Rig Support Building, Oooguruk Island, Beaufort Sea, North Slope, Alaska

EEIS Consulting Engineers, Inc. (EEIS) was the prime consultant providing architectural/life safety design; civil, structural, mechanical process, mechanical HVAC, and electrical engineering; and instrumentation and piping design. The Rig Support Complex (RSC) housed mud mix pits, a grinding unit, associated pits, cementing operations, and dry storage. The facility was a 7,200-square-foot fabric building with seven truckable steel support modules that housed motor control centers (MCCs), boilers, HVAC units, compressors, mud lab/offices, and change room. EEIS also provided bidding support, procurement, submittal review, and on-site construction support.


The RSC was founded on precast concrete footings. The floor was composed of rig mats sitting on a gravel pad. Thermosyphons protected the RSC floor and footings. The rig mats were welded together; closure plates covered gaps between the mats to eliminate tripping hazards.

Drilling Warehouse, Oooguruk Island, Beaufort Sea, North Slope, Alaska

EEIS was the prime consultant providing architectural/life safety design and civil, structural, mechanical process, mechanical HVAC, and electrical engineering. The Drilling Warehouse was a 60- by 78-foot fabric building that housed dry storage for supplies, tools, and equipment. Mechanical heating and ventilation equipment was located on a mezzanine above an overhead door to maximize usable storage space on the floor. A self-supported, 2-hour firewall formed one end of the building, separating it from an existing maintenance shop. The wall was supported by W12x40 piles that cantilevered out of the ground to support the subframing of the wall.

Drilling Support Complex, Nikaitchuq Satellite Drilling Island, Beaufort Sea, North Slope, Alaska


EEIS was the prime consultant providing architectural/life safety design; civil, structural, mechanical process, mechanical HVAC, and electrical engineering; and instrumentation and piping design. The Drilling Support Complex (DSC) housed mud mix pits and dry storage.


The DSC was a 12,900-square-foot fabric building founded on steel beams attached to a precast concrete panel floor system. The floor was composed of precast concrete panels sitting on a gravel pad. Thermosyphons protected the DSC floor and footings. The precast floor panels were welded together. Joints between the panels were filled with rubber gaskets and sealants. A liner with a collection sump was installed under the building.


Five truckable steel modules with insulated wall panels were located next to the fabric building. The facilities included a boiler module, HVAC module, electrical module, fire pump module, and waste processing module. The modules contained all associated support and process equipment and systems. Structural design included pipe rack and pipe support design.

EEIS provided support for bidding, requisitioning, fabrication, and construction.
