HarshMoP: Continuous monitoring system on multi-purpose offshore platforms for early detection of corrosion combined with corrosion protection systems.

The project consists of the design of a monitoring system combining corrosion monitoring with turbine monitoring and integrating data from the physical and chemical parameters of the sea and meteocean data. In addition, the complete monitoring system is complemented by the design of a protection system based on new coatings in order to improve the corrosion protection of the structure. The monitoring system allows us on the one hand to estimate more accurately the state and degradation of the material of the floating platform structure and on the other hand to make an in-depth analysis of the protection offered by the new coatings in service.

The HarshMoP solution (monitoring system plus protection system) must be able to be used on different types of floating platforms and mainly for different applications. It must be taken into account that the corrosion phenomenon can be different depending on the use of the platform. The project must achieve on the one hand to reduce the high costs of maintenance manoeuvres on offshore platforms and on the other hand to automate these manoeuvres in a more efficient way in order to reduce the number of inspections and thus the number of trips to the platform, even reducing possible accidents and CO2 emissions.

Nowadays, the structural monitoring systems deployed are usually based mainly on the measurement of the loads and vibrations of the structures without taking into account the degradation caused by corrosion in the different zones (submerged, splash and atmospheric), especially when it comes to offshore platforms installed in the sea where corrosion plays an important role. On the other hand, advances are required in the design of current protection systems that are not capable of slowing down the degradation caused by corrosion in the most critical areas, such as the splash zone.

This project is part of the Climate, Energy and Mobility theme identified within the public-private collaboration programme with the aim of improving the operation and maintenance of offshore platforms by automating maintenance interventions and thus reducing costs and risks. In addition, the aim is to increase the useful life of these structures and also reduce the number and duration of inspections, with the aim of increasing the production of renewable energies and reducing greenhouse gases, as included in the State Technology Sub-programme.
