Puerto Rosales, Argentina
Otamerica, New Crude Oil Exports Jetty
Scope/Solutions
In 2023, Oiltanking Ebytem, a subsidiary of Otamerica, the world’s second largest fuel storage company, retained SGH to provide peer review services for the design and engineering support during construction of their new crude oil exports jetty in Puerto Rosales, Argentina. With a water depth of 18 m, the pier is capable of receiving Suezmax tankers on the exterior berth and Aframax and Panamax vessels on the inner berth.
Oiltanking Ebytem executed an engineering, procurement, and construction (EPC) contract. The jetty’s structures consist of large concrete pilecaps supported by 1 to 1.2 m dia. drilled shafts installed in silty sands. SGH peer reviewed the design for the jetty, featuring:
- A 1.8 km long access trestle connected to a double berth pier, forming an “L” in plan
- The trestle constructed with an array of 36 m long pipe galleries supported on pile bents
- An arrangement of strategically placed breasting and mooring dolphins, a service platform, and a loading platform, interconnected with walkways
- Support and conveyance for 2 to 20 in. dia. pipelines
- A loading platform with two marine loading arms on each side
SGH also provided engineering support during construction, which was challenged by:
- Silty sands that required pile driving analysis and crosshole sonic logging testing during the installation of drilled shafts and accomplished with two jacking platforms deployed to the site
- Staged construction related to placing large precast reinforced concrete elements and marine fluctuations due to the open sea exposure and semidiurnal tidal cycles
