The majority of existing offshore wind turbines are built on monopile foundations, space-frame foundations (jackets) will be the foundations of choice for most new applications. This will enable wind turbines to be deployed at greater water depth, further from the shore leading to higher wind speeds and increased potential generation capacity per swept area.However, current manufacturing techniques for turbine jackets are non-serial and particularly labour intensive, a direct consequence of the manual fabrication methods typically used.The LaserJacket project will assess three innovative thick-section (>60mm) laser welding techniques, which have a high-productivity, are cost-effective, and suitable for the manufacture of thick-section turbine jackets. We will subsequently, down-select a single welding technique which will be further developed and demonstrated for applicability to offshore wind turbine jackets.

大多数现有的海上风力涡轮机都建立在坚固的基础上，空间框架基础（导管架）将成为大多数新应用的首选基础。这将使得风力涡轮机能够部署在更大的水深处，远离海岸，从而导致更高的风速和增加的每扫掠面积的潜在发电能力。然而，当前用于涡轮机护套的制造技术是非连续的并且特别劳动密集型的，LaserJacket项目将评估三种创新的厚截面（> 60 mm）具有高生产率的激光焊接技术是成本有效的，并且适用于厚截面涡轮机套的制造。随后，我们将向下选择一种焊接技术，该技术将进一步开发并证明其适用于海上风力涡轮机导管架。
