Modular Over-The-Side Deployment Pole
Description
A modular, transportable, over the
side deployment pole for Sonardyne
USBL systems, designed for vessels
where through-hull deployment
options is not available or practical.
Designed from years of experience
on many vessels and careful
modelling, the high performance
pole enables survey grade
positioning from any vessel of
opportunity so reducing operating
costs and extending capability.
The high integrity design and deck
level actuation reduces potential HSE
concerns seen on some installations.
Manufactured from high grade steel,
the highly rigid pole includes vortex
shedding strakes to reduce drag and
vibration which can reduce
performance.
Once deployed the pole is locked
into place via a heavy duty
hydraulically operated mechanism
welded to the ships hull. When the
lock is engaged it increases the
stiffness of the pole and ensures a
high degree of repeatability when
raised and lowered.
Installation is made easy with deck
or hull mounting options. The poles
length can be adjusted by adding or
removing sections. Lower sections
are simple to change and cost
effective to replace. Each section is
fitted with lifting lugs positioned at its
centre of mass.
Longevity and robustness are
enhanced by fabrication from hot
dipped galvanised steel which is
then over coated with a two part
marine epoxy.
The pole’s design makes assembly
easy by incorporating internal
protected ducts for the hydraulic hose
(for the locking mechanism) and two
cables to the pole end.
The design allows the fabrication of
a range of adapters offering a high
degree of flexibility in the type of
equipment that can be attached and
deployed from the pole.
