Methods for assessing the seakeeping performance of high speed displacement monohulls and catamarans

Methods for assessing the seakeeping performance of high speed displacement monohulls and catamarans
Methods for assessing the seakeeping performance of high speed displacement monohulls and catamarans
The research programme has investigated methods for assessing the seakeeping performance of high speed vessels. This has included a review and assessment of seakeeping attributes, the development of a suitable database of motion characteristics using experimental and numerical techniques and proposals for assessing the seakeeping characteristics of alternative vessels. An experimental test programme was carried out in regular head and oblique waves as well as irregular open seas on two different hull forms of fast displacement catamarans. The results of the experiments in oblique waves are extended to beam and foUowing headings using the transfer functions &om a 3D pulsating source code at headings from head to following seaa in regular waves. This eSectively provides a meajis of generating 3D transfer functions. The methodology used to compare and assess the seakeeping performance of vessels at an early design stage is discussed. The use of short crested seas as opposed to long crested is assessed and the differences compared. This leads to the use of spreading relationships to generate 3D transfer functions from the database of transfer functions in regular head waves. This allows the motion prediction method to be greatly enhanced by ciHowing any heading to be assessed. The proposed attributes and criteria suitable for assessing the seakeeping performance of high speed vessels are summarised.

Abstract

The research programme has investigated methods for assessing the seakeeping performance of high speed vessels. This has included a review and assessment of seakeeping attributes, the development of a suitable database of motion characteristics using experimental and numerical techniques and proposals for assessing the seakeeping characteristics of alternative vessels. An experimental test programme was carried out in regular head and oblique waves as well as irregular open seas on two different hull forms of fast displacement catamarans. The results of the experiments in oblique waves are extended to beam and foUowing headings using the transfer functions &om a 3D pulsating source code at headings from head to following seaa in regular waves. This eSectively provides a meajis of generating 3D transfer functions. The methodology used to compare and assess the seakeeping performance of vessels at an early design stage is discussed. The use of short crested seas as opposed to long crested is assessed and the differences compared. This leads to the use of spreading relationships to generate 3D transfer functions from the database of transfer functions in regular head waves. This allows the motion prediction method to be greatly enhanced by ciHowing any heading to be assessed. The proposed attributes and criteria suitable for assessing the seakeeping performance of high speed vessels are summarised.
