The Art of Dredging

Dredging and shipping

Book review "Adverse physical conditions & the experienced contractor" by David Kinlan








So much dredging literature is superficial; or banal: seldom does a book delves to the bottom of a subject, and shares depths of knowledge to the world.



"Adverse physical conditions & the experienced contractor" is all about knowledge sharing: how to avoid the pitfalls of unforeseen physical conditions (think geo-, meteo, - etc...) from a contractual and engineering point of view ? Or, if stuck with them; how to make the best out of it ?


From the perspective of the major international dredging contractors, the consequences of encountering “adverse physical conditions” during a dredging or marine construction project have long been obvious.

There is a huge void on literature examining the “unforesee-ability”of these conditions from an engineering and contractual perspective.

This book aims to assist those practitioners who have to formulate, manage or otherwise  avoid claims for adverse physical conditions on marine infrastructure projects.

Not all physical conditions on the site will be discovered until the operations are actually underway.

And once they are encountered, these adverse physical conditions can be the source of costly conflicts. Even though, with hindsight, most are found to be unforeseeable and unavoidable.

How can we best deal with these unforeseeable conditions? How can contractors and clients avoid lawyers, claims and recourse to the courts to solve disputes? All these subjects are touched upon in David Kinlan’s book.

This book does not deal with the operational side of this problem, but digs deep -like bedrock deep- into the contractual, engineering and claims side, either to prevent unforeseen situations, or -if encountered- to make the best out of that situation.
