Pre-test sampling
When we are appointed in advance of physical bunker delivery at time of barge loading, we are able to

1. contact bunker fuel supplier, who present the better shore tank quality in
   case extra supervision to avoid quality deviations
2. contact Loading Master at any terminal that we are appointed for barge sampling.
3. contact Barge Captain in order to be on time at physical loading
4. barge loading samples are available immediate after loading which allows us at
   least a time for sample transport and sample testing, whilst barge finalise its
   documentation with Loading Master plus sailing time of barge to come alongside
   for bunker fuel supply

Pre-test analysis:
We are able to test on 24 hrs a day basis within 2.5 hours time for the following parameters:

• Density @ 50°C / density @ 15°C
• Viscosity @ 50°C / viscosity @ 100°C
• Water by Karl Fischer
• Flash Point
• Sulphur
• Existent Sediment by Hot Filtration
• Vanadium

A selection of parameters is your choice, but at least a minimum variable parameters needs
to be verified or certified as density - viscosity - sulphur.
A different selection can be made if barge has loaded from a refinery or at an independent
storage company. Please bear in mind that shore tank quality is certified, not the multi purpose shore
line contents and partly shore tank. Quality is not guaranteed for major shorelines.

Barge measurement:
We measure every barge - all tanks and measurement prior start of delivery will
be signed by parties concerned , before ever starting pumping as an agreement,
avoiding all discussion afterwards.
Measurement at open is binding.

Our attendance will:

• guarantee that barge pumps off up to unpumpables
• each regular ROB (unpumpables) are know by us by regular practical experiences in the
  ARA ports.

We take all dips - ROB - Remaining On Board - and Barge Captain drains its tanks to ROB quantities as unpumpables.
Measurement at close is binding.

The net result between open & close is the binding supplied quantity.

Seagoing vessel measurement:
Pending on the job description which can vary from vessel to vessel,
which can vary by supplier and by port,
we certify open en close readings as reference.
It allows:

• 100 % assistance to Chief Engineer
• practical training to Chief Engineer and its staff
• correct measurement open and close for barge and seagoing vessel
• one set of samples coordination and reporting, avoiding different samples for different
  parties concerned.
• extra sampling for testing before vessel sails.

On hire and off hire survey:
We perform on regular basis on hire of off hire survey, appointed by owners and / or charterers.

Final analysis:
We analyse acc. ISO 8217 - latest version within 24 hours.

Extra survey:

On spot basis we control and advise:

• potential de-bunkering
• physical de-bunkering, including documentation
• free water tank by tank
• spot sampling and testing at any place with Chief Engineer
• independent quantity discrepancies between barge and seagoing vessel

Extra analysis besides regular ISO 8217

We test regular for parameters which has potential caused severe damage to the fuel. In close coordination with practise as experienced by Chief Engineer and proper sampling we investigate various uncommon practises.

Bunker fuel components, known as nonconforming fuel leads to conforming fuel as to ISO 8217 standard

Nonconforming fuel advised limits acc. Governmental Regulation by law:

Nonconforming fuel advised limits acc. Inpechem Inspectors:

Conforming fuels to ISO 8217 needs additional guarantees, not necessary to be
tested:
