HYTHE LATERAL LOOP NO.2 (HLL2)
Surerus Murphy Joint Venture (SMJV) was contracted by TC Energy to act as prime contractor for the construction of the Hythe Lateral Loop No.2 Pipeline Project. The project involved the construction of 14km of NPS 24 pipeline on predominately agricultural land, located approximately 10km northwest of the Town of Hythe, Alberta.
Project construction commenced on August 1, 2018 and was mechanically complete on October 14, 2018. The workforce had a peak of 214 personnel and were locally housed in both Hythe and Grande Prairie
Project challenges included construction work within sensitive environmental areas, including the presence of western toads, multiple locations of beaver habitat and noxious weeds located on the route. These challenges were successfully mitigated through comprehensive planning and construction management.

SMJV’s scope of work included the installation of inline inspection facilities (one launcher and two receivers), other prefabricated valves and assemblies and buoyancy control – both saddle bags and screw anchors. SMJV provided hot tap support to TC Energy.
