Bamboo as offshore structural material: China's Jilin-2 platform puts the concept to a real-sea test
A 100-kW floating solar platform built from engineered bamboo composites is now operating off Yantai — and the durability data it generates will matter beyond China.

THE NEWS
According to Marine Insight, China has deployed a 100-kilowatt floating solar platform constructed from engineered bamboo off the coast of Yantai, in Shandong province. The platform, designated Jilin-2, was jointly developed by the CIMC Offshore Engineering Research Institute, China Forestry Group Corporation, and Beijing Forestry University. Its core structural premise is straightforward: replace the steel and high-density polyethylene (HDPE) typically used in floating solar platforms with bamboo-wound pipes and a fibre-reinforced wood-bamboo composite material called "Sea Bamboo Pipe."
Jilin-2 will supply electricity to a demonstration project producing ammonia, hydrogen, and methanol. Developers will monitor the platform's performance against corrosion, high humidity, salt spray, ultraviolet radiation, and long-term fatigue. The platform represents a tenfold scale-up from its predecessor, Jilin-1, a 10-kW prototype launched in 2023. According to Beijing Forestry University professor Qi Chusheng, the bamboo and wood fibres were modified specifically to withstand marine conditions. The development team has stated its intention to scale toward a megawatt-level bamboo-based project.
Yantai CIMC Raffles Ocean Technology Group announced the platform in June. The company indicated that bamboo-based materials could lower the environmental impact of offshore structures relative to conventional steel and HDPE designs. China's broader policy context includes a 2023 national action plan to substitute bamboo for certain plastic products, a goal subsequently incorporated into the country's latest forest and grassland conservation plan.
WHY IT MATTERS
For the Brazilian offshore professional, Jilin-2 sits at an unusual intersection: it is simultaneously a materials science experiment, a renewable energy demonstration, and a signal about where alternative structural thinking is heading in the offshore sector. Its direct operational relevance to Brazilian pre-sal development or FPSO contracting is limited today. But the longer-arc question — whether bio-based composites can perform credibly in persistent marine environments — has implications that extend well beyond floating solar.
The central technical question Jilin-2 is designed to answer is durability under cumulative marine stress. Steel corrodes; HDPE degrades under UV over time and raises end-of-life disposal questions. Bamboo composites, if they can be engineered to resist salt spray, humidity cycling, and fatigue loading over multi-year horizons, would offer a material with a different cost and carbon profile. The platform's monitoring program is explicitly designed to generate that performance dataset. Until that data exists, the concept remains a hypothesis — which is precisely why the Jilin-2 deployment is the appropriate next step rather than a commercial rollout.
For Brazilian offshore renewable energy development — an area receiving growing attention as operators and regulators explore offshore wind and floating solar along the Brazilian coastline — the structural material question is not academic. Brazil's offshore environment presents its own corrosion and biofouling challenges, and any credible alternative to HDPE floats or steel substructures would need to be validated against those specific conditions, not just those off Shandong. The Jilin-2 dataset, if published openly, would provide a useful reference point for Brazilian researchers and developers evaluating bio-composite options.
There is also a supply-chain dimension worth noting. Brazil is one of the world's significant bamboo-producing regions, with native and cultivated species distributed across multiple biomes. A validated offshore application for engineered bamboo composites would create a potential intersection between Brazil's forestry sector and its emerging offshore renewables supply chain — a connection that does not currently exist in any structured way. This is speculative at the current stage of Jilin-2's development, but it is the kind of second-order pathway that materials validation programs can eventually open.
From a regulatory and certification standpoint, any bamboo-composite offshore structure deployed in Brazilian waters would need to navigate ANP oversight and, depending on the application, classification society rules that were not written with bio-based structural materials in mind. The classification societies have been gradually updating their frameworks to accommodate novel materials in marine applications, but bamboo composites in primary structural roles remain outside established rule sets. The data Jilin-2 generates could, over time, inform the technical basis for such frameworks — a process that typically takes years and requires independent validation.
It is worth keeping the scale in perspective. Jilin-2 is a 100-kW platform. Brazil's offshore energy ambitions, and even its smaller nearshore renewable demonstration projects, operate at scales several orders of magnitude larger. The path from a 100-kW bamboo solar platform to a material that meaningfully competes with steel or engineered polymers in offshore structural applications is long and contingent on the durability results. What Jilin-2 represents is the beginning of a credible evidence base, not a near-term market shift.
CONTEXT
Jilin-2 follows a pattern visible in other segments of offshore technology development: small-scale, instrumented demonstrations designed to generate performance data that de-risks larger investments. The offshore wind sector followed a comparable trajectory with floating foundation concepts — tank testing and small pilots preceded commercial-scale deployments by a decade or more. The bamboo composite pathway is at an earlier stage than floating wind was when its first pilot turbines were deployed, but the methodological logic is similar.
China's parallel expansion of conventional offshore solar — including a 1-gigawatt offshore solar farm brought online off Dongying in Shandong, described by its developer as the world's largest — provides context for where Jilin-2 sits within China's broader energy strategy. The bamboo platform is a materials research program running alongside, not instead of, mainstream offshore solar development. That framing is relevant for assessing how seriously to weight its near-term commercial implications.
