Mariner field is Equinor’s first operated development in the UK North Sea.
Wood Europe and Africa operations services business president Craig Shanaghey said: “We are delighted to extend our strong partnership with Equinor to include support for their operations at the pioneering Mariner field.
“Wood has a long-standing track record of partnering with our clients to deliver safe, reliable, and optimised operations in the UKCS, and we look forward to extending that to include Mariner by leveraging our deep operational knowledge, experience, and digital capability.
“Mariner is still in its early years of production and, with Wood’s ambition to realise a digitally enabled future, we see excellent potential to explore new opportunities that will promote a lifetime of sustainable and responsible operations at the field.”
In February, Wood Group secured a contract from Chevron to deliver engineering design project for Anchor deepwater development in the US Gulf of Mexico.
