Two recent NEL developments, the Hydropin anchor and a down-the-pile air-operated pumpe, are briefly described in the context of pumping seabed solids from considerable depths. Hydropin is a self-burying anchor, which fluidizes the underlying seabed and pumps the resulting slurry above itself. When deep-buried it has very high resistance to pull-out. As it is like a solids-handling pump intake, various pumping methods for this anchor are discussed. In pile-driving operations the continuous removal of spoil from the bore can make driving easier. Fluidizing, jet-cutting and pumping methods for this duty are considered.
