76,000 tons of product oil tanker On October 26, the 76,000-ton product oil tanker No. 5 built by the ship's platform was returned to the company by sailing test and began to finish the project. The ship achieved 63 days of sailing in the water, and the navigation test took only 3 days, reaching the best level of the same series of ships.
The 76,000-ton product oil tanker No. 5 is a vessel that is required to be delivered in advance after the Dalian Shipbuilding Heavy Industry Plan is adjusted. The berth was carried out during the construction phase of the berth, and the research and application of the rapid loading process was carried out, which accelerated the progress of the sub-group and the closing, saving time. In addition, by establishing a reasonable crane usage plan and strengthening the interference check of the general group and the closing, the main crane operation time and invalid waiting time are shortened. The ship was launched in advance on August 20, and it also created a new record for the 80-day berth cycle of the same series of vessels, and for the first time in the pontoon phase, the load test of the main oil stringer and generator was realized.
According to the company's production plan, the 300,000-ton crude oil ship will have an underwater construction period of 3 months for the 300,000-ton series. For this purpose, the second part of the shipyard is based on the 88-day underwater cycle of the No. 10 ship. The goal of the No. 11 ship underwater cycle of 80 days.
In order to achieve this goal, the second part of the shipyard is centered on process capability, focusing on painting. According to the special organization of long-term work, the production planning is carried out according to the regional complete method, and a series of technological innovations have been carried out in the production organization of the No. 11 ship. . For example, for the construction of the series of ships, the actual implementation of the alignment in the dock is not carried out, and the bolt hole and bolt processing work originally carried out under the water is moved into the dock, saving 10 days, thereby ensuring that the host line is constructed underwater. Completed within the month.
On October 27th, the second part of the dockyard for the Maersk Group's 300,000-ton crude oil ship No. 11 was signed for delivery. The ship was built to achieve the best water integrity of the series of boats, with a minimum record of 62 days in the underwater construction cycle. As a result, the second part of the shipyard in the construction of the 300,000-ton series of ships not only achieved a large speed increase, but also the construction cycle has approached the level of Japan and South Korea.
On November 11th, the 2nd shipyard of the 29th ton of crude oil ship built by Zhonghai Group for the China Shipbuilding Group completed the successful return of all the test projects in 4 days. As a result, the second part of the shipyard continuously updated the navigation record of 300,000 tons of ships in less than one month.
On the basis of the six-day sailing period of the ship No. 11 of the 300,000-ton crude oil ship, the second part of the shipyard will carry out three major items of power loss, dead ship and high-power inquiry in the original trial test of the 298,000-ton ship No. 3, and move forward to The test was carried out before the test and successfully submitted, which created conditions for shortening the ship's navigation cycle.
110,000 tons of refined oil tankers On November 13, the 110,000-ton oil tanker No. 28 was successfully launched. The ship was bottomed for 39 days to form the raft, 55 days of main hull molding, 75 days to achieve the launch, creating the shortest period of 110,000 tons of series ship berth.
At the same time, the ship's launch integrity is also the best. In terms of hull, the inspection of all cabin structures before the launch of the ship is completed; in terms of armoring, the ship is the second ship to be installed in the shipyard after the ship No. 27; The integrity of the cable of the two generators is at the end of the total group stage; in terms of painting, the pumping chamber and the bottom of the clamping are all finished, which is a very big breakthrough compared to the previous vessel.
On November 14, the No. 30 ship of the 110,000-ton product oil tanker built by the second part of the shipyard for the company was held at the second workshop.
