2 01 April2011 SCOPEThis PROJECT STANDARDS and Specificationscovers minimum requirements forprocess design and engineering of loading and unloading facilities for roadTankers in OGP should be noted that the scope of this Standard is limited toliquid applicationsand road tankers only. Furthermore in this manual the unloading part is limited toprobable discharges of the products remaining in the tankers that arrive manual forms part of a series that may be developed ultimately to embraceall facilities connected with bulk loading and unloading of road vehicles, rail tankwagon and on-shore facilities for loading /discharging of water bore this Standard the following dated and undated STANDARDS /codes arereferred to.

6 For this reason, the designs shown includefeatures which will notbe necessary in all situations; and when new facilities are planned it isrecommended that the simplest facilities that will efficiently perform the fillingoperation should be constructed. These requirements can also be used forthe modernization and/or extension of existing loading facilities for the yearly average loading capacity, the size of tanker and loadingassembly may be fixed and pump capacity will be should be noted that in case there is freedom in tanker size and/or loadingassembly then economical evaluation shall be considered for such facilities in the context of the overall distribution systemThe importance of bulk vehicle loading facilities as part of the total distributioncomplex must be fully realized when plans are made for the construction ofnew facilities, or the modernization and extension of existing arrangements.

7 ItKLM TechnologyGroupProject Engineering StandardPROCESS DESIGN OF LOADINGAND UNLOADING FACILITIESFOR road TANKERS( PROJECT STANDARDS ANDSPECIFICATIONS)Page5of43 Rev: 01 April2011is therefore necessary to examine the operation of the distribution system inorderto optimize both its efficiency and the size of the loading facilities. Thelatter are an integral part of the distribution system and should not be studiedin isolation; changes in the system and/or operating procedures can have aconsiderable effect upon vehicle loading requirements. In this context theobjective must be to optimize the number of loading bays, and productloading spouts per bay, in relation to the overall distribution system, capitalinvestment and operating , the cost of own and Contractor s vehicles should be assessed for thetime spent (vehicle standing charges) while:-Queuing for a loading bay;-Waiting for a loading arm while in the bay;-Being loaded in the , for existing installations the traffic flowmust be studied to establishthe present arrival patterns of vehicles at the loading facilities and hence thepeak loading periods.

8 The types of delivery such as urban, country, and overlong distances, will influence arrival of simple methods planning techniques to these operations willshow whether efficiency can be improved by changes in:-Working hours;-Shift patterns;-Staggered starting times;-Night loading ;-Dispatching and delivery systems;The objective being to improve utilization of existing facilities and of theexisting road transport new installations the above information may not be available. In suchcases an operational system must be established in which the various factorsmentioned are carefully considered in relation to practice in the local industry,and in consultation with the is the policy of OGP industries to conduct their activities in such a waythat proper regard is paid to the conservation of the notonly means compliance with the requirements of the relevant legislation,but also constructive measures for the protection of the environment,particularly in respect of avoidance containment of TechnologyGroupProject Engineering StandardPROCESS DESIGN OF LOADINGAND UNLOADING FACILITIESFOR road TANKERS( PROJECT STANDARDS ANDSPECIFICATIONS)Page6of43 Rev.

9 Recovery systemThe recovery of product vapors such as gasoline is of interest foreconomic, safety and environmental reasons. In most locations wherebulk lorries are loaded, the total gasoline vapor emissions have not beenconsidered a significant factor affecting the quality of the localenvironment. Nevertheless, at the design stage, system should bereviewed to see if it becomes necessary to install a vapor collectionsystem return line for poisonous, hazardous and high vapor pressureproducts. [RVP > bar (abs)]In addition, it isnot safe to assume that the presence of a vapor recoverysystem will ensure a safe atmosphere within the tank truck different vapor pressure products are being loaded using a commonvapor recovery system, a flammable atmosphere may be introduced intothe compartments.

10 Such systems should be carefully reviewed todetermine whether this hazard is significant at the particular , it is essential to minimize the generation, and hence theemission of vapors during loading by eliminating the free fall of volatileproducts and reducing jetting and areas where action has been required by National authorities tominimize vapor emissions at loading facilities, bulk vehicles may have tobe filled with a closed vapor system; this entails the following modificationsto loading arrangements:i)Top loadingAs the majority of loading facilities in service are top loading , the bestsolution would be to replace (or modify) the existing loading arms sothat when volatile productsare loaded, the manhole is sealed andvapors are diverted into a vapor return system.
