"In October 1913, Imperator returned to the Vulkan shipyard to facilitate drastic work to improve handling and stability, as it had been discovered that his center of gravity was too high (see metacentric height). To correct the problem, the marble bathroom suites in first class were removed and heavy furniture was replaced with lightweight wicker cane. The ship's funnels were reduced in height by 9.8 ft (3 m). Finally, 2,000 tons of cement was poured into the ship's double bottom as ballast. This work cost £200,000, which had to be borne by the shipyard as part of their five-year warranty to the shipowners."
