Dalian COSCO SHIPPING Heavy Industry completed the BWMS project of the “Xin Hai Tong 22”

A few days ago, the “Xin Hai Tong 22” vessel under construction by Dalian COSCO SHIPPING Heavy Industry Co., Ltd. completed the ballast water treatment system retrofit and regular repair works and set sail ahead of schedule.

“Xin Hai Tong 22” is a bulk carrier under Fujian Haitong Development Co., Ltd., with a length of 190 meters, a beam of 32 meters, a deadweight of 60,000 tons, and an age of 11 years. The main line of maintenance work in the factory is ballast water transformation. Since the ship was purchased by the ship-owner company just now and the crew was newly taken over, the ship-owner did not fully understand the current state of the ship, which affected the inspection of the project to a certain extent.

After the ship entered the factory, the ship repair management team immediately arranged for the staff to carry out the ballast water reconstruction according to the layout of the existing drawings. This type of ship is designed as a monorail catering crane, and all materials must be transported back into the engine room by using this crane. However, when it was necessary to use a crane for reverse transportation, it was found that the traveling motor of the crane was damaged and could not be used. The management team immediately communicated with the shipowner to find spare parts from Shanghai. During the process of installing the new motor, the management team found that the size of the new motor and the old gearbox did not match. The management team immediately organized professional technicians to transform the motor before it could be installed smoothly, and this small episode also brought about a tight construction period variable.

In order to maintain the construction period, from the production workshops to the single-vessel project team, everyone tried their best to overcome the shortage of construction manpower after the Spring Festival and the impact of a new round of epidemic in the Dalian area. The project has advanced the original sailing schedule on March 19 by three days.

Just one day before the ship sailed, when the project entered the final stage, an emergency occurred in the project. The windlass hydraulic valve purchased by the shipowner could not be installed properly due to the wrong flange size. In order to ensure the shipping schedule, the general management team rose to the challenge, quickly adjusted manpower to replace the damaged pipeline, discussed the valve modification plan, and carried out emergency repairs. Finally, all the engineering and debugging of the hydraulic system were completed on the morning of March 16, ensuring that the ship was on time. Set sail from the factory.

After the ship left the port, the maintenance representative of the shipowner Fujian Haitong Development Co., Ltd. sent a letter of thanks to the general management team of Dalian COSCO SHIPPING Heavy Industry Co., Ltd. for being able to complete all the scheduled projects with high quality and as planned, and to deal with the on-site various projects calmly. Such emergencies were highly recognized and appreciated.

大连中远海运重工高效完成“新海通22”压载水工程获赞誉

日前，大连中远海运重工承修的“新海通22”轮完成了压载水改造及常规修理工程，提前开航。

“新海通22”轮系福建海通发展股份有限公司旗下散货船，船长190米，型宽32米，载重6万吨，船龄11年，此次进厂维修主线工程为压载水改造。由于该轮为刚刚船东公司购置且船员也是新接手，船东对船舶的现有状态并不十分了解，这一定程度上影响了工程的勘验。

船舶进厂后，修船总管小组立刻安排工作人员按照现有图纸的布局进行压载水改造施工。此船型设计为单轨式伙食吊车，所有物料必须使用此吊车才能倒运进机舱。然而就在需要使用吊车倒运时，发现吊车的行车马达已损坏，无法使用。总管小组立即与船东沟通，从上海找到备件。在安装新马达过程中，总管小组又发现新马达与旧齿轮箱尺寸不符，总管小组立即组织专业技术人员对马达进行改造才得以顺利安装，而这一小插曲也给本就紧张的工期带来了变数。

为保工期，从各生产车间到单船项目小组，大家尽力克服春节后施工人力紧张及大连地区新一轮疫情的影响，坚定信念、分秒必争、周密计划并如期完成了该轮的压载水改装工程，将原定3月19日开航计划提前了三天。

而就在船舶开航前一天，工程进入收尾阶段时，工程出现了突发情况。船东购买的锚机液压阀门由于法兰尺寸错误不能正常安装。为保障船期，总管小组迎难而上，迅速调整人力更换破损管路、讨论阀门修改方案、进行紧急修理，最终在3月16日上午完成了液压系统的所有工程及调试，保证了船舶按时离厂开航。

在船舶离港后，船东福建海通发展股份有限公司的机务代表发来感谢信，对大连中远海运重工的总管小组，既能够高质量的按计划完成所有既定工程，又能够从容不迫地处理现场各种的突发问题，给予了高度认可和赞赏。
