4.04 LOADING PROCEDURE

The loading of liquid chemicals and petroleum products may take place when the ship’s readiness to commence cargo transfer is verified by the Chief Officer, as per procedure 4.03, Preparation for cargo transfer.

4.04.1 Purpose

This procedure is established to ensure safe and smooth loading operations, in accordance with regulations and requirements by port authorities and terminals, adapted to the specifications and capacities of the ship.


It is the responsibility of the Chief Officer to implement the procedure and to instruct and supervise the Officers and Ratings involved in the operation. The Master shall verify compliance with the procedure.


Essential information is given for may cargoes in the date sheets on board. If for any other cargo – sufficient information relevant to its safe carriage is not available, loading should be refused according to the regulations.

See also procedure 4.07 Precautions when handling liquid chemicals.

The loading shall be performed as follows:

1. Inform and instruct all officers involved in the loading operation, regarding the Cargo Plan and the procedures applying to the operation.

2. If the nature of the cargo so requires, Nitrogen will be supplied from shore. The supply of Nitrogen is made through the cargo piping system and into the designated tanks.

If the nature of the cargo so requires, regular measurements of the 02 content in the tanks shall be made until required tank atmosphere purity is reached.

3. Open up the PV valves to the designated tanks. If a vapour return line is to be used, ensure that it is properly connected and that all system valves between ship and shore are fully opened.



4. Check the communication lines between ship and terminal, and pay special attention to the safety precautions at the manifold during start up and when increasing pressure rates.

5. Open the valves between the manifold and the designated tanks according to the Cargo Plan.

6. Commence loading at slow speed, if possible by free flow.

7. Perform routine check of cargo hoses and flanges. Retighten bolts as necessary.

8. Check receiving tanks, to ensure that the cargo is received according to the Cargo Plan.

9. When approx one foot of cargo is received, discontinue the loading operation, allowing for cargo samples to be collected.

10. Orders to re-commence loading will be given by the Terminal Representative.When re-commencing the loading operation, items 5,6,7,8 shall be observed.

11. Inspect for leakage all overboard discharge outlets and manifold lines not in use.

12. If another liquid chemical product has already been loaded, check for leakage into these tanks by inspecting valves, blind flanges and/or ullage readings. Avoid contamination!

13. Inspect the venting system to ensure that the gas displacement by the incoming cargo are being vented to the atmosphere via the vent stacks.

14. Order a gradual increase in pressure/loading rate till the agreed loading rate has been reached. Maximum pressure must not exceed the ship’s design capacities.

15. Repeat step 5-7 and 10-13 throughout the period of increased pressure/loading rate, till the working pressure has been stabilised over a period of time, and no leakage has been observed.

16. In case of any leakage or contamination, close off the affected area between the leak and the flow of cargo. Use the emergency stop procedure if required.



17. In case of leakage overboard, fire, explosion or other emergency situations which may endanger the ship or involve danger of pollution, execute the emergency stopping procedure. Then give alarm signals and initiate the proper emergency procedures.

18. Initiate and supervise regular control of all elements contained in the Ship/Shore Safety Check List. Discontinue loading operation if deemed necessary on account of safety reasons and take corrective action.

19. Recommence loading according to the Cargo Plan, and top off the tanks at low flow rate to the planned ullage readings.

After topping off individual tanks the Master valves shall be shut to provide two-valve segregation between loaded tank.

Check loaded tanks to ensure that overflows do not occur due to leaking valves or other reasons.

20. Advise the Terminal Representative, in adequate time prior to topping off the final tanks, to reduce the loading rate sufficiently to permit effective control of the flow on board the ship.

When possible, the final topping off operation, shall be carried out by gravity loading.

The ship shall not close all its valves against the flow of cargo, particularly when pumping from the shore installation.

At completion of loading the shore control valves shall be closed before the ship’s valves. Cargo deck lines shall be drained and air blowed/purged with nitrogen as required into a cargo tank to ensure that thermal expansion of the contents of the lines cannot cause leakage or distortion.

21. After the completion of loading, the Duty Officer shall check that all valves in the cargo system are closed, and that all appropriate tank openings are closed and sealed.

22. If necessary a “nitrogen blanket” shall be laid in the designated tanks at the completion of loading. This is executed by supplying Nitrogen under pressure in order to remove eventual 02 remaining in the tank.



23. Cargo samples must be collected as required by the Shippers.

Normally cargo handling shall be carried out on the manifold prior to loading cargo into the tank, and before is discharged past the manifold presentation flange.

4.04.4 CARGO CALCULATION AND LETTERS OF PROTEST

The final intake of cargo is calculated by the chief Officer on the basis of final ullages and temperature readings taken after the completion of loading operation when the tanks are well vented and settled, and specific gravities as verified by the Terminal Representative.

4.06 BALLASTING AND DEBALLASTING PROCEDURE

Ballasting is performed during/or after discharging operations to ensure that the ship maintains sufficient stability; alongside or at sea berth, and to ensure seaworthiness for sea-passages.

Deballasting is performed when loading, alongside or at a sea berth.

It must be ensured that the vessel maintains sufficient stability during the cargo transfer operations.

See: The Ship Loading Manual for stability conditions.

4.06.1 Purpose

This procedure is established to ensure that the ballasting and deballasting operations are performed in compliance with regulations and recommendations in force, adapted to the stability and loadline restrictions of the ship.


It is the responsibility of the Chief Officer to implement the procedure and to instruct and supervise the Officers and Ratings involved in the operations. The Master shall verify compliance with the procedure.

4.06.3 Work performance Ballasting operation.

1. A ballast Plan shall be prepared prior to commencement of ballasting and is to be coordinated with the Cargo Plan with regards to stress, stability and maximum draft.

2. Open the valves to the designated tanks and the ballast sea-valves when the discharging operation is well under way. Commence ballasting by gravity.

3. Check that uncontaminated ballast water is entering the ballast tanks and that the tank venting system is operating.

4. Start the ballast pumps when it is necessary to increase the flow rate.5. Check draft to control that maximum draft restrictions are not

exceeded.

6. Top off the designated ballast tanks to the required level and stop the ballast pumps.

7. Close all valves in the ballast system.

8. Enter the ballast intake in the ballast Log Book.Chapter 4.06 Revision 0 Date 10.03.1998 Page 1 of 3


When rough weather ballast is taken in cargo tanks such tanks shall be cleaned prior to ballasting. After discharging such ballast the cargo tanks have to be washed with fresh water while still wet from salt water.

4.06.4 Deballasting operation

1. A Deballasting Plan shall be prepared prior to commencement of deballasting and is to be coordinated with the Cargo Plan with regard to stress and stability and maximum draft.

2. Open the valves to the designated tanks and the ballast sea-valves and initiate gravity deballasting.

When arriving at a loading port commence deballasting in accordance with local draft regulations.

3. Check the overboard outlets for contaminated water.

4. When gravity deballasting is no longer effective, close the by-pass valves used for gravity deballasting, and open the segregated system valves to the designated tanks and start the ballast pump.

5. Check draft to ensure the maximum draft restrictions are not exceeded by incoming cargo.

6. When drained, stop the ballast pump and close the ballast sea-valves.

7. Perform a check of all ballast-system valves to ensure that they are closed. Close all openings.

8. Take soundings to confirm that the tanks are empty.

9. Enter the ballast discharge in the ballast Log Book.

4.06.5 Verification

The Duty Officer shall supervise the ballasting and deballasting operation, and shall control the quality of his own work, subject to verification by the Chief Officer.

Adherence to the procedure for each ballasting-deballasting operation shall be verified by the use of a checklist.

The completed checklist, Company format 413, shall be filed.

When non-conformance(s) is observed these shall be marked on the checklist and a copy shall be transmitted to TGI.




The ballast Log Book shall contain times, dates and quantities pumped in or out of the specific ballast tanks.

4.06.7 Updating


The Duty Officer is requested to report any disagreement between the procedure and actual requirements to safe and efficient ballasting/deballasting.

The Master to the Technical Manager for approval submits proposed changes of the procedure.



4.07. CARRIAGE OF HAZARDOUS AND NOXIOUS LIQUID SUBSTANCES IN BULK.

Noxious liquid cargoes in bulk shall be handled with special precautions, in compliance with the requirements of:

- IMO, International Code for the construction and equipment forShips carrying dangerous chemicals in bulk, IBC/BCH code.

- IMO Marpol 73/78, Annex II, regulations for the control of pollution by noxious liquid substances in bulk.

- ICS Tanker Safety Guide (chemicals)

4.07.1 Purpose

This procedure is established to outline hazards involved in handling dangerous chemicals in bulk, and precautions to be taken. Further it shall provide reference to regulations, recommendations and publications.

4.07.2 Responsibilities

It is the Master’s responsibility to solicit and review relevant information of the cargo to be loaded, and with the Chief Officer to ascertain that the requirements to handling, and appropriate preventive measures to avoid pollution, are incorporated in the cargo plan.

Further, the Master shall verify that the requirements are complied with, and that the preventative measures are implemented.

4.07.3 Provision and control of information

Prior to shipment the Cargo Owner/Charterer shall provide the Master with full details of the cargo to be carried, including:

- Identification of the substance(s)- Specification of potential hazards related to handling during the

loading, transportation and discharging phases.- Special precautions to be observed.- Recommended emergency actions, for incidents involving personnel,

ship and cargo, and the environment.- Categorisation of the cargo:

- The Master/Chief Officer shall verify information received about cargo category(s).



- If such information is not received, the categorisation must be determined by the Master/Chief Officer, prior to preparation of the cargo plan.

- Noxious liquid substances are categorised in Marpol Annex II, regulation 3 presenting the following four degrees of consequences if discharged to the sea:

- Category A: Major Hazard or serious harm- Category B: Hazard or harm- Category C: Minor hazard or minor harm- Category D: Recognisable or minimal harm

For the full text reference is made to Marpol page 224, and appendices I & II to Annex II. (Consolidated edition 1991).

Preventative measures to avoid pollution shall be applied in proportion to the categorisation of the substance(s) carried, from the most stringent measures to appropriate attention.

4.07.4 Health hazards and precautions

Cargoes may be harmful if the liquid comes in contact with the skin, if their vapours are inhaled or if the liquid is swallowed. The seriousness of the effect depends on both the physical properties of the cargo and on its toxicity or irritant nature.

Absorption of a cargo through the skin depends on the solvent nature of the cargo. If the cargo cannot pass readily through the skin, no skin absorption hazard exists even if the liquid is a poison.

The inhalation hazard of a cargo depends primarily on its volatility. A cargo which is not volatile at normal handling temperatures may not produce sufficient vapour to be dangerous, even if the cargo is inherently poisonous.

Information about the three ways in which a cargo may be harmful, viz. By skin contact, by inhalation or by ingestion, and the precautions necessary when such hazards exist, are given in ICS Tanker Safety Guide (Chemicals) 9.3, 9.4 and 9.5 respectively.

4.07.5 Chemical reactivity hazard and precaution

Special consideration has to be given to the possibility of chemicals undergoing a chemical or physical reaction during cargo handling and transport conditions thereby creating additional hazard.



Three main types of reaction have to be considered:

(a) Self-reaction and reaction with air where only the particular chemical itself is involved in self-reaction.

(b) Reaction as a result of mixing one chemical with another.(c) Reaction as a result of mixing with water.Information regarding above is given in Chapter 10, ICS Tanker Safety Guide (Chemicals).

4.07.6 Requirements to loading, transportation and discharging

The IBC/BCH code primary deals with the fitness of the vessel to carry noxious cargoes, but states in the preamble No. 5 that other important facets of the safe transport of products, such as training, operation, traffic control and handling in port, are or will be examined further by the organisation. (IMO).

Attention is drawn to chapter 16 in the code, related to issues that are operational in nature, and mentioned those other important safety features that are peculiar to chemical tanker operation, comprising requirements as follows:

16.1 Maximum allowable quantity of cargo per tank16.2 Cargo information16.3 Personnel training16.4 Opening of and entry into cargo tanks.16.5 Stowage of cargo samples16.6 Cargoes not to be exposed to heat16.7 Additional operational requirements16.A Additional measures for the protection of the marine environment.

Execution of cargo handling

Cargo operations shall, with due consideration of the information see 4.07.3 and compliance with requirements see 4.07.6 be executed as outlined in procedures Nos. 4.03, 4.04, 4.05 and 4.08 in this manual.


The considerations of information, definition of preventive measures, and incorporation in the cargo plan shall be summarised by the Chief Officer, and the summary shall be filed with the cargo documents related to the specific cargo.



4.08 TANK CLEANING AND GAS FREEING PROCEDURE

Tank cleaning and gas freeing is performed to make the cargo tanks free of flammable and/or harmful vapours and to make them clean enough to load the next cargo.

For chemical liquids reference is also made to “Tank Cleaning Guide” by Dr. A. Verwey, see 8.05 of this Manual, Ship’s Professional Library”.

4.08.1 Purpose

This procedure is established in order to maintain a high degree of safety during tank cleaning and gas freeing, and to ensure that the work is carried out in conformance with regulations and recommendations in force.


It is the responsibility of the Chief officer to implements this procedure and to instruct and supervise the Officers and Ratings involved in the operation. The Master shall verify compliance with the procedure.


It is generally recognised that tank cleaning and gas freeing is the most hazardous period of tanker operations and no short cuts must be tolerated.

Accordingly it is of the utmost importance to adhere to safe procedures, and to exercise the greatest possible care.

The tank cleaning may be divided in several stages, and different methods may be used. A normal process is:--prewash-main wash-fresh water rinsing-gas freeing-drying up-inspection/evaluation-testing

Tank cleaning and gas freeing shall normally be performed during the sea voyage between the port of discharge and the loading port. Sometimes, however, it may be necessary to do the operation at anchorage or alongside.

At sea or at anchorage, the Chief Officer shall observe the safety aspects relevant items in the Safety check List.



Tank cleaning and gas freeing alongside require clearance from the Terminal Representative, and the Ship/Shore Safety CheckList remains fully in force.

The toxic effects of vapours and liquids from chemical cargoes during this operation cannot be overemphasised, and must be impressed on all concerned.

After discharging the cargo tanks atmospheres are a mixture of inert (nitrogen) and vapour from the cargo.

To eliminate the possibility of an explosion during washing it is necessary to eliminate all sources of ignition. Therefore care must be taken to eliminate electro-static ignition,by the earthing of washing machines and recirculation of cleaning-water.

Water from tank cleaning operation containing cargo residues shall not be mixed with slops which are not compatible.

A few cargo require other media for washing than water. Further information about these is to be found on board.

4.08.4 Tank cleaning

1. Instruct officers and Ratings involved in the operation about the Tank Cleaning Plan.

2. Oxygen analysers shall be recently calibrated and inspected/tested prior to use.

3. Prior to initiating the tank cleaning, each tank to be washed shall be analysed in order to determine the oxygen level.Measurements shall be taken at least at a point 1m below the deck and at the middle level of the ullage space. At neither of these locations shall it exceed 8 percent of volume (subject to local regulations).

4. Order the engine room to prepare for delivery of cleaning water to the selected temperature, and to prepare the cargo pump(s) for operation.

5. Open all valves from the designated tanks (s) via the pump (s) and into the tank chosen for slops.

6. Open all valves in the cleaning system to the fixed cleaning units in the designated tank(s).

7. Check that water is received and that the cleaning units rotate.

8. Start the cargo pump with adequate revolutions to keep the tank bilges drained.



9. Check that the designated tanks are drained properly. Avoid build-up of wash water.

10. Check that the washwater is pumped into the slop tank(s). Do not recirculate the washwater.

11. Keep the washing routine running for the time necessary to achieve the required result.

12. Monitor the oxygen level for each tank to be washed and the tank pressure of the inert gas being delivered.

13. Stop water supply to the cleaning unit, drain out all water in the tank and stop the cargo pump.

14. Commence the procedure for the next tanks to be cleaned, till satisfactory results are achieved.

15. After completion of tank cleaning and gas freeing the tanks must be drained of all remaining water by means of the water ejector “pump”.

This particularly is required prior to loading gasoline, naphta and jetfuel, as the mixing of these fluids with water generates electrical charges.

16. The slop must be pumped ashore at the loading port.

When the cargo tanks have been used as slop tanks, the content must be pumped ashore prior to loading, and the cargo tanks used must be tankwashed.

The procedure for these operations must be planned and agreed with the shore installation prior to berthing.

4.08.5 Gas Freeing 1. Instruct officers and Ratings involved in the operation about the gas

freeing plan.2. Purge the tank by using inert gas until the hydrocarbon content is 2%

or less by volume.

A suitable meter, recently calibrated and checked shall be used to measure the percentage of hydrocarbon and/or toxic gas.

When using inert gas for the purpose of purging it should be set for maximum capacity to provide maximum turbulence with the tank.

Chapter 4.08 Revision 0 Date 10.03.1998 Page 3 0f 4


3. The ships ventilation fans/system shall be used for venting of cargo tanks.

4. If an internal inspection of the tank is required to ascertain the result of the tank cleaning and gas freeing operation, attention is drawn to the Entry in to Enclosed Spaces procedure.

5. Commence the procedure for the next tanks to be gas-freed, till satisfactory results are achieved.

4.08.6 Verification After the completion of tank cleaning and gas freeing the Chief officer shall perform an inspection of the cargo tanks, to ensure that the tank washing meets the standard required for the next intake of cargo.

He should also perform analyses of the tank atmosphere by taking measurements related to gas density and toxicity when considered necessary.

Adherence to the procedure for each tank cleaning and gas freeing operation shall be verified by the use of a checklist. The completed report/checklist, Company format no. 412, shall be filed for each operation.

4.08.7 Documentation All details regarding tank cleaning and gas freeing must be entered in the Deck log book and the Oil Records logbook.

4.08.8 Updating This procedure is subject to change caused by new regulations, recommendations or operational requirements.

The Chief Officer shall report any disagreement between the procedure and actual requirements to safe and efficient tank cleaning and gas freeing.Proposed changes of the procedure are transmitted to the Technical Manager for approval.

4.10 TREATMENT OF SLOPS AND CARGO/WATER MIX

During and upon completion of tank-cleaning, line flushing or other cleaning operations which is performed to remove cargo residues, some mixture of cargo and water will be transferred to the slop tank (s).

The use of cargo tanks for ballasting purposes in order to maintain sufficient stability and/or in heavy weather may also generate amounts of dirty ballast water, which has to be discharged.

4.10.1 Purpose

This procedure shall ensure that treatment and discharging of slops is carried out safely and in conformance with regulations and recommendations in force.


It is the responsibility of the Chief Officer/chief Engineer to implement the procedure and to instruct and supervise the Officers and Ratings involved in the operation. The Master shall verify compliance with the procedure.

4.10.3 Work Performance

Under normal circumstances cargo residues and cargo/water mixtures shall be delivered to a receiving Terminal, and this is mandatory for cargo residues/slops of cargo category A.

However, it may be discharged overboard if deemed necessary, but only in dedicated areas.

Any discharge overboard shall be in accordance with:

-Marpol 73/78, Annex II

-The Norwegian Ship Control Legislation Section 21, Part 2, Reg. 1.

See: 10. 03. 4, Sediments and wastes.

4.10.4 Discharge from slop tank

Residues retained on board in slop tank, including those from cargo pump-room bilges, which contain a Category A substance, or within a special area either a Category A or a Category B substance, shall be discharged to a reception facility in accordance with the provisions of regulations of Annex II.

With respect to Category D substances, a tank which has been unloaded shall either be washed, and the resulting tank washings be discharged to a reception



facility, or the remaining residues in the tank shall be diluted and discharged into the sea in accordance with the provisions of regulations of Annex II.

4.10.5 Slops

- Slops which are retained on board shall be kept pressurised by good quality inert gas, and positively segregated from the cargo holds and cargo piping system.Slop tanks and openings shall be securely battened down.

Retainment of slops are subject to local port regulations, when carrying bulk cargoes.

- In order to segregate the water from the cargo residues, ample settling time shall be allowed, within the designated slop tank (s).

Depending upon the type of cargo and the motion of the ship the time required for cargo and water to segregate will vary. Normally 36 hours or more should be allowed.

Further segregation is achieved by draining the cargo/water mixture, upon the first stage of settling, to the second slop tank, again allowing for settling.

- Prior to discharge of the slop tank contents, the following operations shall be executed: Cargo lines which are to be used for discharge of slop shall be

properly flushed with water. An accurate interface and ullage reading, using a cargo/water

interface detector, must be taken to determine the depth of the oil layer.

The cargo content monitor shall be recently calibrated and checked operational.

- Discharge the slop tank through the monitored overboard discharge line, until a water depth of approx 20% of the tank is reached. Agitation of the contents in the slop tank must be kept to a minimum.

- Stop the pump and perform a cargo/water interface and ullage rating. Re-calculate the remaining water depth.

- Re-commence discharging until the predetermined water depth is reached.

The pumping rate shall at this state be reduced and the cargo content monitor readings shall be carefully monitored.



- If cargo should occur before the predetermined water depth is reached, pumping shall be stopped immediately, and further settling of the slop shall be allowed.

- Re-commence discharging until the trend of the cargo content monitor indicates that the interface is reached, and stop the discharge immediately.

- Perform flushing of the used lines and pumps, to remove contained traces of cargo.

- After proper discharge of the water content in the slop tank the cargo residues may be retained in the slop tank, as described or be transferred to a cargo tank for load on top, depending upon the compatibility with the next cargo. If preferred or required the remaining slop shall be delivered ashore.

4.10.6 Engine room bilge water

Bilge water from the engine room shall be separated/filtered through the oily water separator or filtering equipment, ensuring an oil content of 15 PPM or less, prior to discharge overboard.

Oil residues will be transferred to the sludge tank (s) for later transfer ashore, or burned in an incinerator.
