It is proposed to construct a 10.5m high structure with a 3 mile nautical light positioned a minimum of 6m above mean high water springs to replace the existing Portain Buoy. The structure will be coloured predominantly green to act as a day mark and a ladder is to be provided from mean low water level to the working platform to allow for safe access during future maintenance visits and inspections.

A 4m high cylindrical gravity concrete base foundation will be formed directly onto the bedrock using 3.0m precast concrete manhole rings as permanent formwork which will be filled with marine grade underwater concrete and stainless steel reinforcement during the works.

Once the concrete has cured and reached sufficient strength, the pre-fabricated stainless steel structure will be connected to the foundation using 8 no. M30 stainless steel threaded holding down bolts which will cast in during the concrete pour. A ladder leading to the working platform shall be attached to the main support colum which will allow safe access to the LED lantern and topmark located at the top of it.
