PROCESS & OPERATING PHILOSOPHY
Feed, intermediate, finished-product, water and chemical storage. The operating sequence, recycle paths, start-up/shutdown cases and normal/turndown behavior are defined before equipment finalization.
PROCESS EQUIPMENT
Storage Tanks
Atmospheric and low-pressure tanks engineered for product, operating cycle and site loads.
MAIN EQUIPMENT & PACKAGE LIMITS
Fixed/floating roof tank, shell, bottom, roof, nozzles, vents, seals and access. Materials, design margins, maintainability, isolation, access, lifting and spare philosophy are coordinated with the approved operating cases.
CRITICAL DESIGN INPUTS
Design/operating cases, fluid properties, corrosion allowance, materials, nozzle loads, wind/seismic data, transport limits, insulation and maintenance clearances.
ENGINEERING DELIVERABLES
Sizing, API calculations, drawings, settlement allowances, inspection and test package. The package also includes line/equipment lists, relief and utility summaries, layouts or 3D interfaces, vendor-document requirements, inspection plans and commissioning inputs as applicable.
AUTOMATION, SAFETY & HSE
Code-compliant relief interfaces, access and lifting provisions, inspection hold points, material traceability, qualified welding, NDE and pressure/leak testing.
APPLICATIONS & PERFORMANCE BASIS
Refineries, terminals, chemical plants and utility systems. Capacity, product quality, consumption and emissions commitments are confirmed only after the representative feed and project Design Basis are approved.
CODES, STANDARDS & QUALITY BASIS
API 650/620/2000, NFPA and local seismic/wind codes. The contractual code basis is selected by destination and client specification. ASME/API/TEMA, EN/DIN and GOST/EAC requirements are not mixed without an approved code-equivalency and authority review.
CONTRACTUAL CODE BASIS
API 650/620/2000, NFPA and local seismic/wind codes.
