Page 18 - Pipeline Pigging Technology

Readers will find in this book papers that cover subjects more diverse than
simply the practicalities of pigging. I make no apology for this, as the basic
requirements for pigging have now to be seen in a wider context, the
boundaries of which are increasingly being set by legislation. Concepts such
as 'fitness-for-purpose' and 'integrity management', the practical develop-
ment of which will allow an operator to manage his pipeline with greater
precision and safety, will nevertheless be based on data obtained from
successful pigging operations.
On page xii will be found a list of the contributors, together with
references to the conferences at which their papers were originally pre-
sented. I am greatly indebted to all these authors, both for their willingness
to participate in the conferences, and for their agreement to allow their
papers to be published in this book.
It should be explained that, although edited as far as possible into a uniform
appearance, the papers appear here in the same form as that in which they
were originally presented. Any errors are, of course, my own.
