Journal of Ship Hull Performance, Vol 2, Issue 3

The August 2012 issue of the Journal of Ship Hull Performance includes Hydrex White Paper No. 11 which opens the door to a ten year drydocking interval, at least from the hull protection and biofouling control point of view. 

This issue of the Journal also includes excerpts from a thesis by Capt. Charles Assifuah on the subject of Ecospeed, and its value to merchant shipping as the ideal underwater hull coating system. 

The introduction to the soon-to-be-released Surface Treated Coatings White Book is publised in full in this issue of the Journal.

Quantification of Pollution Levels in Harbour Sediments

A GeoSpatial Perspective

By Steyl et al

Quantification of Pollution Levels in Harbour Sediments – A GeoSpatial Perspective is the result of a preliminary research project commissioned by Hydrex to quantify and map the levels of pollution in sediments around the world, with particular regard to the heavy metals and toxic substances contained in ship hull antifouling paints. The preliminary project is intended to be the precursor of a complete, ongoing inventory of sediment contamination around the world for use by environmental managers and by legislators and regulators responsible for the marine environment, its health and sustainability. The book helps answer the question “Should we continue to use the currently available biocidal ship hull antifouling paints?”

About the Authors

Prof. Sakellariadou is a professor in Geochemical Oceanography in the Department of Maritime Studies, University of Piraeus, Greece. She gained her PhD at the University of London and is the author of the book Oceanography.
Dr. Bray is a marine ecologist and visiting researcher at the University of Southampton where he gained his PhD. He was commissioned by WWF to carry out extensive research on the effects of TBT which contributed to its eventual ban by the IMO.
Dr. Bill Langston, who reviewed the report, is an Associate Fellow and Head of the Ecotoxicology Laboratory at the Marine Biological Association of the UK. He is a world renowned and much respected ecotoxicologist.

Surface Treated Composites White Book

A proven, non-toxic, cost-effective alternative technology for underwater ship hull protection and biofouling control

By Boud Van Rompay

The Surface Treated Composite White Book is a description of a better, alternative, non-toxic, cost-effective, environmentally safe technology for protecting the underwater hulls of ships and keeping them free of biofouling. “Alternative” because it takes a 180° opposite vector to the generally used, conventional systems of painting the underwater hulls of ships with highly toxic heavy metals and biocides as a means of protecting the hulls and keeping them clean. “Better” because its standard application can reduce the cost of maritime transport significantly while greatly lowering the environmental impact of shipping.

 

This alternative technology begins with the premises that the marine environment should be kept clean and free of toxic chemicals which pollute the water and contaminate the sediment, that shipping should be able to operate and expand without harming or destroying the very environment on which it operates, that there is a non-toxic answer and that that answer is also the most economical way to sail. 

The Surface Treated Composite White Book is essential reading for anyone who has any connection with protecting the underwater hulls of ships, who is responsible for operating ships economically, for reducing the impact of shipping on the environment. Shipowners, ship operators, officers, naval architects, ship builders, the IMO, government officials responsible for maintaining a sustainable marine environment, officials in charge of navies and government owned and operated fleets, NGOs, shipyard operators, anyone who has any interest in or responsibility for the efficient and ecologically sound operation of ships and shipping. 

The book is the result of 40 years of research, development, study and practical application and experience added to the wealth of information on the subject which has been researched and recorded by caring and intelligent minds around the world.
