【In-depth Discussion on Modular Installation in HaiChuan】An Analysis of the Development of Modular Services in Petrochemical Projects 【Reposted from the Internet】

II. The Significance and Necessity of Implementing Modular Operations 2.1 Advantages of Modularity in the Implementation of Petrochemical Projects The development and adoption of modular equipment stem mainly from developed countries such as Europe, America, and Japan. The main reasons for this are the high costs associated with on-site manufacturing and installation, the potential for environmental pollution, and susceptibility to weather conditions. Therefore, foreign companies use modular design to carry out manufacturing processes in factories instead of on-site; this approach offers several advantages: 1) For the same type of equipment, modular design results in less space being required, with equipment and instruments being concentrated in one place, which facilitates better management； 2) Labor costs on site are high; they are even higher in Europe, America, and areas with harsh conditions (poor climate or safety conditions). Some countries or regions impose restrictions on the use of foreign labor. By adopting a modular approach, it is possible to make full use of cheaper local labor, thereby reducing labor costs and the need for installers and local workers on site, and further cutting down project costs.

By adopting a modular approach, it is possible to make full use of cheaper local labor, thereby reducing labor costs and the need for installers and local workers on site, and further cutting down project costs.

4) The modules are processed and assembled in the factory, ensuring better assembly precision and project quality； 5) Modularizing various conventional petroleum and chemical plant units requires significant design resources at the beginning, but once a certain scale is reached, it is possible to **reduce the time required for detailed design. 6) The construction period is short, which reduces the time that workers and equipment spend on site and thus minimizes safety risks during project execution.

2.2 Requirements for international projects In the international construction industry, modularization is becoming increasingly popular. There is a shortage of labor force and skilled installation technicians, the cost of labor on site is high, the construction conditions in certain project locations are harsh, the effective construction period in some areas is short (such as in cold or hot regions), and investors in specific areas tend to adopt modular designs in order to reduce the need for labor on site and thus cut costs. Especially in Western countries such as Canada and Australia, due to a shortage of construction labor and high labor costs, coupled with strict labor entry requirements, professional certification standards, and strong local unions, the import of Chinese labor is directly or indirectly hindered; modular design and installation have thus become essential for project construction ；

Based on several years of experience in international market development, project owners are also very interested in modular manufacturing in China, and have put forward clear requirements regarding modularity. Examples include Sunshine, Suncor, and Blackpearl in Canada, Odebrecht in Brazil, Shell in the Netherlands, and the Arrow project in Australia； For these foreign owners, China’s abundant labor supply and relatively low labor costs make module production in China highly attractive.

2.3 The significance of engineering companies advancing modular business: As outlined above, it is clear that there are demands for modularity from clients and projects. Moreover, having the capability to handle modular business is a necessary condition for winning bids and carrying out projects in certain areas; it is also one of the trends toward greater specialization in projects, offering broad market prospects. For engineering companies, there are also the following two aspects of significance.

1) Project innovation and the development of core competitiveness: With the improvement of China’s design capabilities, enhanced manufacturing skills, continuous improvement of transportation infrastructure, and the upgrading of lifting and transportation equipment, the external conditions for modular manufacturing have become largely mature. Due to its obvious advantages, modularity exhibits strong vitality and is developing at a rapid pace; in the long run, its widespread adoption will undoubtedly bring about a revolution in installation projects. If engineering companies can quickly develop integrated business models and capabilities for modular design, manufacturing, and construction, this is likely to become their new core competitive advantage.

2) Modularity is necessary for market expansion. Currently, regions such as Central Asia, North America, South America, and Southeast Asia, which have relatively abundant oil resources, are key markets for global development, including countries like Singapore, Malaysia, Venezuela, Canada, Kazakhstan, and Turkmenistan. In the competitive market, a company’s design and project services are bound to compete with those of its rivals from Europe, the United States, Japan, and South Korea; modular design and the ability to provide various capabilities are among the key competitive advantages that engineering companies need to achieve in order to expand their market presence.

III. Requirements for implementing modular services, existing conditions, and existing gaps 3.1 The main requirements for modular services are: – Physical conditions: premises, equipment, transportation facilities, etc； -Qualification requirements: design qualifications, manufacturing qualifications, etc ； -Human and system conditions: qualified personnel, modular manufacturing and management systems, computer software, etc ； The following is an analysis of the relevant elements separately

3.2 Design 1) Characteristics of modular design The most important technical feature of a module is that it has independent functions and structure； Whether the entire project can be effectively modularized according to certain requirements during the design phase is the cornerstone and key to implementing modular technology. The modular design approach for projects differs from the traditional integrated design and construction method. The design perspective and approach must take into account both the overall functionality of the project and the relative independence of each module. For example, when dividing the project into modules during the initial design phase, it is necessary to fully consider factors such as the lifting capacity at the construction site, the construction capabilities, the feasibility of loading onto ships, the actual capacity of transport vessels, as well as the installation capabilities and methods at the installation site. All these factors have a direct impact on the success of the project.
