UK ferry operator undergoing a marine gas oil conversion contacted us with a requirement for a marine gas oil pump with Lloyds approval. Their previous marine fuel pump was no longer compatible due to the lower viscosity of MGO compared to heavy fuel oil (HFO). They needed this pump delivered within 3-4 weeks to meet the vessel's dry docking programme. This was a very tight deadline as normally pumps like this are supplied on a 4-6 week lead time.
Vessels are increasingly undergoing conversions from HFO to fluids such as MGO due to the legal requirement to comply with emission targets set in the Sulphur Emission Control Area (SECA). The Low Sulphur Directive now requires ships to use fuel with a maximum of 0.1% sulphur content in Emission Control Areas. New marine fuel pumps are usually required for compatilbilty with the change in fuel now used on board.
- Ability to handle the lower viscosity of marine gas oil
- Tight customer deadline to meet docking programme
We specified a cast iron, vertical inline screw pump; a pump design ideal for handling the lower viscosity and lubricating properties of marine gas oil. We choose to supply screw pumps over gear pumps, which as also popular for the transfer of fuels, due to their better mechanical efficiency, smaller footprint and smoother, quierer pumping.
The pump also came complete with suction and discharge manometers to satisfy class requirements. The pump was delivered complete with a pressure relief valve, set as per the customer’s request, enabling the pump to avoid damage should it experience higher than expected pressures.
Thanks to the fast track production programme that we offer as the agent for Azcue pumps, we were able to supply the screw pump, complete with the Lloyds marine certification in 3.5 weeks, enabling the customer to meet the vessel's dry docking programme and avoid any demurrage. Due to our quick response in supplying the marine gas oil pump, the customer also requested us to supply an accompanying flow meter and DN80 strainer for their new onboard fuel system
