Revenue model

1. Air Lubrication System Sales (Newbuild): Sale of Silverstream Systems for installation on newbuild vessels at shipyards. The company works directly with shipyards, design houses, owners, charterers, and class societies globally from early-stage design through to final delivery.
2. Air Lubrication System Sales (Retrofit): Retrofit installation of Silverstream Systems on in-service vessels, typically completed in 10 days during planned dry dock periods (fastest recorded: 6 days). Some installation work can be carried out at sea by travelling crew.
3. Silverstream Service / Aftercare: Comprehensive aftercare services including Precision Care Agreement (on-time planned maintenance, diagnostic inspections, genuine OEM parts, Silverstream-approved technician services), Global Parts Agreement (fast global access to OEM parts at known pricing), and Fleet-Sync Programme (simplified service for fleet operators with multiple vessels). Services tailored to individual needs ensuring uptime and long-term performance.

Core offering

Silverstream Technologies develops and supplies the Silverstream System, a patented air lubrication technology retrofitted or fitted newbuild onto commercial ship hulls. The system uses compressors, distribution pipework, and hull-mounted Air Release Units to generate a layer of microbubbles that reduces frictional resistance between the hull and seawater, delivering measurable fuel and emissions reductions for vessel operators.

Product overview

Silverstream Technologies offers a single unified product—the Silverstream® System—which is a patented air lubrication technology. The system consists of four key components: the Control and Monitoring System (CMS), Air Compressors, Air Release Units (ARUs), and Air Balancing Module. These components work together to generate a carpet of microbubbles beneath ship hulls, reducing frictional resistance and delivering 5-10% fuel savings. The company complements its core technology with Silverstream® Service, an aftercare programme offering maintenance, parts, and fleet management solutions. The system is available for both retrofits on existing vessels and integration into newbuild projects.
