Reliable power, a top priority at sea
“An important part of our service to
the shipping industry, is the highly
technical installation and repair
work undertaken out at sea by factory trained
Vert engineers,” says Grant Robertson,
managing director, Vert Energy. “A reliable
power supply is a top priority in shipping.
For this reason, Vert Energy has tailored its
capability to assist vessel owners – not only
with routine maintenance programmes, but
also in emergency breakdown situations –
without interfering with the daily activities
on the vessel.
“Vert Energy’s field services encompass
re-assembly, installation and commission‑
ing, inspections and diagnostics, as well
as on site maintenance and repair. Recent
projects include the rewinding of a 750 kVA
exciter stator – in situ and below deck – on
board a vessel out at sea near Mozambique.
There were no interruptions to the normal
operation of the ship. Vert technicians have
also installed and commissioned the retrofit‑
ment of new generators on board a vessel
in Namibia. These units were tested under
various loads and operating conditions out
at sea,” recounts Robertson.
Vert Energy has been appointed exclusive
distributor in sub-Saharan Africa for the sales
and support of DEIF generator controls. DEIF
power management systems encompass
diesel, gas and hydro control technologies for
offshore vessels and on/offshore platforms,
as well commercial, military and leisure
vessels. Special vessel applications include
dredgers, fishing vessels, heavy lift ships and
pipe laying vessels.
DEIF’s safe and reliable systems ensure
optimum performance, high accuracy,
minimal maintenance requirements and
reduced downtime. The company’s ‘green
technology’ focuses on energy efficiency, fuel
optimisation and reduced emissions.
DEIF products for marine and offshore ap‑
plications include analogue instrumentation,
single and multi-function controller platforms
and engineered solutions for the offshore oil
and gas industry’s ships and rigs.
These user-friendly controllers, which
eliminate the need for external controllers,
encompass advanced load dependent stop/
start controls, integrated remote control from
alarm and monitoring systems, long-time
parallel operation diesel/shaft generators and
combined emergency/harbour generators.
Vert Energy is also the exclusive distribu‑
tor in sub-Saharan Africa for Leroy Somer
alternators and Covrad heat exchangers. q
DIN 4754 guidelines according to the
German Institute for Standardisation for
preliminary flow monitoring, minimum oil
level monitoring in the expansion contain‑
er, temperature supervision of preliminary
heat and flue gas, as well as preliminary
temperature regulation. All boilers have a
CE construction design licence complying
with Module B of the EC Pressure Device
Directive 97/23/EG,” notes Botha.
With the backing of a global entity like
HTT, Energas Technologies has expert
product support from a single source,
which it carries through to its customers.
Says Botha: “The support ranges from
consultation and planning of novel prod‑
ucts and extends to customer-specific
engineering and project finance. Whether
it’s a completely new system, an expan‑
sion or modernisation or a refurbishment
of used systems, Energas Technologies is
well-positioned to develop customised
solutions for its clients.”
Concluding, she says: “With prod‑
uct maintenance, after-sales service, a
24-hour service helpline, spare parts
supply and training for our customers’
employees, we ensure the sustainable
and smooth operation of our clients’
systems and equipment.” q
