51 ̊   56.96 N       0001 ̊ 12.00 E         to           51 ̊   56.93 N       0001 12.93 E

Please note that the distance between the above latitude and longitude positions extends approximately one nautical mile.

The following vessels will be involved in the mooring installation; Ashraf, Tasks 2, Megan M and Schwartenbek. Please note that two floating pontoons (16.2 m LOA and 10.26m Beam) will also be used.

All vessels passing these works should do so with care and caution and with minimum wash at all times, especially when men are working on the waterline.

Mooring work deployment should be completed by the 11th of April 2018. It is anticipated that the temporary moorings will be removed by the 30th of June 2018.

Mooring buoys will be lit with an all-round white light. No vessel shall moor to the buoys without the expressed permission of the Harbour Master.

Once the trot moorings are in place four pipelines will be towed into the haven and positioned on the moorings. This work is part of the East Anglia Offshore windfarm operations compromising of 102 turbines. Due to the length of the pipeline navigational restrictions and risk mitigation measures will be implement during towage operations. An additional Notice to Mariners will be promulgated clarifying these arrangements.
