Local junction box assembly
dramatically improves the availability
of customised products
Issue 21, November 2012
JT Day’s new junction box
assembly facility, believed by
Hawke International to be one of
the best equipped workshops within
the Hawke International group of Ex
junction box modifiers is now up and
running.
Our first focus will be assembly of the
ever-popular PL range from Hawke.
The facility has been established to
offer greatly improved turnaround
of customised junction boxes to the
marketplace.
DESPERATE CALL
A terrific example of its purposes was
demonstrated during late October, when the
doors to the workshop had been open for
literally only a few hours.
Our sales team received a desperate call
from a long-standing client who required 150
custom boxes for a rectification program for
one of their offshore assets.
The boxes were completed on time and
delivered for immediate installation.
National Sales Manager, Shawn Taylor said
“It’s this type of service level we want to
maintain as we build on and expand our
service offer to the market. It’s all about
being able to deliver a flexible solution in the
quickest timeframe.”
The assembly facility, established by Hawke
International personnel who were brought
from the U.K. to our Perth facility, covered
across areas such as sales, QA, safety and
assembly.
PRECISION WORK
The workshop provides precision drilling and
tapping of cable gland and breather entries,
punching of continuity plates and terminal
assembly utilising the ever popular terminal
products and accessories from Weidmuller.
The assembly service is provided under
close scrutiny of our Lloyds Register ISO
9001:2008 quality program and under
the tight control of IEC EX certification
for hazardous areas so that our
clients can be assured it will be to full
specification and standards.
WELL PROVEN
The PL box from Hawke is well-proven
and very popular within the oil & gas
market both onshore and offshore as
they demand product that is robust and
will withstand the harsh and hazardous
environments.
The PL range is the ultimate in robust
GRP construction and the PL6 series
is designed to withstand impact resistance
up to 20Nm. The one piece durable captive
moulded silicone gasket provides ingress
protection to IP 66 & 67 and in addition meets
the stringent Shell DTS01 deluge test.

Two ships fitted and one
to go with the unique
Hawke Transit System
Delivery of supplies of Hawke Transit
Systems from JT Day for the three
new Hobart Class Air Warfare
Destroyers has been proceeding steadily.
Supplies have been delivered for two
ships with another due for supplies when
construction work is ready to receive them.
The three destroyers are being built for the
Australian Government by Adelaide-based
shipbuilder, ASC.
ASC chose the Hawke Transit System to
maintain integrity of bulkheads and the
deck areas through which electrical cables
and piping pass as the transit system is a
particularly good product for pressure sealing
against fire, water and gas.
One of the unique aspects of the Hawke
Transit System is colour coded blocks that
Hawke’s unique colour code system
ensure the top and bottom halves of each
block are correctly matched for size so that
the chances of errors can be minimised.
These blocks in seven sizes ranging from
3mm to 100mm in diameter have been
designed with a degree of flexibility to
accommodate variances in cable diameters.
As a consequence they offer a simpler,
speedier process of installation than that
offered by other systems.
These size-tolerant blocks are made of zero
halogen, intumescent elastomeric polymer
with five sealing faces that are displaced by
the sealing process to give a tolerance of up
to 4mm for cable diameters.
Meanwhile the Federal Government has
announced that the $36billion Future
Submarines project will be going ahead, also
based in South Australia.
The project will be the largest and most
complex Defence project ever undertaken by
Australia, involving hundreds of companies
and thousands of workers.
LED lighting

THERE’S NO DOUBT LEDS ARE NOT A PASSING FAD
Traditional products like fluorescents,
floodlights, bulkheads, and wellglasses
using traditional lamp
sources, such as fluorescent or HID,
will not disappear overnight but with
the continuing improvements in LED
technology, this new light source is
proving to be ideally suited to oil and gas
installations because of safety factors and
reduced energy usage.
Ian MacLeod, a spokesman for Chalmit
Lighting, our principal supplier of lighting for
the oil and gas industry, makes the point that
whether using older or newer technology
there are pros and cons to the best use
of products, dependant on many factors,
ambient temperature, installation cost and
maintenance costs, to name just a few.
Chalmit has been manufacturing Ex LED
products since 2004. Their Nexled bulkhead
light was the first hazardous area product
utilising LEDs as the main light source. Over
10,000 have been installed worldwide.
The first ventures into LEDs concentrated
on smaller products using low to medium
power LEDs, but as the technology has
improved their designs have been scaled up
to give products delivering output to match
fluorescent and HID lamps.
Ian MacLeod said that in designing with LEDs
it is important to ensure they do actually
perform as expected – putting the required
amount of light (lux) on the working plane.
In order to ensure designers and users can
be assured of the right product for the job,
Chalmit releases photometric details that
provide an indication of the levels of light
output.
Another important
factor with LED
products is the life,
not only of the LED
but of the complete
luminaire. Chalmit has a long history of
designing and manufacturing products that
are robust and suitable for the challenges
thrown up by oil & gas installations and have
used the knowledge to ensure that the key
parts of any LED luminaire – the LEDs and
the driver – can cope.
Another benefit of LED technology is that the
components are similar worldwide. No longer
are there situations where European lamps
and control gear differ from US lamps and
control gear – they’re all using similar solid
state technology.
In the very near future Chalmit will have a full
range of Ex products utilising LEDs. When
these are added to the already extensive
range of Ex products using existing lamp
sources, the range of choices will be huge.

Why earthing is important
By Paul Hollingsworth, CEO Lightning Protection International
The installation and maintenance of
an effective low resistance earthing
system is essential for any modern
facility for three key reasons:
▪▪
▪▪
▪▪
Protection of personnel
Protection of equipment
Ensuring electrical noise reduction to
minimise voltage potentials between
interconnected equipment
The requirement for effective earthing is
critical when considering the following
applications:
▪▪
▪▪
▪▪
▪▪
Lightning protection
Power generation, distribution and
transmission
Telecommunications
Reduction of static electricity
The key parameters of an efficient
earthing system
In order to achieve a low resistance and
impedance, earth connections should be
short and direct as possible.
Maximising the surface contact between
the soil and all electrodes and conductors is
essential for efficient performance.
The system needs:
▪▪
▪▪
▪▪
▪▪
▪▪
Excellent electrical conductivity
Low earth resistance and impedance
Conductors capable of withstanding high
fault currents
Robust mechanical connections to
facilitate a long working life
High corrosion resistance
Materials chosen for earthing systems should
offer an acceptable compromise between
cost and longevity. Compatible metals must
be used to minimise corrosion.
▪▪
Equipotential Bonding
The elimination of dangerous step and touch
potentials is achieved through equipotential
bonding of all earths.
The importance of low soil
resistivity
The resistance of the earth itself (earth /
soil resistance) is the greatest influence
on overall impedance of an earthing
system.
Factors such as soil composition, moisture
content, seasonal weather, mineral content
and possible contaminants determine
resistivity.
Moisture content is the single largest
influence and in most cases, the higher the
moisture level the lower the soil resistivity.
The installation of a deep driven earthing
electrode that reaches the water table
beneath the surface represents an ideal
earthing system.
▪▪
▪▪
▪▪
Rich dark soils high in organic content
are typically good conductors due to
moisture retention which aids in the
dissipation of electrical currents.
Sandy soils are ineffective in retaining
moisture and typically have higher
impedance.
Rocky ground retains virtually no
moisture and is very high in resistance.
Designing an earthing system
There are several factors to consider
when planning the design of an earthing
system.
▪▪
Applicable standards and codes to be
followed:
For power system earthing IEEE 80 or other
international derivations are widely used.
These standards are usually mandatory
and some level of expertise is needed to
undertake designs to these standards.
For lightning protection / static earths
commonly used standards are IEC62305,
AS1768, NFPA 780. These are often not
mandatory but provide recommendations.
▪▪
▪▪
▪▪
▪▪
▪▪
▪▪
▪▪
▪▪
▪▪
▪▪
Type of facility and the site layout in
regards to available space
Level of soil resistivity at site
Influence of seasonal weather conditions
on soil resistivity
Corrosive nature of soil and
consequently materials chosen for use
Expected life of the facility will affect
material choices
Future extensions
If applicable the status of any existing
earthing system
Step and touch potentials
Volume of pedestrian traffic
Finally, but most importantly, the quality
and compliance of hardware used in
the earthing system installation is a
major determinant of the reliability of the
earthing system.
This is why some standards for design also
have requirements associated with testing
and certification of components. Some
applicable testing standards include IEEE
837, and EN 50164.
