COSCO(Weihai) BOS BWMS

Recently, the deeply optimized and upgraded Blue Ocean Shield (BOS) Ballast Water Management System successfully passed the USCG shore-based supplementary test, marking the recognition of the effectiveness of the product’s optimization and upgrading and an important breakthrough. COSCO(Weihai) Shipbuilding Marine Technology Co., Ltd (WECOSCO) has further improved the level of quality services provided to customers throughout the process.

The BOS BWMS is mainly upgraded in the following three aspects: First, the discharge process is optimized. The new process discharge no longer needs to go through the filter, which simplifies the operation process, improves the filter life, and improves the actual ship of the system. Applicability; Second, for all salinity waters, the storage time of ballast water treatment is shortened from 24 hours to 2 hours, which can meet the application requirements of all ships in the world, especially for container ships sailing in short distances, and loading and unloading are no longer necessary. Being limited, it can protect the interests of shipowners to the greatest extent; third, the overall operating power of the equipment is reduced by about 12%, which effectively improves the power consumption and economy of the system.

It is worth noting that the above optimization and upgrading can meet the latest technical optimization only by improving the control program operation process, without the need to upgrade hardware equipment and components, which is very convenient and does not cause the shipowner to incur upgrade costs.

In 2020, the company will plan related optimization and upgrading work through calculation and evaluation. In order to fully verify the technical feasibility of the system upgrade, in September 2020, the company’s internal test base was implemented and passed the self-test of the optimization scheme. After that, WECOSCO started the formal test. At the end of 2020, WECOSCO formally submitted an application for optimization testing to DVN. In March 2021, it obtained the approval of the USCG and DNV for the optimization and upgrading test plan and began the formal shore-based testing in September. Under the professional arrangement of the USCG laboratory of Shanghai Ocean University, BOS BWMS products completed all 15 rounds of shore-based tests in just two and a half months, and all the tests were successfully passed at one time, reflecting the excellent performance and high reliability.

威海科技海盾压载水系统优化升级取得进一步突破

近期,深度优化升级的海盾压载水管理系统顺利通过USCG岸基补充试验,标志着产品的优化升级的有效性获得认可,取得重要突破,威海科技为客户提供全过程优质服务的水平进一步提高。

海盾压载水管理系统主要在如下三方面进行升级:一是优化排载流程,新流程排载不再需要经过过滤器,简化了操作流程,提高了过滤器寿命,提升了系统的实船适用性;二是针对所有盐度水域,压载水处理存放时间由24小时缩短至2小时,能够满足全球所有船舶的应用要求,尤其是对近距离航行的集装箱船,装货、卸货不再受到限制,能够最大限度的保护船东利益;三是设备整体运行功率降低了12%左右,有效提升了系统功耗和经济性。

值得关注的是,以上优化升级仅通过完善控制程序操作流程,即可满足最新的技术优化,无需进行硬件设备和部件升级,非常便利,同时不使船东产生升级成本。

2020年,公司即通过计算、评估筹划相关优化升级工作。为了充分验证系统升级的技术可行性,2020年9月在公司内部试验基地实施并通过了优化方案的自测试验。之后,威海科技开始了紧锣密鼓的正式测试。2020年底威海科技向DVN正式提交了优化测试申请,2021年3月取得USCG和DNV对优化升级测试方案的认可,9月份开始正式岸基测试。在上海海洋大学USCG试验室的专业安排下,海盾产品仅两个半月就完成了全部15轮岸基测试,所有测试均是一次性成功通过,体现了海盾压载水产品优秀的性能和高度可靠性。
