Rules & Guidelines

Noble Offshore Technical Guidelines and Rules

The Noble Offshore Technical Guidelines and Rules are developed through extensive research and development, the know-how and experience of our engineers and the close feedback of our worldwide network of technical experts. Our Guidelines and Rules represent the current state of scientific development and industry practice.

 Self-Elevating Platforms – Guidelines for Elevated Operations

These guidelines will be used by Noble Offshore for the assessment of self-elevating platforms in the elevated condition. They address:

  • General feasibility studies, including optional checks for punch-through resistance and fatigue; such studies may result in a Statement of Compliance
  • Assessment for specific locations; such studies may result in a Certificate of Approval.

 Guidelines for Loadouts

These guidelines have been developed for the loadout of items including offshore jackets, SPAR sections, modules, bridges and components from the shore onto floating or grounded barges and ships.

 Concrete Offshore Gravity Structures

These guidelines have been developed Noble Offshore for the marine aspects of construction, towage and installation of offshore concrete Gravity Base Structures (GBS) with a deck.  They are intended to be applicable to deep draft structures, where much of the construction work is carried out afloat, as well as shallower draft structures where the construction of the GBS can be essentially completed in dry dock.

0016/ND Rev 6 – 06 December 2010 Seabed and Sub-seabed Data for Approvals of Mobile Offshore Units

These guidelines describe  the seabed and sub-seabed data required by Noble Offshore to assess the suitability of locations for self-elevating (jack-up) platforms, anchor installation and performance assessments.

 Guidelines for the Approval of Towing Vessels

These Guidelines are intended to lead to an approval by Noble Offshore for entry into the Towing Vessel Approvability Scheme. They also provide guidance for the approval of towing vessels for a specific tow and bollard pull tests. They do not cover the towage of specific vessels or barges, guidance for which may be found in 0030/ND.

 

Guidelines for Marine Lifting Operations

This document provides guidelines on which the design and approval of marine lifting operations may be based.

 

Guidelines for the Transportation and Installation of Steel Jackets

This report sets out the guidelines on which Noble Offshore approval of the transportation and installation of steel offshore jacket structures would be based.

 

 Guidelines for Marine Transportations

These guidelines will be used by Noble Offshore for approval of specialised marine transportations, including:

a. Cargoes on ships or towed barges

b. Towage of self-floating marine and oilfield equipment, civil engineering structures and ships

but are not normally intended to apply to “standard” cargoes such as bulk liquids, bulk solids, refrigerated cargoes, vehicles or containers.

 

Guidelines for Float-over Operations

These guidelines have been developed for the float-over installation of structures onto:

  • Offshore pre-installed structures, e.g. jackets and concrete units, or
  • Offshore or inshore floating structures, e.g. TLPs, concrete units and semi-submersibles.

Guidelines for Moorings

These guidelines will be used by Noble Offshore for the approval of moorings, including:

  • Offshore catenary or taut leg moorings of mobile offshore units (MOU)
  • Offshore catenary or taut leg mooring of floating offshore installations (FOI)
  • Inshore mooring of MOUs and FOIs, e.g. for stacking
  • Temporary mooring of offshore installations in an afloat condition during construction, installation or decommissioning
  • Quayside mooring of MOUs and FOIs, e.g. during maintenance or conversion
  • Mooring of vessels during loadouts and installation operations.
