ANSI API RP 2MOP-2010 (2021) PDF

Full title and description

St ANSI API RP 2MOP-2010 (2021) — API Recommended Practice 2MOP, "Marine Operations". This document provides recommended practices, requirements and guidance for planning, engineering and execution of marine operations related to offshore structures and associated systems, equipment and procedures. It is a national adoption of ISO 19901-6:2009 and was reaffirmed as an ANSI/API document in 2021.

Abstract

RP 2MOP/ISO 19901-6 gives requirements and guidance for the planning and engineering of marine operations for offshore structures. Topics include the design and analysis of components, systems and equipment; development and verification of procedures to perform operations safely; and guidance for modifications to existing structures (for example, topside module installation). The document is intended to reduce operational risk by standardizing methods, competencies, verification and documentation associated with marine operations.

General information

• Publication date: Original publication: July 2010 (1st edition). Reaffirmation / ANSI final action (R2021): January 4, 2021; API lists the document as reviewed/confirmed in 2021.
• Publisher: American Petroleum Institute (API) — national adoption of ISO 19901-6.
• ICS / categories: 75.180.10 (Petroleum and natural gas industries — offshore structures / marine operations).
• Edition / version: 1st edition (2010); reaffirmed as ANSI/API RP 2MOP (R2021).
• Number of pages: Approximately 180–185 pages in typical PDF/vendor distributions (vendor listing commonly shows 182 pages).

Scope

This recommended practice is applicable to marine operations for a wide range of offshore structures (steel and concrete gravity-base structures, piled steel structures and compliant towers, tension leg platforms, deep-draught floaters including spars, floating production units such as FPSS/FPSO, mobile offshore units, topsides and components, subsea templates, anchors, tendon foundations and associated mooring systems). It covers planning, analysis, equipment and procedural development for carrying out marine operations safely and is also applicable to certain modification activities of existing structures. It does not cover onshore fabrication-yard construction activities, routine in-service activities, drilling and pipeline installation, or diving operations.

Key topics and requirements

• Planning and engineering of marine operations: risk assessment, method statements and marine spread design.
• Design and analysis requirements for equipment and systems used in marine operations (lifting, transportation, mooring, positioning).
• Procedures, competencies and verification: personnel qualifications, training and documented verification/inspection steps.
• Management of change, documentation, testing and monitoring during operations.
• Guidance on modifications and installation of topside modules and other retrofit activities.
• Cross-referencing and alignment with related ISO/API offshore standards and errata/addenda (users should confirm the latest errata or addenda before implementation).

Typical use and users

Used by offshore operators, marine and offshore engineers, project planners, marine contractors, installation supervisors, HSE teams, surveyors, classification societies and regulators to develop safe, repeatable methods for marine operations and to incorporate industry best practice into company procedures, contractor specifications and training programs.

Related standards

API RP 2MOP is the API/ANSI national adoption of ISO 19901-6:2009 and is typically used alongside other API/ISO offshore standards (for example, other parts of ISO 19901, API RP 2T, RP 2SK, RP 2GEO, RP 2TOP and integrity-management related RPs). Users should check for any errata or addenda published for RP 2MOP and for cross-referenced standards.

FAQ

Q: What is this standard?

A: API RP 2MOP-2010 is an API recommended practice (national adoption of ISO 19901-6:2009) titled "Marine Operations" that provides guidance and requirements for planning and engineering marine operations for offshore structures.

Q: What does it cover?

A: It covers planning, engineering and safe execution of marine operations — including design and analysis of equipment and systems, procedural development, competency/verification, documentation and guidance for specific activities such as topside module installations and other modification activities. It excludes routine service activities, onshore fabrication-yard-only construction, diving and pipeline installation.

Q: Who typically uses it?

A: Offshore operators, marine contractors, project and installation engineers, HSE and assurance teams, surveyors and classification societies use RP 2MOP to establish consistent, auditable practices for marine operations.

Q: Is it current or superseded?

A: The original API RP 2MOP was published in 2010 (1st edition) and the national adoption/reaffirmation as an ANSI/API document was completed in 2021 (R2021). Users should confirm there are no later revisions, addenda or errata applicable to their jurisdiction or project before use.

Q: Is it part of a series?

A: Yes — RP 2MOP is part of the broader family of API/ISO standards addressing offshore structures and operations (ISO 19901 series and related API RPs). It is commonly used in conjunction with other API RPs that address geotechnical, topsides design, stationkeeping and integrity management topics.

Q: What are the key keywords?

A: Key keywords include marine operations, offshore installation, lifting & transportation, mooring & positioning, method statements, verification, ISO 19901-6 and API RP 2MOP.
