Appendix BExplanatory notes aboutterms in WaterlineIntroductionWaterline was started to provide a vehicle for publishing descriptive data and variousproductivity indicators related to waterfront activities. These activities take place inthree main parts of the port terminal:• on the landside of port terminal• at the wharf side of port terminal; and• within the port terminal.The information in Waterline falls under these three broad categories. Theseexplanatory notes briefly describe these activities and the indicators associated withthem. To correctly interpret the information in Waterline the reader should be clearabout the following issues: the scope of coverage of Waterline, the sources of thevarious data items, the measures of output used in Waterline.ScopeWaterline data relates to five mainland major ports in Australia-namely Brisbane,Sydney, Melbourne, Adelaide and Fremantle.Waterline focuses on containerised cargo; and excludes all other cargo types.Waterline includes only fully cellular ships in its calculations. Fully cellular ships aredefined as purpose-built container ships equipped with 40-foot cell guides belowdeck as a minimum, and exclude such vessels if used for mixed cargoes of containersand general cargo.Data sourcesThe measures of port terminal productivity are based on all available data aboutcontainer movements at the five port terminals. Those measures are based on acensus of activities at those port terminals.Data on costs are based on a sample of ships that call at each of the mainland majorports in Australia. The chosen samples are all ships in the 15 000–20 000 GT range andall ships in the 35 000–40 000 GT range. These vessels represent almost 40 per cent ofvessels in the 15 000 to 45 000 GT range, which itself is almost 85 per cent of all shipvisits to these ports in 2005.57
