Apologies: Raymond Nerzic (RN), and Marc Prevosto (MP)
MO gave a review of the situation.
Corsica Ferries have been asked to keep a log of conditions, RN is expecting diskette from CF soon.
Problems with getting permission from Meteo France to use forecasts (hence Corsica Ferries may not have kept forecasts up to now). In principle permission expressed by Phillipe Dandin, but message has not been passed down to necessary level.
In summer 1999 CF have made more trips to Calvi than Bastia (response to technical and/or operational requirements rather than metocean conditions).
Potential alternative source of forecasts: Greece (Athens?)
IR presented questions on how satellite data should be processed and what statistical analyses were required to allow appropriate fatigue/crack propagation calculations. Subsequent discussion did not arrive at definite conclusion. IR to write a note on his understanding and intentions for processing, which will also form contribution to annual report. Discussed possibility of using Dockwise VAC package.
DC presented overview of sampling of Rotterdam-Boston route by TOPEX altimeter. Intention is to provide data in approx. ten regions across N. Atlantic. Aim is that UL will use data to reconstruct time series structure for studying crack propagation.
PB presented progress on comparing IMDSS, GWS, Cliosat climatologies for Dover-Gibraltar using VAC (Voyage Acceleration Climate) programme developed for SAFETRANS. Some significant differences between climatologies. These differences may be due to a number of reasons, possibly related to reliability of GWS data, small time scale (3 years) of IMDSS data base. CL noted that expert analysis (IFR/OPT/SOS?) is required on these differences.
Expect to finish analysis by November and complete work package by December.
DC will provide PB with SOS data for Dover-Gib for further comparisons. Further comparisons will consider three other routes, Soarzig Loarzel working at DW to prepare Cliosat data.
DW also requested guidance on best technique to calculate extreme values.
Galaxy II voyage: Aug-Oct 1998. Singapore-Halifax (Canada)
On this voyage DW were shipping motion sensitive large load (200m platform legs). There was an operational requirement that ship did not encounter > 4m significant wave height. Ship was equipped with motion sensors and bow mounted radar, and meteorologists were carried on board. Vessel encountered unpredicted severe conditions off S. Africa (9.5m SWH measured by bow radar)
SOS have provided altimeter/scatt and SAR data for time of voyage. 7 days identified with useful co-located data. Further analysis required to investigate differences between bow-radar and altimeter measurements. Attempting to locate wave model maps for this period.
First conclusion is that in current arrangement satellite data are useful for post event analysis but are not available in sufficient quantity for reliable operational use.
Dockwise Express 20 - "Sea State Alarm" Trial - Cable laying California-Guam May-July 1999.
Fast delivery satellite data overlaid on forecast maps were sent to ship, also email warnings of severe conditions. Mapped information was useful and enabled operations to prepare for heavy weather.
CL/PB have recommended changes to the way data are processed and made available to user. Intend to develop modified system for "COMKIAS".
MO and DC presented some systems which use satellite data to monitor surface currents. MO to provide review. DC will investigate present status on availability and usefulness of sea surface temperature and ocean colour data (as markers of currents).
GL provided EC financial statements and summary of COMKISS finances.
OPTIMER must provide cost statement for 12 months if they wish to receive money! DW costs had had an incorrect exchange rate (ECU to Belgian Francs) applied.
DC provided overview. Noted that analysis work packages should be completed, with the generation of activity report, by end March 2000. Note that where documents are provided to project, status should be clearly indicated (e.g. not for dissemination outside COMKISS team).
UL will process data during September, allowing BV to carry out calculations during Oct-Dec.
(DW are prepared to make VAC package available. Output from GWS/IMDSS could be compared against UL calculations. PB is planning to visit Lund in late October)
Aim is to design to ensure a safe 15 day margin from detection of crack to arrival at port. UL will use (unevenly sampled) satellite data to try to establish structure of time series for conditions on Rotterdam-Boston route. Could compare against Monte-Carlo simulations and output of VAC programme (see above re visit of PB to Lund in October). IR to write definition of approach for annual report.
BV trials in June 1998 do not have co-located satellite data on same day. However, BV carried out further trials from April-July this year, and stress measurements are available. DC will investigate availability of satellite data during these trials. If suitable data are available GP will use these data to calibrate model. Comparisons against tank test results may be possible. Because of subsequent dependency of WP4200 this package should be completed by (at least) end December.
As reported in the data workshop, data are being gathered during the Corsica Ferries summer operating season. A meeting will be held with IFREMER/OPTIMER/SOS and Corsica Ferries at the end of their season (early October?) to review the season and identify important events and define the next stages of this work package.
Requires specification of HSC, and calibrated model from BV. Before work can start on this WP, review progress on WP3300 early November. If OK IFR to produce required inputs (directional spectra) based on satellite data input.
As reported in the data workshop, climatology comparisons well under way. Need to prepare Cliosat data for other routes. then carry out three way comparison for three remaining routes. Also to run VAC programme with SOS Dover-Gib data (provided by SOS by beginning October). UL to provide guidance on calculation of extreme values.
DW will provide single report on Sea State Alarm trial and Galaxy II voyage, after further analysis of ship radar and altimeter data for Galaxy II. Should complete by end November.
See data workshop for details. MO to provide review of present systems, and potential for operational use. DC to provide analysis of global availability and applicability of satellite sea surface temperature and ocean colour data.
No further progress possible until results from WP3000, 4000, 5000 available. Note that it is necessary to provide some objective analysis of cost benefit of using satellite data
First draft of sections should be provided 7th September.
Editor of chapters (See below) to chase up contributors, compile and pass round participants in their Work Package.
Final version of chapters to DC by 21st September. DC to produce combined final report by 28/09/99

f) Oct 2000: User workshop ALL to attend plus industry representatives
COMKISS participants are encouraged to consider submitting COMKISS abstracts to ISOPE.
User Workshop: CEO officer (Bussinaro) had indicated this was important part of programme. Suggestion is to hold it close to time and location of Joint Industry Programme week (October 2000) to maximise potential attendance of users and providers.
CL is intending to submit COMKIAS proposal for Framework V call, deadline 15/01/2000. COMKIAS will propose to develop and test a pre-operational on board advisory system for offshore operations which will combine on board measurements with merged forecast/satellite data. Aims to improve operational safety/efficiency and act as step towards risk based design.
ALL are encouraged to consider and contact potential users in various sectors: Fast ferries/ military/Dredging/offshore installations/Heavy Load Transports/Survey. Should discuss with user a wish list of aims for COMKIAS system, and definition of what it should contain for their operation (instrumentation, analyses)
