Design Calculations & Drawings

• On-line leak sealing clamps

Details

Nautilus engineers provide innovative and efficient design and drawings of on-line leak sealing repair services in the form of sealing clamps. Majority of our sealing clamps are for the oil and gas industry and due to the severity of leaks on high-risk service pipelines, Nautilus engineers provides a 24 hour call service, ensuring that priority 1 sealing clamps have a design time of 1 day maximum.

• Tank Stairways (spiral)

Details

Nautilus engineers provide the specialised service of tank spiral stairway design and detailed drawing, ensuring structural integrity and efficient design in terms of space limitations. Nautilus’s helical stairway design has proven to be most efficient and commonly used by refineries for large storage tanks.

• Piping Systems

Details

Piping systems are designed in accordance with the ASME B series. Detailed models and 2D drawings as well as piping isometrics are provided by Nautilus Engineers.

 

• Vertical & Horizontal Pressure Vessels

Details

Nautilus Engineers provides design calculations for pressure vessels in accordance with ASME VIII Division 1 as well as PD5500. The use of contemporary pressure vessel software (Intergraph PV Elite) ensures code compliance for all our vessel designs. The 3D models as well as manufacturing drawings including weld map details are also provided.

• 3D Plant Design

Details

Plant layouts inclusive of the plant piping are modelled and detailed in 2D by our professional draughtees. Re-routing of plant pipelines as well as repairs are provided by Nautilus engineers. The intricate modelling of pipeline routes allows optimization of space and eliminates clashes with existing equipment.

 

• Scaffolding

Details

Nautilus Engineers provides scaffolding designs in compliance with SANS 10085, inclusive of manufacturing drawings and weld details.

 

• Inline Equipment

Details

Nautilus Engineers provides design and drawings of inline equipment such as pig launchers/receivers, static mixers and pipe sleeves.

 

• Heat Exchangers

Details

Heat exchanger intricate design calculations are performed using contemporary specialised software to ensure that the exchanger as well as its components are code compliant. Nautilus Engineers provides the design and drawing of both vertical and horizontal heat exchangers.

 

• Reactors

Details

Reactor design calculations are performed using contemporary specialised software to ensure that the reactor as well as its components are code compliant. The mechanical components of chemical reactors may also be analysed. Nautilus Engineers provides the design and drawing of both vertical and horizontal reactors.

• Pipe Support & Flexibility

Details

Nautilus Engineers provides design and drawings of pipe supports, pipe bridges and flexibility analyses between anchor points.

 

• Jacketed Vessels

Details

Nautilus Engineers provides design and drawings of vessel jackets. Calculations are performed to ensure the jacket meets the code compliant minimum thickness requirements for pressure envelopes and differential pressures between the vessel and components.

 

• Piping Isometrics

Details

Along with design calculations, detailed piping isometrics and material lists are provided by our professional draughtees.

 

• Structural Design

Details

Nautilus Engineers provides design of beams and building extensions. Although our expertise is not extensive in the civil engineering field, we are able to provide basic structural integrity calculations and code compliant drawings.

• Mixing Tanks

• Columns

• Lifting Beams

• P&ID's

• Tooling & Gearboxes

Finite Element Analysis

• On-line leak sealing clamps

Details

On-line sealing clamps are treated as pressure vessels for the purposes of design calculations. Finite element analyses are performed on the sealing clamps and their components to identify maximum deflections and stress concentrations.

 

• Pressure Vessels & Jackets

Details

Nautilus Engineers provides finite element analyses of pressurized vessels and their respective components. Stress concentrations are determined to ensure that the component is suitable for the designed pressures.

 

• Nozzle Loading

Details

Nautilus Engineers provides finite element analyses based on nozzle loadings for tank and pressure vessel nozzles.
