A few of them have been assigned terms in archaeological publications the rest I hope I have anticipated and defined accurately. I have tried to sort out this confusion where possible.Īncient ships contained structural arrangements that had disappeared by the medieval period, and therefore they remain unlisted in publications. One marine dictionary shows the knee of the head as being located behind the gripe, while most of the others call this timber an apron and properly place the knee of the head just below the bowsprit. The confusion extends to modern publications. However, the reader is cautioned that many of the timbers and devices listed here might have had additional identifications, often the invention of the writer or in local slang some difficulty may be experienced in identifying such entries in various documents. Alternate definitions for a single entry are commonplace this is the result of diffusion, varying localities, and technological progress. Alternate terms or spellings are listed in brackets after the entry. Entries have been illustrated wherever possible, either within the glossary or in the text. The fundamentals, analysis tools, and existing research and development issues for these topics are given.Words set in bold type are defined elsewhere in the glossary.

Sample topics that might be discussed include the design and operation of autonomous underwater vehicles, wave impact and ship slamming, or structural integrity of pipelines and risers. The advanced topics are not needed in order to carry out the design project for this course. These topics are chosen by the students based on their interest in ocean science, naval architecture, and offshore structures. Ways in which to improve the efficiency of fabrication are also discussed. The basic requirements and procedures in the fabrication and installation of ships and marine structures are discussed. Two lectures are devoted to this subject. The general procedure in mooring system design is taught. An analytic solution for the static analysis is given. The basic dynamics of a catenary mooring line are first introduced. Mooring Dynamics and Designģ-4 lectures are given on this subject. Approximate formulas for the evaluation of slowly-varying loads/motions are provided. The characteristics of drift and slowly-varying loads/motions and its implications to the design of floating structures and mooring systems are then discussed. The basic nonlinear mechanisms for drift loads/motions and slowly-varying loads/motions are explained. Drift and Slowly-Varying Loads/Motionsģ-4 lectures are given on this subject. The numerical boundary element method for the sea-keeping computation is briefly explained. The influence of resonant frequencies on the motion of a floating body in an irregular sea is discussed. The spectrum of the body response in irregular waves is given. The RAO of a floating body is derived in terms of the basic hydrodynamic coefficients. A long-wave approximate solution for the diffraction problem is derived and used to illustrate the characteristics of wave excitations. Characteristics of the added mass and damping coefficients are discussed. The basic formulation for the radiation, diffraction problems are given. Seakeepingįour lectures are given on this subject, which is critical to the description of the dynamic behavior of floating structures in waves. Short-term statistics of ocean waves are studied for applications to the design of ships and offshore structures.

First, there is a discussion of the kinematics and dynamics of regular waves, then a description of irregular wave and wave spectrum of irregular seas. Three lectures are devoted to this subject. The development of a midship section is also taught. Then, a ship structural analysis follows, including the calculation of loads, shear forces, bending moments, and buckling.

First, general concepts are taught such as the mechanics of beams, torsion of closed shafts, and elastic stability of columns. One lecture is given on the structural analysis of ships. The use of criteria for the stability assessment is also discussed. Righting arm curves and other similar concepts are presented both for intact and damaged stability. Ship hydrostatics is reviewed and stability analysis is explained. A presentation on the general characteristics of ocean systems is given followed by a specific presentation on FPSOs. Terminology and methods for generating ship lines are presented. The lectures start with an introduction of basic naval architectural concepts. Lecture notes for sessions 17-26 are not available. On selected topics are listed by session in the table below.
