  • Description

    Work is almost completed here at Southampton on the installation of anti-roll stabilisers in the 61,000 gross tone Cunarder, Queen Mary. When she re-enters the trans atlantic service on April 2nd she will share with the Queen Elizabeth the distinction of being equipped with the most powerful stabilising gear afloat.

    Sir William Wallace (chairman of Brown Brothers, makers of the Denny-Brown stabilisers) said today that if the Queen Mary rolled through as much as 30 degrees - 15 degrees either side of upright - the stabilisers would reduce the roll to 1 1/2 degrees either side.

    In tank tests these stabilisers can bring a ships hull from 20 degree list to level in 2.8 seconds. The two sets fitted to the Queen Elizabeth three years ago have proved 100 per cent satisfactory in ensuring passenger comfort in heavy swells and reducing breakages.

    The Queen Mary's fine are being fitted at a cost of about GBP500,000. Installation has been a long job. It was started 14 months ago and has been proceeded with each time she called at her home port and even on voyages.

    There were difficulties to be surmounted. She has more boilers than the Queen Elizabeth and there was not sufficient suitable space in her existing machinery compartments to fit the stabiliser equipment in the orthodox manner. It was decided that the hydraulic rams working the fins should operate vertically instead of horizontally. The compartments in which the fins are housed (they retract into the ship's hull when not in use) together with the space for the operating gear are so small that all moving parts are lubricated mechanically. This makes it unnecessary for personnel to enter the compartments when the fins are operating.

    Installation of the stabilisers has involved the fitting of about 5 miles of electric cable. More than 12,000 feet of piping has also been fitted. This, together with the unusually long overhaul of the ship in general, including bull examination and scraping, extensive alteration and modernization in the kitchens (an innovation is the installation of electric grills) has cost the Cunard line well over GBP750,000. This work is expected to give the Queen Mary another 10 years of service -- 7 years above the normal "life" of a liner.

    Towards the end of this month, the Master of the 22-year-old liner, Captain George Morris, will take his ship on 24-hour trials, during which he will be asked to make his ship roll to establish how quickly she can recover from an angle of 25 degrees or more with the aid of the two sets of Denny-Brown fins.
