3.9 IMO MARPOL Annex VI


Actions for Compliance with IMO MARPOL Annex VI

With effect from 19th May 2005, IMO MARPOL 73/78 Annex VI on the Prevention of Air Pollution from Ships becomes mandatory for all internationally trading vessels above 400 GT. There are requirements, partly related to the SOx controls, which cover certain aspects related to fuel oil quality and supply arrangements - Regulation 18.

IMO MARPOL Annex VI contains provisions allowing for special "SOx Emission Control Areas" (SECA's) to be established with more stringent controls on sulphur emissions. In these areas, the sulphur content of fuel oil used onboard ships must not exceed 1.5% m/m, alternatively, ships must fit an exhaust gas cleaning system or use other technological methods to limit SOx emissions.

Bunker collection, sampling and storage guidelines are provided in Annex VI and have been defined by MEPC 96(47), which states that:

"A retained sample of all fuel oils as supplied, is drawn at the ships receiving manifold, sealed, signed on behalf of the supplier and the Master or ship's officer in charge of the bunkering operation. The retained sample is to be kept under the ship's control until the subject fuel has been substantially consumed, but in any case for at least 12 months from the date of delivery."

It is important to remember that this sample is to be used solely for determination of compliance with Annex VI of IMO MARPOL 73/78 and cannot be used for any other commercial purposes. However, samples can be drawn at the same time for other purposes.

Summary:

A representative sample is fundamental for all later testing.

Continuous drip manual sampler is the proven method for effective sampling.

The sample must be witnessed by all parties, supplier’s representative as well as recipient/ship.

The point of custody transfer is usually factory or ship’s manifold.

Careful measurements during delivery will produce savings.

Samples should be handled and stored carefully - they may be the only evidence.

IMO MARPOL Annex VI requires you to store the sample for at least 12 months and the Bunker Delivery Receipt for 3 years.
