Tanks

Types of tanks

• Fuel
• Fresh water
• Waste water:
  • Grey water
  • Black water
• Dirty oil
• Return oil
• Lube oil

General considerations

• Tanks are being considered as full when filled at 98% to allow room for expansion
• Low level alarm is at around 10%, high level at 95% and high high level at 98%
• Fuel and fresh water tanks require a breather line with the same diameter as the fill line to avoid spilling when filling with pressure.

Fuel tanks

• Fuel tanks require paint inside to avoid corrosion (only for full tanks corrosion is not an issue but this is only applicable for boats in 24h service)

Waste water tanks

• Waste water tanks require a breather line with the same diameter as the suction line to avoid collapsing during emptying. Instead of a large diameter breather line a valve can be applied.
• Deck suction connection conform ISO...
