发展海洋顶推运输的新思维——微型无人推船推驳船队

New considerations on the development of deep sea push-barge shipping-minitype unmanned pusher-barge unit

现有海洋顶推运输的优点是造价低 ,在经济航距以内其运输成本也低 ;缺点是联结力大、阻力大 ,因而经济航距受到限制 ,缩小了其适用范围。在分析了海洋顶推运输优缺点及其成因的基础上 ,找出发扬优点、抑制缺点以致消除缺点的途径——使推船微型化 :将居住和驾驶处所由推船移至驳船 ,进而使推船形体微型化。微型推船将有效减小推驳船队的联结力、阻力和造价 ,而整体联结的微推船队则将这些优点推向极点。后者既是极优的推驳船队 。

Modern deep sea push barge shipping has the advantages of lower initial cost and lower running cost within economical navigation distance. But its application is also limited by its disadvantages of larger coupling force and larger resistance which give limitation to its economical operation distance. Based on the analysis to above factors and their causes, the paper proposes a way of utilizing its advantages and eliminating disadvantages, i.e. to make pusher-barge minisized. By moving the living quarter and wheelhouse from pusher to barge, the pusher can be made smaller. Such a unit has the advantages of lower coupling force, lower resistance and lower building cost. A well integrated minisized pusher-barge fleet will bring the advantages of this type of shipping means to optimum.
