![]() ![]() To perform due diligence and to prove best practice for the authorities, it is necessary to make a bunker plan. These are not huge conversions - in most cases it can be managed by pipework, valves and common sense. Re-designed fuel system for specific purposesįor vessels trading in routes where it will be necessary or profitable to change between cracked fuels and paraffinic fuels, we can re-design the fuel system for the specific purpose. To support you we have a small guideline which can be sent to you on request. A cleanliness/stability test is very simple and can be made locally without investment in expensive testing equipment. This way our recommendations can be close to bullet-proof.Ī cleanliness/stability test is a valuable tool for evaluating two products before blending and switch-over, especially until we get familiar with the new products. An even better option is for you to send us a physical sample which will enable us to make a compatibility test. ![]() Based on our evaluation we will give our best recommendations on stability and compatibility issues. Send us the ISO specification of the fuel onboard (as accurate as possible) and we will evaluate the parameters of the fuel you have ordered. Let us help you validate the fuelįrom our testing we have gained experience identifying the most problematic products and we offer a validation of the fuels prior to filling with our products. Inspection of bunker tanks should be part of the SMS and be performed as frequently as possible and no less than at every planned dry docking. ![]() We recommend inspecting as many tanks as possible prior to changing to 0.5% products and to dig out the piles, if any, with a shovel and buckets as necessary. ![]() This also happens occasionally today, but it is our advice that special attention should be given in places where the problem has never happened since the characteristics of the fuel will change. The biggest concern is if there are any piles of asphaltenes and cat fines in the tanks which might be dissolved by introducing more naphthenic and aromatic fuel into the tanks, jeopardizing the safety of the vessel with separator and filter problems. It is our conclusion that we will experience some compatibility problems, but not necessarily worse than we have experienced during the last many years. Also, we have now 5 years’ experience from changing between HS and LS for vessels trading ECAs. In close cooperation with one of the leading and most recognised fuel test providers we are testing all the new products we see in the market and can get hold on from various refineries and fuel blenders. ![]()
