A specialist in the provision of offshore DNV 2.7-1 containers, tanks, reefers, engineering workspace and accommodation modules, Ferguson Middle East, has recently introduced a new dual heating, ventilation and air conditioning (HVAC) system to its engineering workspace modules.
New air-conditioning unit for use in the Arabian Gulf
Temperatures reach approximately 40°C in the Arabian Gulf, and sometimes higher in the summer months, making uncomfortable work environments for offshore workers. Offshore crews need an air-conditioning system that offers a comfortable and cool workspace, thus protecting them from these conditions and this is exactly what the new Ferguson Middle East system has been designed to do.
Each HVAC unit is more powerful than standard units and is operational over a greater range of temperatures from -20°C to +50°C. Designed to improve temperature management, a two-speed fan has been introduced. As a result, working efficiency has been improved by 30% in normal operation and purge time has reduced by approximately 25% on wasted time when the module cannot be operational.
Addressing the challenge of working in such high temperatures
Dr. Julian Poyner, Engineering Director at Ferguson Group, said: “All offshore modules are pressurised and this means that they have cool air pumped through them at a constant rate whenever they are powered up. When you are dealing with a very warm ambient temperature the HVAC has to work a lot harder. Offshore, this can mean that the HVAC unit is under stress for days at a time, with the obvious risk to reliability.” Poyner continued: “We are delighted that we have been able to design a solution to meet the needs of our Gulf clients and can offer a solution that successfully addresses the challenge of working in modules in such high temperatures.”
