  Power-to-X (PtX) products constitute a promising solution component in the
defossilisation of hard-to-abate sectors. Where direct electrification is not
possible, they can find application as chemical feedstock, easy to transport
energy carriers and storage. In this contribution, a modular system
architecture for a highly automated operation of an offshore off-grid PtX
production platform consisting of five layers (asset, control, communication,
digital, application) is presented. The assumed advantage of such an off-grid
platform is the good scalability worldwide as well as easy exploitation of
renewable potentials in any location. Using the example of a power-to-methanol
process, a simplified prototype is outlined.
