| 28 Oct | 1245 | 9.30 | Attempted to wash down to 12 mbsf to take HS; driller noted change in drilling parameters and stopped at a depth calculated to be 9.3 mbsf; a roughneck was detailed to the rooster box, but before he got halfway he was recalled, as the wind had suddenly picked up to a strong level; (60kt) within a very short time (seconds) the ship then moved, apparently bending the string; driller was able to trip one pipe off the string and sky the remainder to make the string safe; template was brought back on deck and the drill deck made secure | ||||||
