Neptune LNG Pipeline

Since 2012, Semper has been the lead service provider of the Neptune Deepwater Liquid Natural Gas Pipeline located in 270 feet of water 20 miles East of Boston in Massachusetts Bay. 

Over the past 5 years, Semper has provided dozens of visual and acoustic inspections through both ROV and AUV robotics as well as our divers. Repairs to the pipeline include pressure washing by both ROV and divers, sacrificial anode replacement, concrete articulated mat replacement, and more.
