Eco Lube H46 at Bakker Sliedrecht

Environmental risks are curbed by the use of sustainable lubricants. Machinery can perform best with minimum quantities of lubricant. Bakker Sliedrecht, partner for total solutions in the fields of maritime and industrial electrotechnics, put this into practice. Arie Boer, Business Development Manager and Bram Redelijkheid, in charge of the machine department, explain how they are preparing for the future and are taking their starting point from maximum security for their customers.

“We often found ourselves discussing environmentally friendly lubricants,” says Bram Redelijkheid (Bakker Sliedrecht machine department). “Although they don’t seem to have top priority in the Netherlands just yet, the day will dawn of ever-increasing market demand. Due to developments around the world, we can no longer deny that things are stirring in this respect. In countries like Australia, Alaska and the Scandinavian countries, sustainability is already growing in importance.


Knowledge with respect to biolubricants has improved appreciably over the past few years. Partly thanks to Reach / GHS, more as well as more extensive information on raw materials has become available, making it increasingly easier for producers to select performance requirements and technical specifications for machinery based on more environmentally friendly components, such as base oils, thickeners and / or other additives. A range of high-performance lubricants has thus been created using mainly renewable raw materials.

The environment

Redelijkheid: ‘We got to talking with Interflon, which suggested an environmentally friendly Interflon Eco Lube H46 as a solution for us. Jan de Nul was prepared to test the product and, together with INDAR, the supplier of the underwater motors, we set to work. We had three identical underwater motors, so we could easily compare them to see whether there were any differences between

conventional oil and Interflon’s eco-friendly oil. As a system integrator, we vouch for the complete systems, so it is important that we carry out a reliable study before pronouncing ourselves in favour of any product changes. Our many years of experience have made us more aware than anyone of how important operational safety is to dredging companies. It is essential that their production carries on. Stoppages have huge consequences and all risks have to be ruled out. Extensive risk analyses are therefore a standard part of our procedures. Not only the environment, but also safety and economic interests weigh heavily in the decision-making process. It is a fact that the environment will be a consideration to be reckoned with.'


Based on his years of experience, Arie Boer, Business Development Manager at Bakker Sliedrecht, explains the importance of the requirements that must be met: ‘Dredging is a specific market that stays on top of developments despite its somewhat reserved character. We are keenly aware of the importance of dredging activities and the high costs that a machine stoppage can incur. After all, you can only take responsibility for the systems if you are certain of their high performance. We would therefore always notify our clients of any changes, such as the use of a new lubricant, and discuss those changes with them.

It is always a range of factors that feature in these decision-making processes. With respect to hydraulic oil, electrical properties, insulation, performance, price, the environment, life span, etc., figure along with the good lubricating qualities. The issue is the expense of these operations. Imagine that a motor has to be removed. This involves huge costs. In this type of business, continuity is most definitely the magic word. That is why several ships are even equipped with satellite connections, enabling us to monitor the systems and, if necessary, help the vessels on site, no matter where they are in the world.’

Eco-friendly oil in actual practice

Boer: ‘In my experience, new developments are always implemented one step at a time. So, too, this new step with environmentally friendly lubricants, such as eco-friendly bearing lubricants and lubricants for hydraulic systems. Interflon Eco Lube H46 – made of plant-based oil – is safer to work with. It contains no hazardous substances and is therefore less damaging to the environment. Hydraulic systems can easily contain 3000-5000 litres of oil. Imagine the tremendous impact on the environment should a problem occur with conventional oil. Interflon guarantees the high-performance lubricating qualities of its product.’


We therefore asked Interflon to compare the Interflon Eco Lube H46 measurements with the conventional oil our company uses today. Dielectric Strength, Conductivity – or conductivity of an electrical component for conducting electrical power – the PourPoint and the Demulsibility – the ability to break down oil mixed with an amount of water into its separate parts – came through extremely well. The comparison clearly shows that performances were at least equal to or even better than the oil we have advised to date. We can now offer our customers in the dredging industry eco-friendly oil without any qualms, as we have been unable to detect any risk on any count in the test. According to the supplier, this oil’s life is five times longer than conventional oils and it reduces energy consumption and oil temperature. Furthermore, it is compatible with virtually all types of hoses. We see no reason not to change over. We would like to make the switch together. Our confidence in the product has been substantiated. Actual practice will prove that efficiency and respect for the environment can go perfectly well together.’
