Traduction de «Wave height » (Anglais → Français) :

Physical conditions of oceans (currents, salinity, wave heights, etc.).

[Text] Question No. 14 Mr. John Cummins: With regard to the used hovercraft, the Liv Viking, which was recently acquired by the Canadian Coast Guard base at Vancouver International Airport to provide search and rescue service: (a) what was the original purchase price of the Liv Viking when originally constructed; (b) what was the purchase price of the Liv Viking paid by the Government of Canada; (c) what was the cost of the refit; (d) what were the design costs; (e) what were the costs of survey engineering and related feasibility work; (f) what were the travel and associated expenses of the Coast Guard, Public Works and other government agencies associated with the selection, design, purchase and refit of the Liv Viking; (g) what wer ...[+++]e the total administrative charges levied against the project; (h) what was the cost to put the Liv Viking into service; (i) when was the Liv Viking originally constructed; (j) when did it go into service in Europe; (k) what was the nature of the service in Europe; (l) when was it withdrawn from service in Europe; (m) why was it withdrawn from service in Europe; (n) how many hours of service did it have in Europe; (o) what happened to the hovercraft when it was taken out of service in Europe; (p) what are the maximum wind conditions (in knots) in the Coast Guard's Search and Rescue (SAR) Area 303 (where the Liv Viking will be expected to operate) in (i) spring, (ii) summer, (iii) fall, and (iv) winter and is the craft certified to operate in such conditions; (q) what is the wave height (percentage of time) in SAR Area 303 for the following wave height conditions – 0-1 metre, 1-2 meters, 2-3 metres and 3 or more metres – in (i) spring, (ii) summer, (iii) fall, and (iv) winter and has the craft been accredited to operate in such conditions; (r) do the operational performance requirements ensure that the craft has the ability to (i) undertake search and rescue operations in wave heights of 3 metres and winds of 40 knots, ( ...

It has been found that it is not practical to set absolute limits for significant wave heights, peak periods and zero crossing periods of the model wave spectra. An acceptable margin has therefore been introduced.

Sheltered waters - Designed for voyages on sheltered coastal waters, small bays, small lakes, rivers and canals when conditions up to, and including, wind force 4 and significant wave heights up to, and including, 0,3 m may be experienced, with occasional waves of 0,5 m maximum height, for example from passing vessels".

regular services in an area where the probability of wave height exceeding 2 metres is less than 10 % and — either the entire voyage is less than 30 miles from departure — or a public service obligation exists for outlying communities.

More important, only a very small number of these can operate offshore of Atlantic Canada and in the Beaufort Sea due to the unique challenges these operating environments provide, such as ice, harsh weather conditions and wave heights.
