DOC Neutralisation CAD

Project Overview
I need a CAD designer to model a subsea neutralisation mixing chamber and multiport discharge diffuser system in Autodesk Fusion 360. The system is part of a Direct Ocean Capture (DOC) process that captures CO₂ from seawater.
All materials, nozzle positions, and component specifications are provided below. You do not need to perform any engineering calculations — just model exactly what is specified.
Deliverables
Deliverable: Fusion 360 CAD Model (5 components + assembly)
All components modelled as separate files, then assembled in one top-level assembly.
Component 1: Neutralisation Mixing Chamber (V-401)
Vessel shell:
Horizontal cylindrical vessel with dished ends
Material appearance: Brushed stainless steel
Nozzles (8 total):
Acid inlet nozzle
Base inlet nozzle
Outlet nozzle
pH sensor nozzle + spare
Recirculation return nozzle
Drain nozzle
Vent nozzle
CIP nozzle
Include flanges and reinforcing pads as specified
Internal baffles (4):
Circular baffles
Alternating top- and bottom-mounted arrangement creating a serpentine flow path
Saddle supports (2):
Curved supports with baseplates
Include PTFE wear pads
Component 2: Discharge Pipeline (Line 401-C)
Pipe with vertical drop and horizontal run
Includes valves (simplified geometry):
Manual gate valve
Motorised ESD valve
Check valve
Additional isolation valve
Flanged connections throughout
Pipe supports at regular spacing
Component 3: Multiport Diffuser Manifold
Header pipe with inlet and end closure
Multiple angled outlet ports
Reinforcing pads at each branch
Removable nozzle inserts with sealing and retaining mechanism
Component 4: Seabed Base Frame
Structural frame using square hollow sections
Cross-members along the length
Pipe support cradles
Levelling feet
Pad eyes
Ballast pockets
Anti-scour mattresses beneath
Component 5: Monitoring Bracket
Vertical mast
Sensor mounting rail
Cable routing provision
Subsea junction box mounted to frame
Assembly Instructions
Base frame fixed at origin
Diffuser mounted onto frame
Pipeline connected to diffuser
Mixing chamber connected upstream
Monitoring bracket mounted
Umbilical cable routed along system

Important Notes
CAD does NOT require manufacturing tolerances
Do not deviate from provided specifications
Valve internals not required
Pipe supports can be simplified
Export all views as separate files
Ask if anything is unclear before modelling
Skills Required
Autodesk Fusion 360 (expert)
Mechanical / piping design experience
Attention to detail
