Maersk Fluid Technology exhibits at the Danish Maritime Fair 2016

Maersk Fluid Technology (MFT) will be present at the Danish Maritime Fair 25th – 27th October 2016, on stand number 0520, with actual examples of the company’s Blending-on-Board (BOB) system and the associated XRF scrapedown oil analyser.

BOB was developed in 2008 by Maersk initially for the A.P Moeller group’s own ships, and over 200 installations in Maersk and other fleets have now logged millions of cylinder operation hours. The technology has proved reliable, and is now in its third generation, which is being made available commercially and is being shown at Danish Maritime Fair for the first time under the ‘SEA-Mate’ brand name.

MFT will be presenting a new blender, the SEA-Mate B500, which is specifically designed for engines with a bore size 26 - 48. With the new unit, along with its larger alternatives, the SEA-Mate B1000, bore size 50 – 72 & B3000, bore size >72, there is now a suitable SEA-Mate blender for all 2-stroke engines.

BOB has been used with both Wärtsilä/WinGD and MAN B&W engines, and both companies have issued letters of no objection to the use of BOB technology.

Maersk Fluid Technology (MFT) will be present at the Danish Maritime Fair 25th – 27th October 2016, on stand number 0520, with actual examples of the company’s Blending-on-Board (BOB) system and the associated XRF scrapedown oil analyser.The system utilises the in-use system lubricant as base stock, and blends it with a high-alkalinity (which may be as high as 300BN) cylinder oil concentrate to produce a cylinder lubricant with the optimum base number (BN), anything from 40BN up to well above 100BN.

With current industry concerns about cold corrosion, and the need to adjust fuel sulphur levels to meet emissions limits, the importance of using cylinder oil of the correct alkalinity level has never been greater. Experience in some of the world’s largest fleets has proved that BOB is a simple, low-cost, flexible, reliable and environmentally-friendly method of achieving this.

Run at minimum recommended cylinder lubrication regardless of fuel sulphur content.

Sune Lilbaek, Head of Sales at Maersk Fluid Technology, explains: “The BOB system added to the existing lubrication system and after installation it will no longer be necessary to adjust cylinder oil feed rates is needed regardless of the sulphur content in the fuel oil. When switching from traditional lubrication oil to our future-proof blending system, experience with the current 200 installations has proved that it will be possible to achieve lubrication at or close to the lowest allowed consumption of lubricant as specified by the engine manufacturer. This results in the cylinder lubricant from the BOB system always matching the sulphur content in the fuel. It is no longer necessary to increase lubricant supply to counter corrosive wear or fouling - instead the concentration of BN and other additives are adjusted on-the-fly, creating a fit-for-purpose cylinder oil at same or better quality than a standard fixed-BN cylinder oil. Being able to match lubricant with the fuel in use translates to proven reductions of up to 40% in cylinder oil consumption. Once the system has been set up, on-board engineers will merely need to enter the sulphur content of the fuel in use and the system will automatically blend a cylinder oil matching the fuel sulphur – the process can be fully automated and does not require interaction from the operator. “

Best of all - BOB is easily retrofitted to existing vessels.

Utilising the in-use system oil for blending is a clear-cut win for the engine

As the oil used for blending down the concentrate is taken from the in-use system oil, system oil is frequently replenished with new stock. This prevents the oil quality deterioration that otherwise takes place for any system oil. As a result, anti-wear and detergency properties are as for a new oil and on top of this, the system oil viscosity is maintained and waste system oil disposal and oil cleaning energy consumption is reduced by up to 80%.

Experience has shown that by maintaining the original viscosity of the system oil, friction losses are reduced and fuel consumption has proven to be cut by up to 1.5%. Cleaner system oil has, in addition, a positive impact on wear of components and maintenance of separators and filters. Taking into account the reduced fuel and lubricating oil consumption and lower waste oil disposal costs, payback times of less than two years can be expected.

Try the SEA-Mate on-board oil analyser at Danish Maritime Fair – bring your own sample

The SEA-Mate M4000 XRF analyser, which will also be on display at the Danish Maritime Fair, is an accurate lubricant analysis tool that can provide accurate and reproducible results within 7 minutes, rather than the average two-week delay in obtaining laboratory results. Although it is perfectly possible to utilise BOB without the analyser, including the M4000 as part of the system facilitates fast and precise evaluation of every lubrication adjustment made. The M4000 is the only system intended for onboard use, which gives a precise on-board measurement of both corrosive and abrasive iron in scrapedown oil, making it possible to identify if corrosive wear is taking place and take appropriate action without delay.

At the Danish Maritime Fair, visitors will have the opportunity to try out the M4000 Analyzer using example as well as own scrapedown oil samples, as well as to calculate savings that can be expected through using BOB.
