OTL has just completed a Deep Sea Mining Global Sizing Design for a confidential client. The targeted deep sea mine is located in water depth between 5000 m to 6000 m. OTL performed global sizing engineering to define the functionality requirement of the entire system, including the PSV (Production Support Vessel), the RALS (Riser and Lifting System), the pump and the subsea mining machine. Even though this is OTL’s first deep sea mining engineering project, OTL developed all necessary theories and engineering tools to perform complicated lifting analyses by air-lifting and pumping methods.
