A 24" offshore gas pipeline tied into Israel's existing 30" national transmission system via hot-tap, PLEM, and rigid spool arrangement. Onsite project management and local execution support across the full onshore execution chain.
Project overview
The Hadera Hot-Tap Pipeline (HHTP) project connects a new 24" offshore pipeline of approximately 5.35 km to an existing 30" offshore gas transmission line via a hot-tap connection, PLEM (Pipeline End Manifold), and rigid spool arrangement. The pipeline lands at Hadera through a trenchless landfall crossing and connects onshore toward existing infrastructure.
The project combines offshore pipeline installation, hot-tap interface works on a live national gas transmission line, trenchless shore crossing, onshore pull-in operations, and pipeline pre-commissioning — executed by a multi-national contractor team operating within Israel's regulatory and operational environment.
The technical scope itself is mature offshore practice. What makes the project demanding is execution synchronization: interface density, sequence dependency, and continuity across multiple phases and contractor scopes operating simultaneously.
Hadera onshore worksite — operational base for the offshore campaign
Role of A&S Global
Project involvement began through Maagan, where A&S Global's founder served as Project Manager across early execution phases — site establishment, HDD landfall works, onshore pipeline welding, the onshore pull-in operation, and the subsequent offshore support and tie-in activities.
Engagement with A&S Global directly began at the pre-commissioning stage of the project — built on site knowledge, established contractor relationships, and continuity carried forward from the earlier phases.
Execution phases
Setup and ongoing coordination of the Hadera onshore worksite that served as the operational base for the offshore installation campaign and associated subcontractors.
Site coordination, local execution support, logistics interfaces, contractor support, operational continuity, and worksite readiness throughout the campaign.
Trenchless landfall crossing executed by A-Hak. Local site coordination, contractor support, and interface management between the offshore pipeline works, the landfall area, and the onshore worksite.
Onshore pipeline welding spread executed by Real Engineering. Site-level coordination and interface support between the welding contractor, local support teams, and broader project operations — bridging the HDD exit, onshore facilities, and tie-in readiness for later commissioning.
Pipeline pulled to shore directly from the pipelay vessel Seminole — a continuous integrated marine-to-shore operation rather than a separated installation and pull sequence. Onshore-side coordination connecting the offshore marine operation with the onshore worksite and HDD exit interface.
One of the highest-interface-density moments of the project — weather, tension management, alignment tolerances, and contractor synchronization all converging within a narrow operational window.
Pipeline pre-commissioning works planned within the project — flooding, cleaning, gauging, hydrotesting, dewatering, drying, and nitrogen preservation. Onsite coordination, contractor interfaces, and local execution continuity.
Project participants
Value delivered
In multi-contractor offshore projects, the most common failure mode is interface breakdown between phases — “nobody remembers why this was done,” “that was another contractor,” “design doesn't match field reality.” Continuity across the execution chain is what closes those gaps.
Single point of project knowledge spanning early site works through pre-commissioning — a perspective rarely held by any other party on the project.
Established working relationships across all major project participants — international main contractor, specialist subcontractors, and the local support contractor.
Practical understanding of buried infrastructure realities, as-built conditions, unresolved field issues, and how the worksite evolved across phases.
Practical bridging between international project execution standards and the local operational realities of working in Israel — Hebrew-language interfaces, local authorities, and supply chain depth.
The HHTP project reflects A&S Global's approach to complex infrastructure execution in Israel — bridging the gap between international project requirements and local execution realities, from worksite setup through onshore pull-in and pre-commissioning support.
