PROJECTS
Neptune LNG Buoy Servicing
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 several 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.
PROJECTS
Highline Bridge
Semper Diving & Marine was contracted to install driven pile foundations for a Replacement Railroad Bridge owned by the Massachusetts Bay Transportation Authority located in Somerville, MA. The need for the bridge to be placed on a Driven Pile Foundation was due to the underlying soft compressive soils at the bridge location. The Structure is now fully supported down to the Bedrock on an H-Pile Foundation.
