Double Banking Operation

Sometimes ships are required to perform cargo operations with barges in an anchorage or more commonly to take bunkers. The North P&I Club and TANKEROperator have published some valuable guidelines. In this section, we present which hazards a risk analysis should include when a ship’s operator and master are planning such an operation.

Lack of crew training

1.  Training and familiarisation of the ship’s crew with all the details of the operation taken.

Breach of ship Security

1. Declaration of Security (DOS)
2. Specific Security Assessment has got the details below:

• Security communications
• Action in event of a breach in security
• Local regulations regarding exclusion zones
• Current security level enforced by the port
• Security on various vessels (e.g. Barges)
• Dangers associated with accommodation doors
• Actions on the presence of unauthorised craft alongside

Unfavourable weather conditions

1. Monitoring forecasting to the prevailing environmental conditions (visibility, wind and waves)
2. If applicable, attention is given to operations in cold weather and/or ice conditions
3. Training is delivered for rolling and pitching movements.
4. Plan actions if an electrical storm is expected

Fire during cargo operations

1. Smoking and use of naked lights is prohibited
2. Readiness of fire-fighting equipment
3. Precautions against the use of radio and satellite communication equipment addressed

Electrical hazards

1. Risks associated with earths on electrical switchboards identified by the ship’s electrician.
2. Electrical isolation between the two ships is discussed

Contingency Planning

1. Training for helicopter medical evacuation operations
2. Self-contained breathing apparatus and lifeboats and life-rafts ready for emergency evacuation
3. SOPEP equipment made available in case of an oil spill
4. Familiarise with procedures for reporting oil spill as per SOPEP

Change of Command Failure

1. Master stands at all times liable for the safety of the ship, its crew, cargo and equipment
2. Only master approves any machinery operations about main engines, emergency power, steering gear, boilers, fuel changeover 

Cargo Spillage

1. IMDG Code sections are studied in event of cargo leakage on either vessel
2. Material safety data sheets (MSDS) for the products being available onboard

Ship Drag, Collision

1. Radar usage discussed with navigation officers
2. Monitor broadcast of navigational warnings 
3. Complete a specific passage plan if the operation is to be conducted en route
4. Preparation of ship before manoeuvring
5. References of various navigational signals to be used

Health Hazards

1. Personal protective equipment is provided for the cargoes handled

Communication Failures

1. Shipboard general communications established
2. A common language for communication is established (internal and foreman) 
3. Ensure that any information requested from the ship are presented by the agent
4. Addresses communications during arrival, departure, mooring and unmooring
5. Establish procedures in place for communication failure

Mooring/unmooring operations failure

1. Risk Assessment for mooring operations at sea addressed
2. The ability of the ship’s mooring system has been examined for the following:

• Danger of excessive tension in mooring lines between the vessels
• Mooring line lead angles
• Awareness of weather thresholds
• Cautions against long-period waves
• Directions of wave encounter 
• Elasticity of mooring arrangement
• Chafing protection

Coating damage of the ship’s hull

1. Fenders to be used and rigged
2. Condition of fenders is verified by crew
