|The works comprised of the design, delivery and installation of
34 No. precast concrete floating breakwater units (each 20m x
4m weighing approx. 60 tonnes), held in place by a flexible
mooring system on a helical mooring system designed &
developed by L&M Keating.
The site location on the Southwest Coast resulted in particularly
onerous environmental loading design criteria.
Environmental constraints placed a number of limiting conditions
on the footprint and materials for possible anchoring systems.
L&M Keating researched and sourced in New Zealand existing
helical anchor pile mooring systems used in sands & soft soils.
The design was developed through extensive site testing by L&M
Keating to adapt to coarser soil conditions. A new overwater
installation system was devised by L&M Keating which reduced
installation time significantly and almost eliminated dive work,
thereby reducing cost and health & safety risks. The mooring
and installation system further minimised disturbance of the sea
bed. In total 142 anchors piles were installed complete with
dyneema mooring lines.
A rock armoured fixed breakwater was also constructed
complete with rock armour protection and concrete access slab.
The existing northern quay was refurbished in the form of a
new concrete deck. Both were connected to the new floating
breakwaters via 2 No. access bridges.
The serviced concrete breakwater pontoons were designed using
proprietary mooring analysis and Ansys 3D modelling software.
The breakwaters include a highly aesthetic and hardwearing
structural wave wall of Ekki hardwood.
As part of this contract an RNLI berth is being provided for the
Severn Class RNLI lifeboat. The berth is to be fitted to the
highest standards including high level upstand fendering, lighting,
GRP decking and power.
