105Design for intended use and location#
(1)An operator must ensure that the structural components of an installation and any of its ancillary structures, including skids and modules, are designed for their intended use and location, taking into account
(a)the nature of the works and activities to be undertaken on and around the installation and the hazards associated with those works and activities;
(b)material properties and dimensions of the installation that may vary over time;
(c)failure modes; and
(d)applicable safety factors.
(2)The design of the structural components of an installation and any of its ancillary structures, including skids and modules, must be based on any analyses, model tests, numerical modelling and site investigations that are necessary to determine the behaviour of the installation and of the soils that support it or its mooring systems under all foreseeable operating, construction, transportation and installation conditions — including those involving geohazards — and under all foreseeable loads during the design service life of the installation.
(3)The structural components of an installation and any of its ancillary structures, including skids and modules, must be designed to
(a)withstand extreme loads that may occur during their construction and anticipated use;
(b)perform as intended during their operation under all anticipated normal loads;
(c)not fail under repeated loads;
(d)prevent damage that is disproportionate to the cause;
(e)prevent localized damage from leading to progressive or complete loss of integrity of the structure;
(f)maintain structural integrity for the time necessary to safely evacuate all persons from the installation in the event of major damage caused by foreseeable hazards;
(g)in the case of a floating platform,
(i)have sufficient stability and buoyancy reserve in the case of damage to ensure that credible scenarios of unintended flooding, if realized, do not result in the loss of the structure, and
(ii)incorporate sufficient redundancy in station-keeping systems to ensure that the structure can withstand the loss of a station-keeping component; and
(h)in the case of a self-elevating mobile offshore platform, withstand all loads to which the platform may be subjected in each mode of operation, including in the elevated position and during its removal.
(4)For the purposes of paragraphs (3)(d) to (f) and (h), the design must take into account all credible accidental load scenarios, including collisions between the installation and a vessel or aircraft.
