EH47高强度厚钢板角焊缝裂纹修补工艺研究

随着造船业飞速发展,大量高厚度、高强度、高韧性的钢板被应用于大型集装箱船的上甲板区域。EH47是工业革新的最新成果,它的屈服强度高,被使用于万箱级集装箱船的上甲板区域。某船厂10000 TEU船舱口围钢板与舾装件角焊缝发生开裂,通过有限元计算出裂纹发生的可能性,并分析了开裂发生的原因,针对结构特点和材料特点,采用CO2气体保护焊焊补,通过选用合理的焊丝、预热温度、焊后保温等措施来防止裂纹的产生。     

原油油船货油舱耐蚀钢检测技术发展研究

货油舱的服役环境复杂,对船板钢具有很强的腐蚀性,内底板主要发生点蚀,上甲板主要发生均匀腐蚀。货油舱使用耐蚀钢是涂层保护的唯一替代方案。国际海事组织和中国船级社对货油舱耐蚀钢的腐蚀检测要求进行了明确规定。内底板耐蚀钢腐蚀检测要求简单,国内研究机构已经熟练掌握,取得了较多的研究成果;上甲板耐蚀钢腐蚀检测要求复杂,国内相关的研究成果较少。设备标准化及参数统一化是上甲板耐蚀钢腐蚀检测技术的发展方向。

双燃料船用发动机废能回收系统的技术经济比较（英文）

Nowadays alternative and innovative energy recovery solutions are adopted on board ships to reduce fuel consumption and harmful emissions. According to this, the present work compares the engine exhaust gas waste heat recovery and hybrid turbocharger technologies, which are used to improve the efficiency of a dual-fuel four-stroke(DF) marine engine. Both solutions aim to satisfy partly or entirely the ship’s electrical and/or thermal loads. For the engine exhaust gas waste heat recovery, two ste...     

港口国监督案例分析

一、基本情况NH轮是1989年建造的3961TEU集装箱班轮,2001年以前入的是船级社A(ICSA成员),后改为船级社B(ICSA成员)。2005年8月18日在实施PSC检查时,检查人员发现该轮干舷甲板的勘划和其出厂时原始《干舷计算书》所核定的干舷甲板位置相差3米。如果按船级社B签发给该船《国际载重线证书》上勘划的甲板线来确定干舷甲板的话,则该轮的上甲板为干舷甲板,则干舷甲板(上甲板)下的二层甲板(艉绞缆机甲板)上的相关舱室开口均无法达到水密关闭要求,因此检查员将该问题判定为缺陷。

Key technology of ship product data exchange based on STEP

In this paper, in order to implement the share and exchange of the ship product data, a new kind of global function model is established. By researching on the development and trend of the application of ship STEP （ standard for the exchange of product model data） standards, the AIM （application interpreted model） of AP216 is developed and improved as an example, aiming at the characteristics and practical engineering of ship industry in our country. The data exchange interfaces are formed based on STEP in the CAD/CAM for the ship by all function modules and shared databases under the global function model. The share and exchange of all information and data are solved in the design, manufacture and all life-cycle of ship products among different computer application systems. The research work makes foundation for the ship industry informatization.     

“风”字号远洋货轮的设计改革

在学习无产阶级专政理论运动的推动下,我厂技术组万吨轮设计小组的同志,联系实际,冲破旧框框,发扬不断革命精神,对“风”字号万吨轮的结构设计,先后进行了三次近40项重大改进。通过在“风展”号轮上实施,证明每艘船可以节约钢材20吨、电缆1000多米、木材120米~3,而且还可节约大量人力,大大改善劳动条件,减轻劳动强度。主要改革有以下几项: 1.上甲板边板与舷侧顶列板的铆钉连接结构,改为直接焊接结构。这一改革共节约了φ28毫米铆钉2600多只、船板12吨,节约装配、钻孔、铆接、捻缝等工种100多人工,还缩短上甲板与船旁板的总装时间一个多星期。
