The final wind turbine has been installed at the Aberdeen Offshore Wind Farm, located three miles from the Aberdeenshire coast in the North Sea.

The 11-turbine farm, also known as the European Offshore Wind Deployment Centre (EOWDC), will have a total capacity of 93.2MW.

The power plant features nine 8.4MW turbines, and two 8.8MW turbines – the most powerful in the world.

The turbines are set to produce enough energy that the farm could power 70% of Aberdeen’s domestic electricity demand.

The turbines are also anticipated to offset 134,128 tonnes of carbon dioxide per year once power is generated in the summer.

The EOWDC faced legal issues as the President of the United States, Donald Trump, argued the farm would spoil the view of his favourite golf course.

“This is a magnificent offshore engineering fear for a project that involves industry-first technology and innovative approaches to the design and construction,” commented Adam Ezzamel, Project Director at Vattenfall.

“Throughout construction, the project team and our contractors have encountered, tackled and resolved a number of challenges.”

“The erection of the final turbine is a significant milestone, and with the completion of array cable installation, we now move on to the final commissioning phase of the wind farm prior to first power later this summer.”

“One of our 1,800 tonne suction bucket jacket foundation was installed in what we believe is a world record two hours and 40 minutes from the time the installation vessel entered the offshore site until deployment was complete.”

“What makes this even more significant is that the EOWDC is the first offshore wind project to deploy this kind of foundation at commercial scale while its also the first to pair them with the world’s most powerful turbines.”

Trafigura and Yara International explore clean ammonia usage

Commodity trading company Trafigura and Yara International sign MoU to explore developing ammonia as a clean fuel in shipping

Independent commodity trading company Trafigura and Yara International have signed an MoU to explore developing ammonia as a clean fuel in shipping and ammonia fuel infrastructure.

Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050. 

How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.

Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:

  • The supply of clean ammonia by Yara to Trafigura Group companies
  • Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
  • Development of new clean ammonia assets including marine fuel infrastructure and market opportunities

Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.  

There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.

Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.

Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.

Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.

It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
