Derrick Posts - Deck Machinery and Hull Equipment
Derrick posts are fixed, load-bearing ship structures that support cargo derricks, booms and associated rigging. Usually fabricated from welded marine-grade steel, they transfer lifting and operational loads into reinforced deck and hull structures.
ProShipWorks provides end-to-end support to source and supply Derrick Posts for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Design and fabrication are generally governed by the vessel's classification-society rules for hull structures and lifting appliances. Applicable requirements may include ILO Convention No. 152, flag-state lifting-appliance regulations, approved welding procedures and certified structural materials. |
|---|---|
| Class Approval | Design drawings, load calculations, materials, welding, inspection and load testing may require approval or survey by the vessel's class society, such as DNV, ABS, Lloyd's Register, Bureau Veritas or ClassNK, according to vessel class and flag requirements. |
Installation, Maintenance & Safety Information
| Installation Notes | Install only to approved structural drawings. Align the post and fittings with the derrick geometry, weld using approved procedures, provide specified deck and under-deck reinforcement, perform required NDT, restore protective coatings and complete proof-load testing before service. |
|---|---|
| Maintenance Tips | Inspect welds, foundations, brackets and attachment points for cracking, deformation, corrosion and coating failure. Check drainage and internal corrosion where accessible; repair defects under an approved procedure and maintain lifting-appliance inspection records. |
| Safety Notes | Do not operate above the approved safe working load or outside permitted boom angles. Isolate the lifting system before inspection, restrict access during load tests and lifting operations, and investigate any distortion, cracking or abnormal movement before reuse. |
