IWS commissioning, service, and operation vessels (CSOV)

China Merchants Industry has received another order for two wind farm commissioning, service, and operation vessels (CSOV) from Integrated Wind Solutions AS (IWS) in Norway, with a total value of 96 million euros (about 672 million yuan).

On March 21, IWS announced that through its subsidiary IWS Fleet AS, it has signed a contract with China Merchants Industry for two wind power operation and maintenance vessels with “walk-to-work” capability. The new vessels will be delivered in the second half of 2024. , each costing $48 million.

IWS initially ordered 2+4 Skywalker-class wind power operation and maintenance vessels in the China Merchants Industry in March 2021, of which the first two are scheduled to be delivered in the first and second quarters of 2023. After the latest two alternative orders come into effect, IWS has two more alternative ships to take effect, and the delivery time is in the second half of 2024.

It is understood that this type of ship is 90 meters long, 19.6 meters wide, and has a design speed of 13 knots. It can provide 120 people with transshipment and support for life and operations at sea for more than 30 days. This is a high specification vessel specially built for the “walk-to-work” requirements of offshore wind farms, with an innovative design and flexible mission equipment to handle offshore wind farms during the installation, commissioning and operation/maintenance phases various tasks required.

The new ship adopts diesel-electric electric propulsion and DC busbar power distribution system, which has excellent berthing and maneuvering performance, and can realize efficient storage and transportation of wind farm equipment and spare parts; the ship is also equipped with a helideck, working boat (sub-vessel) and stern There is a CTV connection platform, and the efficiency of personnel transportation and deployment is extremely high; at the same time, the ship is equipped with DP2 dynamic positioning system, 3D wave compensation transmission gangway and 3D wave compensation main crane, which can realize personnel transfer and wind farm maintenance operations under severe sea conditions. The performance and work efficiency are much higher than similar ships.

The series of ships will be the first in the industry to be capable of zero-emission operations, designed by Kongsberg Maritime. Featuring a plug-in hybrid battery solution, using supercharging, solar cells, and batteries for fully electric operation, it can run for up to 6 hours with zero emissions. In the future, these ships can be converted to zero-emission ships at competitive costs, operate on batteries charged directly from offshore wind farms, biofuel compatible internal combustion engines, and be able to utilize amine fuels (fuel cells, ammonia, and methanol).

Thanks to the advanced technology, the fuel consumption of this type of vessel are 20% lower than that of similar risk operation and maintenance vessels currently under construction, and each vessel can reduce emissions by more than 1,300 tons of carbon dioxide equivalent per year. At the same time, the new ships will also be the first in the industry to bear the “DNV SILENT” symbol, which focuses on minimizing the impact on underwater marine life.

Among them, the construction of the first ship “IWS Skywalker” started in January this year, and after delivery, the operating contract with the Dogger Bank wind farm will begin in the summer of 2023. The world’s largest offshore wind farm, located in the UK North Sea, is scheduled to be commissioned between 2023 and 2025.

It is understood that IWS is a subsidiary of Norwegian shipowner Awilco. Founded in 1939, Awilco focuses on the investment and operation of shipping and offshore assets and has extensive experience in the offshore and shipping industries.

4艘超13亿!招商工业再获挪威船东高端风电运维船订单

招商工业再获挪威Integrated Wind Solutions AS(IWS)两艘风电场调试、服务和运营船(CSOV)订单,总价值9600万欧元(约合人民币6.72亿元)。

3月21日,IWS宣布通过其子公司IWS Fleet AS,与招商工业签订了2艘具备“步行工作(walk-to-work)”能力的风电运维船,新船将在2024年下半年交付,每艘造价为4800万美元。

IWS最初于2021年3月在招商工业订造了2+4艘Skywalker级风电运维船,其中前两艘计划在2023年一季度和二季度交付。在最新2艘备选订单生效后,IWS还有2艘备选船舶待生效,交付时间在2024年下半年。

据了解,该型船长90米,宽19.6米,设计航速13节,可为120人提供转运和30天以上的海上生活及作业支持。这是专门为海上风电场“步行工作(walk-to-work)”要求所建造的高规格船舶,采用创新设计,拥有灵活的任务设备,可以在安装、调试和运行/维护阶段处理海上风电场所需的各种任务。

新船采用柴电电力推进和直流母排配电系统,靠泊及操纵性能优异,可实现风场设备及备件的高效存储和运输;该船另配备直升机甲板、工作艇(子船)及艉部CTV接驳平台,人员运输及调配效率极高;同时本船配备DP2动力定位系统及3D波浪补偿传送舷梯及3D波浪补偿主吊,可实现严苛海况下的人员转运及风场维护作业,安全性能及工作效率远高于同类船舶。

该系列船将成为业界首批具有零排放作业能力的船舶,由康士伯海事公司设计。具备插入式混合动力电池解决方案,使用增压、太阳能电池和电池进行全电动操作,可以在零排放情况下运用长达6小时。未来,这些船舶可以以有竞争力的成本转换为零排放船舶,使用直接从海上风电场充电的电池运营,兼容生物燃料的内燃机,能够利用氨基燃料(燃料电池、氨气和甲醇)。

由于采用了先进技术,该型船的燃料消耗比目前正在建造的同类型风险运维船要低20%,每艘船每年能够减少超过1300吨二氧化碳当量的排放量。同时,新船也将是行业内首批具备“DNV SILENT”符号的船舶,其重点是尽量减少对水下海洋生物的影响。

其中,首制船“IWS Skywalker”号在今年1月开工,交付后将于2023年夏季开始执行与Dogger Bank 风电场的作业合同。这是全球最大的海上风电场,位于英国北海,计划在2023年至2025年间投产。

据了解,IWS是挪威船东Awilco的子公司。成立于1939年的Awilco专注于航运和海工资产的投资运营,拥有丰富的海工和航运业经验。
