The
software has been designed to operate in an intuitive and
interactive way, making full use of the Windows Graphical
User Interface (GUI). Run-time operations are completely
menu driven using mouse and/or keyboard input, and
information is presented on full colour graphic displays.
Flexible input data files are used to define the geometry
and response characteristics of the vessel, details of the
mooring system and the geometry of any field objects with
clearance monitoring points. All data files may be created
and modified by the user. Simple moorings need a minimum of
data.
The
Mooring system may be easily modified with SEAMOOR 2000. The
vessel may be moved to any desired position within the
pattern, or the entire system may be relocated and
re-orientated in a single operation. Anchors may be
repositioned and line pay-outs adjusted so as to achieve any
required mooring arrangement. A unique feature enables
calibration of the system to match known line tensions and
pay-outs at known vessel positions
SEAMOOR 2000 is a moorings analysis and advisory program
which has been specifically developed to meet the needs of
those involved in the operational management of spread
moorings,. Such as;
-
offshore drilling rigs
-
construction barges
-
accommodation vessels
The
program may be used on-board and in the office, where it
will enable all aspects of mooring and station keeping
performance to be assessed rapidly and accurately. SEAMOOR
2000 includes low frequency motion prediction and line
dynamic response calculations in order to address deepwater
mooring challenges.
The
program can also be used for:
-
Response engineering
-
Operational planning
-
Bid preparation
SEAMOOR 2000 provides an easy to use capability for decision
support on-board offshore vessels, where it can undertake a
wide range of tasks:
-
Predict vessel excursions and line tensions under
existing or forecast environmental conditions.
-
Advise the line payout adjustments needed to achieve a
desired vessel position and heading.
-
Estimate actual vessel position from known line
tensions.
-
Monitor gangway movements plus vessel and line
clearances from other structures.
-
Compute line catenary profiles and pipeline clearances.
-
Determine the consequence of any single line failure.
Postprocessor output:
SEAMOOR 2000 presents key information graphically on a plan
view which shows the vessel outline at its mean position,
together with the anchors and all deployed mooring lines.
Line condition is indicated by colour (red for high tension)
and line style (dashed if failed). Field features such as
pipelines, wellhead templates and platforms can also be
displayed. Zooming in/out and panning across the plan view
is easily accomplished. Range rings or co-ordinate grids may
be overlaid on the view, and clearance distances between
particular points on the vessel and other objects can be
shown as required.
A text
panel displays a summary of numerical results for
environment load, vessel excursion and line tensions. Pop-up
dialogue boxes display other information and accept input
data. Catenary details can be called in a separate window
where line profile and pipeline clearances are shown for the
maximum and minimum tensions under the prevailing
environment.
