Narrative:
In cruise on a random route over the north atlantic. Received level one hydraulic 3 elev off alert. Upon considering all operational and safety issues we continued on to ZZZZ. We contacted dispatch to alert ZZZZ ops that we may need a tow in. Dispatch said they would contact ops and tower. On descent we received level one alert hydraulic 3 off. On initial contact with ZZZZ ops they asked if we needed a fly by and how long a final we required and we stated no fly by and a 15 mile final. We were able to extend gear; flaps; and slats normally with the level two hydraulic 3 fail alert coming on as the landing flaps were lowered. Landed uneventfully and was able to taxi to the parking position without a tow. The captain spoke to crash fire rescue equipment and local authorities filling out the required paperwork; and later contacted dispatch.
