PAFA
Consulting Engineers is involved in the
preparation of International Standards Organisation (ISO) documents for
the design of offshore structures for oil and natural gas – the 19900
series of standards. Members
of our staff have participated in the detailed workings of panels
contributing provisions for fixed and floating steel offshore structures,
topsides and jack-ups. In
addition,
Paul Frieze
has performed detailed editing work for the
floating structures, marine operations and stationkeeping standards, as a
member of three-man editing panels.
The editing panels for stationkeeping systems and
floating structures were tasked with ensuring consistency of the documents
with the requirements of the ISO Directives (Directives
Part 2), as well as alignment with the terminology, structure and
philosophy of the rest of the ISO 19900 standards. They comprised:
Dr W R (Bob) Wolfram - Exxon Development Co,
Houston
Dr Andrea Mangiavacchi - Experia Consulting,
Houston
Dr
Paul
Frieze
- PAFA Consulting Engineers, Hampton (London).
The panel completed its work on the
stationkeeping systems standard in 2005 with publication of “ISO 19901-7
Petroleum and natural gas industries - Specific requirements for offshore
structures - Part 7: Stationkeeping
systems for floating offshore structures and mobile offshore
units.” This same panel also
worked on the floating offshore structures standard (“ISO 19904-1
Petroleum and natural gas industries - Floating
offshore structures - Part 1: Monohulls, semi-submersibles and
spars”) and completed this work in 2006.
Editing work is currently on-going on the preparation of a Minor
Amendment to ISO 19901‑7 with publication expected in late 2008.
The following links connect with the home pages
for ISO, www.iso.ch, and
technical committee number sixty seven which has a remit to consider
“materials, equipment and offshore structures for petroleum,
petrochemical and natural gas industries”, www.tc67.net.
An additional ad
hoc editorial panel was established to help finalise the standard on Marine
operations. The panel,
similar to the above but with Dr Jan Vugts of Vugts Consultancy,
The Hague
, replacing
Dr Wolfram, is currently tackling this work and is expected to complete by
the end of September 2008, shortly after the next steering committee
meeting, TC
67/SC 7.
Financial support for this editing work was provided
by the International Association of Oil & Gas Producers OGP.
