Active notices:
6 July 2026: Maldon Harbour Dredging Work
Mariners are advised that dredgers will be operating in Maldon Harbour during high tides on multiple dates and at various locations from 1 July 2026 to 1 April 2027.
The dredging vessels will be constrained in their manoeuvrability and draught, and will frequently be stationary. They should be given a wide berth.
The dredgers will be contactable in emergencies on VHF Channel 16.
Notice issued for and on behalf of Maldon Harbour Improvement Commissioners.

17 February 2026: North Falls Offshore Wind Farm.
Overview:
Mariners are advised that North Falls Offshore Wind Farm (NFOWF) will undertake a metocean survey within the Wind Turbine Array Area, at the Primary and Secondary locations shown in Table 1 and Figure 2.
Survey Duration:
Mobilisation will commence on or after 18 February 2026, with the metocean survey lasting between 12 and 18 months. The planned survey end date will be no later than 16 August 2027.
Survey Tasks:
The metocean survey work is being undertaken by Partrac, who will use the vessel CT Vector to deploy the metocean equipment at the Primary and Secondary locations listed below. It is expected that the deployment operation will last for one day.
The metocean equipment will consist of one seabed frame deployed at each location (i.e., a total of two seabed frames). Each seabed frame will be equipped with an acoustic Doppler current profiler (ADCP) and additional sensors (temperature sensor, water-level sensor, and turbidity sensor). Each seabed frame will be connected to a clump weight, with approximately 100 m leaded polypropylene ground line between the seabed frame and clump weight.
As a consequence of equipment being deployed, all mariners are advised to keep a safe clearance distance of no less than 500 m from the deployment vessel and metocean equipment deployment locations. No towed survey equipment will be deployed from the vessel.
