THE TREDEGAR DRY DOCK, NEWPORT, MONMOUTH.

Design of Inner Gate for CRIST Shipyard Dry Dock

The paper deals with a removable steel inner gate which was designed to separate two parts of a dry dock of about 70 m in width and 380 m in length. The gate allows for independent assembly of ship structures in the two separated parts of the dock. The fore part of the dock can be flooded while the after part is dry. The gate was designed by IDEK Company Ltd in 2011 and it was soon constructed ...

The dock problem revisited

The dock problem (cf. [2], [4, 5]), which is that of understanding the scattering of surface water waves by a thin semi-infinite rigid plate floating on the free surface of water of infinite depth, gives rise to the following mixed boundary value problem, involving Laplace’s equation in two dimensions, with (x, y) representing the rectangular Cartesian coordinates, assuming linearised theory of...

The finite dock problem

The scattering of water waves by a dock of finite width and infinite length in water of finite depth is solved using the modified residue calculus technique. The problem is formulated for obliquely incident waves and the case of normal incidence is recovered by taking an appropriate limit. Exciting forces and pitching moments are calculated as well as reflection and transmission coefficients. T...

John Newport 1951–2005

The news is so full of lives cut short that one might worry that we have become inured to the experience. But cold reality asserts itself when a premature death strikes within our own community, and the full tragedy and the wasted opportunity are exposed. We then pause to mark the singularity of human existence and the personal nature of science itself. John Newport, distinguished professor of ...
