The Brooklyn Basin project revitalizes 65 acres along Oakland’s waterfront, transforming an industrial site into a mixed-use development. The new neighborhood offers more than 3,000 residences, public parks and trails, a new marina, and 200...
The aging marine oil terminal exceeded its design life and did not comply with the applicable seismic and berthing standard. The port, the ultimate owner of the marine structures, and the terminal operator undertook a project to replace the...
Founded in the early 1900s, Chevron’s Richmond Refinery produces gasoline, diesel, jet fuel, and lubricants. Since the refinery is located within the corporate boundary of the City of Richmond and on San Francisco Bay, it is subject to...
As part of a design competition, the James Corner Field Operations (JCFO) Team was selected to redesign the 3,000 ft long Navy Pier. The competition, spurred by the approaching 100th anniversary of the pier in 2016, set a goal to expand and...
The 1,900 ft long timber-framed approach trestle exhibited damage and deterioration due to aging and required repairs to maintain the function and structural integrity. SGH developed a comprehensive rehabilitation plan that allowed the...
Originally built in the 1950s, the timber terminal was becoming increasingly costly to maintain and was no longer considered fit-for-purpose for seismic and berthing requirements. Instead of embarking on an incremental improvement program,...
The existing fender systems at two berths of a refinery terminal were significantly deteriorated. SGH was the engineer of record for the design of a replacement fender system. We developed an innovative modular design that could...
During the spring of 2013, SGH investigated two hard tugboat allisions (collisions with fixed objects such as bridges or docks), at separate marine oil terminals. In both cases, the tugs were maneuvering their respective barges when they...
SGH was the engineer of record for the seismic retrofit design of two 450 ft long wharf structures that required strengthening to comply with the MOTEMS seismic performance standards for marine oil terminals in the state. SGH developed an...
The intermodal Quincy Commuter Boat Terminal provided access to the commuter ferry and historic U.S.S. Salem museum. The site consists of a bulkhead seawall and a reinforced concrete wharf. In November 2011, a water main located...
This paper presents findings from a research project on the development of a numerical framework to predict the collapse load of a wharf supported by corroded piles under gravitational loads. Data from a detailed marine investigation performed in...
Steeplechase Pier, located in Coney Island, Brooklyn, was damaged by Hurricane Sandy in late 2012. During reconstruction of the pier in 2013, the mooring “spud” of a construction barge failed and the barge rammed into the pier, seriously damaging it. Their article outlines the response to investigate this damage and develop repairs, details the challenges of completing an investigation that determined the condition of the piles, and discusses how the aggressive schedule to reopen the pier ultimately determined the chosen repair scheme.

This new PIANC reference will provide a set of recommendations to the global community involved in the initial design, analysis, or upgrade of marine oil and petroleum terminals. Potential users include owners/operators, port...
In current design practice any vessel at berth during an earthquake event is ignored. This is rationalized based on the frequency of vessel calls in combination with the infrequency of significant earthquakes and the long response...
For the seismic design of pier and wharf structures, there are multiple methodologies permitted for determining displacement demands. The current edition of MOTEMS and ASCE 61-14 permits use of an iterative substitute structure...
