NALCO subsidiary Nalfleet has launched a new range of cleaning products for wastewater membrane separation systems. The new Permaclean range mainly comprises three types of treatments: antiscalants; cleaning products; and biocides. Antiscalants prevent deposits building up on the membrane, while cleaning products remove foulants such as mineral scale or organic fouling and biocides minimise the impact of biogrowth. If reduced membrane performance is not solved


by these treatments, Nalfleet offers a chemical, physical and microbiological analytical service to determine the cause. Nalco is the world’s largest water and process treatment provider and Permaclean products are available for black, grey, and oily water applications.

BOOK REVIEW 50 Years a Shipbuilder


By Patrick G Martin. Published by The Memoir Club, Stanhope Old Hall, Stanhope, Weardale, County Durham DL13 2PF, UK. 454 pages. Softback. ISBN: 1 84104 156 4. £19.50 or €25.00. Available from the RINA bookshop: £19.45 for RINA members (UK, including postage). In recent months and years, we have published several reviews of both autobiographies and biographies of prominent personalities in the marine world, and this new publication is equally fascinating. For those closely associated in the various subjects and events discussed, the text could even be said to make gripping reading. Patrick Martin counts himself among that


relatively select band who are members – or in his case, Fellows - both of The Royal Institution of Naval Architects and what is today the Institute of Marine Engineering, Science & Technology; he will perhaps be best remembered when he was chief naval architect at the now sadly closed Verolme Cork Dockyard. Here, he was responsible for several interesting projects, including a bulk carrier for Irish Shipping powered (against his judgement) with medium-speed engines geared to a single CP propeller – considered revolutionary in the early 1980s. This arrangement was subsequently confirmed to be less efficient than if a standard two-stroke, direct-coupled machinery had been specified. The Irish dockyard also built an interesting series of passenger/vehicle ferries for British & Irish (B&I) Line, including ‘the most difficult and most worrying ship design projects’ of

his career – the sisters Connacht and Leinster of 1979 and 1981, as well as some smaller naval vessels. Nevertheless, for this reviewer, it is the other


sections of the autobiography that are most intriguing, especially since the author appears to have kept a meticulous diary throughout his career! Patrick Martin served his apprenticeship


at an old-style Scottish yard, Burntisland Shipbuilding, where all contract negotiations were handled by the chairman and managing director, Sir Wilfrid Ayre, and design information was sometimes passed to the drawing office on the back of an envelope. He also recounts, among many fascinating details, the day when a ship was accidentally launched in advance when an apprentice dropped a spanner onto a bell push which would signal to the shipwrights that it was the moment to release the launch triggers… The author was clearly a determined man:


at the end of his apprenticeship, he chose, on his own initiative, to spend several years at sea – as a marine engineer – in order to gain valuable experience of design work. This will be music in the ears of those today (including The Naval Architect) who still believe that all trainee naval architects should serve some sea- time, as indeed members of the Royal Corps of Naval Constructors did, including this journal’s regular reviewer, Eric Tupper. Mr Martin succeeded in persuading Alva Steamship Co to allow him to serve as seventh engineer on a tanker Alva Star and later on a cargo ship Pearlstone (‘I wanted experience, not tickets’) and with Alfred Holt’s Blue Funnel Line passenger/cargo ships Atreus and Anaeus;


his stories make absolutely fascinating reading – both technical and general. After this intriguing episode, the author was seconded to Caledon Shipbuilding, in Dundee, where a new Alfred Holt ship was under construction. His text records, in passing, the sad decline of Britain’s (and Ireland’s) once proud shipbuilding industry. When Verolme Cork Dockyard closed in


1984, Patrick Martin thought his shipbuilding days might be over, but he found re-incarnation in life as a consultant. He was particularly involved in a revolutionary concept that was being proposed at that time: the hatchcoverless containership. He became intimately involved in the creation of the 301TEU prototype Bell Pioneer (The Naval Architect July/August 1990, page E313) for the Irish owner Bell Lines; he travelled extensively to Australia, where the hatchcoverless concept had been created by Commodore Tom Fisher and Fred Ellis, of Advanced Ship Design, also to China, where the models were tested at then little-known Wuxi basin, and to Japan, where Bell Pioneer (and a sister) were eventually built, at the modest Teroaka Shipyard on Awaji Island. The protracted negotiations with authorities prior to contract, and details of both construction and sea trials are all faithfully recorded. There is a good selection of mainly black-


and-white general illustrations, plus some highly interesting detailed ones – including a few of ships negotiating heavy weather, with extensive captions in an appendix. This whole book makes totally absorbing reading and can be highly recommended.


Tim Knaggs 91 LEAP to agreement


LEADING Engineering Application Providers (LEAP), Australia, has reached an agreement with Beasy, a software applications producer, to distribute Beasy’s program simulating the life and performance of products. Applications include mechanical analysis (stress and thermal), durability and crack growth analysis, corrosion and cathodic protection, corrosion related electric and magnetic fields, and acoustic design and noise control. Dr Robert Adey, managing director of Beasy,


said the deal would benefit customers of both companies. His counterpart at LEAP, Greg Horner, said that Beasy software complemented LEAP’s existing offerings and strengthened its capabilities in areas such as fracture mechanics and signature optimisation. Contact: Dr Robert Adey, computational

SAM Electronics has introduced two high precision R4 GPS and enhanced Differential GPS


sensors. Designed for worldwide navigation and hydrographic survey support, both units are approved by EC Wheelmark, the United States Coast Guard, and the International Maritime Organization. The design features two interface channels, and compact shock resistant systems, with small receivers and antennas to facilitate installation. Both units are compatible with satellite augmentation services such as Wide Area Augmentation System (WAAS), European Geostationary Navigation Overlay Service (EGNOS), and Multi functional Satellite Augmentation System (MSAS) from Japan. Dual Station capability and Receiver


Autonomous Integrity Monitoring (RAIM) ensure GPS accuracy, and units have sunlight- readable displays. Antennae are designed to reduce onboard transmitter interferences, plus the Differential GPS version supports International Association of Lighthouses (IALA) beacon signal corrections.
