12、)A manual or report in this series consists of an orderly presentation offacts on a particular subject, supplemented by an analysis of limitationsand applications of these facts. It contains information useful to theaverage engineer in his or her everyday work, rather than findings thatmay be useful

13、 only occasionally or rarely. It is not in any sense a“standard,” however; nor is it so elementary or so conclusive as to providea “rule of thumb” for nonengineers.Furthermore, material in this series, in distinction from a paper (whichexpresses only one persons observations or opinions), is the wor

14、k of acommittee or group selected to assemble and express information on aspecific topic. As often as practicable the committee is under the directionof one or more of the Technical Divisions and Councils, and the productevolved has been subjected to review by the Executive Committee of theDivision

15、or Council. As a step in the process of this review, proposedmanuscripts are often brought before the members of the TechnicalDivisions and Councils for comment, which may serve as the basis forimprovement. When published, each work shows the names of thecommittees by which it was compiled and indic

16、ates clearly the severalprocesses through which it has passed in review, so that its merit may bedefinitely understood.In February 1962 (and revised in April 1982), the Board of Directionvoted to establish a series titled “Manuals and Reports on EngineeringPractice,” to include the Manuals published

17、 and authorized to date, futureManuals of Professional Practice, and Reports on Engineering Practice. Allsuch Manual or Report material of the Society would have been refereedin a manner approved by the Board Committee on Publications andwould be bound, with applicable discussion, in books similar t

Robertson recommended that a task committee be establis

24、hed toprepare a document on mooring analysis for fixed piers and wharves. Anew committee proposal was submitted in December 2001, and the firstmeeting of the mooring analysis task committee was held in March 2002.Robert Robertson was selected as chairman and Martin Eskijian assecretary. The committe

25、e discussed many topics and issues and addedmuch since the original series of meetings. In April 2007 the chairmanshippassed to John W. Gaythwaite at the direction of the Ports and HarborCommittee of COPRI, and the focus of the group subsequently became thedevelopment of an ASCE Manual of Practice (

26、MOP) for the mooring ofships at fixed harbor facilities.The purpose of this MOP is to provide designers of piers and wharvesand other fixed marine facility structures with the necessary backgroundand resource information to ensure that their structure designs are soundand adequate and provide a safe

27、 berth for the types of vessels to beaccommodated. This is necessary because currently no single buildingcode or standard specifically addresses the design of berthing andmooring facilities in general, and the guideline documents that do existhave varying requirements for specific facility types. In

28、 addition, manycostly mooring incidents have occurred, emphasizing the need for a betterunderstanding of mooring design principles. The chairman wishes tothank all of those involved in this process and trusts that the guidanceprovided herein will provide useful and timely information to the portengi

45、upon piers, wharves, and other fixed structures such asberthing and mooring dolphins due to berthed vessels and to providebackground for safe and efficient fixed mooring design practice. Theultimate goal is to provide vessels with a “safe berth” with adequate andsound mooring structures and arrangem

46、ents. This manual is not,however, intended to be a complete, standalone mooring analysis andpier design document, because the subject matter is too complex and thevariety of vessel and facility types with specific requirements is too wide.The reader is directed to the various important documents tha

47、t cover theseareas as introduced in the last section of this chapter and referred tothroughout this manual.Ships were once much smaller than they are today. Ports providedmooring accessories on wharves and piers based on a local standard,which proved adequate through many years of experience. Ship c

48、aptainsand pilots could direct the line handlers to tie up a ship in accordance withyears of experience as mariners and based on tradition. However, shipsbuilt today are increasingly larger and more complex such as tankers,container ships, roll on-roll off (RO-RO), ships, bulk carriers, cruiseships,

49、 military vessels, etc. These ships typically have a larger areaexposed to wind and deeper draft hulls exposed to current and passingship effects. Old standards and methods are often inadequate, andanalytical methods have been developed to determine mooring forces andoptimize the arrangement of mooring lines. Safe mooring also includes1limiting the movement of the ship in berth. Preventing parted lines andship breakaways is another goal of performing a mooring analysis.This Manual of Practice p
