Helping To Cure Sulfur Emissions: Auramarine cooling system aids switch to low-sulfur marine gas oil
The new tightened sulfur emissions rules will become effective in the Baltic Sea, the North Sea, the English Channel and North America in 2015. The time for making the alterations required by the new regulations is running short.
One solution for meeting the reduced sulfur-emissions requirements is to switch from heavy fuel oil (HFO) to marine gas oil (MGO), which contains 0.1% sulfur.
Finnish company Auramarine said it offers a fast, reliable and affordable service for this switch. Auramarine’s equipment consists of three units: the fuel oil supply unit, the MGO cooling system and the Auramarine fuel selector. The fuel selector is an automatic system that controls the HFO to MGO changeover procedure.
“Our solution can easily be integrated with any heavy fuel oil feeding system, whether newbuild or retrofit,” said Isto Sakkara, director, Marketing & Sales, Auramarine Oy. “In the case of a newbuild, it is worthwhile to utilize Auramarine’s AMB FO (fuel oil) supply units, which have been designed to function seamlessly in an MGO solution.”
The Auramarine MGO cooling system chills marine gas oil even below 20°C so that the viscosity and lubricity meet the requirements of the engine manufacturers.
The ability of ship engines to utilize MGO varies considerably, and the company said its MGO cooling system enables practically all ships to switch to low-sulfur fuel. Auramarine’s fuel selector makes it possible to program the fuel changeover procedure to take place automatically, the company said. In addition to the automatic changeover process, the system can be controlled manually and ensures that the temperature change process is slow enough — the temperature of the fuel entering the engine must not change by more than about 2°C/min.
The fuel selector also provides for data reporting, saving the data on the PLC unit and converting it into a clear report for use by the shipping company and relevant authorities. The fuel selector allows the ship’s crew to monitor the process data in real time and the overall functionality of the system.
