The new tower at Rossall Point, which will reach 14 metres (46ft) upon completion, will act as a base for the UK's National Coastwatch Institution.
A platform at the top will be open to the public providing ample vistas of the Irish Sea's marine wildlife for birdwatchers and more, while the view from the top will also be projected on a screen in the education centre to be located in the tower's ground floor.
The works involve the installation of four steel piles - two in the navigation channel to the inner harbour and two to the west of Dinish Pier.
The works are being advanced by civil engineering crews working from a jack-up barge, which will display the relevant day signals and navigation lights in accordance with collision regulations.
For safety reasons, mariners are requested to proceed slowly and with caution in the approach channel to the Fishery Harbour Centre and to give the works a wide berth. Wave-wash from vessels should also be avoided.
These works are expected to be on-going until mid-December, weather permitting.
Complete details for shipowners, ship operations, shipmasters and seafarers are included in Marine Notice No 57 of 2011, a PDF of which is available to read and download HERE.
