Our Bunker Fuel Drip Samplers are as Accurate as Automatic Fuel Samplers
The most common and economic means of obtaining a representative bunker fuel sample is by using a drip / line type sampler. In back to back tests performed by a major fuel testing laboratory over an extended period, bunker fuel samples obtained by drip / line samplers were identical to those from more expensive automatic fuel samplers. There seems to be no justification for the very considerable extra expense involved in automatic bunker fuel samplers, manufacturers’ claims not withstanding.
Kittiwake drip / line bunker fuel samplers will be found on thousands of ships worldwide and are;
- GL & Lloyds Register approved with certificate numbers etched on drip / line sampler
- GL Certified for MARPOL compliance
- Manufactured under strict ISO 9001:2000 quality assurance standards with complete traceability back to the raw steel
- IMO MARPOL 73/78 Annex VI compliant - helps you stay within the legal requirements for bunker fuel sampling.
- Lightweight and very easy to install - obtaining a representative bunker fuel sample is quick and easy.
- Simple to install on all common flange standards between 2" and 14"
- Complete with bunker fuel sampler Joint Rings.

How to Select the Correct Size of Drip Type Bunker Sampler
Click the images above for large diagrams to help with the following calculations.
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.

Sampler Sizes
The chart above gives you guidance in selecting 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.
