Anti-Corrosion Methods and Materials: Volume 13 Issue 5

Surface preparation in the shipyard

J. Jackson

Keeping a ship properly painted costs the owner a lot of money; the builder, repairer, and paint chemist a lot of headaches. Whether the paint stays on or not depends to a great…

How offshore drilling rigs are protected

L.H. Bridges

Offshore drilling rigs have been operating for many years, but it is only fairly recently that they have been used much in British and European waters. Conditions in these waters…

The design of hull anodes for protection by impressed current

J.H. Morgan

IMPRESSED CATHODIC CURRENT for ships' hull protection by two techniques has been proposed, firstly by trailing a wire either from outriggers amidships or over the stern and…

Electrolytic corrosion and cavitation

This article is based on information compiled by the Perkins Engines Group materials laboratory at Peterborough for use in the company's own marine engineering activities. It…

Impressed current cathodic protection of ships

E.P. Anderson

ENGELHARD INDUSTRIES have, for the past 15 years, been particularly interested in the subject of impressed current cathodic protection of ships' hulls. A study we made convinced…

Pretreatment and priming of steel

Ir. J.H. de Vlieger

The author discusses several examples of paint systems that failed, not because of the quality of the paint, but from defects or complications during application. Metal…

How to get good results when painting aluminium

When used as a structural material, aluminium is often left with a natural surface or given a coloured anodised finish. However, it is also necessary to apply a protective or…

FASTENERS: FOR MARINE ENGINEERS

P.E. White

SAFETY is uppermost in the minds of all who travel by sea, and the use of reliable materials and methods of boat construction is essential in establishing confidence. The use of…

A plastic hull in tough marine service

THERE ARE NO alongside wharves for ocean‐going vessels at Aden, so all cargo handling is done by tugs, lighters, launches and similar vessels. The conditions in which these craft…

On scale/metal entanglement in low‐alloy steels

K. Sachs, C.W. Tuck, J. Barlow

The first part of this paper was published in the April issue. For convenience Figures 1 and 13 have been repeated here from part 1 as frequent reference is made to them

Eight‐year test for anti‐corrosion coating

THE PAINT CHEMIST can get some idea of the long‐term performance of materials from accelerated techniques such as the weatherometer, salt‐spray and SO2 tests. However, the actual…
