BEASY CP (Version 8.1) has been found to be an extremely useful
computational tool for calculating both corrosion-related surface potentials and
underwater electrostatic fields or UEP signatures of warships.
In this review
paper we have created and examined an hypothetical model of a prospective
high-speed amphibious lift craft.
The paper sets out for the reader the means of
how we optimise the boundary element software to both perform
essential modelling and extract key data relating to surface potential and UEP
This is a review article which intends to cover or highlight some of the practical
applications of the boundary element technique, particularly when at this point of
time, we recognise an acute requirement for rapid, accurate and innovative
advice for our respective military directorates.
As will be demonstrated, the boundary element method (BEM) is a very
useful tool for the theoretical examination of corrosion patterns and underwater
electric potential (UEP or static electric) signatures of ships and submarines.
Therefore, the review, as with many other of my past papers, will focus on a
hypothetical naval platform; a catamaran system.
The operational feasibility of a
high-speed catamaran for the purpose of providing fast amphibious lift, that is,
conveying troops rapidly from ship to shore, was investigated in 1999–2001 by
the Royal Australian Navy (RAN) through the deployment of HMAS Jervis Bay.
During its two-year service period, this platform showed to be a very efficient
and effective system.
