New Electric Boat To Banish Emissions From Offshore Wind Sites

The global offshore wind industry has a fossil fuel problem. The kilowatts generated by offshore turbines are clean enough, but the workboats needed to build them typically run on marine gasoil, a high density fuel similar to the heating oil used in buildings. That is beginning to change as the electrification trend hits the shipbuilding industry, so let’s take a look at the 19th century-rooted Liverpool firm Bibby Marine to check out the latest development.

The Falling (And Rising) (And Falling) (And Maybe Rising Again) Cost Of Offshore Wind

The cost of offshore wind had nowhere to go but down throughout the early 2000s, but the industry began encountering some headwinds following the COVID-19 pandemic of 2020 and Russian President Vladimir Putin’s war of choice against Ukraine in 2022. By 2023, the World Economic Forum was raising the alarm over high costs related to supply chain disruptions and labor.

In 2025, US President Donald Trump’s war of choice against offshore wind saddled the industry here in the US with costly delays, though work continues on five offshore farms. Now it’s 2026 and Trump’s misbegotten (to put it mildly) war against Iran has further complicated matters for the offshore wind industry. In a matter of days the attack has already spiraled into a regional conflict, disrupting global energy markets and supply chains alike while  fostering a price spike that will ripple into marine fuels.

In other words, it’s a perfect time for the offshore wind industry to ditch marine fuel in favor of electric CSOVs (Commissioning Service Operational Vessels), particularly if electrification helps to slash the cost of constructing offshore wind farms.

The Bibby Marine Solution

SOVs are purpose-built to install offshore wind turbines as quickly and efficiently as possible, so they play a key role in keeping costs down, including offshore labor costs. Cutting the operational cost of the vessels themselves is a next-level endeavor, and that’s where Bibby Marine comes in.

The company’s solution is a hybrid electric CSOV aimed at reducing operational costs by up to 40%, compared to vessels using marine fuel alone.

“Hybrid-electric eCSOVs use dual fuel generator sets to charge onboard batteries that power the vessel’s main electric propulsion when grid charging is not available,” Bibby explains. “In this configuration, engine load and speed can be optimised to reduce energy consumption, fuel costs and carbon liabilities, saving as much as USD1m per year.”

That’s just for starters. Because the vessels travel relatively short distances, offshore charging stations can enable them to operate exclusively in electric mode. “Where offshore charging is available and fuel consumption and carbon emissions are cut to zero, costs can be reduced by as much as 70%, or an average of USD1.8m savings per year,” Bibby states.

The Electrifying Proof

Bibby makes the full case for eCSOVs in a new whitepaper titled, “The Electrifying Proof.”

“We are seeing that as technology matures, capital costs for electrified vessels are becoming increasingly competitive,” Bibby notes. “On the infrastructure side, shore power is already expanding, and offshore charging systems from leading OEMs can be integrated into wind farm projects launching in the coming years.”

“For operators of these windfarms, fully electrified vessels are especially cheap to power offshore where charging them provides an option to reduce energy wastage in the sector,” the firm adds, emphasizing yet again the optimization value of offshore charging infrastructure.

Boatwise, the technology pieces are in place for batteries, electric propulsion, and related systems. As Bibby advises, the offshore charging element remains a challenge. “To deliver the infrastructure for offshore charging, clear licensing and permitting support for its roll out is needed,” the company explains.

“Developers investing in offshore charging infrastructure for their wind turbines will be seeking assurances that they will see a return on their investment through lower operating expenses and savings on emissions taxes. Regulators need to ensure that the economics will stack up for them today,” Bibby adds again for good measure.

Bibby also takes note of the regulatory environment in the European Union, where offshore wind activity has been flying thick and fast alongside the UK industry, too. Under the new FuelEU Maritime framework, CSOVs will be called to account for their carbon emissions. “Driving this vessel class to electrification will be an important step towards lowering costs and supporting offshore wind’s decarbonisation mission,” the firm explains.

Bibby is not waiting around for others to do the heavy lifting. Last year the company began building its new eCSOV while working with the firm Stilstrom and other partners to accelerate progress on offshore charging. “The teams are addressing complex integration challenges, from dynamic positioning interactions and charging regimes under varying weather conditions, to crew training and operational maintenance, ” Bibby explains.

More Electric Boats For Offshore Wind Farms

If all goes according to plan, the new vessel will be in operation by mid-year 2027. By then, perhaps the dust will have settled over Trump’s war in Iran. Or maybe not, as the case may be. After all, Iran has two areas of attack close at hand that impact energy markets. Iran can bomb oil and gas infrastructure in neighboring Middle East states, and it can send maritime traffic scurrying away from the Strait of Hormuz, a key global shipping lane. It has done both, of course.

Somewhat presciently, in a press statement just a few days before Trump began dropping his bombs on Iran, Bibby Marine CEO Nigel Quinn reminded everyone that “eCSOVs will empower operators to break free from the volatility of fossil fuel markets, with electricity costs aligned to a farm’s own clean energy production, securing long-term OPEX planning.”

“This is the blueprint for a resilient, zero-carbon future,” Quinn emphasized.

Meanwhile, here in the US…oh, never mind. Stupid is as stupid votes. Trump didn’t get to the White House in 2025 by voting for himself 77 million times on Election Day 2024, and the stupid just keeps coming.

For the record, Trump tried to stop the offshore wind, and he failed. Along with the five offshore farms already under construction along the Atlantic Coast, last December a federal judge ruled that Trump’s executive order of January 20, 2025 was arbitrary and illegal, opening a window for other projects in the pipeline to move forward. In addition, Massachusetts has embarked on an agreement with Nova Scotia aimed at bringing offshore wind down from Canada to New England.

Over on the Pacific Coast, keep an eye on California, where plans for offshore wind continue to move forward. Oregon is also prepping for a new wave of offshore activity. After all, US presidents come and go, and this one will go as scheduled on January 20, 2029 — peacefully this time, one hopes.
