multi-purpose fire fighting foam effective against many water soluble cargoes This is the most commonly used type of fire fighting foam on chemical tankers ♦ Anaesthesia A total loss of feeling and consciousness, or the loss of power or feeling over a limited area of skin ♦ Anaesthetics Chemicals which produce anaesthesia ♦ Aqueous Indicating that the compound is in solution in water ♦ Asphyxia The condition arising when the blood is deprived of an adequate supply of oxygen, so that loss of consciousness may follow ♦ Asphyxiant A gas or vapour, which may or may not have toxic properties, which when present in sufficient concentrations excludes oxygen and leads to asphyxia ♦ Audit A method of checking that procedures (as written down) are being followed, and that any amendments required have been carried out to maintain a quality service ♦ Auto-ignition Temperature (Autogenous Ignition Temperature; Ignition Temperature) The lowest temperature to which a solid, liquid or gas

Experience Factor (Load) 14.3 GENERAL Transportation of chemicals by tankers is usually accompanied by considerable documentation Documentation can be even greater when trading to and from less developed countries The vessel’s management is presented with a great deal of documentation from parties to the cargo, authorities, etc Furthermore vessel’s management must also issues papers serving to record evidence, claims etc Cargo is bought and sold in various units of measurement These may be Barrels (Bbls) at 60F, Cubic metres (M3) @ 15C, Metric Tonnes in Vacuum, Metric Tonnes in Air and Long tons in Air CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO CALCULATI ON Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 10 Other conventions of measurement exist, and the purpose of this section is to show how the vessel may deal with any system of measurement without difficulty 14.4 ASTM TABLES In 1980, the American Society for Testing and Materials (ASTM) together with the London Institute of Petroleum (IP) and the American Petroleum Institute (API), introduced the new API/ ASTM-IP Petroleum Measurement Tables (further ASTM tables) Presently the set of ASTM tables consists of 14 volumes however only a few tables are required for onboard cargo calculations The following is the list of ASTM volumes (with description of required tables) each vessel should carry on board: For tankers carrying Petroleum Products: • • • • • • Volume II (Tables 5B and 6B) Table 6B to be used for petroleum Products correction of volume to 60º F against API Gravity at 60º F (American Measurement System) Volume VIII (Tables 53B and 54B) Table 54B to be used for Petroleum Products correction of volume to 15º C against Density at 15º C (Metric Measurement System) Volume XI/ XII (Tables 1-4, 8-14 and 21, 22, 26-31, 33, 34, 51, 52, 56-58) Tables for conversion between various Volume and Density Measures These sets of books together with ship’s Ullage Tables or Sounding tables provide everything required for calculating the quantities of oil cargoes on board the vessel 14.5 DENSI TY, RELATI VE DENSI TY AND API 14.5.1 Density Density is by definition measured in a vacuum at 15C Density x volume (M³ ) gives metric tonnes in vacuum Density – 0.0011 is known as “density in air” For example: 1000M³ at 15C of density 0.8560 is 856 metric tonnes (MT) in vacuum or 854.9 MT in air Use tables 54A or B in volumes VII and VIII 14.5.2 Relative Density 15/ Relative density 15/ is the density of oil at 15C/ density of fresh water at 4C Relative density 15/ can be treated exactly the same way as density at 15C as it is almost the same Use table 54A or B in volumes VII or VIII or convert to API using table in volume XI/ XII CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO CALCULATI ON Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 10 14.5.3 Relative Density 60/ 60 ( SG) Relative density 60/ 60 is the density of cargo at 60F/ density of fresh water at 60F Convert this to density at 15C, or API using table in volume XI/ XII 14.6 VOLUME REDUCTI ON TO STANDARD TEMPERATURE There are several standard temperatures in use throughout the industry It is the Company policy that, except where tank calibrations are only in barrels, calculations of cargo quantity will be done using density at 15C and cubic metres as a volume measure If the density is given at 20C, as in Brazil or Rumania, it should be converted to 15C in the following way Product density @ 20C = 0.8764 Table 53B, Volume VIII, page 209 Call 20C “observed temperature” Corresponding density @ 15C is 0.8798 Proceed with calculation using density @ 15C Reduce the volume to 15C with table 54B, or 60F with table 6B as appropriate 14.7 ULLAGE REPORTS On completion of loading and prior to commencement of discharge operations the Chief Officer together with the surveyor will check the ullage and the temperature of the relevant tanks These two parameters are the basis for the cargo calculation and they are to be recorded in the “Ullage Report Form” With heated cargoes, great care must be taken to establish the correct average temperature in each tank This can only be done with electronic probe thermometers Some cargoes however, will block the sensor of the thermometer If this occurs, glass thermometers are to be used in preference to blocking up all the ship’s electronic thermometers If glass thermometers have been used, a note are to be made on the Ullage Report Form Water dips can successfully be taken in almost any heated cargo, if the sounding rod is left on the bottom for a minute, and gently worked up and down Kolor Kut water finding paste should be used if possible, in preference to Vecom water finding paste as the Vecom paste tends to change colour in contact with suspended traces of water in the cargo, and may cause great errors in the recorded free water quantity 14.8 SHI P’S EXPERI ENCE FACTOR ( SEF OR VEF) Surveyors at a load port must always be given the information to calculate the Ship’s Experience Factor or Vessel Experience Factor CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO CALCULATI ON Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 10 14.9 ( “ROUGH”) PORT/ CARGO LOG The “rough”, (or working) cargo log must be kept by the officers on duty to document the loading and discharging operations It serves to record data as a basis for the ‘Statement of Facts’ as well as all circumstances and events relevant to any dispute with the parties to the cargo The rough cargo log is a very important document of proof in case of disagreements between the parties involved The following entries are the minimum necessary: • Hose connected • Purging times • Foot sample/ line sample • Loading/ discharging times • Loading/ discharging pressures (every ẵ hour) For heated cargoes; temperatures • Blanketing times • Stoppages + reason • Special circumstances and events • Other relevant information AS THE CARGO LOG MAY BE USED IN ARBITRATION OR OTHER LEGAL ACTION THE ENTRIES SHOULD BE LEGIBLE, CHRONOLOGICAL AND NEAT 14.10 NOTI CE OF READI NESS ( NOR) A Notice of Readiness (NOR) must always be provided when a vessel arrives at the port of destination Whether the berth is occupied or not, whether the vessel is alongside or not, on arrival at the port of destination the Master must present the NOR on the appropriate form If it is not possible to berth, for whatever reason and the vessel has to wait on the roads, the NOR must be tendered by telex, fax, e-mail or by telephone In the latter case this must be followed by written confirmation to the agency, requesting them to provide it to the Receivers, Charterers, Terminal etc Significant for the ‘time counting’ is the time the NOR has been tendered- and not the acceptance of the notice The only time when NOR is not effective is when repairs have to be carried out, before the vessel can load / discharge In such case NOR should be given immediately after the repairs have been completed Separate NOR must be tendered for each Shipper or Receiver When a parcel is completed at a particular berth and the next berth involving a different Shipper or Receiver is occupied, then the NOR must be tendered when the hose(s) is disconnected, at the berth where the vessel is moored CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO CALCULATI ON Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 10 At the load port the NOR must have the amount of cargo for each parcel that the vessel can load For example 1050 mts, but never write 1050 mts more or less owners option or similar phrases Always state the maximum quantity the vessel can take within the quantity option agreed in the fixture on the NOR At the discharge port the NOR must include the amount of cargo according to the B/ L 14.11 BI LL OF LADI NG, B/ L The B/ L is presented to the Master by the Shipper or the Agent in the port of loading, usually three originals and one set of copies The weight of the cargo loaded is determined by ship and shore figures Usually the shore figures are used on the B/ L The following items have to be checked carefully before the B/ L is signed: • Cargo destination and weight • Bill of Lading number • Date of issue: always the final loading date • Date of charter party, as indicated in the voyage orders • Information regarding ship: name, nationality, name Master, etc • Method of payment of freight Freight as per c/ p Freight prepaid Collect freight Other • Correct port of discharge • Cargo commingling Clause The three original Bs/ L must be signed personally by the Master and not by a rubber stamp All other Bs/ L prepared, apart from the agreed originals are to be stamped “Copy – Not negotiable” A blank B/ L must never be signed In special circumstances – by prior agreement from the Owners – the Ship’s Agent may be authorised to sign the completed Bill on behalf of the Master In this case clear instructions must be given by the Master to the Agent on the procedure to be followed On all occasions however the Agent before signing the B/ L must contact the Master concerned who in turn will advise if a clean B/ L may signed or endorsed with the quantity in dispute or a Letter of Protest issued in lieu of clausing the Bill of Lading If the Ship’s figures differ more than 0.5% from the Bill of lading figure, and clausing of the Bill of Lading is not acceptable to the Shipper, the Master should contact the management office for further instructions CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO CALCULATI ON Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 10 As soon as agreement is reached on all points, all Bs/ l are to be signed by the Master Usually the Master will be provided with an original B/ L, sometimes only a copy The departure telex/ e-mail to the management office should include the type of Bs/ l remaining on board A Bill of Lading endorsed with “Freight Prepaid” should never be signed without prior approval from the Owners or management office The original Bill of Lading (or Delivery Note) covering the cargo, duly endorsed by Consignee or Receiver has to be presented to the Master prior commencement of discharge In the port of loading the Master is often given an original B/ L for the receiver of the cargo If the Master is able to determine beyond any doubt the identity of the Receiver in the port of discharge, he may give him the B/ L in exchange for a receipt Otherwise, the original B/ L is to be given to the Agent in the port of discharge in exchange for a receipt in which he is obligated to give the cargo to its rightful Receiver If an original Bill of Lading can not be presented on arrival of the vessel the management office is to be informed immediately and the Master should act according to the instructions given A solution could be the discharge of the cargo against the issue of a ‘Letter of Indemnity’ (LOI), provided the Owners have agreed to it In such a letter the Charterer or Shipper guarantees to hold the vessel/ owners free of responsibility for the consequences for delivering the cargo without the availability of an original B/ L Another possibility which may be considered, after approval from Owners, is for the cargo to be discharged into customs bonded storage, from which it will only be released to Receivers after the original B/ L is presented or LOI received 14.12 LETTERS OF PROTEST In order to ensure Owners claims against parties involved or to annul any claims against Owners the following protest are to be issued in the English language under certain conditions: • • • • • 14.12.1 Difference Protest Deadfreight Protest Temperature Protest Low loading or discharging Rate Protest Exceeding of maximum agreed quantity Difference Protest Upon presentation of the B/ L, the cargo weight indicated in the Bill of Lading (Shore figures) is to be compared with the ship’s ullage measurement (Ship’s figures) In case of any deviation of B/ L weight from the ships figures, a difference protest is to be issued and addressed to the Shipper The protest is usually signed ‘for receipt only’ If the Shipper is not available on board to receive the protest, the Agent has to be given the protest in exchange for a receipt stating his obligation to hand it over to the Shipper When the difference Bill of Lading- Ship’s figures in the discharge port is more than 0.5% the surveyor will usually address an appropriate protest to the ship This protest should always be signed CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO

without consultation with the management office 14.12.2 Deadfreight Protest This protest is the basis for Owners deadfreight claim against the Charterers, in the event that the shippers are unable to supply the quantity nominated in the Notice of Readiness It is important that the form is filled in completely and delivered to the Shippers via the Agent as soon as it is known that the nominated quantity is not / will not be loaded 14.12.3 Temperature Protest Cargo loading temperature or temperature margins are agreed for cargoes requiring heating If the temperature deviates appreciably from the agreed levels (usually + / - 10% of the allowed temperature) a ‘temperature protest’ is to be issued against the Shipper If the maximum temperature agreed to is exceeded (e.g for phenol) even minimum excess temperature can not be accepted, depending on the product and conditions of stowage A ‘temperature protest’ is to be issued The management office is to be kept informed The Receivers will usually protest when the cargo temperature is determined as too low or too high by the surveyor Discharge temperatures of cargoes –MARPOL category ‘B’ and ‘C’ should be at least or 10°C above the melting point of the product in each case, but always within the heating orders as stipulated by the Shipper and/ or Owners so as to avoid the prewash obligation In case of cargoes requiring heating, the heating orders of the Shipper or Owners must be followed to avoid protests and delays in the port of discharge Note that overheating can damage some cargoes (Phenol, HMD) 14.12.4 Low loading or discharging rate protest Depending on the total time for loading, a suitable protest is to be directed to the Shipper if the loading rate is much too slow Some charter parties have a minimum loading rate In this case the operator will inform you regarding the minimum loading rate A discharge rate (m3/ h) is normally agreed in the charter party The Receiver will lodge a ‘discharge rate protest’, if the actual rate seems too slow to him All remarks have to be entered by the Master in the protest that could improve the position of Owners in a possible claim Such as, but not limited to the following: • Back pressure too high • Length of the landline • Small diameter of the landline • Difference in height between ship and land tank • Product properties(viscosity) • In case of heated cargoes: insulation of land line CHEMI CAL TANKER MANUAL SECTI ON 14 – DOCUMENTATI ON AND CARGO CALCULATI ON • 14.12.5 Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 10

exceeded, the management office must be informed immediately that necessary steps can be taken The following solutions are feasible: • Protest • Pumping back the excess cargo 14.13 STATEMENT OF FACTS On the ‘Statement of facts’ all relevant facts and times concerning loading / discharging are to be recorded The statement is the basis for laytime counting and has to be signed by the Shipper’s - or Receiver’s representative (usually the Loading Master) the Master and the Agent A completely signed ‘Statement of facts’ is effective evidence It is important that the statement contains all conditions and events that have a positive influence on time counting A ‘Statement of facts’ must contain, depending on the situation, the following data, events or conditions, stating local times: •

16.1 REFERENCE PUBLI CATI ONS The following reference publications are to be read in conjunction with this section Publication Location US Coastguard 46 CFR part 150 Master 16.2 EXPLANATI ON OF CARGO COMPATI BI LI TY CHART DEFINITION OF HAZARDOUS REACTION - As a first approximation, a mixture of two cargoes is considered hazardous when, under specified condition, the temperature rise of the mixture exceeds 25o C or a gas is evolved It is possible for the reaction of two cargoes to produce a product that is significantly more flammable or toxic than the original cargoes even though the reaction is non-hazardous from temperature or pressure considerations Chart format - There are different degrees of reactivity among the various cargoes Many of them are relatively non-reactive: For example, aromatic hydrocarbons or paraffins Others will form hazardous combinations with many groups: For example, the inorganic acids The cargo groups in the compatibility chart are separated into two categories: through 22 are "Reactive Groups" and 30 through 43 are "Cargo Groups" Left unassigned and available for future expansion are Groups 23 through 29 and those past 43 Reactive Groups contain products which are chemically the most reactive; dangerous combinations may result between members of different Reactive Groups and between members of Reactive Groups and Cargo Groups Products assigned to Cargo Groups, however, are much less reactive; dangerous combinations involving these can be formed only with members of certain Reactive Groups Cargo Groups not react hazardously with one another 16.3 USI NG THE COMPATABI LI TY CHART The following procedure explains how the compatibility chart should be used to find compatibility information: Determine the group numbers of the two cargoes by referring to the alphabetical listing of cargoes and the corresponding groups Many cargoes are listed under their parent names: unless otherwise indicated, isomers or mixtures of isomers of a particular cargo are assigned to the same group For example, to find the group number for Isobutyl Alcohol, look under the parent name Butyl Alcohol Similarly, the group number for para-Xylene is found under the entry Xylene If a cargo cannot be found in the listing, contact the Coast Guard for a group determination (see CFR § 150.140) CHEMI CAL TANKER MANUAL SECTI ON 16 – CARGO COMPATABI LI TY Document Number Section Revision Number Page Number : : : VMS/ CHM/ 01 01 of 2 I f both group numbers are between 30 and 43 inclusive, the products are compatible and the chart need not be used If both group numbers not fall between 30 and 43 inclusive, locate one of the numbers on the left of the chart (Cargo Groups) and the other across the top (Reactive Groups) [ Note that if a group number is between 30 and 43, it can only be found on the left side of the chart] The box formed by the intersection of the column and row containing the two numbers will contain one of the following: (a) Blank - The two cargoes are compatible (b) "X" - The two cargoes are not compatible [ Note that reactivity may vary among the group members Note if the products in question are referenced by a footnote which indicates that exceptions exist, then refer to in Appendix I Unless the combination is specifically mentioned in Appendix I, it is compatible 16.4 COMPATABI LI TY CHART Please refer to
