The reports are yet to be received, the company noted.Although there are no additional persons with symptoms at the field, medical staff are following up the 776 persons working on the project and spread across three offshore installations.Equinor plans to reduce the activity on Martin Linge fieldEquinor said it plans to reduce the activity on the field and is assessing further measures to prevent the contamination.The field is scheduled to commence production by the end of 2020. The development plan comprises a jacket-based integrated wellhead, production and accommodation platform and a permanently anchored oil storage vessel.The field, which is located 42km west of the Oseberg field in the Norwegian North Sea, is operated by Equinor with 70% stake. The remaining 30% stake is held by Norway’s state-owned Petoro (30%).Recently, Equinor has pledged to at least halve its carbon intensity by 2050, a goal that includes emissions generated by the consumption of its oil and gas products by end-users.
