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

Reliable power, a top priority at sea “ A n important part of our service to the shipping industry, is the highly technical installation and repair

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

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
