Design orders for new submarine cable construction vessels acquired in 2007

It is reported that the ship is a major project construction project of Guodian Group, which is mainly used for offshore wind farm sea cable installation facilities, inter-island interconnection power supply and sea cable maintenance. The construction background is the 500KV UHV Zhoushan network project. Since the project needs to use the ship in May 2018, the project schedule is very tight. According to the contract requirements, the project needs to complete the preparation of the project design and construction bidding documents in February, and complete the details in June. Design work, scheduled for delivery in March 2018. At present, the design work of the project has been fully carried out. In order to ensure the various planning nodes of the project, the project team members are working overtime to carry out follow-up design work.

As the most advanced submarine cable construction work ship independently developed and designed in China, the ship is equipped with DP1 level power positioning and anchoring positioning system, and international advanced sea cable construction equipment, mainly used for laying submarine power cables and composite cables. Compared with the cabling ship designed by the previous seven-eighth communication cable and the small power composite cable, the whole ship system configuration is more complicated and technically more difficult. The overall design appearance and layout of the ship should conform to the aesthetics, atmosphere and comfort; the function setting should meet the practicability (control investment and meet the actual use), scientific (the operation process meets the requirements of the actual construction operation, the key system and equipment configuration should reflect the science Reasonable), economic (investment scale and operating income), advanced (excellent ship performance, advanced and reasonable selection of key equipment) and other principles.

After receiving the pre-ship information of the ship in early 2016, the company began to closely follow the project. During the period, it conducted several business promotion and invited the owners to visit, relying on the solid technical strength and good industry reputation. The initial approval of the owner has occupied the market initiative. At the initial stage of the project, 708 people organized various personnel to go to Zhoushan to carry out technical exchanges and research, assist the owners to complete the project feasibility report, provided technical support for the project's advancement, and laid the final bid for the project. basis. In the current increasingly competitive offshore and engineering ship market, the seven hundred and eight are determined to go upstream and win new orders and create new situations.

Zhoushan Qiming Electric Power Group Co., Ltd., formerly known as Zhoushan Electric Labor Service Company, is a collective enterprise affiliated to Zhoushan Power Supply Company. Located in the service support unit of Zhoushan Power Grid construction, Qiming Power Group Corporation seized the opportunity of the development of the island power grid, fostered strengths and circumvented weaknesses, and after years of baptism of submarine cable engineering, gradually mastered and explored a core technology of submarine cable construction, becoming the only one in the country. At the same time, it has a submarine cable construction enterprise with general contracting for electric power construction, professional contracting for port and coastal engineering, and qualification for electric power installation. It is also the only enterprise specialized in submarine power cable laying, overhaul and maintenance in Zhejiang Province.

Qiming Power Group attaches great importance to the improvement of equipment technology level and has deployed a number of professional engineering vessels. The "Shudian No.7", "Zhoudian No.8", "Zhoudian No.9" and "Building Cable No.1" are all equipped with operational vessels. There are advanced navigation and positioning control systems, submarine cable routing control systems, "global eye" monitoring systems, buried plow control systems, etc., and the introduction of high-tech equipment such as underwater robots, ship technology has reached the international leading level.

In particular, the main construction ship "Building Cable No. 1" is equipped with equipment such as ship-mounted electric pallets, hydraulic jet-buried ploughs, underwater positioning systems, and buried depth monitoring systems. Among them, the 10-month, total investment of 6 million yuan, the ship-borne large-scale submarine cable tray system independently developed by the submarine cable engineering company, filled the gap in the domestic sea cable construction field.
