Вставка

- Two tanker operations that have the greatest impact on the safety of personnel and of the environment are Cargo tank cleaning for man-entry, and the disposal of slops.
On completing this chapter you will have an understanding of:
• Why following a good plan of tank cleaning operations helps in the safety of personnel.
• Why the location of the Ship, the condition of Oil in the bottom and oxygen in the atmosphere of tanks should be
• Checked in preparing for tank cleaning apart from ensuring that the vessel is not in one of the designated MARPOL Special Areas.
• When the overboard discharge line blank should be removed.
• How to take in water safely for tank cleaning.
• What is open cycle water washing and the advantages of closed cycle water washing?
• Why purging with inert gas is necessary and when a tank is gas free enough for crew to enter.
• All tank cleaning including cow and discharge or decanting of wear from slop tanks Is to he recorded in the Oil Record book part I.

excellent videos i have 10 years expiries in tank cleaning
Excellent videos... congratulations
Glad you like them!
So the Water containing traces of oil goes into the sea?
I have been working about cleaning 🧹 tanks.
🎯 Key Takeaways for quick navigation:
00:24 🧼 Proper cargo tank cleaning and slops disposal are crucial for safety and environmental protection in tanker operations.
00:50 💧 Preparing for tank cleaning involves checking the ship's location, removing overboard discharge line blanks, understanding water washing methods, and the importance of purging with inert gas.
01:16 📝 All tank cleaning activities, including crude oil washing, should be recorded in the oil record book part 2.
02:21 📅 Detailed planning of tank cleaning operations, including rest hours for personnel, is essential to ensure safety.
03:24 🌊 Consider the sea water temperature when planning tank cleaning, and drain cargo tank bottoms if necessary after entering warmer seawater.
05:12 ⚡ Use inlet diffusers in slop tanks to prevent static electric sparks during tank cleaning.
06:32 🚰 Open-cycle tank cleaning involves pumping water from the sea and discharging it overboard after passing through slop tanks.
07:37 💧 Secondary slop tanks should be kept as free of oil as possible, and bottom stripping of cargo tanks is necessary before commencing tank cleaning.
10:11 🔥 Closed-cycle tank cleaning is used for certain cargoes and conserves heating fuel by recycling water from slop tanks.
11:51 🌬️ Purging with inert gas ensures a safe tank atmosphere by reducing hydrocarbon vapors to less than 2% before introducing air.
12:53 🌫️ Ventilate tanks with inert gas fans or compressed air to ensure safe entry and maintain communication between the bridge and the deck.
13:58 📋 Maintain a logbook, follow environmental and commercial guidelines for slop tank management, and decant slops before arriving at the loading port.
16:32 🔄 Slow and steady pumping during slop tank decanting keeps oil-water layers intact and prevents inadvertent discharge of oil.
18:38 📏 Measuring the density of slop oil is important for determining its value and quantity, especially if it contains multiple grades of crude oil.
21:22 💰 The ship owner can lose money if slops are retained onboard or discharged based on the cargo and charterer's decision; communication is key.
