HOLME REFITModular Retrofit& Hybrid Power Solutions
Engineering Beyond Expectations.
Connect the automation the vessel already has. Modernise legacy systems without replacing the existing IAS.
Modern automationwithout a full rebuild.
A modular automation package for smaller commercial and coastal vessels. Start with alarm and monitoring, then add process control and power management.
Hybrid power withoutrebuilding the vessel.
A packaged energy storage and DC-grid retrofit kit for ferries and harbour craft, with a defined scope and a predictable installation timeline.
Upgrade the vessel.Keep it working.
Retrofit automation and hybrid power for vessels ten to twenty-five years old — the ships that cannot justify a full IAS replacement.
The problem
A vessel ten to twenty-five years old is still operating on legacy automation — often proprietary, and not something the HOLME platform can reach.
Replacing the integrated automation system outright is an investment those ships cannot justify, so the upgrade never happens.
Development attention goes to newbuilds and large fleet contracts, and the ageing mid-size fleet is left underserved.
At the same time the market for ferry electrification is large and growing rapidly, and it sits in that very fleet.
Three retrofit products for the ships already at sea.
Three hardware and firmware products for the installed base of older mid-size vessels that cannot justify a full IAS replacement: a conversion box for the automation already aboard, a modular package for smaller vessels, and a packaged hybrid power kit.
The three products
REFIT Bridge
A hardware bridge that connects vessels running proprietary or legacy automation to the HOLME platform — without replacing the existing IAS.
REFIT Lite
A faster-to-install automation package for vessels under about 3,000 GT: coastal ferries, fishing boats and smaller offshore support craft.
REFIT Power
A packaged energy storage and DC-grid retrofit kit, productised as a standard SKU for ferry and harbour craft electrification.
Why REFIT
- 01
The existing IAS stays
REFIT Bridge connects to the automation already aboard, so KEEL and PILOT reach the vessel without replacing the existing IAS.
- 02
Modular, not all-or-nothing
Start with alarm and monitoring, then add process control and power management as needed — not one decision taken up front.
- 03
A defined scope, not a bespoke project
Unlike bespoke energy storage projects, REFIT Power is a standard SKU with a defined scope and a predictable installation timeline.
Built for the ships that are already at sea and still earning.
Owners of ageing mid-size vessels — ten to twenty-five years old, still working, still running the automation they were built with. REFIT gives those ships a modernisation path that does not begin by removing the system.
Ferry and harbour craft operators moving toward electrification, where a packaged energy storage and DC-grid kit fits a scheduled service better than a bespoke project does. REFIT Power is a defined scope, not a one-off design.
