Metrology and Marine Power Equipment

ROUNDTABLE - THU SEPT 4 - 09:00 - 10:00

(Roundtable host by National Measurement Data Application Base (Marine Power Equipment), affiliated to Shanghai Marine Equipment Research Institute)

1. From the perspective of global metrology systems (such as OIML and IMEKO), what opportunities and challenges do you believe the digital transformation of metrology presents for supporting the reliability, safety, and performance assessment of marine power equipment?
2. In complex, dynamic, and environmentally demanding applications like marine power equipment, what key adjustments or innovations are needed in the concepts and methods of measurement uncertainty assessment to adapt to the demands of the digital age?
3. Digital twin technology holds enormous potential for simulating and optimizing the operation of marine power equipment. What core role do you believe metrology should play in ensuring a reliable correspondence between digital models and real-world physical behavior?
4. To promote the digitalization of marine power equipment metrology, what key issues need to be prioritized in terms of international standards and collaboration? What are your observations from your perspective as the leader of the relevant international working group?
5. Marine power equipment demands extremely low power consumption, high reliability, and strong anti-interference capabilities from data acquisition systems. What do you believe are the biggest bottlenecks currently facing the hardware layer (sensors, embedded systems, interfaces)? What are the future development trends?
6. Wireless sensor networks and distributed measurement systems hold great promise for application in marine equipment, but they also face environmental, safety, and data processing challenges. What are your thoughts on the maturity and application potential of these technologies in the digitalization of metrology for marine power equipment?
7. As marine power equipment becomes increasingly intelligent, hardware security becomes a fundamental guarantee for the credibility of metrological data. What unique new threats do you believe hardware security faces in the context of digital metrology? Where should the core protection strategies be focused?
8. Your research spans all aspects of the data acquisition chain (front-end hardware, ADC, signal processing). From a holistic system perspective, where do you believe the most critical technological convergence is needed to achieve seamless conversion from physical signals to trusted digital data for marine power equipment?
9. One of the core principles of metrology is traceability. How do you think this traceability can be effectively established and communicated within the massive, multi-source, and sometimes real-time digital data streams generated by marine power equipment? What are the main challenges facing existing methodologies?
10. Measurement uncertainty is a quantitative expression of the confidence level of metrological results. In automated and intelligent marine equipment data processing, what are the main theoretical obstacles and practical engineering challenges facing the automatic assessment and dissemination of measurement uncertainty?
11. You have long been interested in the implementation of the International System of Units (SI) in the digital world. What are the far-reaching implications of this for achieving data interoperability, long-term reusability, and international recognition in the marine power equipment sector? What are the key factors driving this progress?
12. The digitalization of marine power equipment metrology requires robust software tools and infrastructure support (e.g., the GUM Tree Calculator you developed). What core responsibilities do you believe national metrology institutions should assume in providing these fundamental digital metrology services? How should the collaborative model with industry be structured?
