📍#DidYouKnowThat📍 ✅ To avoid brittle fracture occuring ❌, measures 🚧 are taken to ensure that #LNG 💧 doesn't come in contact 🚫 with steel structure of the ship 🚢. ✅ The manifold area is equipped with #stainless #steel drip trays that drain the cargo away 🎯 from the ship's deck and sides, combined with #Water #curtain 💧in the event of spillage. ✅ Fire hoses must be available at each cargo dome 📌 to deal with any small leakages that may develop 📈 at valves and flanges and permanent drip trays are fitted underneath the items most likely to leak. ✅ The below photo👇shows the port manifold of an #LNG ship during Loading/Discharging operation. 📷: LNG shipping knowledge #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping 

📍#DidYouKnowThat📍 🚨What is the material used for the LNG #Moss type cargo containment❓ ✅ The cargo containment system consists of insulated independent #spherical tanks constructed from 👉#aluminium alloy and designed to carry #LNG at cryogenic temperatures and at a pressure close to 👉atmospheric pressure. ✅ The tanks are encased within 👉#void spaces and situated in-line from forward to aft within the hull. The spaces between the inner hull and outer hull are used for 👉#ballast and also provide protection to the cargo tanks in the event of an emergency situation🚨, such as a collision or grounding. ✅ There is no ❌FULL secondary barrier as the tanks, primarily due to their #spherical construction, have a high degree 🎯 of safety against fracture or failure🔴. The tanks are heavily insulated with approximately 2️⃣0️⃣0️⃣mm of 👉#polystyrene foam to reduce boil-off to a minimum📉. 📷 : LNT Marine #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping

📍#DidYouKnowThat📍 ✅ LNG cargo tank contamination ❌ after post refit / repair 🏭 can only occur by one of two 2️⃣ means, namely : 👉 Contamination taken onboard during the loading process 🚨, ie across the manifold from the terminal. This is prevented by in-line loading filters 🎯 fitted in the ship's manifold, typically a size 6️⃣0️⃣ mesh. Pressure differential across the manifold filters is a parameter 📊 that should be monitored onboard during the loading process. Remember that it might not be debris that causes a partial blockage, but ice formation ❄. 👉 Contamination from ship 🚨, usually as result of equipment/material failure, ie Teflon valve seat, corrosion, etc. Again 6️⃣0️⃣ mesh discharge filters 🎯 are fitted in the ship's manifold so that any debris is contained and not passed on to the receiving terminal. ✅ After each #load or #discharge operation, the appropriate filters should always be inspected and if any debris found, investigation 🔴 should be taken to determine its origin. 📷: KOMARINE #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping 

📍#DidYouKnowThat📍 ✅ If both cargo pumps fail 🚨 for an #LNG ship #Moss type cargo tank, the remaining cargo can be transferred to another cargo tank by #Pressurising 📈 the tank with failed pumps 🔴, and using that excess pressure to force the liquid 🎯 into one or more of the other cargo tanks. ✅ The pilots for the cargo relief valves 📌 will have to be changed out from their normal setting of 2️⃣5️⃣0️⃣ mbar as follow : 👉 9️⃣8️⃣0️⃣mbar - Start of pressurising 📈 from full tank to one-half tank 📉. 👉 1️⃣9️⃣9️⃣6️⃣ mbar - Start of pressurising 📈 from one-half tank to empty tank 📉. 📷: Piping arrangement inside Moss cargo tank - LNG Shipping knowledge. #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping

📍#DidYouKnowThat📍 ✅ The #LNG ship cargo containment 🚧 has a 👉 thermal insulation 🛑 fitted around the cargo tank in order to 👇 🎯 Minimise heat flow 🔴 into cargo tanks and so reduce 📉 cargo boil off. 🎯 Protect the ship structure around cargo tanks 🚧 from the effects of the cryogenic temperatures of LNG. ✅ The following are the main materials used for insulation in gas carrier construction : 👉 Polyurethane 👉 Mineral Wool 👉 Balsa 👉 Perlite 👉 Polystyrene 📷 : Cargo containment GTT No 96 tank  👉 Source : GTT Newsletter #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping 

𝐏𝐢𝐩𝐞𝐃𝐞𝐟𝐞𝐧𝐝𝐞𝐫® may be used in bores as a means to protect the pipe from abrasion, gouging and/or to isolate the pipe from a casing. The installation differs from a traditional approach due to the added friction. "𝐁𝐮𝐢𝐥𝐝 𝐚 𝐬𝐚𝐟𝐞𝐫 𝐩𝐢𝐩𝐞𝐥𝐢𝐧𝐞."

📍#DidYouKnowThat📍 ✅ Should an #LNG leak or spill occur 🚨, a fire hose should be trained at the liquid pool to disperse and evaporate 🎯 the liquid and protect 🚧 the ship's steelwork. The source of the leak must be stopped, ceasing cargo operations if necessary 🚫. ✅ Should a major leak occur 🚨, cargo must be stopped immediately ❌, the ship's general alarm sounded and the deck water spray system activated. ✅ The below photo 👇 shows a major #LNG spill occurred 🔴 during #LNG discharging due to tank overflow💧. 📷 : Tradewindsnews #lng #lngindustry #lngshipping #lngbunkering #gtt #mossdesign #naturalgas #shipping
