Special attention ｜ It is a moment of trouble to cause trouble

The Swedish Capital Association (Swedish Club) shared an accident on its latest monthly safety scenario analysis.

✍The incident pass

A 15 -year -old bulk carrier was completed for the third special inspection in the dried dock. At the same time, the ship also carried out many other maintenance operations, including replacing a section of breathable pipe in the cargo cabin.

Dagai found in a cargo cabin inspection a month ago that the breathable pipe seemed to be corroded. This pipe extended from the bottom of the sea, passed through the cargo cabin and heavy fuel (HFO) cabin, and finally passed through the shell board. After discovering this problem, it was greatly decided to replace the tube section in the cargo cabin and install a protective device to prevent damage during the loading and unloading process.

However, the vice deputy believes that there is no need to check the pipeline part in the heavy fuel cabin, and there is no arrangement of the heavy fuel tank during the dry dock. The damaged pipe section was replaced by the shipyard. After the ship was repaired, the ship left the shipyard and drove to the loading port under the pressure state.

One morning, the ship arrived at the unloading port for refueling operations. A refueling boat came next to it, and the large tube ship completed the refueling checklist. About an hour later, the fuel operation began. At this time, the goods operation has also begun.

At lunch, a first -class sailor found oil in the water and notified the duty staff of the goods office (OOW). When the first -class sailor came to the deck, he could see that the oil flowed from the hull side. When he walked into the goods office, he roughly explained the pollution situation and which side of the oily ship overflowed from the ship. Soon after, he called the captain and told him that there was oil leak on the ship. The captain informed the incident to the Coast Guard, Port Authorities, and designated personnel (DPA) on the shore.

At this time, the header of the duty also called OOW to ask what happened. OOW told him the oil leakage and asked if the fuel operation had stopped. The header on duty replied: "No." OOW told him to stop refueling immediately, and then ran back to the deck to meet with the captain and the head of the ride. Although the fuel operation has stopped, the fuel is still overflowing, and the head of the turbine realizes that the fuel is overflowing from the heavy fuel cabin (being added). Essence Almost all fuels were transferred away, and finally no longer dripped.

Soon after, the port authorities arrived at the scene and placed a fence and absorbing pad around the ship. Unfortunately, the fence has failed to completely stop the fuel leakage. When all the fuel has been transferred and the oil compartment can enter safely, the crew checked the heavy fuel tank and found that the airb time had ruptured. They perform temporary maintenance of the pipeline, but permanent maintenance must be completed in the shipyard.

✍ Experience lessons

The Swedish Casino Association pointed out that the corrosive pipeline in the cargo cabin pressured a pipeline in the heavy fuel tank. After the operation of any pipeline is completed, the pressure test should be performed immediately; the thickness of the entire pipeline should be measured; if the pipeline cannot be avoided through the heavy fuel cabin, the thickness of this part of the pipeline should be increased, and some surface protection measures should be taken, such as hot immersion galvanized galvanized galvanized galvanized measures, such as hot -dip galvanized galvanized galvanized galvanized galvanized measures, such as hot -dip galvanized galvanized galvanized galvanized measures, such as hot -dip galvanized galvanized galvanized galvanized measures Or add coating.

The Swedish Cosmetics Association also suggested that everyone think about the following issues:

● Is there a pipeline in the cargo cabin on the ship?

● Is there a pipeline on board through the fuel cabin?

● How long does it take to check the heavy fuel cabin?

● Check the pipeline when checking the fuel cabin?

● Is the ship's dry docking program sufficient?

● Does the ship maintenance plan (PMS) include the pipeline?

● Is there a risk assessment of such risks on board?
