Docks & Terminals

Provided FEED and layout of operator building location, detailed design of support structure, and interface with building vendor and fabricator/installer throughout the project. Leveraged laser scan and 3D model to interface with existing structure and finalize layout. Located obstructions to facilitate prep/demo work, minimizing dock downtime. Set access levels similar to hose tower to minimize stair additions. Performed structural analysis and design of new gangway tower and existing support structures for new loads.

Provided FEED selection and layout of vertical track gangway, detailed design of support structure, and interface with gangway vendor and fabricator/installer throughout the project.  Leveraged laser scan and 3D model to interface with existing hose tower access system and minimize footprint.  Located obstructions to facilitate prep/demo work, minimizing dock downtime.  Provided access platforms as required.  Performed structural analysis and design of new operator building support structure and existing deck for new loads.

Keystone provided engineering design support services and developed a Phase II quality total installed cost estimate for the Dock Electrical Upgrade Project. The project goal included increasing reliability and improving maintenance at the refinery. Keystone's scope of work included installing new 5KV transformers for the dock and a new Main-Tie-Main (M-T-M) breaker system for the electrical feed to the refinery cooling water pumps.

Additionally, the scope involved the installation of two 5KV switch racks, the replacement of seven 480v motors on cooling water pumps with new 4160v motors, and the installation of new raceway and cable to interconnect all new equipment.

As part of a significant upgrade effort at the bulk terminal facility, Keystone provided engineering, design, automation programming, and on-site support. Keystone scope included the following: electrical load studies, specifications for electrical power system equipment, design of electrical and control systems for four new stacker gantry units and existing Krupp trailer-tripper unit, design of two complete substations, and design of electrical and control systems for reconfiguration of two existing yards, including cable tray, power systems, lighting, and grounding.

Additionally, the scope of work included electrical one-line diagrams for demolition and the new facility power distribution network, construction cost estimate and Primavera schedule, control philosophy and sequence of operations for the entire facility, and programming for all new PLCs and revise programming for all existing to remain PLCs.

Keystone designed new breasting and mooring dolphins at four of the facility’s docks. The scope of work included site inspection of the marine terminal, structural design of new mooring/breasting Monopile, SACS Modeling, Optimoor Mooring arrangements, permitting requirements for new
structures to include correspondence with Corps of Engineers and all 3rd party agencies, review soils geotechnical data, and bathymetric/hydrographic surveys.

Additionally, Keystone’s work scope included surveying the existing docks to locate fender lines and existing marine structures, establish horizontal and vertical control at the site, coordinate with subcontractors, prepare permit drawings, layout drawings, structural drawings, and demolition plans.

Keystone provided civil/structural engineering and design services for the design of new fenders for a dock. Keystone's scope of work included developing the design basis for handling vessels at the dock and the development of mooring plans and requirements for the usage of vessels at the dock. Keystone produced a complete structural model using SACS software for the loading platform as well as the upriver and downriver dolphins and checked new fender reactions. Construction packages were designed and drafted for new mid fenders on the loading platform and upriver/downriver dolphins.

Keystone provided civil/structural engineering and design services for the Dock Optimoor Analysis and Structural Assessment Project. Keystone’s scope of work included gathering drawings and information on existing structures and fenders, preliminary design basis and ship arrangement plans, and developing Optimoor models for the dock and run cases.

The project included three upriver/downriver breasting dolphins, a loading platform, and upriver/downriver mooring dolphins. The SACS models involved modeling dolphins using EDI SACS Marine Structural Analysis Program as well as modeling soil and piling. Additionally, the project scope included dynamics runs to develop dolphin spring, in place sizing to check dolphins with modified system spring, and check joints for API punching shear.
