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...
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...
SGH was the engineer of record for the anchorage design and construction planning associated with the installation of new, quick-release mooring hook assemblies at several marine oil terminals in California. For these projects, we developed...
With modular construction, CNRL was able to expand the Delayed Coker Unit at their Horizon Oil Sands site while minimizing downtime during construction. The project utilized supermodule structures constructed or assembled from smaller modules...
This paper will describe a $16M rehabilitation program of a 1960’s vintage, reinforced concrete marine oil terminal at the Port of Long Beach intended to enhance the performance and operational life of this critical infrastructure. The...
Berthing velocities for design of fender systems have long been based on old and incomplete data, often from studies dating as far back as the 1950s. Both PIANC and MOTEMS continue to use values based on these old datasets in their...

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...
A 1960s era California marine oil terminal was determined to be a possible collapse hazard in a major earthquake. Rather than replace the structures with an estimated construction cost of over $100M (plus millions more in operational...
Historically, the seismic design of topsides structures like marine loading arms and hose towers has been done inconsistently and to a wide array of design codes and requirements. The root of this problem has been a forced reference...
Overhead protection (OHP) structures are used by major oil operators and government agencies in terrorist affected areas to protect facilities housing their personnel such as office facilities and dining facilities. Structural design of OHP...

Waterfront Facilities Inspection and Assessment supplies engineers with guidelines and tools for inspecting and evaluating the condition of waterfront structures located in seawater and freshwater environments. Inspections are...
