General
A.1 Safety Philosophy and Design Principles
This Section provides principles for the design, construction and installation of fire protection for offshore
substations. Minimum requirements will be described.
Requirements for definition of fire scenarios and determination of safety criteria have to be defined in
project specific documents, e.g. safety philosophy ore similar.
For paint stores and battery rooms references to hazardous area classification and applicable codes and
standards for protective measures (especially ventilation and gas detection) will be made.
A.2 Governmental Authority
Attention is directed to the appropriate governmental Authority of the country in which the unit or installation
is to be registered, operated or installed, as there may be additional requirements depending on the
size, type and intended service of the unit or installation as well as other particulars and details.
A.3 Application
A.3.1 The requirements in this Section apply to fire safety on fixed offshore installations; they are
intended to make reference to the International Convention for the Safety of Life at Sea 2012 (SOLAS),
as amended and to the MODU Code for the Construction and Equipment of Mobile Offshore Drilling
Units, 2009 or other applicable guidelines.
A.3.2 The term “Approved” relates to a material or construction, for which GL or other recognized
authority has issued an Approval Certificate. A Type Approval Certificate can be issued on the basis of a
successful standard fire test, which has been carried out by an independent and recognized fire testing
institute.
A.4 Fire safety objectives
The fire safety objectives of this chapter are to:
• prevent the occurrence of fire and explosion;
• reduce the risk to personnel caused by fire;
• reduce the risk of damage caused by fire to the unit, its equipment and the environment;
• contain, control and suppress fire and explosion in the compartment of origin; and
• provide adequate and readily accessible means of escape for personnel.
A.5 Functional requirements
In order to achieve the fire safety objectives, the following functional requirements are embodied in the
regulations of this chapter as appropriate:
1. division of the unit into main vertical and horizontal zones by thermal and structural boundaries;
