Brief Talk About Steel Coil Loading And Unloading

Steel trade is an important part of world trade, and finished steel products are mainly exported to China, South Korea, Japan, Vietnam and Taiwan and other countries and regions. With major loading ports such as Shanghai, Zhangjiagang, Lianyungang, Tianjin, Kaohsiung in Taiwan, Pyeongtaek, Inchon, Pohang, Kwangyang in South Korea, Oita in Japan and Vungtau in Vietnam, trade is concentrated in Europe, America and Southeast Asian countries.
Regarding ship steel loading, I mainly combine a little steel loading experience from the spare cabin, cabin inspection, strength accounting and loading, skidwood arrangement, lashing, ticket partition, first mate receipt signing, cargo management on the way, unloading at the port of unloading, etc., to talk about a little humble opinion on steel loading. Mistakes are inevitable, please criticize and correct, and do not hesitate to give advice.
As we all know, steel cabin inspection requires strict cargo compartment requirements, requiring the cargo compartment to be clean and free of residual cargo, dry, salt-free, sewage well drying, etc. If the voyage of the two ports is short, and the cargo on the voyage is difficult to clean the cargo such as coal, nickel ore, etc., and catch up with adverse factors such as bad weather and sea conditions after sailing, it is necessary to draw up a detailed and specific spare space plan on board, due to the tight time and insufficient manpower, so it is necessary to start the spare space work at the unloading dock, each cargo hold is completed, and the time in port should be used to remove the residual cargo as much as possible, including sewage wells, to ensure smooth drainage when cleaning the cargo hold, and to avoid poor drainage caused by the loss of time for the spare compartment.
If it is possible to obtain the consent of the port side through the agent as much as possible, rinse and clean bulkhead cargo stains with plastic brushes while in the port, but note that the MARPOL Convention and most ports do not allow the discharge of cargo sewage in the cargo compartment.
In recent years, P&I clubs have suffered cargo damage and caused cargo owner claims, mainly caused by cargo damage, deformation, friction, moisture and cargo rust caused by water ingress in the cargo hold.
In view of this, when preparing the cabin, focus on high-pressure fresh water cleaning of the hatch circumference, imagine if it contains salt in the future, if the cargo compartment sweats, dripping to the cargo under the hatch circumference, it is easy to cause cargo damage under the hatch circumference, and must ensure that the Drain channel around the cargo hatch circumference is unblocked, otherwise it is easy to make sweat dripping onto the cargo and causing cargo damage.
Therefore, it must be required that hatch circumference, ramp board, floor, sewage well, etc. are very easy to be inspected by Surveyor, such as the cargo compartment of the Australian elevator straight ladder, bilge plate, ramp board, etc. as high as possible to fully high-pressure fresh water cleaning, it should be noted that after the seawater flushes the cargo hold, in order to prevent salt crystallization, it is best to rinse with fresh water when the seawater is not dry, so that the residual salt will be significantly reduced, and save fresh water to a certain extent, now many port cabin inspections have passed the Silver nitrate test, A little salt can reflect the appearance of white, and Surveyor will think that it is not clean, so it is important to pay attention here. After docking, all kinds of procedures are completed, there are two cabin inspection Surveyor, and it is best to divide the ship into two teams, one team is led by the captain and others, and the other team is accompanied by two teams such as the first mate and others. Generally, Surveyor will first take pictures of the bulkheads and bilge plates around the cabin, and then use Silver nitrate to randomly sample and test the cabin everywhere, and take pictures, and then the watertightness of the hatch, South Korean ports will carry out CHALK TEST on the hatch rubber strip, and some ports of HOSE TEST but this method has also been gradually eliminated, HOSE TEST is easy to cause salt to the hatch and hatch, more and more are replaced by ultrasonic tests, So be sure to pay attention to the hatch watertightness test, the cabin inspection time is about an hour, during which Surveyor may chat with the ordinary crew on the ship, such as interns, specifically ask them how to prepare the cabin on the ship, in this case, must not answer, let the ship’s first mate or captain explain it, to prevent them from being short-inexperienced, wrong answers, and causing passivity on the ship.
