General description

 

4

What data/products do you currently use ?

  • Winds, waves and currents data (Waveclimate.com (also coastal locations) )
  • Pressure at sea level (altimeter)
  • Rainfall: TRMM, Tropical Rainfall Measuring Mission
  • Air temperature above the sea
  • Monitoring of temperature/pressure and solar radiation conditions

5

When do you use this kind of dataset?

These data and products are mainly used during design phases.

Some data are used in specific cases, for example:

• Air temperature above the sea: for design to evaluate the efficiency of pumps of FPSO (Floating production storage and offloading)

• Solar radiation: to evaluate the efficiency of platforms in the Middle East.

• Tair, SST, rainfall, cloud cover/lightning, wind, current, wave are needed il all phases of the project and mainly during development to evaluate the efficiency of the structure. Wind and wave data are useful to evaluate buoyancy perturbation

What are your actual limitations and do you have a work around? 

n/a

7

Needs and expectations on EO data

Air temperature and wind fields above land could be good to have thanks to EO data.

Topographic classification / Offshore classification

All topographic classifications

Profiles are always needed, as well as the deep sea currents.

Activity impacted/concerned

Money saving

12

Urgency

(How quickly does the user need the solution)

The capability of having wind fields above the land and Tair above water would also be useful.

 

Information requirements

 

13

Update frequency

SAR: 2 images per day would be good

Metocean data : OK for the time being

14

Temporal resolution

 

15

Spatial resolution

For offshore a resolution of 20 – 25 km is OK. The main difficulties are located on coastal area.

16

Data quality

Ok for the time being

17

Data Coverage and extent

Perhaps more easy access to some area outside the limitation [52°N-52° S].

18

Example formats

Matlab or Fortran would be fine. But most important, the tools to read the products are needed.

19

Timeliness

Ok for the time being

20

Existing standards
