Across more than five decades, stuckeGROUP devices have entered service through every channel of the power-systems supply chain. We work directly with end-users, but most of our volume comes through OEM relationships, EPC contractors, system integrators, and shipyards who specify SYMAP® as a standard component.
Major shipyards in Germany, Korea, China, Japan, Croatia, Italy, Norway, Finland and Romania specify SYMAP® for new builds. Reasons: full set of class approvals, IACS UR E27 cyber security, single supplier for all bay positions.
Container lines, tanker owners, ferry operators, cruise lines — for retrofit programs and after-sales support across their fleets. Standard installed base means standard service procedures across all vessels.
Drilling contractors, FPSO operators, offshore wind installation companies, dive support & ROV operators — for DP-class installations where electrical reliability is non-negotiable.
Switchboard manufacturers in Europe and Asia integrate SYMAP® as their standard protection bay controller. We provide engineering documentation, type tests and IEC 61850 SCD support for OEM relationships.
Engineering, procurement and construction companies for renewable energy plants, power stations and industrial substations — SYMAP® Compact+ GC fits seamlessly into VDE/G99 grid-connection projects.
Developers and operators of wind farms, solar parks, biogas plants, hydropower stations and BESS installations — for grid connection that the local DSO will accept on first inspection.
Naval auxiliaries, coast guard, patrol vessels — ruggedized installations with hardened communications and shock-tested hardware.
Process industries (refineries, chemical, paper, mining), data centers, hospitals — for emergency power, cogeneration, and critical-load distribution where downtime carries large costs.
For specialized grid-edge applications — small substations, transformer stations, distribution feeders — where the protection device also needs to provide control and communication.

More than 4,300 vessels with HIMAP or SYMAP® devices installed. Container ships, LNG/LPG tankers, chemical and oil tankers, bulk carriers, RoRo and cruise vessels. Offshore platforms, FPSOs, jack-ups and semi-submersibles.
Typical projects: Newbuilds (BCG/ECG for PMS), retrofit during docking (SYMAP R as HIMAP replacement), switchgear modernisation (ARC).
Small and medium hydropower plants, grid-connected diesel gensets, biogas and CHP installations, industrial diesel backup. SYMAP® with the FGH certificate (VDE-AR-N 4110/4120) is accepted by DSO operators in Germany, Austria, Switzerland and across the region.
Typical projects: Single-generator units (Compact+ GC), multi-gen plants (BCG/ECG), cogeneration with parallel grid operation.
Utility-scale solar plants, commercial PV systems, onshore and offshore wind farms, hybrid installations. Compact+ GC carries the full FGH certificate for grid-code applications — NA protection, EZA controller, Q/P regulation per operator requirements.
Typical projects: Grid connection per VDE-AR-N 4110/4120, UK G99, plant controller for parks with multiple inverters, island mode operation.
Process industries — refineries, chemical plants, steel mills, pulp & paper, mining, water utilities. SYMAP® Compact+ and classic Y/BC variants serve motor bays (pumps, fans, compressors), feeder bays and transformer bays.
Typical projects: Motor protection with thermal model, DCS/SCADA integration, ATEX classification of explosion zones, arc-flash protection of MV bays.
Distribution and industrial substations, MV and LV feeders, connection stations, urban substations. Regional DSO operators in SE Europe and beyond standardise on SYMAP® for switchgear protection and control.
Typical projects: Selectivity, earth-fault and directional protection, IEC 61850 Ed. 2 / IEC 60870-5-104 SCADA, retrofit of legacy switchgear.
Battery energy storage for peak shaving, frequency regulation and grid stabilisation. Data centres with N+1 and N+N redundancy. SYMAP® provides a signal interface to the BMS — it is not a BMS replacement, nor a UPS controller.
Typical projects: Compact+ GC for AC grid connection (FGH certificate), Y-BAT for DC battery-side monitoring, BCG/ECG for multi-gen backup in data centres.
For project-specific references — send a request with NDA to contact-tender and we deliver a customer list by industry and region.
Many of our customers operate under confidentiality requirements that prevent us from publishing project names. For tender purposes, we can provide customer-specific reference lists under NDA — including project size, vessel/plant type, scope of supply, and successful FAT/SAT/sea-trial outcomes.
