Europe Gasoline/Naphtha-Gasoline margins fall on slow buying

LONDON, March 11 (Reuters) - Northwest European gasoline refining profit margins fell by 67 cents on Tuesday to $4.03 a barrel on weaker buying activity.

• A total of 4,000 metric tons of E5 gasoline barges traded, as Litasco sold to Glencore.

• A further 4,000 tons of Eurobob E10 traded, as TotalEnergies sold to Shell.

• Shipping operations resumed at commercial ports in Britain's Humber estuary on Tuesday with no special measures in place following a collision in the North Sea, but movements in and out of ports were still affected by the incident.

• The four ports under the authority of Associated British Ports - Hull, Immingham, Goole, and Grimsby - had been allowing vessels in and out since Monday night, following the collision at sea of a container ship with a tanker, an ABP spokesperson said.

• Nigeria's state oil company NNPC Ltd has begun discussions with the Dangote Oil Refinery to extend its contract for supplying crude oil in the naira currency, the company said.

• The original six-month agreement, which ends later this month, was implemented in October after local refineries, including the Dangote facility, reported difficulties securing crude supplies.

• EU and UK gasoline exports are on track to reach 435,000 barrels per day in March, according to Kpler data, compared with 879,000 bpd in February.
