浅谈2 940 kW多用途拖轮的设计

随着物流量的不断增长以及港口发展与国内外大吨位船舶进出港的实际需要,迫切需要一些功率大且具有供水、供油、拖带、消防等多用途的拖轮投入使用;此外,我国内河与沿海大规模现代化港口的建设、疏浚工程以及海洋开发工程的发展,也急需一批大功率多用途的拖轮及海洋平台供应船参与配套工作。为此,设计了一种尺度适宜、布置合理、设备节能、经济实用、发展前景好的多用途拖轮。文中以某2 940 k W多用途拖轮为例,简要介绍该种船型的概况、设计优化、节能减排以及船东使用回馈等。

Design of 2 940 kW multi-purpose tug

With the increasing logistic quantity and the development of port, as well as the practical arrival and the departure demand for large-tonnage ships, there is an urgent need for the high-power multi-purpose tug with water and oil supply and ifre prooifng system. In addition, for the construction of inland and coastal large-scale modernized port, and the development of dredging and ocean development engineering projects, a group of high-power multi-purpose tugs and offshore supply vessels are urgently required to be involved in the supporting work. A multi-purpose tug is then designed to be characterized of appropriate dimension, reasonable arrangement, energy-saving equipment, economy and practicability with great development prospect. Taking a 2 940 kW multi-purpose tug for example, this study brielfy introduces hull form, design optimization, energy saving, emission reduction and the feedback of ship owners, etc.
