natural rubber, synthetic rubber, reclaimed rubber, carbon black, various additives, fillers, matrix materials etc.The term rubber is derived from the Indian cau-uchu, meaning "tree of tears," a highly resilient polymeric material with reversibly deformable properties that is flexible at room temperature and produces large deformations with little external force, Remove the external force can restore the status quo. Rubber is a completely amorphous polymer with a low glass transition temperature (T g) and a high molecular weight, often greater than a few hundred thousand.
The early rubber was latex from plant such as rubber tree, rubber grass and the like, which was made of processed materials with elasticity, insulation, imperviousness and air. High elasticity of the polymer compounds. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is made from rubber tree, rubber grass and other plants made of plastic processed; synthetic rubber by a variety of monomers derived by polymerization. Rubber products are widely used in all aspects of industry or life.
Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability. Isoprene rubber raw (raw) strength was significantly lower than natural rubber, but the quality of uniformity, processing performance superior to natural rubber. Isoprene rubber can be used in place of natural rubber to make truck tires and off-road tires. It can also be used to produce various kinds of rubber products.

On September 8, 2010, the COSL225 Indonesian workover support contractor built by China Merchants Heavy Industry (Shenzhen) Co., Ltd. completed the delivery of the barge ahead of schedule. On September 16, 2010, China Merchants Heavy Industry held the COSL225 delivery ceremony at the Weizhou Island Shipbuilding Base.
Mr. Wang Cuijun, Deputy General Manager of China Merchants Industrial Group and General Manager of China Merchants Heavy Industry (Shenzhen) Co., Ltd., Mr. Cao Shujie, Vice President of China Oilfield Services Co., Ltd., Mr. Luo Youan, General Manager of CNOOC Garment Management Department, and Mr. Zhonghai Oil Service Ship Division Mr. Chen Linting, Mr. Chen Shaoting, General Manager of COSL Shenzhen Branch, Mr. Li Guowei, General Manager of ABS Classification Society (China), Mr. Tan Haoxiu, General Manager of CCS Classification Guangzhou Branch, and Director Xu Zongquan of Shenzhen Maritime Bureau attended the meeting and guests. Delivery ceremony. The delivery ceremony was presided over by Mr. Tu Fengqing, Executive Deputy General Manager of China Merchants Heavy Industry (Shenzhen) Co., Ltd. Leaders such as Mr. Wang Cuijun and Mr. Cao Shujie delivered speeches at the ceremony.
The barge is a non-self-propelled, offshore oil workover support barge with two 80t-13m/14t-45m and 10t/27m cranes, a 140-person living room and a diesel and drinking water storage area, and China Merchants Heavy Industries undertakes the ship. Overall construction of production design, equipment acquisition, hull construction, equipment installation and commissioning. The vessel will enter the ABS and BKI classification society and will be used for the support of offshore engineering oil and gas field development and workover projects. The water depth will be 30 ~ 60 meters. After delivery, it will be rushed to the CNOOC SES oilfield block in Indonesia for workover support operation. .
The ship is the fourth offshore oil workover support barge built by China Merchants Heavy Industry Co., Ltd. for CNOOC. It is another trust cooperation between China National Offshore Oil Corporation and China Merchants Heavy Industry on the basis of the successful construction of COSL 221/222/223. The project contract was signed at the end of November 2009 and was delivered to the ship in October 2010 according to the shipowner's plan.
COSL225 is the most intense construction period of China Merchants Heavy Industry. Focusing on the characteristics of the project, it focuses on the goal of “delivering in advance, improving quality, creating a brand for Chinaâ€. Heavy industry actively integrates resources and vigorously cooperates with ship owners and classification societies. Cooperate, overcome the delays in equipment delivery, construction work in the rainy season and so on, and gradually realize the major construction nodes ahead of time and step by step. On the basis of the already very tight construction period, the overall schedule is earlier than the shipowner’s request. Delivery in 30 days.
As the only offshore ship that is currently delivered in all offshore engineering and ship projects under construction in COSL, COSL225 has successfully completed the cooperation relationship between China Merchants Heavy Industry Co., Ltd. and COSL, and also reflects the investment in heavy equipment in the field of marine engineering equipment. Construction strength and advanced level.
