Overview
The Umbilical Manufacturers'
Federation (UMF) decided to initiate a combined seminar/workshop on
the subject of umbilical installation due to significant
installation issues arising from time to time, and a consensus
within the industry for such a workshop.
Installing umbilical systems
subsea is comparable to installing power cables on land from a
helicopter in the dark; it is therefore understandable that there
have been issues when installing such products. With the move to
deeper waters, longer tie-back distances and subsea production
moving into increasingly hostile environments, it is likely that
installation issues will continue to be a concern for the industry.
It is with this background
that the UMF, in conjunction with the SUT, has embarked on the
combined seminar/ work-shop with the aim of obtaining a better
understanding of the issues. With this understanding, the attendees
at the event should then be able to develop a strategy as to the way
forward, with the ultimate aim of reducing the occurrences of
umbilical installation issues. The format was similar to that used
for the very successful Umbilical Blockages Seminar/Workshop; this
resulted in a joint industry project (JIP) that is well advanced in
addressing blockage avoidance, not just umbilical control and
chemical injection fluid conduits, but such conduits in the whole of
a subsea production system.
The morning session was
based on a series of high level presentations to highlight
installation issues. These provided by companies representing the
installation contractors, the umbilical manufacturers and,
additionally, the hardware designers whose equipment is frequently
provided as free issue equipment for attachment to umbilicals.
Each presentation was of
relative short duration to allow more presentations in the available
time, which provided a wider and more meaningful picture of the
issues to be addressed. The aim of the presentations was for each
presenter to provide a different aspect to avoid duplication and
maximise the detail available for consideration by the working
groups. In the afternoon session, the working groups reviewed the
presentation content and other issues identified by the workshop
participants and developed strategies for the way forward. Each
group's strategies was then presented to the other groups, followed
by an interactive discussion session with the aim of developing an
overall strategy as to how best to use the output form the event to
reduce the number of umbilical installation issues.
Speakers did not present
formal papers, but provided keynote presentations. Aberdeen was
chosen for the event, as it is where a large number of installation
contractors are based and is well served by air travel.
The current chairman of the
UMF introduced the event and provided a brief overview of the UMF
activities. Additionally, a UMF member provided an overview
presentation of the benefits of such events to the industry and how
such an approach can be useful as a means of addressing other issues
within the subsea production industry. The Umbilical Blockages
Seminar/Workshop was used as an example and the progress made to
date of the JIP that resulted form the event was highlighted.
