1978 Protocol Relating to the 1973 International Convention for the Prevention of Pollution from Ships

Appendix II Training for Persons Intended to Assume Overall Charge of Crude Oil Washing

Introduction

Any required training shall be by supervised instruction, conducted in a shore-based facility or aboard a suitably equipped ship having training facilities and instructors for this purpose, dealing with the principles involved and the application of these principles to ship operation.

In drawing up an Administration-approved syllabus of training, the Specifications for the Design, Operation and Control of Crude Oil Washing Systems of tankers adopted by the Conference shall be taken into account.

• 
  Bottom washing;
  
• 
  Trim requirements;
  
• 
  Methods of bleeding off from the cargo discharge;
  
• 
  Maintenance of required washing fluid pressure;
  
• 
  Washing at sea between discharge ports;
  
• 
  Recirculatory washing;
  
• 
  Relative priorities and requirements for the departure ballast tanks, arrival ballast tanks and cargo only tanks;
  

2. 
   Equipment and design
   

1. 
   Location of washing machines;
   
2.

  Characteristics;
  
• 
  Features of construction;
  
• 
  Operating parameters;
  

3. 
   Drive units;
   
4. 
   Washing fluid supply and distribution systems;
   
5. 
   Stripping systems;
   
6. 
   Means of sounding tanks;
   
7. 
   Inert gas requirements.
   

3. 
   Generalized crude oil washing procedures
   

1. 
   Traditional pipeline ship/free flow ship/partial free flow ship;
   
2. 
   Single/multi parcel cargoes;
   
3. 
   Optimization of procedure to wash with minimum extra berth time;
   
4. 
   Ballasting for departure with various ship and pipeline configurations;
   
5. 
   Procedure for washing at sea between discharge ports.
   

4. 
   Associated procedure
   

1. 
   Means for minimizing residues on board
   

• 
  Stripping of cargo tanks;
  
• 
  Draining and stripping of cargo lines;
  
• 
  Final discharge of cargo ashore;
  

2. 
   Water rinsing of arrival ballast tanks;
   
3. 
   Filling and ultimate discharge of arrival ballast;
   
4. 
   Discharge of departure ballast;
   
5. 
   Build-up and decanting of slop tank;
   
6. 
   Requirements of Regulation 9 of Annex I of the MARPOL Protocol;
   
7. 
   Avoidance of venting in port during ballasting operations.
   

5. 
   Safety
   

1. 
   Inert gas procedure;
   
2. 
   Maintenance and monitoring of inert gas quality and pressure;
   
3. 
   Stopping of washing/discharge under abnormal inert gas conditions;
   
4. 
   Electrostatic generation and the precautions required to avoid it;
   
5. 
   Pipework integrity;
   
6. 
   Avoidance of surge pressures;
   
7. 
   Spillage.
   

6. 
   Check lists
   

1. 
   Before entering port;
   
2. 
   Before commencing crude oil washing;
   
3. 
   After crude oil washing;
   
4. 
   After sailing.
   

7. 
   Regulatory enforcement procedures
   

1. 
   Operations and Equipment Manual;
   
2. 
   Oil Record Book;
   
3. 
   Sounding of tanks;
   
4. 
   Measurement of oil on top of departure ballast.
   

8. 
   Maintenance of plant and equipment
   

1. 
   Maintenance of equipment in accordance with manufacturers' instructions;
   
2. 
   Additional maintenance items.
   

Administrations shall ensure that the training facility issues an appropriate document to those qualified in accordance with this Appendix to serve as officers primarily responsible for crude oil washing.
