Maritime Industry Briefing: Semiconductor Market Growth Signals Broader Technology Demand

## Maritime Industry Briefing *July 29, 2026* While this week's broader technology news cycle has been dominated by semiconductor market data, the underlying trends carry relevance for maritime industry stakeholders investing in vessel automation, electronic navigation systems, and port infrastructure digitisation. ### Silicon Wafer Shipments Rise on AI and Industrial Demand Worldwide silicon wafer shipments increased 7.4% year-on-year in the second quarter of 2026, according to the SEMI Silicon Manufacturers Group (SMG), which released its quarterly industry analysis on July 29. The growth was attributed primarily to surging demand from artificial intelligence applications, with industrial and automotive markets also showing signs of recovery. For the maritime sector, the recovery in industrial and automotive semiconductor supply chains is a positive indicator for vessel electronics, engine management systems, and onboard automation platforms — all of which rely on stable and cost-effective chip supply. The AI-driven demand surge also underpins continued investment in autonomous vessel research and smart port logistics systems. ### GaN Substrate Market on Track to Double by 2032 Separately, a new market report from MarketsandMarkets™ projects the Gallium Nitride (GaN) substrate market will grow from USD 0.62 billion in 2026 to USD 1.25 billion by 2032, representing a compound annual growth rate of 12.5%. GaN technology is increasingly used in high-efficiency power electronics and radio frequency applications. In maritime contexts, GaN-based power devices are gaining traction in shore power systems, high-frequency radar and communications equipment, and the power conversion systems critical to hybrid and fully electric vessel propulsion. As the shipping industry accelerates its decarbonisation agenda, efficient power electronics represent a key enabling technology. ### Industry Takeaway While neither report is maritime-specific, the semiconductor supply chain underpins virtually every aspect of modern vessel operation and port management — from electronic chart display systems and AIS transponders to automated mooring solutions and emission monitoring equipment. Continued growth and stabilisation in global chip markets supports the technology investment cycle that the maritime industry depends upon as it navigates its digital and green transition. *Sources: SEMI Silicon Manufacturers Group (SMG); MarketsandMarkets™*
