What is HarshLab?

HarshLab is an advanced floating platform-laboratory for the evaluation of materials and components in real offshore environment.

This unique offshore infrastructure is suitable for testing new materials and solutions against corrosion, ageing and fouling in immersion, splash and atmospheric zones.

1 - Atmospheric Zone
Samples in atmospheric zone are around 1,5m above the sea surface, so depending on the metoceanic conditions they will receive seawater sprays or not. Orientation and inclination of samples are relevant to determine the corrosiveness of each sample position.
2 - Splash Zone
Samples in splash zone are placed less than 1 meter above the sea surface. Since HarshLab is a floating laboratory in open sea, it is not affected by tides and samples are continuously being splashed by waves. Differences can be observed between NW face receiving the direct impact of swells and the rest of exposition sites around the HarshLab.
3 - Immersion Zone
Samples in immersion zone are heavily affected by fouling. During the first testing months, microalgae and larvae start colonizing samples. After a few months, a variety of macroalgae and molluscs creates a new ecosystem that will pilot the resistance of materials exposed here. Again, fouling growth is determined by orientation, observing relevant differences between the immersion exposition zones around the HarshLab.

Why HarshLab?

Energy sector is nowadays facing a clear movement towards the sea. While some subsectors such as oil and gas started with this transformation some decades ago, operating in offshore conditions supposes an enormous challenge to novel renewable energies, such offshore and ocean energies. Corrosion and fouling are two of the main new obstacles in this race to the sea, while heavy mechanical forces accelerate the ageing of offshore infrastructures, the loss of properties, and finally the reduction of their life expectancy.

HarshLab answers the demand of offshore infrastructures devoted to test materials and components prior to their entry in the offshore market was detected.

Managed by Tecnalia, HarshLab is an unique offshore laboratory open to any institution in the world interested in testing their materials or components in real offshore environment.

During his first year out in the sea, corrosion and biofouling phenomena occurring in HarshLab1.0 were characterized, while 10 industrial companies are running their ageing tests on more than 200 probes and components.

With three different exposition zones available (atmospheric, splash and immersion), metocean conditions are 24/7 monitored thanks to nearby meteorological station and oceanographic buoys moored in BiMEP Area.

Field results can be complemented in Tecnalia’s corrosion and characterization laboratories, where additional specific corrosion tests, ageing in climatic chambers or under mechanical solicitation can be performed according to international standards or specific demands.

  • Corrosion analysis, forecasting, assessment, control and monitoring. 
  • Material and coatings testing and characterization (i.e. chemical composition, microstructure, mechanical properties: tensile test, fatigue).
  • Surface properties, i.e.: surface roughness, coating adherence, wettability, hardness, …).
  • Failure analysis in-service performance and residual life
  • Wear and friction characterization.
  • Artificial ageing in climatic chambers

DATA LAB SERVICES

HarshLab is more than a laboratory for the evaluation of materials and components in a real offshore environment.

In the framework of HarshLab a full set of data related to the ongoing trials can be provided to the user (meteorological data, oceanographic data, corrosion data, appearance…). This data set makes possible to obtain suitable conclusions to take decisions about the behaviour of the tested material/component in this harsh environment.

We can provide also valuable correlations between the observed variables, using advanced data analytics techniques.

A real offshore environment

HarshLab1.0 is moored in the Biscay Marine Energy Platform (BiMEP), an experimental sea zone with a total surface area of 5.3 sq km, situated in the Gulf of Biscay, 1,6 nautical miles in front of the village of Armintza (Bizkaia, Spain).

BiMEP area is well communicated with Armintza’s port and under 24 hour surveillance, which allows a quick access to samples under trial while ensuring 100% offshore conditions.

BiMEP is an open sea test site for WEC trials:

  • 13,2 kV – 5 MW subsea export cables.
  • 24/7 surveillance and monitoring.
  • Research and Data Centre (Monitoring and control system)
HarshLab can be easily reached from Armintza’s port with a 10’ boat trip. Although sea conditions limit the access during heaviest swells, access to the platform is open during the whole year.

Testing in HarshLab

Corrosion Tests

Harsh marine environment is ensured, with a CX classification in atmospheric and splash zones, and Im2 in immersion zone. Immersion zone is prone to the formation of biofouling, so it’s a good opportunity to study the influence of biofouling in initial stages of corrosion in materials and how the presence of barnacles and other biofouling species affects the corrosion rate on different materials.

Antifouling Solutions

BiMEP area is especially prone to biofouling growth, so test immersion sites at HL1.0 are suitable for testing experimental antifouling solutions under real offshore conditions.

Ageing Assays

Not only nude and coated metallic surfaces can be tested in our platform, but also other non-metallic materials that need to withstand harsh marine conditions while maintaining their properties (flexibility, aesthetic, etc)

HarshLab allows the evaluation of standardized probes and other components in real offshore environment, in immersion, splash and atmospheric zones (samples in atmospheric zone can be exposed to 45º or 90º)

HarshLab for R&D

HarshLab is open to both private industrial users, and to public funded research projects. In fact, current materials already testing in HarshLab1.0 belongs to both private users and H2020 funded projects.

HarshLab infrastructure will enable to understand how real offshore conditions may hinder lifetime expectancy of components designed to withstand harsh conditions in offshore industry. Some of these conditions can be simulated in the laboratory with different climatic chambers and regular corrosion tests, but others, such initiation of corrosion phenomena caused by fouling, cannot be simulated in the laboratory.

TECNALIA combines both capacities by offering both field offshore tests in HarshLab and traditional laboratory corrosion tests. A fully equipped characterization laboratory completes a unique offer in a single point entry service capable of supporting industry in their marinization process.
