Foretract received a call on a Thursday that the VLCC Milkyway had snapped a cylinder head stud on her main engine which was a large slow speed two stroke.
She was on her way from India to Al Fujayrah in UAE to load cargo. Despite the best efforts of the ships staff they had been unable to remove the stud while on route. Foretract personnel arrived in Al Fujayrah shortly after the ship arrived at the anchorage 4 miles offshore.

Equipment and personnel travelled out to the ship by supply boat and immediately started work. Foretract Engineering’s portable equipment was set up over the broken piece of stud, still remaining in the engine entablature. (Size M72). A 1½” square was then machined in it's centre to enable it to be driven out using a purpose made driver. The stud was replaced and cylinder head refitted. Foretract Engineering staff left the vessel again by supply boat less than 24 hrs after arrival on board.
