Design of Marine Facilities for Berthing, Mooring and Repair of Vessels.

---

This book is a useful addition to thc lorc of the marine engineer who designs shoreside or offshore facilitics for ships. It brings together in a single source a synopsis of thc vast number of detailed considerations that face the designer who must fashion a conncction bctwecn thc moving object, the ship, in its flotation mcdium of waves, currents, and winds, and the fixed structures at ports and docks.

The author has madc a shrewd sclection of facts, physical theory, and accepted engincering practice in order to give as complete a description as possible of the main tasks, without entangling the designer in a web of uncertainties—and the uncertainties in marine engineering begin with our imperfect understanding of the behavior of water, air, and harbor mud, and how they interact with fixed and floating structures.

Marine engineering is a branch of civil engineering, which in turn started with military needs several thousand years ago. It was built on empirical knowledge, ingenuity, and, little by little, science whenever it was helpful. Ingenuity is still a vital ingredient (consider the recent development of the tension leg mooring for offshore oil platforms) and the science is still growing at an exponential rate. |

When the author needs to provide more detailed information, or where the reader wants to know more about the background of a particular theory or code of practice, there is at the end of each chapter an extensive list of references. Incorporated in the text are many formulge and tables taken from these references. The figures are plentiful—some 250 or more, both photographic and graphic—to illustrate and simplify understanding of the text.
The focus of the book is clearly on facilities, and how to go about designing them. The book deals with ports, but it is not all about ports. Instead, it is about the structures that are needed at a port in order to make a ship useful. There is just enough information about oceanograpky, port siting and planning, economics, navigation, channels, breakwaters, dredging, shore processes and cargo handling to make it clear how facility designs fit into the marine industry, without diverting away from the designer's tasks. But in going about those tasks, the way is made clear.
One of the difficulties in marine engineering is the very breadth of the subject,
and the diversity of disciplines one must encompass to understand the variables.
and the choices that are possible. The menu includes geography, geology, ba. . thymetry, geotechnics, soil mechaniecs, strength of materials, corrosion, fluig mechanics, dynamic interaction, naval architecture, hydraulics . . . in almost endless array. To find the appropriate data to suit a particular site and a specific design often reguires extensive research. This book succeeds very well in short: Sning the search. It organizes information in a logical seguence, and points out where to gct what is missing. .
Many aspeccts of marine facilitics change so rapidiy that a text can only be Current if it is freguently modified. Part of the transitory nature of the science and art of marine design is the result of advances in materials and knowledge, but most of it is caused by changes in the needs of the industry. For example, drilling for oil and gas under water has changed in forty years—from marshes, Where water isa few feet deep, and dredging is reguired to provide flotation for a small drilling barge, to 1700-foot depth for a recent mammoth tension leg platform in the Gulf of Mexico. Finger piers built 50 years ago for general cargo have become obsolete, and have been abandoned in favorof marginal wharves, cach with 100-acre upland parking areas for containers, or for imported automobiles, sorted for transport on 18-wheelers and double-decked trains. Military piers built for the heavy loads of 16-inch gun turrets 47 years ago stand unused, and are being converted for bulk material conveyors. Marinas replace cargo sheds. Dockominiums, pleasure boats and apartments stand where railroad carfloats used to berth. Timber piling, which used to be protected from marine borers in many harbors by the polluted water, is again under attack as the waters become cleaner.
One of the changes produced by time is the language in common usage. For example, Chapter 8 in the book is headed ““Geotechnical Design Considerations.”' The key word, georechnical, is guite new. Only a few years ago, we had “soil mechanics”' and ““foundation engineering,” as introduced into the United States by Karl Terzaghi. Today's technigues, using computer programs to model pile-soil systems and slope stability forces, have brought a new perspective. But the judgment factor in assigning coefficients is still essential, and this is recognized by the author.
Many books about the marine industry, or about ports and harbors, try to cover the entire field of subjects related to the sea, from oceanography, waves, storms, beaches, erosion, sedimentation, navigation, and on into breakwaters, channels, ship behavior, commerce, rivers, estuaries, locks, canals, dams, and so on. This is too diverse a subject matter to explain in any detail in one volume and still remain concise enough to be useful.
The increasing specialization of scientific and engineering knowledge has scattered the sources of information and the findings of research. It is a worldwide explosion of data. The designer of marine and waterfront structures needs to synthesize these sources from many disparate disciplines in dealing with his craft. There is no internati ational codificati ations.
