As CITGO’s On-Call Maritime Engineering Consultant for their northeast facilities, GEI performed an investigation and assessment of their South Portland, Maine Marine Terminal Facility for identification of the current condition and assessment of their immediate and long-term maintenance and repair improvement needs.

The project scope included inspection and evaluation of the fixed timber access pier and concrete berthing and mooring dolphins and their associated steel piles. The investigation and assessment included related structures including mooring cleats and bollards, fendering systems, and product hose tower support. Inspection services consisted of the above and underwater inspection/assessment of all elements with a Level I and Level II inspection and documentation of conditions.

The report developed from the investigation identified short-, medium- and long-term repairs at the site and was used directly by CITGO to procure contractor services to perform the repairs.

GEI has performed a wide range of services at this site for CITGO, including:

  • Design of modifications to the pier and ship gangway system. This included evaluation of site environmental criteria, vessel dimensions and freeboards, and limiting operating conditions for safe vessel access.
  • Performance of an annual hydrographic survey for documentation of berth depth for the CITGO facility. Berth was approximately 1,000 by 300 feet.
  • Design and construction phase services for tank foundation replacement.
  • Emergency recovery of storm-damaged pier building.
