Description / Abstract:
This part of ISO 19905 specifies requirements and guidance for
the site]specific assessment of independent leg jack]up units for
use in the petroleum and natural gas industries. It addresses:
a) manned non]evacuated, manned evacuated and unmanned
jack]ups;
b) the installed phase at a specific site. To ensure acceptable
reliability, the provisions of this part of ISO 19905 form an
integrated approach, which is used in its entirety for the
site]specific assessment of a jack]up.
This part of ISO 19905 does not apply specifically to mobile
offshore drilling units operating in regions subject to sea ice and
icebergs. When assessing a jack]up operating in such areas, it is
intended that the assessor supplement the provisions of this part
of ISO 19905 with the provisions relating to ice actions and
procedures for ice management contained in ISO 19906.
This part of ISO 19905 does not address design, transportation
to and from site, or installation and removal from site. However,
it is advisable that the assumptions used in the assessment be
checked against the as]installed configuration.
To ensure that the design of the jack]up is sound and the
structure is adequately maintained, this part of ISO 19905 is
applicable only to independent leg jack]ups that either:
hold a valid classification society certification from a
recognized classification society (RCS) throughout the duration of
the operation at the specific site subject to assessment;
or
have been verified by an independent competent body to be
structurally fit for purpose for elevated situations and are
subject to periodic inspection, both to the standards of an
RCS.
NOTE 1 An RCS is an International Association of Classification
Societies (IACS) member body, meeting the RCS definition given in
3.52.
Jack]ups that do not comply with this requirement are assessed
according to the provisions of ISO 19902, supplemented by
methodologies from this part of ISO 19905, where applicable.
NOTE 2 Future revisions of this part of ISO 19905 can be
expanded to cover mat]supported jack]ups. N
OTE 3 Well conductors are a safety]critical element for jack]up
operations. However, the integrity of well conductors is not part
of the site]specific assessment process for jack]ups and is,
therefore, not addressed in this part of ISO 19905. Annex A
provides references to other publications addressing this
topic.
NOTE 4 RCS rules and the IMO MODU code provide guidance for the
design of jack]ups
