NELSON has participated in the permitting, design, construction management, and start-up of numerous facilities both offshore and onshore. The projects have included: offshore drilling and production platforms; floating production systems; offshore receiving, processing and transshipment facilities; secondary and tertiary recovery facilities; production skids; quarters buildings; onshore wellhead, gathering and treatment facilities; compressor stations; pumping stations; pipelines; and power plants.
These projects have brought us significant specific experience in the following areas:
Design of Production Facilities of Various Configurations
- Large Multi-Platform Complexes
- Facilities using Fixed Steel and Concrete Structures
- Floating Production Systems (Converted Tankers, Tension Leg Platforms, Barge Mounted)
- Subsea Tiebacks to Fixed and Floating Facilities
- Conversion of Mobile Drilling Units to Production Service
Design of Facilities For Unusual Stream Conditions
- Heavy Crude (down to API 11)
- Sour Fluids (Gas Streams up to 25% H2S and 10% CO2)
- High Pressure Wellstreams (up to 25,000 PSIG SITP)
Large Offshore Electric Generation and Cogeneration Plants
- Large Power Plant Capacity (Experience through 40,000KW)
- Gas Turbine Generators with Waste Heat Recovery
- Gas and Diesel Engine Generators (Single and Dual-Fuel)
- Steam Turbines (Topping or Bottoming Cycle)
- High Voltage (34.5KV, 13.8KV and 4.16KV) Generation/Distribution
- Emergency Generators/UPS Systems (Rotary and Electronic)
