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