Morphology

seacock = sea + cock (semi-transparent) = sea + cock

The components 'sea' and 'cock' are identifiable, but 'cock' meaning 'valve' is a specialized nautical/technical sense that many learners may not know.

Etymology

The word seacock comes from sea and cock, where cock once meant a small 'valve', as in stopcock. So a seacock is a valve in the hull that controls water going in or out.
