The project required tying together 30 Conex containers stacked to form an enclosure around the drilling rig on the drilling platform. EEIS Consulting Engineers, Inc. (EEIS) provided design management and structural engineering, as well as assistance in procuring some items. The containers were stacked four high and supported a 40-foot-high by 20-foot-diameter fabric structure to shelter the rig derrick. The platform was elevated 14 feet above the tundra, which exposed it to large wind loads. The drilling platform could not take any uplift, so EEIS designed horizontal and vertical connections for the Conex containers and designed cross bracing between them so that there was no net uplift on the platform. The project also included design of a cantilevered monorail hoist to lift materials from the ground to the platform.
EEIS designed a 12-foot-wide, 70-foot-long, three-story-tall Cutting Catch and Pumping Module. The module was mounted on a trailer so that it could move with the rig. The module was built to receive, condition, and transport drill cuttings at high flow rates. EEIS was the prime consultant and was responsible for layout/life safety design; structural, mechanical HVAC, mechanical process, and electrical engineering; and piping design. Russian and ATEX code compliance was required as part of the project.
EEIS provided structural engineering for a sled equipped with a drilling tower. The sled had walls and a roof and functioned as a portable test drill vehicle. The project consisted of a 10- by 9-foot upper tower that was 40 feet tall and a 10- by 9-foot lower tower that was 15 feet tall with tie-off eyebolts for fall restraints. Overturning was a significant concern; the upper tower depended on lower tower and equipment weight to resist overturning. The upper tower was removed when not in use.
This study evaluated whether it would be feasible for the Colville Tribal Federal Corporation (CTFC) to take over distribution of gasoline and diesel to its seven gas stations. The study considered the feasibility of building a new tank farm, purchasing fuels directly from refineries, transporting the fuel by rail to the tank farm, and transporting the fuel by truck from the tank farm to the CTFC stores. The study included preparing a conceptual design of the new facility, estimating costs, and developing a feasibility analysis.
EEIS designed a 3-inch-high-pressure injection line from the M-I SWSACO Waste Injection Facility at the ConocoPhillips Alaska Kuparuk Pad 1B to Wellheads 5 and 6. The injection line allowed for a future connection to Wellhead 10. The line was rated at 10,000 pounds per square inch (psi) and -40 degrees°F. It was insulated and suitable for sour gas applications. Line relief and instrumentation were specified. Deliverables included Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), process flow calculations, pipe stress analysis, electrical drawings, and piping layout as an isometric drawings with material takeoff.
EEIS provided the architectural/life safety design and structural engineering for a 1,600-square-foot modular office for Doyon Drilling. The office consisted of four steel-framed modules bolted together. The structure was designed for a 3-pound-per-square-inch (psi), 70-millisecond (ms) blast criteria. The offices were supported on a steel frame above the Casing Complex for the rig.
