Security sealed during sampling toprevent tamp~ring FQT SamPling EquiPment Upon formalisation of an FQT agreement, each participating 'vessel is provided with a Sampling Kit containing detailed programme and sufficient sample bottles for 10 l;mnkerings. These bottles are specially made of high density polypropylene (HDPE) and are complete with bottle plugs, security seals, bottle labels, des- patch cartons and a comprehensive programme manual. Custody Transfer SamPling DNVPS advocates that there should be only one single official sampling point and this is at the point of custody transfer, which is the point where the product changes hands from the deliverer to the receiver. The custody transfer point in this instance is the interface between the ship's bunker manifold flange and the bunker hose flange. A sampling device should be installed at this location for taking a continuous drip sample throughout the whole dura- tion of the bunkering. Important Note It is a common practice for the supplier's representative to ask the Chief Engineer to sign sample labels in advance of bunkering. This practice of pre-signing the sample label must be avoided as it will put you in a legally disadvantageous position if the labels are misused. If offered a sample by the supplier where the contents were not taken at the point of custody transfer or where sampling was not witnessed, it is important to sign 'For receipt only, source unknown.' DNVPS has designed a line sampler which makes sampling very con- venient for the shipboard staff. This is available on order. Continuous drip samPling at custody transfer point The one-litre sample bottles are sealed, labelled and signed by all parties present. One sample is offered to the supplier and one retained on board the ship for safe keeping in case further testing is required. In some instances, the charterer and the shipowner may both be in the FQT programme and may require samples to be tested separately. The additional two samples are intended for this purpose. Details of sample preparation and documentation are contained in the Manual provided in each kit. It is important to ensure that a proper sampling device is used so that a representative sample can be taken during bunkering. A representative sample is essential to ensure that the DNVPS analysis results and technical advice provided to the vessel are valid and useful.
