The blending of two or more fluids at a predetermined ratio to produce a finished product is a common operation in the Oil industry.
Blending the correct viscosity or density Fuel conforming to the exact specification of ISO8217 is important not only for the performance and maintenance of yours or your customers engines but also for the cost of the product.
In-line blending is a controlled, continuous process, mixing two components during the delivery process offering some major benefits, when the requirement is to produc high quality blended products.

  • Less storage space required (tank capacity)
  • No unnecessary surplus taking up space and capital
  • No product contamination/degradation from previous residual content
  • A wide range of products can be blended "in-line"
  • Just-in-time delivery
  • High flexibility
  • Less waste and loss
  • Accurate delivery of quantity and quality
  • The blend conforms to ISO8217:2010 and MARPOL 73/78, Annex VI, Regulation 14(1) and 18(1)

The metering system secures exact volumetric supply so a bunker barge can do more deliveries of multiple IFO qualities at precise volumetric quantity in less time than one or more traditional barges.


On a Bunker Barge the On-Board In-Line blending is a controlled, continuous mixing of two components in a device that secures the correct composition conforming to ISO8217 and in accordance with the predefined settings.
This procedure can now take place during the actual delivery to the customer vessel. 
In-line blending reduces the blending time and is a quick and easy process with no extra need for the costly on-board tank storage that is necessary when doing batch blending. Furthermore you avoid mixing the excess product volume that is often the result of batch blending operation.
With the improved flexibility of In-Line Blending you can supply a wide range of products to your customers independent of time and place.


We use Positive Displacement (PD) Flow Meters. These are the most accurate and reliable meters for measuring the volumes to be transferred from one storage to another.
The PD meter is the preferred choice of instrument by all parties to document Custody Transfer, Ship-to-Ship (STS) transfer and Physical bunkering to avoid getting involved in disputes and claims.
