Which type of fire suppression system is most commonly used in tanker cargo pump rooms?
Answer: CO2 or fixed foam system
Cargo pump rooms typically use CO2 or fixed foam systems because they effectively suppress hydrocarbon fires without damaging electrical equipment.
What is the purpose of a vapor recovery system (VRS) on a tanker?
Answer: To capture and control cargo vapors during loading to prevent atmospheric release
Vapor recovery systems capture hydrocarbon vapors displaced during cargo loading, preventing pollution and reducing fire/explosion risk at terminals.
On a tanker, the term 'overfill protection' refers to:
Answer: Independent alarms and shutoffs that prevent cargo tanks from being loaded beyond safe limits
Overfill protection systems include independent level sensors and automatic shutoffs that stop loading before a tank can overflow, preventing spills and structural damage.
What is the danger of electrostatic discharge in tanker cargo operations?
Answer: It can ignite flammable vapors during loading or cleaning operations
Static electricity generated during cargo flow or tank cleaning can discharge as a spark in a flammable atmosphere, potentially causing an explosion.
A 'closed loading' procedure on a tanker means:
Answer: Cargo is loaded through closed systems with vapors vented to a recovery system or inerted
Closed loading keeps the cargo system sealed, routing displaced vapors to a VRS or through inert gas systems, reducing fire risk and atmospheric pollution.
What is the purpose of bonding cables used during tanker cargo transfer?
Answer: To equalize electrical potential between the ship and terminal, preventing static sparks
Bonding cables connect the ship to the shore facility to equalize electrical potential, eliminating the risk of a static discharge spark at the connection point.
Which document outlines the agreed safety procedures between a tanker and a shore terminal before cargo operations begin?
Answer: Ship/Shore Safety Checklist
The Ship/Shore Safety Checklist (SSSCL) is a jointly completed document ensuring both parties agree on safety conditions and procedures before starting cargo transfer.
