DEME vs Van Oord: Offshore Wind Vessel Showdown
The global push toward clean energy is transforming our oceans. Offshore wind farms, once ambitious ideas, are now massive realities powering millions of homes. At the center of this green revolution are specialized offshore wind vessels—gigantic ships burrowing foundations into the seabed, installing turbines taller than skyscrapers, and stringing cables beneath the waves. Two names dominate this niche, high-tech maritime world: DEME and Van Oord.
These aren’t just rivals. They’re innovators driving the future of sustainable energy right from the decks of their engineering marvels. As of 2024, both companies are investing heavily in new-generation offshore wind vessels. Their race to dominate offshore wind installations has caught attention far beyond the shipping and energy communities.
So today, let’s dive deep into the capabilities and missions of DEME and Van Oord, explore their latest vessels, and find out who is steering stronger in this high-stakes game.
The Competition Heats Up
Both DEME, based in Belgium, and Van Oord, headquartered in the Netherlands, have long been giants in dredging and offshore construction. But the real battle has moved into offshore renewable energy, especially the installation of wind farms across Europe, Asia, and now expanding to the US.
Why is this happening now? Because global ambitions for green energy need serious hardware. The new generation of turbines is bigger and heavier than ever, requiring an entirely new fleet of vessels. And in that arena, DEME and Van Oord are leading with state-of-the-art solutions.
According to recent Google Trends activity, the names DEME and Van Oord have surged in searches following key announcements made in early 2024. These include major contracts for offshore wind farm developments in the North Sea and Asia-Pacific along with vessel upgrades and launches.
Meet the Flagships
To understand the strengths of each company, we need to examine their latest hardware—specifically, their offshore installation vessels (OIVs). These ships do the heavy lifting, literally.
DEME’s “Orion” and “Sea Installer”
In DEME’s corner, we have the Orion—a next-generation OIV commissioned in 2022 that’s taken the industry by storm. Built at COSCO Shipyard in China, Orion is 216 meters long and can handle the world’s largest wind turbine components.
Orion’s key highlights:
- Crane lifting capacity of 5,000 tons
- Powered by dual-fuel engines, including LNG—leading in vessel sustainability
- Capable of installing structures in water depths over 60 meters
This ship is pivotal in projects like the Dogger Bank Wind Farm (UK), set to be the world’s largest offshore wind project. The Dogger Bank project alone will have 3.6 gigawatts of power capacity.
Additionally, DEME refitted the Sea Installer (previously owned by A2SEA but now under DEME) to extend its lifespan and enhance lifting capabilities. This proactive vessel management strategy shows DEME’s commitment to staying ahead of demand.
Van Oord’s “Aeolus” and Next-Gen Giant “Les Alizés”
Van Oord’s answer to Orion is the upgraded Aeolus and its ambitious new vessel, Les Alizés, which entered commercial operations in late 2023.
Les Alizés highlights:
- Designed specifically for heavier foundations and XXL turbines
- Lifting capacity of 5,000 tons with a mega crane spanning 150 meters
- Fully electric crane control system reducing fuel consumption
Les Alizés is not a jack-up vessel, meaning it doesn’t require legs to stabilize itself on the seabed. Instead, it installs components while staying afloat—a significant feature allowing quicker setup and improved efficiency in deep waters.
Aeolus, meanwhile, has proven itself on numerous North Sea projects. In late 2023, Van Oord announced it had secured a €500 million contract for wind farm installation in Taiwan—further expanding its crown internationally.
Sustainability as a Core Design Factor
While both companies race to build bigger, they’re also designing for a sustainable future. The maritime industry faces increasing pressure to decarbonize, and both DEME and Van Oord are answering the call.
DEME’s Orion sets the standard with cleaner dual-fuel operations and advanced emissions controls. The ship integrates smart energy management systems to reduce its carbon footprint during operations.
Van Oord’s Les Alizés takes a clever approach by eliminating the jack-up process altogether—saving energy and time. It’s built to comply with EU Stage V emissions limits and aims to become the standard for future OIVs.
Beyond the Vessels: Project Pipeline in 2024
Infrastructure is one thing, but ongoing projects show who’s leading operationally.
DEME’s major engagements (2024):
- Dogger Bank (UK) – largest offshore project globally
- ReefBreather innovation project for underwater wind foundation breathing technology
- Borssele 1 & 2 wind farms (Netherlands)
Van Oord’s big contracts (2024):
- Greater Changhua Wind Farm (Taiwan)
- Saint-Brieuc Wind Farm (France)
- Hollandse Kust Noord (Netherlands)
Both companies are actively working with global developers like Ørsted, Vattenfall, and RWE to deliver projects efficiently and sustainably.
Comparing Technology and Operational Approach
Here’s a breakdown that compares the two companies’ current OIVs in 2024:
| Feature | DEME (Orion) | Van Oord (Les Alizés) |
|---|---|---|
| Max Lifting Capacity | 5,000 tons | 5,000 tons |
| Sustainability Tech | Dual-fuel (LNG) | Fully electric crane & hybrid engines |
| Self-Elevating | Yes (jack-up) | No (floating) |
| First Major Deployment | Dogger Bank | Changhua (Taiwan) |
| Sleeper Projects | Innovative foundation tech (ReefBreather) | Floating wind trials in Norway |
Both vessels are evenly matched in lifting capacity but differ in operational design. DEME bets on traditional jack-up platforms with green fuels. Van Oord leans into floating solutions and advanced electrification.
The Bigger Picture: Global Wind Energy Market
The offshore wind market is growing fast. According to the Global Wind Energy Council (GWEC), the world added over 8 GW of offshore wind capacity in 2023, and 2024 is set to surpass that. Markets like the US, China, and Southeast Asia are picking up speed.
That means demand for experienced contractors and advanced vessels will surge. China alone plans to boost its offshore installations by 15 GW by 2025. The US is targeting 30 GW offshore capacity by 2030. Companies like DEME and Van Oord are positioning to grab a big slice of this action.
Markets outside Europe now require deeper-water installations, heavier turbines, and faster rollout schedules. It’s here that vessels like Orion and Les Alizés will prove critical.
What the Data Says
Google Trends shows rising search interest in “DEME offshore wind,” “Van Oord vessel,” and related terms over Q1 2024. Interest spikes tie into major press releases, contract announcements, and ship deployments.
A snapshot from Google Trends comparing interest between “DEME” and “Van Oord” over the past 90 days shows:
| Day | DEME | Van Oord |
|---|---|---|
| March 1, 2024 | 48 | 32 |
| March 14, 2024 | 74 | 58 |
| April 5, 2024 | 91 | 77 |
Both are on an upward trend, but DEME appears slightly ahead in public interest, likely due to its high-visibility project at Dogger Bank.
Who’s Leading – For Now?
If you’re scoring based on cutting-edge tech, global spread, and sustainability integration, both DEME and Van Oord shine. But their strategies differ—and your winner may depend on what you value more:
- Go with DEME if you prioritize LNG-fueled efficiency and proven track records at world-record scale sites.
- Choose Van Oord if you admire next-gen floating tech and advanced electrification for future-proof installs.
While DEME slightly leads in visibility and scale, Van Oord is innovating quickly and winning major contracts outside Europe.
