0027-nd rev 11.2 8-jul-16 guidelines for marine lifting and lowering operations
GUIDELINES FOR MARINE LIFTING & LOWERING OPERATIONS 0027/ND Rev 11 Page 7 of 84 2 INTRODUCTION 2.1
This document provides guidelines on which the design and approval of marine lifting operations may
be based.
2.2
It covers lifting operations by floating crane vessels, including crane barges, crane ships, semi-
submersible crane vessels, jack-up crane vessels, winches or derricks. It refers to lifting operations
inshore and offshore and to installation of subsea equipment excluding pipelines and flowlines which
are covered in 0029/ND “Guidelines for Submarine Pipeline Installation”, Ref. [4]. Reference is also
made to lifting operations by land-based cranes for the purpose of load-out or load-in onto or from a
barge or other transportation vessel.
2.3
The guidelines and calculation methods set out in this report represent the views of GL Noble Denton
and are considered to be sound and in accordance with offshore industry practice. Operators should
also consider national and local regulations, which may be more stringent.
2.4
The Report includes guidelines for the safety factors to be applied, comments on safe rigging practice
and the information and documentation to be produced by others in order to obtain GL Noble Denton
approval.
2.5
Revision 2 superseded and replaced the previous version, Revision 1, dated 11
th
August 1993.
Principal changes in Revision 2 included:
Reference to the ISO Draft Standard on weight control
Reserves specified on weights as calculated or measured according to the ISO/DIS
Limitations of GL Noble Denton Approval clarified
Changes to the required clearances on pipelines and other subsea assets
Addition to a section on heave-compensated lifts
Addition of a section on lifts using Dynamic Positioning.
2.6
Revision 3 superseded and replaced Revision 2, and includes additional clarification on safety factors
for shackles, and testing and certification requirements.
2.7
Revision 4 superseded and replaced Revision 3, and includes:
Changes to referenced documents (Sections 2.3 and References)
Some changes to definitions (Section 3)
Changes to Dynamic Amplification Factors, to eliminate discontinuities (Section 5.7)
Elimination of an anomaly in the definition of Hook Load (Section 5.3)
Inclusion of consideration of fibre slings (Sections 5.10, 5.15 and 12)
Elimination of an anomaly in the treatment of spreader bars and frames (Sections 5.16 and 7.5)
Modification of the flow chart (old Section 5.16)
Changes to the derivation of bumper and guide design forces (Section 10.3).
2.8
Revision 5 superseded and replaced Revision 4, and corrected typographical errors in Table 5-1.
2.9
Revision 6 superseded and replaces Revision 5, and made the following principal revisions:
The Guideline refers as appropriate to other standards, including
ISO International Standard ISO 2408 - Steel wire ropes for General Purposes – Characteristics,
Ref. [9]
ISO International Standard ISO 7531 - Wire Rope slings for General Purposes - Characteristics
and Specifications, Ref. [10]
Definitions in Section 3 were generally revised and expanded.
Section 4.1.2 added for the Certificate of Approval
