The Australian National Line's call for world tenders to build two 75,000 tonne d.w. coal-fired steam turbine bulk carriers--and Bulkships Ltd's enquiry for two similar 70,000 tonners--must stimulate other operators to investigate the potential of a cheaper alternative to fuel oil. The intensive studies made by the Australian team in determining the design specification lend special interest to their conclusions. The installation favoured is a mechanical spreader stoker-fired arrangement using lumped rather than pulverised coal which is not considered suitable for the relatively small power plants involved. Other forms of coal firing were analysed but "significant drawbacks" made them less acceptable than the method selected for this particular application. High temperature, high pressure twin boilers have been specified to give virtually total independence from liquid fuels and to provide a reserve of power for emergencies--vital for ships operating for most of the time in restricted waters inside the Barrier Reef and Gulf. The ship design, evolved by ANL, incorporates maximum dimensions of length, breadth and draught to allow them to operate in those waters. Also of interest is a "unique" hold arrangement to facilitate the rapid discharge of bauxite.
