In a statement Subsea 7 said that concerning the renewables business, “last year’s project delays and cancellations put many countries’ clean energy ambitions under pressure and prompted a swift response in countries such as the UK and US, with positive indications for our tender pipeline in 2024.”
It added: “While the growth trajectory for the offshore wind market may not be smooth it is certainly clear that long-term demand is set to significantly exceed the current fleet capacity of the industry.
“With a strong focus on achieving an equitable risk-return balance, we believe our offshore wind business will deliver sustainable value creation for shareholders.”
