Oil Platform Haul-outs for Walruses?

Sea lions like to use marina docks as substitute haul outs where natural land or ice features aren’t available. One might think that walrus also would use man-made platforms for haul outs where available such as specially adapted offshore oil platforms in Alaska. perhaps legislation could be made to require oil corporations to attach haul-outs for walrus and polar bear on their offshore facilities. Human compensation for global warming melting of the Arctic ice pack ought to go ahead in an affordable way.

As an alternative remedy the federal government could design special electric engine powered haul out barges that would follow the ice pack recession seasonally to moor in locations where walrus and polar bear formerly had ice to rest on. Permanent moorings could be made so the barges could hook on to anchored tethers with floats that sink beneath the waves in advance of the return of seasonal ice and reappear seasonally when signaled or boat-hooked. The barges could return to the beach of the North Slope in autumn as the ice returns.
