Humber Oil Terminals, leasehold owner and operator of Immingham Oil Terminal in north-east England, UK, has proposed a harbour revision order to take its facilities out of Associated British Ports (ABP) control.
The proposals by Humber Oil Terminals Trustees (HOOT) are outlined in a letter and will go under review.
Meanwhile a master plan for the development of Immingham Port over the next 20 years has been unveiled.
Proposals include the creation of hundreds of jobs and making the port a centre for green energy. Owner Associated British Ports says the port must continue to play a vital role in the region's economy.
Immingham Port currently employs 4,700 people and supports over 15,000 of the South Humber workforce. The plan has been put out for public consultation.
It is understood that ABP has not renewed HOTTs exclusive lease on the terminal. A port masterplan outlines proposals for ABP to take over and make wider use of the facility, which currently serves ConocoPhillips Humber Oil Refinery and Totals Lindsey Oil Refinery joint partners in Humber Oil Terminals Trustees.
