据英国《船坞及港口管理》1978年4月号报道,新西兰修建莫伊天然气田第一号平台时,采用了与高压空气喷射提升器相结合的水下打桩锤,此锤能克服淤泥线以下24～39米密实沙层的阻力。一号平台是在107米深的海中建造起来的,需打边桩24根。由于罕见的塔斯曼海风暴和不利的海底土壤条件,平台的竣工日期几乎推迟了两年。水下打桩锤的好处是不受恶劣天气的影响,能伸入打桩的导架内进行工作。每打进海底一英尺,需要400～ According to the United Kingdom “Dock and Port Management” in April 1978 reported that the construction of New Zealand Moye gas field No. 1 platform, the use of high-pressure air jet lift combined with underwater hammer, the hammer can overcome the mud line below 24 ~ 39 meters dense sand resistance. One platform is built in the sea of ​​107 meters deep, need to fight the pile of 24. Due to the rare Tasman Sea storm and unfavorable seabed soil conditions, the completion date of the platform was almost two years delayed. The benefits of underwater piling hammer is not affected by the bad weather, can be inserted into the guide piling work. Each foot into the sea, you need 400 ~
