The Chesapeake Section of the Society of Naval Architects and Marine Engineers (SNAME) and The American Society of Naval Engineers (ASNE) presents “Practical Seakeeping” by Dr. Ed Lewandowski.
WHO SHOULD ATTEND: Professionals and managers involved in ship design and integration. This course is only open to US citizens
DESCRIPTION: This course will provide the background necessary to understand seakeeping specifications and reports. After a general discussion of performance requirements, the specification of the wave environment will be described, including definitions of sea states and wave spectra as well as identification of sources of data. Determination of the ship response to the waves will next be explored, including use of model tests and prediction tools; the available tools will be described and compared. Quantitative measures of seakeeping performance, including absolute and relative motions, motions-at-a-point, slamming, MSI and MII, will be defined. Use of these quantitative measures in conjunction with performance criteria for the development of operability indices will be explained. Finally, several examples will be considered, including a detailed examination of a seakeeping test report and development of an operability index.
