LETTERS TO THE EDITOR Green backlash
Dear Sir, Re: editorial comment - Jan 09 – Scrubbers, Mr Winkler. We wish to comment on your editorial comment in respect of Mr Winkler’s idea of marine scrubbers. It is mentioned by Mr Winkler that
these scrubbers need not cost “more” than US$1 million. Considering about 90,000 ships we end
up with an investment of US$90 billion, which is an astronomical figure. Why not install huge scrubbers at the
refineries to start with? Tis would be a lot cheaper. Did Mr Winkler note that the yard
which built for Maersk those ships with scrubbers, just went under? Where does he find an owner who will add in today’s market US$1 million without any incentive to do so? Are all owners part of a charity organisation? Who will pay for that, and
which yard will volunteer to add this cost when no ships are ordered presently? We are all concerned with our
environment but the measures taken should be economically sensible and viable. Let alone the cost issue, has Mr
Winkler given thought to the gradual accumulation of sulphur in the ocean waters through the scrubbing of the fuel? What will the “fish” say? We thought that this way of thinking was long abandoned by us trying to keep the oceans clean.
Capt Amos Cohen Antares Shipping Ltd.
Dear Sir, I was interested to read the article in this January’s ‘Te Naval Architect’ about the experimental ship with an air cavity system along its double bottom. In the
early 1950s I discovered, in the basement of Alexander Stephen and Son’s Shipyard office, papers relating to a patent for releasing air bubbles to reduce a ship’s bow wave. I do not know if the idea was ever tried, but the patent was considered to be of no value. Our patent was held jointly with the
designer and inventor John Tutin who patented hatchcovers and stabiliser fins and designed the rudder for the Queen Mary. His daughter, the late Dame Dorothy Tutin who was one of my favourite actresses, felt that her father never got the recognition he deserved. For some extraordinary reason we also held a patent for a Tutin Teapot. I hope the air cavity system proves more successful than the Teapot.
Yours Sincerely Alexander Stephen
