HIMAP retrofit programs are managed directly by Stucke Elektronik GmbH (HQ Hamburg). Technical inquiries, migration plans and quotations go exclusively to support@stuckegroup.de.
HIMAP relays were built into thousands of vessels and substations between the late 1990s
and 2016. They served their purpose well — but they are now end of life. Finding
spare parts is hard, finding engineers who know the firmware is harder, and modern cyber
security and communication standards have moved on.
The traditional retrofit answer is invasive: cut the panel, rewire the CT/VT, re-engineer the protection coordination, and book a long docking window. Owners postpone it, and the fleet keeps running on aging hardware until something fails.
SYMAP® R changes that calculation. It is engineered as a 1:1 plug-in replacement for HIMAP — same connector layout, same panel cutout, same wiring. Slide out the old, slide in the new. Parameter settings can be transferred from the former device. The whole job fits in a single docking window or even a port call.

For legacy generations SYNPOL, DICON and SYNPOL D we offer equivalent retrofit programs. Send the installed base list with variants and quantities.
Note: SYMAP® R and the legacy retrofit programs are managed exclusively from HQ Hamburg. Contact: support@stuckegroup.de.
SYMAP® R follows the identical mechanical footprint of HIMAP — same panel cut-out, same connector layout, same wiring. Operations crew gets a modern graphical HMI, single-line representation and status LEDs — without any cabinet work.
Installed between the 1990s and 2016 on thousands of vessels and in industrial substations.
Plug-in
Identical mechanical footprint, graphical LCD with single-line view, modern microprocessors and communications.
SYMAP® R fits the same rectangular cut-out as HIMAP, with identical mechanical mounting and connectors. The polycarbonate cover protects the front panel from mechanical damage during service and while the cabinet is open.
No panel cutting, no rewiring, no protection re-engineering. Slide-in compartment matches HIMAP exactly.
Replacement time per unit is minutes, not hours. No need to extend an out-of-service window.
Three powerful microprocessors, full set of protection functions for generators, motors, transformers, feeders.
Built on the same SYMAP® platform that carries IACS UR E27 cyber security type approval.
Wide range of protocols: Modbus, IEC 60870.
Full lifecycle support from our global service network. Made in Germany — same engineering team that designed your original HIMAP.
Existing protection settings, timing, interlocking and communication parameters from the HIMAP relay are transferred to SYMAP® R through engineering conversion, so the plant behaves identically after the retrofit.
Type approvals from LR, ABS, DNV, BV, CCS, PRS, NK, RINA and KR are not put at risk — SYMAP® R carries the same approvals as the classic SYMAP series on new builds.
Send us your installed base details — vessel list, HIMAP variants and quantities, docking schedule. We will return a unit-by-unit migration plan with timing for each docking window.
SYMAP®R is a retrofit solution supplied and configured exclusively from the Head Office of stuckeGROUP, Hamburg. Each retrofit requires verification of compatibility with the original HIMAP device and the existing wiring, which is performed by the service and engineering team in Hamburg.
HIMAP device type, operating diagram, parameter file (if available), vessel type and IMO number, photographs of the existing installation.
The Hamburg service team verifies SYMAP®R variant compatibility with your configuration and existing wiring.
The exact part number of the SYMAP®R retrofit module is generated according to the confirmed original HIMAP configuration.
A formal quotation is issued from Hamburg with delivery time, commissioning plan and technical documentation.
Typical lead time:5 WORKING DAYS from a complete inquiry with HIMAP device identification.
