Full title and description

ND 2-020201-015 — Rules for the classification, construction and equipment of mobile offshore drilling units and fixed offshore platforms. This regulatory document establishes classification symbols, survey regimes, technical documentation, structural and systems requirements (hull, stability, machinery, piping, electrical, automation, lifesaving and fire protection), and requirements for pollution-prevention equipment applicable to floating drilling units and stationary offshore platforms.

Abstract

ND 2-020201-015 (edition 2018) is a set of classification rules issued by the Russian Maritime Register of Shipping that consolidates technical requirements and mandatory survey procedures for mobile offshore drilling units (MODUs) and fixed offshore platforms (FOPs). The Rules reflect international recommendations (including the IMO 2009 MODU Code) and provide a comprehensive reference for design, construction, equipment, and in-service surveys to ensure safety, environmental protection and class compliance of offshore installations.

Scope

These Rules apply to the classification, construction, equipment and survey of mobile offshore drilling units (including self-propelled and non-self-propelled units) and fixed offshore platforms. They set out requirements specific to MODUs and FOPs while taking into account and implementing recommendations of the IMO MODU Code (2009) and relevant unified requirements and resolutions of classification societies and the IMO. The Rules cover items from hull structure and stability to lifesaving, fire protection, pollution prevention, electrical systems, automation (including dynamic positioning) and offshore operations safety assessment.

Key topics and requirements

• Classification principles, class symbols, scope and frequency of surveys (initial, periodical, intermediate and special surveys).
• Hull structural design rules, strength checks and finite-element model requirements.
• Stability and intact/damage stability criteria; procedures for inclining and stability calculations.
• Machinery, mechanical systems, lifting appliances and piping system requirements (design, materials, testing and inspection).
• Electrical power generation, distribution, control systems and requirements for hazardous-area equipment.
• Fire protection, detection and suppression systems; structural fire integrity and compartmentation.
• Lifesaving appliances, arrangements for embarkation/abandonment, davits, lifeboats and muster systems.
• Automation, dynamic positioning and systems with automation class notations; requirements for control, redundancy and monitoring.
• Pollution-prevention equipment, bilge and oily-water handling, and environmental protection provisions.
• Risk assessment, safety evaluation and criteria for acceptable levels of safety (QRA guidance and risk management).

Typical use and users

Primary users are classification society surveyors, naval architects, offshore engineers, shipyards building/modifying MODUs and platforms, owners/operators of offshore units, flag-state and port-state inspectors, regulatory authorities, and consultants preparing design documentation and safety/risk assessments. The Rules are used during design approval, construction, class surveys, conversions, major repairs and periodic inspections.
