Wave Load Analysis now includes three (3) additional Wave Theories namely Fenton's Stream, Dean Dalrymple Stream and Solitary (Munk/McCowan) with the option for the user to input the wave order from 1 to 31 for Fenton's Stream and Dean Dalrymple Stream Theories. So, starting version 15.00, for Wave Load Analysis, the user has the option to select any of six (6) Wave Theories, namely, Airy's Linear, Stokes 5th Order, Cnoidal 5th Order, Fenton's Stream, Dean Dalrymple Stream and Solitary (Munk/McCowan).

Improved convergence routine for Cnoidal Wave Theory in Wave Load Analysis.

New feature is added to combine 4 Wind Loads with 4 Wave Loads simultaneously in Occasional Stress computation, useful to analyse offshore piping, partially above water level and exposed only to wind, and the balance under water experiencing only wave loading. With the inclusion of these load cases, CAEPIPE now has the ability to define 115+ load cases and Support Load Summary for 280+ load combinations.

Hydrotest Stress evaluation is now added for EN 13480-3 (2024). This Hydrotest Stress evaluation can be seen through CAEPIPE Results Window > Results > Results... > Sorted Stresses and CAEPIPE Results Window > Results > Results... > Code Compliance.

New feature is added to use "Restrained" equations for above ground piping located between Intermediate Anchors for piping codes ASME B31.4, ASME B31.8, ASME B31.12 Pipeline Systems, EN 13480-3 and CSA Z662. This can be performed by defining PROXY soil and assigning the same to the "Restrained" piping sections. For further details, refer to the Section titled "Soil" in CAEPIPE Technical Reference Manual.

For cohesive soil, if the soil strength is specified as greater than 250 kN/m2 (0.25 MPa or 250 psi) and the resulting adhesion factor is calculated to be less than 0.211, the system internally applies a minimum value of 0.211 for adhesion factor.

A new feature has been added to the Soil dialog allowing users to input Cushion Density. When provided, the cushion’s weight is now computed and included in the analysis.

New feature is added to assess piping loads applied to nozzles on Positive Displacement Pumps in accordance with API 676 (2022). For further details, refer to the Section titled "Pump" in CAEPIPE Technical Reference Manual and the Section titled "API 676" in CAEPIPE Code Compliance Manual.

New feature is added to the Generate command. This command now supports duplicating layouts created with Absolute Coordinates. As part of this enhancement, the release also automatically updates the node numbers in the “Connected To” field within the Support Data types to maintain proper connectivity, if input.

A new feature has been added to prevent users from finding spring hangers with a specified type and replacing them with spring hangers without a type in the Find and Replace command. In other words, the Type field cannot be left blank.

A new feature has been added to prevent users from inputting Operating Temperatures, Peak Temperature and Reference Temperature below -460 deg. F (= -273.13 deg. C or 0 Kelvin).

A new feature has been added to display a warning message when the selected analysis code differs from the analysis code in the material library.

A new feature allows users to select the Flange Equivalent Pressure method as “ASME Class 2 (2023)” or “EN 13480-3 (2024)”. This option can be accessed via Layout Window > Option > Analysis > Misc.

New feature is added to print Sorted Stresses results of "Operating Stress for NDE" and "Operating Stress for Impact Test" to CSV and TXT file when the option is Turned ON.

New feature is added to print Minimum & Maximum Displacements results for the selected load cases when the Displacements results are turned ON through Print Dialog.

New feature is added to close the list window and change focus to Layout Window when the commands "Refine Nodal Mesh", "Refine Branches" and "Reverse & Paste" are used.

The maximum file path length has been increased from 80 to 256 characters, allowing batch run paths to be up to 256 characters long.

A new feature has been added to create a temporary file in the Local User directory, enabling support for long file names in the PCF file and avoiding write access issues.

New feature is added in CAEPIPE 3D+ for PCF to transfer LAPJOINT-STUBEND as a Flange or Pipe by modifying the config_pcf.ini file. For details, refer to the Section titled "CAEPIPE 3D+ for PCF" in CAEPIPE 3D+ User's Manual.

The following new features have been added to "CAEPIPE 3D+ for PCF" to enable smoother data transfer:

• TAB characters and BLANK lines are now skipped during processing.

• For CROSS components, the BRANCH1-POINT can be calculated using BRANCH2-POINT and CENTRE-POINT data when it is missing.

• For CROSS components, the BRANCH2-POINT can be calculated using BRANCH1-POINT and CENTRE-POINT data when it is missing.

• For TEE components on the run side, the END-POINT can be calculated using the other END-POINT and the CENTRE-POINT when one END-POINT is missing.

When Continuous Rendering mode is enabled via Main Frame > File > Preferences, users can temporarily switch between Rendered and Line views using Graphics Window > View > Render or Do Not Render.

Rendering of jacket piping and jacket connections (Spiders and Jacket End Caps) has been improved.

Bug Correction: For API 661 Qualification, the allowable column was shown as "NA" when the Nozzle Diameter is 4" (100 mm).

Bug Correction: Printing the Equipment Qualification Report for API 610 to CSV and TXT file was issuing Access Violation at Random.

Bug Correction: Sorted Stresses result is not displayed for EN 13480 when the entire layout is buried below the soil.

Bug Correction: When a Relief Value Loading dialog was used more than once with a different Force Spectrum Name input, then it was using the Time Function data created for the first time from the back end to generate the new Force Spectrum data.

Bug Correction: Wave Load Case is turned OFF when Mean Sea Level is input as zero.

Bug Correction: Incorrect criterion value in Automatic Wave Theory selection caused Stokes Theory to be excluded for part of its valid regime.

Bug Correction: Selecting "Dynamic Susceptibility" results was issuing "Access Violation" when the Pipe Material Density is input as 0.0.

Bug Correction: Tensile Strength values were missing in the Material Library file B313-2024.mat.

Bug Correction: When selecting a material from a library file with a version earlier than 10.60 that uses an analysis code other than B31.1, B31.3, B31.9, Z183, Z184, or Z662, and applying it to a model whose analysis code is one of the codes listed above, the Tensile Strength value was incorrectly assigned to the Yield Stress field. For example, when selecting a material from the library file “EN 13480-2012.mat” for a layout using the analysis code “ASME B31.1 (2024)”, the system incorrectly mapped the Tensile Strength value to the Yield Stress value.
