Explanation / Answer

Answer 1) The Deepwater horizon drilling rig caused the oil spill in Gulf of Mexico in 2010.

Answer 2))Several problems faced during deep water drilling makes it difficult in terms of accessibility of the materials.problems are associated with both drilling facilities band drilling operations.Some problems associated with drilling facilities are tension leg problems where the vertical moored floating structure called tension leg platform can be disturbed.

The problems associated with drilling operations are hydrate problems, loss of risers and cutting transport problem.
