Inland Waterway & Coastal
Our unique expertise
A Perfect Combination of Marine Standard & Landbase Cost
Approximately 40% of the world’s population lives within 100 km (62 miles) of a coastline. This area often suffers high humidity and high salinity air, sometime even wave erosion. The environment condition is similar as the marine environment.
The inland navigation vessels face lower requirements to ESS onboard but in fact facing acatcly the same design challenges and risk to safety as maritime.
GWT successfully delivered the ES-TRIN comply solution that suitable for inland waterway and costal ESS application, with cost close to landbase product. We pay attention to every details to ensure a reliable ESS which will constantly in operation without the worry from the challenging enviornment.

Mobile ESS container for shore charging at Port
Electricity infrastructure in the ports is currently one of the biggest limitation to the harbor decarbonization. With our innovative design, we can fit up to 5MWh energy per 20ft container and supply energy more efficient and cost-effective.
Our innovative design takes good care of the vibration and impact during transport and ensure a safe operation.
Floating ESS container for shore charging at Port
The electric ship requires high power to charge, this is a challenge to the electricity infrastructure in the ports. A charging station with battery can supply high current and provide enough power to vessels in the port. The battery can be charged slowly overnight.
Integrated with our 10 years of marine design expertise, the container is marine environment resistant and suitable for applications in port for long term.
Marine standard Anti-corrosion Technology
Green Whale Technology specializes in manufacturing costal area used battery containers with advanced Marine Standard Anti-Corrosion Technology, ensuring durability in harsh environments.
Our containers feature high-grade epoxy and polyurethane coatings that meet IMO PSPC and ISO 12944 C5-M standards, providing exceptional seawater and chemical resistance. We use marine-grade steel an alloys, along with hot-dip galvanization (ISO 1461), to enhance structural longevity.
To prevent electrochemical corrosion, we integrate cathodic protection systems. Additionally, all major equipment undergo salt spray testing for long-term performance validation.
By combining these industry-leading anti-corrosion technologies, we deliver reliable, long-lasting marine battery containers that meet the highest international standards, supporting sustainable and efficient power solutions for the maritime industry.
Marine standard Anti-humidity & Ingress Technology
Green Whale Technology designs Costal ESS containers with advanced anti-humidity technology to ensure long-term durability in harsh maritime environments.
Our containers feature IP55 rated enclosures with marine-grade rubber sealed doors and EPDM gaskets, providing superior moisture protection. To further prevent condensation, we integrate dehumidifiers and silica gel packs inside the enclosures.
Continuous seam welding and hermetically sealed battery compartments eliminate gaps that could allow water intrusion.
Every container undergoes ISO 9227 humidity testing, ensuring optimal performance in extreme marine conditions. By implementing these technologies, we provide highly reliable and weatherproof battery containers, safeguarding critical energy storage for offshore and maritime applications.
