A Comparison of Chinese, Japanese, and Korean shipyard production technology

This paper compares Chinese, Korean, and Japanese shipyard production technology. Development in the world shipbuilding over recent years has influenced focus areas related to shipyard manufacturing technologies and product performance. Software systems, information technology, production technology, and local challenges of shipyards are compared with shipbuilding outputs among these three countries. Various technologies developments, shipyard production and the problems in Chinese, Japanese, and Korean shipyards are discussed respectively. Finally, future areas of research are pointed out.

Green Offshore Structures Promising Viable Utilization of Shipyard Facilities

The shipbuilding industry in Europe is in crisis due to the recent economic recession and competition from countries with low labour costs. Greek shipyards have been forced to make a series of structural changes which have resulted in lower employment levels. Although these changes were gradually creating the conditions for shipyards profitably to re-enter international markets, the current economic crisis and the consequences to the shipping sector have created major problems to the shipyards employment. Perama shiprepair zone, an industrial zone mainly consisted from SMEs （small and medium enterprises） in shipbuilding and shiprepairing sector, has faced major problem for its survivability. In this article, a new approach is presented. Green offshore structures are expected to create competitive advantages in the zone and be a way to utilize available facilities and recover from the existing situation. International experience through case studies is presented followed by economic and technical feasibility for offshore windturbines construction and wave energy devices in shipyards. Finally, a general model shows that sustainable development is possible and shipyards have the adaptability and resources required tbr the production of renewable energy offshore structures.

Shipbuilding—An Analysis from the Perspective of Enterprise Resources Planning System

Designed as a tool for business intelligence, resource planning is used to manage the essentials of a business by integrating processes into a single system. Enterprise Resource Planning (ERP) solutions ensure all the organizational, operational, and procedural structures interconnection, which can be both an advantage and a disadvantage, knowing that inefficiency within one structure will lead to inefficiency in others. The originality of the approach consists in the unitary analysis of all processes which shipbuilding involves (design;evaluation of ship construction possibilities;contracting of works;contracting of supply of materials and equipment;presentation of inspections for the completed works reception;delivery of the ship into operation). The systemic approach is a notable contribution by highlighting the input and output quantities for the analyzed processes. Also, where it was found relevant, the diagrams highlight the owners of the process and show the interconnectivity of the functional departments within a shipyard. Although it is obviously the expression of in-depth knowledge of the peculiarities of Romanian shipyards, the authors hope that the work can support any shipyard that may be interested in knowing these structures (as a logical scheme mandatory to design a custom ERP software system).

“火烧船厂”与政府的救灾活动——以宣统三年吉林省城大火为中心

吉林市在历史上火灾频发,宣统三年(1911年)的大火即是其中较大的一次。在这次火灾中,全城三分之二被烧,房屋被焚5万余间。此次大火给吉林省城带来经济、文化等方面的损失和深远影响以及该城在东北区域内经济地位变化的影响是无法用数字估量的。同时,此次大火的发生,政府扑救不力难辞其咎。不过灾后政府在财力有限的情况下,积极进行多项救灾活动,成效还是比较显著的。

基于Docker云平台的管理系统构建及分析

主要对Docker云平台进行了研究.首先,从容器化、容器技术的发展历史、Docker依赖的技术和Docker的应用场景4个方面阐述了容器技术的基础知识;其次,从Docker的优势、Docker在云计算中的应用现状和Docker给云计算带来的变化等方面论述了云计算与Docker的关系:然后,在Ubuntu上部署了Docker的管理平台,即Shipyard,并在该平台上部署了手写服务;最后,为了验证该平台的可用性和Docker的高性能、低开销的特性,本设计还进行了3个测试实验,即物理机和Docker的性能对比、Docker数量对系统的性能影响和不同平台(物理机、Docker、KVM)的性能对比实验,测试结果和预期相吻合.

Production Balance of Ship Erection

A network plan model of ship erection was established based on the network planning technology and the work-package breakdown system. The load-oriented production control method was introduced to build up a throughput diagram model thus it is possible to describe the ship erection process numerically. Based on the digitalized models some cases of production balance of ship erection were studied and three balance indexes were put forward, they are the load balance rate, the input manpower balance rate and the maximum gantry crane operating times. Such an analytic method based on the balance evaluation is the important foundation for digitization and intelligentization of shipyard production management.

The market logic of LNG carrier boom

As of August 20,38 LNG carriers have been delivered this year(including 4 floating regasification storage units<FSRU>and LNG bunkers<STS>).In addition,25 LNG carriers will be completed and delivered by the end of this year if everything is on schedule.The annual delivery volume is 63,which is roughly equivalent to the release of one LNG carrier every 140 hours.In addition,statistics shows that at present,the number of new orders for LNG carriers is 43,and the delivery volume will reach 43 and 45 respectively in the next two years.From the aspects of delivery volume,completion speed and orders,the shipyards are very busy.

清末吉林地方的官绅矛盾——以宣统三年“火烧船厂”事件为中心

清末随着士绅阶层经济水平的提升、政治诉求的增强,官绅矛盾凸显。宣统三年,吉林省城发生大火,长期的权力争夺和救灾举措不当导致惨重损失,引发了以谘议局为代表的吉林士绅的不满。谘议局就火灾问题向吉林巡抚发出七条质问,巡抚被迫辩护。“火烧船厂”质问事件是清末以来“民权”与“官权”对抗的一个缩影,是清末官绅矛盾中的一个代表性事件,推动了火灾善后工作的有效开展,增强了吉林士绅的政治影响力。
