Self elevating platform
	DKK107 is equipped with high-performance elevating apparatus for offshore operation. In addition to its capability as standard the SEP, there is ability of loading platform with large crane (e.g. 500t lift capacity) and long bladelike materials. This SEP is suitable for installation of offshore wind turbines (OWT) or maintenance of it. Of course, the casing rotator frame and pile driving rig can be mounted on it at your convenience.	Safe, efficient, and proper operation is required in diversified construction works, especially port and offshore construction under the severe environmental conditions such as weather, sea, and terrestrial phenomenon. Standard SEP fulfills the needs and brings various works in action. The casing rotator frame and pile driving rig can be mounted on. Furthermore, during construction of the offshore wind-power plant, SEP Mutsu and SEP Aso can be used as materials supply barge of other SEP work.
