More than 7500 oil and gas platforms and wind turbines will become obsolete in the next few decades. Full removal may not be the best plan after all, according to new survey of international experts.
Current policy is that “leaving the seabed as you found it” is the best way to minimize environmental impacts. This is may not be the case.
Over their 20-30 -year lifetime, offshore platforms and wind turbines often develop into artificial reefs. These can have high biodiversity and form part of the ecosystem around them on which a wide range of species may depend.
NINA contributed to the survey with 38 international experts from research, government and industry. Almost 95% answered that a more flexible and case-to-case approach to the decommissioning of offshore equipment would be better for the environment.
