particular situations.

 

The specialised craft under consideration are commercial vessels operating in an often extremely harsh environment. In order to earn their keep they are expected to perform to their design specification in terms of carrying capacity and working limits. Optimum conditions can only be reached if the practice of Stability Control is understood and applied. Neglect of Stability Limitations and failure to understand the implications of overloading, loss of stability margins due to damage and attempting to make vessels operate out their design envelopes (in stability terms) has led to losses of both men and vessels or to serious damage. In commercial terms mistakes and neglect of weight control have led to the cancellation of charters.

 

Ballast Control Practice as applied specifically to semi-submersibles, has in the last few years been given the importance which it deserves, in terms of the amount of training those doing the work need and the design characteristics of ballast control systems. Ballast Control Operators are usually the same personnel that carry out stability calculations and weight control. It is no accident that these functions are combined and in fact it is better that they are, provided the data on current and projected stability conditions which they supply is understood by those in charge of the vessel. Sadly, this has not always (and is still not) been the case, with tragic results. Some Port States have introduced specific legislation in terms of qualifications and knowledge required by those in charge of these specialist craft and the training requirements for Ballast Control Room operators, Barge Engineers etc., but such legislation is not always rigorously policed. The offshore oilfield is particularly prone to the habit of attempting to abide by instructions issued by senior, often shore based managers, which in terms of operational safety and good practice are impossible to carry out. Some of these senior staff may benefit from a study of this volume.

 

The book is aimed primarily at Barge Masters, Barge Engineers and Control Room Staff. It is hoped that it can be used as a training and reference book for personnel new to the peculiarities of oilfield specialist vessels.
