【摘要】：2011年6月,国务院批准设立浙江舟山群岛新区,将新区功能定位为浙江海洋经济发展的先导区、海洋综合开发试验区、长三角经济发展的重要增长极。舟山群岛新区处于我国南北海运大通道和长江黄金水道交汇地带,是江海联运的重要枢纽,是我国伸入环太平洋经济圈的前沿地区,也是我国扩大开放、通联世界的战略门户。舟山群岛新区深水岸线资源丰富,建港条件十分优越,适宜开发建港的深水岸线总长280公里,船舶避风和锚地条件良好,多条国际航道穿境而过。舟山市是我国重要的船舶工业基地,全市共有造船企业约100家,其中规模以上有46家,以民营企业为主。然而,由于舟山港地理位置特殊,舟山沿海受台风影响较大。2005年“麦莎”台风影响造成锚泊于马峙锚地的扬帆集团3艘新建无动力集装箱船走锚碰撞事件。2012年“海葵”台风在宁波象山登陆,六横岛中远船务工程公司一艘原本系固在码头的57000吨无动力散货船受台风影响断缆走锚后漂移到宁波梅山。之后舟山市政府陆续出台了一系列措施,包括无动力船舶不得到公共锚地抛锚避风,以免发生锚链缠绕和碰撞事故。近年来,舟山港新建船舶呈现逐年大型化的发展趋势,且以建造散货船类型为主,该类船舶受风面积大,船舶防台方法稍有不当,易出现碰撞、搁浅和触礁等危害性事故,因此本文定义5万吨级载重吨以上船舶为大型船舶,开展码头防台安全研究。本文通过收集舟山港大型造船企业相关资料,分析大型舾装码头所处的地理位置、自然条件,结合影响舟山港水域的台风基本特点,根据可能同时出现的风和水流,选择具有代表性的7万吨级、10万吨级、15万吨级散货船,按《港口工程荷载规范》(JTS-144-1-2010)进行系泊受力分析,计算出在不同风、流共同作用下,船舶的系缆力和挤靠力标准值。再根据各造船企业的缆桩布置、缆绳配置情况,对台风天气下新建大型无动力船舶系泊码头防台安全进行研究,为舟山港新建大型无动力船舶码头系泊防台提供比较科学的参考。
[Abstract]:In June 2011, the State Council approved the establishment of Zhoushan Archipelago New area in Zhejiang Province. The function of the new area was defined as the leading area for the development of Zhejiang's marine economy, the experimental area for comprehensive marine development and the important growth pole for the economic development of the Yangtze River Delta. The new Zhoushan archipelagic area is located in the intersection zone of the major shipping channels of China's north and south and the golden waterway of the Yangtze River. It is an important hub of combined transport between rivers and seas, the frontier region of our country's entering the Pacific Rim Economic Circle, and the strategic gateway for our country to expand its opening up and connect with the world. The new area of Zhoushan Archipelago is rich in deep-water shoreline resources, and the conditions of port construction are very superior. The total length of deep-water shore line suitable for development and construction is 280 km, the conditions of ship avoiding wind and Anchorage are good, and many international waterways pass through the boundary. Zhoushan City is an important shipbuilding industry base in China. There are about 100 shipbuilding enterprises in Zhoushan city, 46 of which are above scale, mainly private enterprises. However, due to the special geographical location of Zhoushan Port, The coastal area of Zhoushan was greatly affected by the typhoon. In 2005, the impact of Typhoon "Masha" caused the collision of three newly built unpowered container ships anchored in the Anchorage of Maishi. In 2012, the typhoon "sea anemone" made landfall in Xiangshan, Ningbo. A 57000 ton unpowered bulk carrier, originally fastened to a wharf, drifted to Meishan, Ningbo, after anchoring under the influence of the typhoon. After that, the government of Zhoushan city issued a series of measures, including no power ships to anchor and avoid wind and wind in public Anchorage, so as to avoid chain winding and collision. In recent years, the newly built ships in Zhoushan Port have shown a trend of large-scale development year by year, and the type of bulk carriers is the main type. The ships suffer large area of wind, the method of preventing ships against the sea is a little improper, and they are prone to collision, grounding and reef accidents, and so on. Therefore, this paper defines a ship with a capacity of more than 50, 000 tons as a large ship, and carries out a study on the anti-platform safety of the wharf. By collecting the relevant data of large shipbuilding enterprises in Zhoushan Port, this paper analyzes the geographical location and natural conditions of large outfitting wharves, combined with the basic characteristics of typhoons affecting the waters of Zhoushan Port, according to the wind and water flow that may occur simultaneously. In this paper, a representative bulk carrier of 70,000 tons and 100,000 tons is selected to analyze the mooring force according to the Port Engineering load Code (JTS-144-1-2010), and the standard values of the mooring force and the squeezing force of the ship under the combined action of different wind and current are calculated. According to the cable pile arrangement and cable configuration of shipbuilding enterprises, the paper studies the safety of mooring wharf of new large unpowered ships under typhoon weather. It provides a more scientific reference for the construction of large unpowered ship wharf mooring prevention platform in Zhoushan Port.
