DUTIES AND RESPONSIBILITIES
- Engineer and design mechanical scope for the Nikola Refueling Station, in coordination other Nikola Team members and NEL.
- Engineer and design all piping; and create specifications for piping, tubing, control valves, check valves, block valves, hoses, and other components to meet the requirements in NFPA 2, ASME B31.3, NFPA 55, NFPA 56, IFGC sections 704 & 705, local & state codes.
- Create the specifications for fabrication, assembly, and cleaning of high-pressure hydrogen piping and tubing assemblies, and in conformance with ASME B31.12.
- Coordinate with I&C Engineer on specifications of instruments exposed to hydrogen.
- Design equipment, piping, tubing accommodations for instrumentation identified by I&C engineer.
- Coordinate with the Electrical Engineer for location classifications (NFPA 500 or NFPA 497) and collaborate on design to assure compliance.
- Engineer, design and create specification for equipment which are compliant with the location classifications of the station.
- Create specification for safety valves to be installed on equipment and piping/tubing networks. Design to include calculations and consider the amount of hydrogen contained in zone being relieved. Where safety valves are provided as part of the vendor equipment, calculation will be performed to assure adequacy of the vendor pressure relief.
- Engineer and design purging system for safety of operation and maintenance, design should comply with NFPA 56 (standard for purging of flammable gas pipe).
- Engineer and Design hydrogen venting systems in accordance with CGA-G5.5 standards.
- Perform calculations for velocity and mass-flow though piping networks. Calculation should include depletion time for vessels. Leakage leak scenario models will be created to be coordinated with HazOps specialist for NFPA 68 and 69 analysis.
- Perform calculation to determine amount of hydrogen and energy in contained within selected boundaries for safety calculations.
- Engineer and design ventilation required by NFPA code. Provide calculations as part of the submittals to the Authority Having Jurisdiction.
- Coordinate with NEL to verify Hydrogen Generation Equipment Design & Operations in compliance with NFPA 2, Article 13
- Coordinate with NEL and other Nikola Team members to verify that design is in Compliance with NFPA 2, Article 10 Dispensing, and other relevant standards such as SAE J2601 and SAE J2799.
- Create technical specifications and design for equipment not provided by NEL, such as facility air compressor, water treatment equipment, waste water equipment, Control Room cooling and heating equipment, ventilation equipment, etc.
- Engineer and design foundations for equipment; pumps, compressors, fans, tanks, vessels, dispensers, concrete refueling pads, or other equipment required for safe operation of the Nikola Refueling station. Design must consider seismic conditions, thrust, and grounding (coordination with Electrical Engineer).
- Engineer and design, where needed, spill prevention containment dikes; and other containment required for hazardous materials.
- Specify and design hangers and supports required for tubing, piping, and vents (design to consideration of thrust and seismic).
- Mechanical Design to consider egress of personnel, high pressure jetting of hydrogen, flame impingement, access to panels, access for maintenance, etc.; coordinate with HazOps Specialist on modeling results.
- Mechanical Design to take into account the requirements identified in NFPA 1 and UBC.
- Mechanical Design should consider anomalies such as domestic water supply failure or supply pipe burst, flooding from storm run-off, high velocity wind, lightning strikes, seismic events, freezing weather conditions, and other nature caused events.
- Prepare Mechanical Engineer’s Final Report. This document must include descriptions of design, referenced Code Articles, all vendor cut sheets, calculations performed, safety factors,
- Coordinate with the other Hydrogen Infrastructure Team Members.
- Resolution of mechanical technical issues with vendors, contractors, building officials, customers, and Nikola team members.
- Train EIT Engineer.
- Degree in Mechanical Engineering from an accredited university.
- Ideal: Licensed Professional Mechanical Engineer in at least one state.
- Prior experience in design in hazardous classifications.
- Prior experience in coordination with Authorities Having Jurisdiction.
- Good Communication skills, with patience and pleasant characteristics.
- Believes in a sustainability and our vision
