Time for offshore wind to wake up to full benefits of digitalisation

The following article is a guest post by Jonas Corné, CEO at Greenbyte, a provider of asset management solutions. The article examines digitalisation in the offshore wind sector, the necessity of it and current challenges that hinder using digitalised solutions to advance offshore wind projects.

Despite the global disruption caused by the COVID pandemic, 2020 was a springboard for global offshore wind development. In Europe, the European Commission’s ‘offshore renewable energy strategy’ targeted a 25-fold expansion of its offshore wind capacity by 2050, committing to significant investment in ports, grid connections and the wider supply chain to effectively support the sector’s growth.

However, there is one key area in the EU’s offshore strategy that, despite being crucial to the scaling up of green energy, is noticeably lacking in detail: digitalisation.

Too often, the development and
implementation of advanced digital infrastructure and artificial intelligence (AI)
has been seen as a ‘nice-to-have’ by the offshore wind sector, which
means that some significant advances have gone under the radar. Indeed, AI algorithms
are now capable of providing more than just a way to reduce operations and
maintenance (O&M) costs, with new technologies able to stabilise central
grids and increase electricity dispatch efficiency already available on the
market.

In spite of its rapid growth, offshore wind has not managed to keep up with innovation in digital technologies, with many European offshore owners continuing to rely on outdated in-house data management systems.

This lack of understanding
around digitalisation’s potential benefits is also reflected at a company
level. In a 2019 ORE Catapult survey, 94% of respondents agreed that the
offshore wind industry was not extracting the full value of data and digital
technologies as effectively as it could. In spite of its rapid growth, offshore
wind has not managed to keep up with innovation in digital technologies, with many
European offshore owners continuing to rely on outdated in-house data management
systems.

Investment in legacy
software is better than no digital investment at all, but it leaves offshore
wind owners and operators at risk of missing out on the additional benefits
which more sophisticated asset management systems can provide, on top of simply
minimising O&M costs.

The question is, what is
the actual state of play for digitalisation in the offshore wind sector today
and what steps do owners and operators need to take to make gains?

As discussed earlier,
reducing O&M costs is not the only benefit of offshore wind digitalisation that
needs to be taken into consideration, but it is more pertinent in the offshore
sector than other renewables as losses are often considerably higher. Hiring vessels to transport technicians to
offshore wind sites and carry out O&M can cost tens of thousands, and
that’s without taking into account the revenue lost due to asset downtime.

Operators
can avoid unnecessary site visits by capitalising on software
platforms that can monitor asset performance remotely and provide accurate data
into the performance of individual turbines. Advanced asset management systems can
identify when damage occurs and in which turbine, enabling operators to calculate
when a site visit is cost-effective. For example, Greenbyte’s Predict system
has enabled Dutch utility Eneco to identify major component failures in
their very early stages and take advantage of predictive
maintenance approaches to minimise more costly ad-hoc O&M activities.

As the offshore wind market
has matured, it has also diversified into new technologies. Diversified
portfolios and offshore wind farms developed in chronologically different
phases now often contain turbines from multiple original equipment manufacturers
(OEMs), each of which provide their own performance monitoring systems unique
to their technology. As a result, gathering project or portfolio-wide data into
a comparable format to set performance benchmarks can be difficult.

Technology-agnostic performance
monitoring platforms which can gather and harmonise performance data into a
single comparable format are critical to resolving this, enabling operators to optimise
project-wide performance and identify when they are not meeting expected
electricity production. By investing in such platforms, offshore wind project
owners can also increase their independence from OEMs and hold them accountable
for the performance of their turbines.

Demonstrating that offshore
wind projects are operating optimally will also play an important role in
generating investor confidence and unlocking the additional investment that is
required to hit the EU’s targets. And we have consequently seen increased
appetite from offshore wind operators for user-friendly asset management software
that can provide transparency and improve decision-making.

The same trend can be found
amongst investors too, with drivers such as business case uncertainty, price
risk and growing complexity necessitating greater access to data. Implementing
performance monitoring systems which can identify and mitigate the reason for
sub-optimal asset performance – as well as integrate forecasting and
electricity price data – can help satisfy this demand and inform investor
decision-making. On top of this, greater data transparency can incentivise the
performance of on-site contractors, OEM’s and other parties, further raising
quality standards to generate investor trust.

Another way in which the
offshore sector can improve data transparency is through collaboration with
offshore energy support vessel operators. Site visits are ultimately
unavoidable on any offshore wind project, and CTVs, SOVs and other vessels play
an essential role in their O&M. However, many offshore wind owners and
operators do not consider vessel data in their asset management and performance
monitoring analysis, despite the fact that they remain one of their most
important contractors.

With tech-savvy oil and gas majors continuing to enter the market, offshore wind owners cannot afford to overlook the improvements that can be made today and need to step up investment into their digital infrastructure.

Vessel operational and
performance data such as fuel consumption and ‘time-on-turbine’ is increasingly
required in order to satisfy investors looking to optimise the productivity of
projects and minimise their carbon footprint. Data sharing initiatives such as
‘p-plot’ have provided a strong model for improving transparency between
support vessel and wind farm owners. While it isn’t yet standard practice to
bring all of this data into a single platform, this could yield significant
efficiency gains, including reduced fuel costs and transit times for
technicians.

As the European Commission
rightly pointed out, digital systems should be a key enabler of offshore wind
growth. But that recognition needs to be developed and translated into action
to ensure that targets can be met, for example by integrating offshore wind
into the energy system and improving the sector’s efficiency. With tech-savvy
oil and gas majors continuing to enter the market, offshore wind owners cannot
afford to overlook the improvements that can be made today and need to step up
investment into their digital infrastructure.
