R. STAHL TRANBERG

What R. STAHL TRANBERG does

R. STAHL TRANBERG is a Norwegian manufacturer of explosion-proof (Ex) electrical equipment, marine navigation and offshore lighting, and aviation helideck lighting systems, operating as a subsidiary of the German R. STAHL Group. The company is organized into three segments: Energy, which produces Ex-certified heating, lighting, and small-power equipment for hazardous-area oil & gas installations; Marine, which supplies searchlights, floodlights, navigation lights, and anti-icing/de-icing systems for commercial vessels and offshore support vessels (OSVs); and Aviation, which delivers CAP437-compliant helideck lighting for offshore platforms and onshore heliports. Its products carry ATEX, IECEx, CAP437, and DNV-GL certifications, and the company holds a documented No. 1 position in the OSV anti-icing/de-icing segment. Core technologies include Ex-protected LED luminaires, halogen-to-LED retrofit platforms (TEF 2650), Ex heating and thermostat systems (TTC2 Smart Thermostat), and a newly launched modular BlueLine Series of LED luminaires; 3D CAD STEP files are published for shipyard and EPC integration.

The business operates a project-based, quote-driven enterprise sales model, with products specified into new-build vessel, offshore platform, and onshore hazardous-area projects where certification lifecycles run into decades. Distribution is global, leveraging the parent group's worldwide Ex network plus direct relationships with Norwegian shipyards, offshore EPC contractors, and aviation operators, with regional agents such as Sonar in Iceland supplementing Nordic coverage. The company reports 59 employees as of end-2023 and is currently modernizing its back office through an ERP implementation initiated in April 2025 and reorganizing its Scandinavian sales structure effective January 1, 2026. No public revenue, ARR, or order book disclosure is provided; sustainability credentials include an EcoVadis Silver 2025 rating.
