Bunker Samplers

Bunker Samplers for Fuel Delivery

IMO MARPOL 73/78 Annex VI compliant bunker samplers and bunker sampling accessories, available now for immediate delivery.

Fuel oil sampling is an essential element of any bunkering operation. Representative fuel oil samples are required for both regulatory and commercial purposes. Crucial aspects of the sampling process include taking the sample, the sampling location and witnessing the process.

The importance of a suitably drawn and witnessed representative fuel oil sample cannot be over-emphasised. It forms the basis of all discussion, debate or dispute resolution relating to the bunkering.

Drip Type Bunker Samplers

The most common and economic means of obtaining a representative sample is by using a drip type Bunker Sampler. In back to back tests performed by a major fuel testing laboratory over an extended period, samples obtained by drip samplers were identical to those from more expensive automatic fuel samplers.

How to Select the Correct Size of Drip Type Bunker Sampler






A = Pitch Circle Diameter
B = Nominal Pipe Size
C = Bolt Hole Diameter


Calculation

Pitch Circle Diameter (A) - Bolt Hole Diameter (C) = X

Select the nearest size Bunker Sampler with an outer diameter smaller than X and an inner diameter larger than the Nominal Pipe Size (B).


Example

Pitch Circle Diameter (A) = 290 mm
Bolt Hole Diameter (C) = 23 mm
Nominal Pipe Size (B) = 200 mm

290 (A) - 23 (C) = 267 (X)

Therefore the correct Bunker Sampler would be FG-K1-128-KW (8” Bunker Sampler), which has an outer diameter of 266 mm and an inner diameter of 221 mm. The outer diameter is smaller than X (the space between the flange bolts), yet the inner diameter is larger than the nominal pipe size (B), so that fuel flow is not impeded. See chart below for guidance to Bunker Sampler sizes.

Bunker Sampler Selection Chart

The chart below gives guidance to select the correct Sampler for a range of standard pipe flange sizes. Samplers are manufactured to fit within the bolt ring of standard flange sizes as listed. For other sizes please contact Kittiwake.
