The DNVGL-ST-N001 (now often referred to as DNV-ST-N001) is the industry-standard PDF for the design and planning of marine operations and marine warranty survey (MWS) requirements. Key Overview
Purpose: It ensures that risks during temporary phases of offshore projects—such as transport, installation, and removal—are reduced to an acceptable level.
Scope: The standard covers offshore assets including wind farms, subsea cables, and oil and gas infrastructure.
Replaces Legacy Codes: It harmonized and replaced several older guidelines, including the legacy Noble Denton 0001/ND, 0027/ND, and DNV-OS-H series. Core Content of the PDF
The document is extensive (often over 500 pages) and typically includes the following technical sections:
Planning and Execution: Requirements for operational procedures and safety management.
Environmental Conditions: Guidance on metocean criteria (wind, waves, and currents) for safe operations.
Load-out and Transportation: Standards for securing cargo and voyage planning.
Lifting Operations: Specific criteria for offshore lifting and lowering, including dynamic amplification factors (DAF). dnvglstn001 pdf
Subsea Operations: Requirements for installing pipelines, risers, and cables. How to Access
Official Source: The full, binding PDF version is available through the DNV Standards Wizard on the MyDNV customer portal.
Digital Integration: The digital "Standards Wizard" allows users to filter the 500+ page document to extract only the sections relevant to their specific asset or operation type.

The DNV-ST-N001 (formerly DNVGL-ST-N001) is the global industry standard for marine operations and marine warranty. It provides a comprehensive framework of technical requirements and guidance for the safe planning, design, and execution of offshore operations. Core Purpose and Scope
This standard addresses marine operations occurring during the development or decommissioning of offshore assets, or when objects are moved by water. Key Operations Covered: Load-out: Moving structures from land to a vessel.
Construction Afloat: Building or assembling assets while in the water. Voyages: Transporting offshore structures over water. The DNVGL-ST-N001 (now often referred to as DNV-ST-N001
Installation/Removal: Placing or decommissioning assets like offshore wind farms, subsea cables, and oil and gas platforms.
Asset Types: It covers the entire value chain, including fixed steel and concrete platforms, FPSOs, subsea pipelines, risers, and offshore wind turbines. Technical Focus
The standard spans nearly 800 pages and combines legacy expertise from DNV, GL, and Noble Denton.
Marine Warranty Survey (MWS): It establishes the requirements for MWS approval, which is often essential for insurance purposes.
Design and Planning: It defines load cases, acceptance criteria, and principles for structural design and operational procedures.
Risk Control: Following the standard helps manage project risk and provides assurance to stakeholders and underwriters. Latest Updates (December 2023 / February 2024)
DNV recently published a substantial revision to ensure the standard remains relevant for the energy transition. Noble Denton marine services - Standards Wizard - DNV
DNV-ST-N001 is the industry-standard technical document for marine operations and warranty, covering the design and planning for transporting, installing, and removing offshore assets. Updated in February 2024, the comprehensive standard addresses environmental criteria, load-out, lifting, and subsea asset installation.
