China's success in building the world's largest floating crane: 140,000-ton is a miracle-lift ships, cargo-IT information

On May 13, Zhenhua heavy industry independent construction of the world's largest 12000 tons lifting ship for delivery in Shanghai Changxing island base, and in the field named "Zhenhua 30th".

The successful delivery of the vessel to further consolidate the Zhenhua heavy industry in the area of giant floating crane, for salvage and rescue career extending to the sea to provide equipment support.

Project Manager Leng Xijia introduced the floating crane with self-propelled abilities, with DP2 dynamic positioning function, compared with common crane, cost-saving tug and towing time, job actions more precise and comfortable.

The ships also are equipped with 12 thrusters, and meet dynamic positioning function, including 2 2,750-kilowatt thrust, 6 3,800-kilowatt retractable rotating propeller and 4 3,250-kilowatt podded propellers.

In addition, the ship also reserved the 2 propeller, installed in 2017 Zhenhua heavy industry developed the 3,800-kilowatt propeller.

Reporters saw on the ship, giant red hanging beam is 12000 ton floating crane main character. Shanghai salvage Bureau to Zhenhua heavy industry "made to measure" the lifting beam, by Zhenhua heavy industry marine engineering design, steel structures Division built to ensure fishing operations to maximize without prejudice to the sinking ship.

Hanging above the beam by fiber rope connected to the hooks and the 12000-ton floating crane, lifting beams are connected by steel wire rope and the hull below, resulting in fishing operation formed when transitional protection, ensure the integrity of shipwrecks from the water, minimal damage from strength.

2014 Korea "," passenger liner sinking shocked the world. Last year China Shanghai salvage Bureau of the Ministry of transport to "steel backing," the humanization of salvage programmes, with Korea underwater engineering company consortium through layers of selection on August 4 and Korea signed the Department of marine fisheries "," salvage contract.

Last year's salvage team has finished a pilot early and oil pumping operation salvage work. Shanghai salvage Bureau was introduced, to be "more" total lifting, you need at least 10,000 tons of lifting capacity of the crane ship. Crane ship on such a scale in the country at that time very few, there is little international. Shanghai salvage Bureau at that time had contact with Zhenhua heavy industry and other businesses.

The industry, the crane ship Zhenhua heavy industry to deliver 12000 tons, lifting capacity enough to carry on fishing "," sinking of the level of tasks.

In order to ensure this crane delivered to the Shanghai salvage Bureau, Zhenhua heavy industry to include the company's "0th".

12000 tons floating crane trial across the whole spring festival, due to the weight of the boat was about 140,000 tons, draft, crossed the Yangtze into the East China sea trials , means the South channel, Ford effects round about tides of up to 15 days , the project team continuous days of uninterrupted trials jobs, tide stage the successful return of the final drive at the end of February.

Crane is a water lifting project ship, also known as floating cranes, floating cranes, heavy lifting, is widely used in the sea maritime salvation and salvaging, bridge construction and port construction and other fields.

Zhenhua heavy work began in 2000, "testing the waters" since 600 tons floating crane, after 16 years of development, product maturity.

As of now, Zhenhua heavy industry has delivered 32 crane ship, including 9 lifting and pipelaying boat set functions in one, the products are exported to the United States and the United Kingdom, and Korea, and Spain, and Singapore and other 9 countries, access to a market of wide acclaim.

At present, Zhenhua heavy industry construction of 2 lifting ship, tonnage of 5000 and 4500 tonnes respectively.

中国成功打造世界最大起重船：重14万吨堪称奇迹 - 起重船,货船 - IT资讯

5月13日，振华重工自主建造的世界最大12000吨起重船在上海长兴岛基地交付，并在现场命名为“振华30号”。

该船的成功交付进一步巩固了振华重工在巨型起重船领域的地位，为我国打捞救助事业向深海延伸提供了装备支撑。

项目经理冷喜嘉介绍，该起重船具备自航能力，带DP2动力定位功能，与普通起重船相比，节约了拖轮费用和拖航时间，作业行动更加精准自如。

该船还安装了12个推进器，满足动力定位功能，包括2个2750千瓦的侧推、6个3800千瓦的可伸缩式全回转推进器以及4个3250千瓦吊舱式推进器。

此外，该船还预留了2个推进器位置，将于2017年安装振华重工自主研发的3800千瓦推进器。

记者在这艘船上看到，巨大的红色吊梁是12000吨起重船最大特征。上海打捞局向振华重工“量身定制”了吊梁,由振华重工海工院自主设计、钢结构事业部建造，确保打捞作业时，最大限度地不损害沉船船体。

吊梁上方通过纤维绳与12000吨起重船的钩头相连，吊梁下方通过钢丝绳与船体相连，从而在打捞作业时形成过渡保护段，确保沉船出水的完整性，最大限度避免强度带来的损坏。

2014年韩国“世越号”客轮沉没震惊世界。去年中国交通运输部上海打捞局以“钢梁托底”的人性化打捞方案，与韩国水下工程公司组成企业联合体，经过层层遴选，于8月4日和韩国海洋水产部签署了“世越号”打捞合同。

去年打捞团队已经完成预调查和抽油作业等打捞前期工作。上海打捞局曾介绍，要将“世越号”整体吊起，需要至少有一万吨的起重能力的起重船。当时如此规模的起重船在国内很少，国际上也寥寥无几。当时上海打捞局曾与振华重工等企业进行接触。

业内人士介绍，此次振华重工交付的12000吨起重船，起重能力上足以承担打捞“世越号”级别沉船的任务。

为了保证这条起重船及时向上海打捞局交付，振华重工将该项目列入公司的“零号工程”。

12000吨起重船的试航横跨了整个春节，由于该船总重约14万吨，吃水大，跨越长江进入东海试航，途径南槽航道，受到浅滩影响，一轮潮水期约为15天，项目组连续多日不间断试航作业，最终赶在2月底的潮水期成功返航。

起重船是一种用于水上起重作业的工程船舶，又称浮吊、浮式起重机，广泛应用于海上大件吊装、海上救助打捞、桥梁工程建设和港口码头施工等多个领域。

振华重工于2000年开始“试水”600吨起重船以来，经过16年的发展，产品逐渐成熟。

截至目前，振华重工已经交付了32条起重船，其中有9条船集起重和铺管功能于一体，产品远销美国、英国、韩国、西班牙、新加坡等9个国家，获得了市场用户的广泛好评。

目前，振华重工在建2条起重船，吨位分别为5000吨和4500吨。
