New Slipway Cradle Design for Portavogie Harbour
Model of the new slipway cradle
Qualter Hall & Co Ltd has appointed KGAL to design a new slipway cradle arrangement for Portavogie
Harbour in County Down, Northern Ireland on behalf of the ultimate Client, Northern Ireland Fishery
Harbour Authority.
Portavogie is a busy fishing port that has become an important
maritime centre because of its location and rich supply of seafood
in local waters. The harbour has been the economic and social hub
for the village since its construction in the 1800s.
Our scope is to design the moving cradle arrangement, complete
with hydraulic operated boat clamping carriages and operator
tower, with Qualter Hall designing the main winch equipment and
hydraulic system. Construction and installation is to be performed
by Qualter Hall.
The purpose of the cradle is to haul fishing vessels out of the
harbour and, when berthed, perform refurbishment duties as well as
the demolition of defunct vessels. The system is designed to accept
an array of vessel sizes, from 3.5m to 9m beam, up to 30m long, and
to accommodate a maximum vessel weight of 570 tonnes.
