DNV-ST-0378 Lifting Equipment Standard Explained
Offshore lifting compliance for modular spreader beams, lifting beams, lifting frames and below-the-hook lifting appliances.

DNV-ST-0378 is a recognised offshore lifting equipment standard used for the design, testing and certification of offshore and platform lifting appliances.
It defines technical requirements for lifting equipment used in offshore environments, where operational risks, dynamic loading and environmental conditions demand enhanced design verification.
This guide explains what DNV-ST-0378 covers, why it matters for offshore lifting, and how it applies to modular spreader beams and engineered lifting systems.
What Equipment Does DNV-ST-0378 Apply To?
The standard applies to offshore and platform lifting appliances, including below-the-hook lifting equipment used in marine, offshore wind, oil and gas, and heavy lift environments.
DNV-ST-0378 provides a framework to ensure lifting systems are engineered, manufactured and tested to meet the safety and reliability expectations of offshore projects worldwide.
What Does DNV-ST-0378 Cover?
DNV-ST-0378 addresses multiple aspects of lifting equipment design, certification, fabrication quality, traceability and proof load testing.
Structural Design Requirements
The standard defines load factors, safety factors and design methodologies appropriate for offshore lifting. Engineering calculations must demonstrate that structural members, including compression struts, end units and lifting lugs, can withstand the specified working load limits with appropriate safety margins.
For modular spreader beams, this includes verification across multiple span configurations.
Material Selection & Traceability
Material selection under DNV-ST-0378 requires certified material grades, mill certificates, full traceability records and clear identification marking.
Traceability ensures each structural component can be verified against documented material properties.
Fabrication & Quality Control
The standard outlines expectations for welding procedures, welder qualifications, inspection, non-destructive testing and dimensional verification.
Fabrication controls help ensure lifting equipment meets structural and quality assurance requirements before being placed into service.
Testing & Proof Load Verification
Proof load testing verifies structural performance under controlled conditions. Testing confirms that the structure behaves as predicted, no permanent deformation occurs, and welds and connections perform as designed.
Documentation & Certification
Offshore lifting equipment is typically supplied with engineering design calculations, material certificates, proof load test certificates, inspection reports, assembly drawings and user instructions.
Why DNV-ST-0378 Matters for Offshore Lifting
Offshore lifting operations carry higher risk profiles than many onshore lifts. Environmental exposure, vessel motion, wind loading and limited access for intervention increase the consequences of equipment failure.
Compliance with DNV-ST-0378 provides assurance that lifting equipment has been designed and verified for offshore environmental conditions, dynamic loading scenarios and high-consequence heavy lift operations.
For offshore wind developers and marine contractors, specifying lifting equipment built in accordance with DNV-ST-0378 helps reduce risk and supports project compliance requirements.
DNV-ST-0378 vs Other Lifting Standards
DNV-ST-0378 is not the only lifting standard in use globally, but it is widely recognised within offshore and marine sectors.
DNV-ST-0378
- Primarily offshore and platform lifting
- Strong documentation requirements
- Dynamic load considerations
- Commonly required for offshore wind projects
BS EN 13155
- European standard for non-fixed load lifting attachments
- Applicable to general lifting applications
- Often referenced for onshore use
- Commonly applied to below-the-hook lifting devices
While BS EN 13155 may be suitable for certain onshore lifting operations, offshore projects frequently specify DNV-ST-0378 due to its more detailed offshore-focused requirements.

How DNV-ST-0378 Applies to Modular Spreader Beams
Modular spreader beams are particularly relevant to offshore projects due to their configurable span capability, transportability and suitability for heavy lift operations.
When engineered in accordance with DNV-ST-0378, modular systems must account for structural verification across multiple span configurations, pin and connection strength, lug design, load transfer integrity, and offshore corrosion protection requirements.
Multisec Modular Spreader Beams are designed for demanding offshore and heavy lift projects, with certification and documentation packages available to support project requirements.

DNV-ST-0378 FAQs
Common questions about DNV-ST-0378, offshore lifting equipment and modular spreader beam compliance.
What is DNV-ST-0378?
DNV-ST-0378 is an offshore lifting appliance standard covering the design, manufacture, testing and certification of lifting equipment used in offshore and platform lifting applications.
What equipment does DNV-ST-0378 apply to?
It applies to offshore lifting appliances including spreader beams, lifting beams, modular lifting systems, lifting frames and other below-the-hook lifting equipment used in offshore environments.
Why is DNV-ST-0378 important for offshore lifting?
Offshore lifts are affected by dynamic loading, vessel motion, wind, corrosion and restricted access. DNV-ST-0378 provides design and verification requirements for lifting equipment used in these demanding environments.
Is DNV-ST-0378 different from BS EN 13155?
Yes. BS EN 13155 covers non-fixed load lifting attachments for general lifting applications, while DNV-ST-0378 is focused on offshore and platform lifting appliances with additional offshore-specific considerations.
Do modular spreader beams need DNV-ST-0378 compliance?
For offshore projects, modular spreader beams are often required to be designed and certified in accordance with DNV-ST-0378, especially when used in offshore wind, marine construction or vessel-based lifting operations.
What documentation is required for DNV lifting equipment?
Documentation may include design calculations, material certificates, proof load test records, inspection reports, assembly drawings, operating instructions and certification packages.
