Group 1 - Japan's net investment in the US for 2024 is projected to reach 11.7 trillion yen, marking a historical high, while investments in China have not increased [1][2] - Japanese companies are accelerating investments in the US, with net foreign direct investment reaching 31.6325 trillion yen, a 17.1% increase from the previous year, the highest since 1996 [2][4] - Japanese investments in ASEAN are also rising significantly, with an estimated 4.4 trillion yen in 2024, a 36% increase from the previous year [4] Group 2 - Japanese investment in China is projected to be only 493.1 billion yen in 2024, remaining stable compared to 2023, and down nearly 60% from ten years ago [4][11] - The depreciation of the yen by 7.8% against the dollar in 2024 has not deterred Japanese companies from increasing foreign investments [6] - Japanese companies are focusing on high-tech investments in the US, with 70% of investments concentrated in AI, biomedicine, and new energy vehicles [10] Group 3 - The US market's appeal is driven by its large consumer base of 330 million people and high per capita consumption, prompting companies like Toyota to invest significantly in the US [9][10] - Japan's investment in the US has increased from 29% in 2014 to 39% in 2024, while investment in China has decreased from 22% to 7% [13] - Japan plans to increase high-tech investments in the US to 8 trillion yen annually by 2030, focusing on quantum computing and space economy [13]

Core Viewpoint - The development of offshore oil and gas field control systems is shifting towards high integration and autonomy, emphasizing the importance of automation in production management [1][3]. Group 1: Offshore Oil and Gas Field Control Systems - Automation control systems are crucial for the production management of offshore oil and gas fields, ensuring safety and efficiency [1]. - The overall control scheme for offshore facilities must prioritize personnel and equipment safety, prevent environmental pollution, and facilitate operational management [1]. - For large-scale platforms, reliable DCS/PLC control systems should be prioritized, integrating various control systems to enhance management and reduce investment [1][2]. Group 2: Control Systems for Small-Scale Platforms - Small unmanned platforms typically have simpler production processes and often utilize PCS and safety instrumented systems (SIS) [2]. - Integrated control systems (ICS) can be employed for small unmanned platforms to streamline architecture while ensuring redundancy and lowering operational costs [2]. - The system must meet specific safety and power supply requirements to maintain critical functions in extreme environments [2]. Group 3: Comparative Analysis of Control Systems - Domestic control system designs focus on overall controllability and redundancy, while international designs prioritize cost-effectiveness and inherent safety [3]. - The Zawtika gas field in Myanmar exemplifies a low-cost, high-reliability approach, sacrificing some asset protection for personnel safety [3]. - The future of offshore oil and gas field control systems will involve overcoming hardware stability challenges in harsh environments and achieving domestic control in key technology areas [3]. Group 4: Future Directions - The industry aims to achieve intelligent upgrades and autonomous breakthroughs to lower lifecycle costs while ensuring safety [3]. - There are two distinct technical routes being explored: process simulation and pipeline simulation, with a need for collaboration between the two [3].
