What Davit Arm Calculation (Moss Method) — Vessel Maintenance Excel calculates
Davit Arm Calculation (Moss Method) — Vessel Maintenance Excel is an Excel-native engineering calculation tool built by 3D-LABS for mechanical, design, and equipment engineers working with pressure equipment, rotating machinery, and mechanical systems. It is used for sizing pressure vessels, heat exchangers, flanges, bolts, and other mechanical components. Every input is labelled and every output is traceable — the sheet is designed to be checkable, not a black box.
Codes and standards followed
Davit Arm Calculation (Moss Method) — Vessel Maintenance Excel follows industry-standard Mechanical Engineering codes including ASME VIII Div 1 & 2, ASME B16.5, TEMA, API 660, HEI, EN 13445. Each formula is cross-referenced to the applicable code clause so your reviewer can trace calculations back to the standard.
If your project requires a different code base (e.g. converting an IS-code sheet to an ASME basis), we can produce a code-variant edition on request. Contact info@3d-labs.com for a variant quote.
