Description: RULES AND REGULATIONS FOR THE CLASSIFICATION OF A FLOATING OFFSHORE INSTALLATION AT A FIXED LOCATION PART 1
Lloyd's Register (hereinafter referred to as LR), which is recognized under the laws of the United Kingdom as a Corporation whose business is conducted for the benefit of the community, was founded in 1760. It was established for the purpose of obtaining for the use of Merchants, Shipowners and Underwriters a faithful and accurate Classification of Merchant Shipping and whilst it still continues to fulfil that purpose, it now also:
(a) approves design, surveys and reports on: hovercraft; ships which embody features of a novel kind; non-mercantile shipping; yachts; amphibious and land and sea and sea bed installations, structures, plant, etc.; machinery, apparatus, materials, compo¬nents, equipment, production methods and processes of all kinds; for the purpose of testing their compliance with plans, specifications, Rules, Codes of Practice, etc., or their fitness for particular requirements;
(b) acts with delegated authority on behalf of numerous governments in respect of Statutory Requirements;
(c) provides other technical inspection and advisory services relating to ships and the maritime industry generally and also in respect of land and sea-based undertakings.

Introduction

The Rules are published as a complete set, individual Parts are, however, available on request. A comprehensive List of Contents is placed at the beginning of each Part.
Numbering and Cross-References
A decimal notation system has been adopted throughout. Five sets of digits cover the divisions, i.e. Part, Chapter, Section, sub¬Section and paragraph. The textual cross-referencing within the text is as follows, although the right hand digits may be added or omitted depending on the degree of precision required:
(a) In same Chapter, e.g. see 2.1.3 (i.e. down to paragraph).
(b) In same Part but different Chapter, e.g. see Ch 3,2.1 (i.e. down to sub-Section).
(c) In another Part, e.g. see Pt 2, Ch 1,3 (i.e. down to Section).
The cross-referencing for Figures and Tables is as follows:
(a) In same Chapter, e.g. as shown in Fig 2.3.5 (i.e. Chapter, Section and Figure Number).
(b) In same Part but different Chapter, e.g. as shown in Fig. 2.3.5 in Chapter 2.
(c) In another Part, e.g. seeTable 2.7.1 in Pt 3, Ch 2.
Rules updating
The Rules are generally published regularly and changed through a system of Notices. Subscribers are forwarded copies of such Notices when the Rules change.
Current changes to Rules that appeared in Notices are shown with a black rule alongside the amended paragraph on the left hand side. A solid black rule indicates amendments and a dotted black rule indicates corrigenda. A dot-dash line indicates changes necessitated by International Conventions, Code of Practice or IACS Unified Requirements.
Rules programs
LR has developed calculation software for floating offshore installations. For details of this software please contact LR.
Direct calculations
The Rules require direct calculations to be submitted for specific parts of the unit structure or arrangements and these will be assessed in relation to LR's own direct calculation procedures. They may also be required for units of unusual form, proportion or speed, or for special restricted service and as sup¬porting documentation for arrangements or scantlings alterna¬tive to those required by the Rules.
Lloyd's Register is an exempt charity under the UK Charities Act 1993.
Lloyd's Register, its affiliates and subsidiaries and their respective officers, employees or agents are, individually and collectively, referred to in this clause as the "Lloyd's Register Group". The Lloyd's Register Group assumes no responsibility and shall not be liable to any person for any loss, dam¬age or expense caused by reliance on the information or advice in this document or howsoever provided, unless that person has signed a contract with the relevant Lloyd's Register Group entity for the provision of this information or advice and in that case any responsibility or liability is exclusive¬ly on the terms and conditions set out in that contract.

CLASSIFICATION OF FLOATING OFFSHORE INSTALLATIONS AT A FIXED LOCATION

UPDATE NOTES
1. The April 2008 version of these Rules and Regulations incorporates those changes contained in the Notices to the May 1999 version.
2. Changes approved by the Board and the General Committee in 2007/2008.
3. Editorial amendments have also been incorporated.
4. The April 2008 version of these Rules and Regulations supersedes the May 1999 version.
CLASSIFICATION
The following explanatory note is offered to assist those concerned in the application of these Rules and Regulations.
Explanatory Note
Unit classification may be regarded as the development and worldwide implementation of published Rules and Regulations which, in conjunction with proper care and conduct on the part of the Owner and operator, will provide for:
1. the structural strength of (and where necessary the watertight integrity of) all essential parts of the hull and its appendages;
2. the safety and reliability of the propulsion and steering systems; and
3. the effectiveness of those other features and auxiliary systems which have been built into the unit in order to establish and maintain basic conditions on board whereby appropriate cargoes and personnel can be safely carried whilst the unit is at sea, at anchor, or moored in harbour.
Lloyd's Register (LR) maintains these provisions by way of the periodical visits by its Surveyors to the unit as defined in the Regulations in order to ascertain that the vessel currently complies with those Rules and Regulations. Should significant defects become apparent or damages be sustained between the relevant visits by the Surveyors, the Owner and operator are required to inform LR without delay. Similarly any modification which would affect Class must receive prior approval by LR.
A unit is said to be in Class when the Rules and Regulations which pertain to it have, in the opinion of LR, been complied with, or when special dispensation from compliance has been granted by LR.
It should be appreciated that, in general, classification Rules and Regulations do not cover such matters as the unit's floatational stability, life-saving appliances, pollution prevention arrangements, and structural fire protection, detection and extinction arrangements where these are covered by the International Convention for the Safety of Life at Sea, 1974, its Protocol of 1978, and the amendments thereto, nor do they protect personnel on board from dangers connected with their own actions or movement around the unit. This is because the handling of these aspects is the prerogative of the National Authority with which the unit is registered. A great many of these authorities, however, delegate such responsibilities to the Classification Societies who then undertake them in accordance with agreed procedures.
