In recent years, to prevent or mitigate atmospheric/marine pollution, regulations over vessels are being applied and tightened. And further technical innovation to preserve our beautiful sea and sky as well as enhanced development of diversified environmental equipment for vessels has also triggered a change with such a trend in engineering needs to repair vessels currently in service. Mitsubishi Heavy Industries, Ltd. (MHI) has integrated the 3D plant measurement technology practicalized at its nuclear power sector with the 3D CAD vessel design technique, actively promoting the engineering to repair vessels currently in service. This is an engineering method based on as‐built 3D CAD models of established piping plants reproduced as is on CAD, using a 3D laser scanner. This report explains specific efforts for implementation of the above.
