Further to the article published on 13 December 2000, MarineTalk’s correspondent would like to finish his review. Three presentations of particular interest to shipyard operators, and to naval architects and civil engineers specializing in yard layout and construction, were Don McLean’s overview of progress at Lisnave, Geoff Stokoe’s on transfer systems, and Adrian Arnold’s on the civil engineer’s role in yard design, modernisation and maintenance.
McLean described Lisnave’s new ULCC facility that includes a transfer dock and three above-ground-level working docks. More details on such things as pumping rates would have been welcome, as well as economical considerations which lead to this interesting solution of the multi-vessel capability requirement. Otherwise a very interesting paper.
Stokoe, president of Synchrolift Inc., gave an excellent and well-illustrated summary of the main mechanical transfer systems in use, concentrating as might be expected on the bi-level and single level carriage and rail systems developed by his company to complement their well-known platform-and-winch ship lifts. When invited by the moderator to comment on Lisnave’s choice of floating transfer for their new system, he declined, which was a pity. As mentioned above, a frank and open discussion on the capital and maintenance costs, site-specific and other technical limitations, and operational considerations such as disposal of grit and old paint, tank contents, etc., and access to work areas, which affected Lisnave’s choice would have been very enlightening.Nobody would be better qualified to lead such a discussion than Adrian Arnold. His paper, though short, was a convincing demonstration of the advisability of including the civil engineers in the discussion at a very early stage in the evaluation of new projects. He focused on upgrades for accommodation of bigger or more vessels and for improving productivity.
There were other good papers, some dealing with the “hot” subject of environmentally acceptable anti-fouling bottom paints, some with project management, and one excellent guideline to HVAC system maintenance.
