ROUND UP
Liquid–tight technology for subsea vehicles
Elquip Solutions has introduced a high-end, com-
prehensive range of flexible conduit systems and
components from UK manufacturer Flexicon to
the local market.
These conduit systems provide superior cabling
protection, particularly in high-demand, hazard-
ous environments such as in the rail or mining
industries. Further demonstrating its versatility,
Flexicon’s liquid-tight conduit system has been
used to protect the power supply to subsea
remotely-operated vehicles (ROVs) in the oil and
gas industry in Brazil, China and Australia.
The 63 mm LTP conduit and
special engineered fittings are
used to protect the slipring con-
nections inside the winch. This
provides 3,3 kV feeds to the
power transmission system,
which connects the subsea ROV
to the surface, according to Mike
Cronin, managing director of
Elquip Solutions.
“In addition to the power ca-
bles, fibre optic elements are
included in the single cable con-
nection system called an ‘umbili-
cal’.The tail from the slip ring is a
loose bundle of copper and fibre
optic cables, which terminates in a junction box
on the winch. This bundle needs protecting from
sea spray and harsh offshore environments to
maximise its service life and provide trouble-free
operation,” says Cronin.
In the subsea environment it is essential that
power is maintained for data to the ROV, because
when the ROV is not working, it means the entire
rig is down and not drilling. Providing ongoing
protection for the slip ring from the environment
is therefore vital.

Specially plated – more stability
The increasing modularisation of industrial pro-
duction facilities and the rise in mobile equipment
employed is resulting in growing demand for
connectors capable of High Mating Cycles (HMC).
The launch of the new Han-Modular Hinged frame
HMC now enables the integration of Han-Modular
components into HMC connectors.
The Han-Modular system can now handle HMC
as well – the key component being the new Han-
Modular Hinged frame HMC which is designed to
handle more than 10 000 mating cycles.The new
Han-Modular Hinged frame HMC sets itself apart
from conventional hinged frames in particular in
terms of the PE contact. The contact is specially
plated and boasts increased
fixation stability in the frame
of the Hinged frame HMC.
Since the Han HMC hous-
ing is executed with IP65
protection, the new HMC
hinged frame also opens
up new application fields for
Han-Modular. Not only can
Han-Modular connectors
be plugged and unplugged
many thousand times, the
modules in HMC housings
are also especially well pro-
tected against mechanical
loads, contact and dust
accumulation as well as
against water spray.
