2012, that is, 30 months from project start. Equipment & technology
INS demonstrated
in submarine During recent trials with an unspecified navy, Teledyne TSS successfully demonstrated the Mk31 Inertial Navigation System (INS) in a submarine, a trial that required accurate free inertial performance when the submarine was submerged. Brian Huntsman, vice-president/general manager at
the company, said of the successful completion of the tests: “We are delighted that our latest product,
the Mk31 inertial reference system has performed so well in an extremely demanding submerged operation.” The Mk31 (2 arc minute) INS was designed to the requirement
meet for platform attitude and
heading measurement to enable compensatory data to be provided to other ships systems. It incorporates
three single-axis ring laser elements and three highly accurate accelerometers.
Aircraft carriers Huge crane
arrives at Rosyth A crane ordered by Babcock in the UK for final assembly of the UK Royal Navy’s aircraſt carriers has arrived at Rosyth dockyard from Shanghai Zhenhua Port Machin- ery Co Ltd (ZPMC) in China where it was manufactured. Te partially erected crane (with the girder and
upper sections of the legs assembled) was shipped to the UK mounted on the deck of a specialist transport vessel from the Chinese crane manufacturer’s fleet, along with all components and erection equipment including temporary erection towers, which will be used in Rosyth to complete the crane assembly. Te crane will now be fully erected to its full height
on the ship deck over a six-week period, before being transferred from ship to shore directly onto the crane rails. These were installed last year (completed in February 2010), involving a total of 380 piles through

> Marine Gears and Slide Bearings from RENK are available in a variety of designs for both commercial and naval applications.
With its highly sophisticated gear box design RENK combines propulsors such as gas turbines, diesel engines and electric motors to most effective and cost sensitive propulsion concepts for OPVs, Frigates and Air Craft Carriers. Those gear box systems operate at extremely low noise levels and are extraordinarily reliable. RENK thrust and shaft line bearings stand out for their compact design and low loss of energy, they are safe against fl ooding and shock-proof. They are also faile-safe and have proved successful in sustained operation, even in the toughest operating conditions.
Innovative Power Transmission
From minesweepers to high-speed patrol boats and submarines up to the largest frigates: RENK marine gears and bearings will give you superiority and security at sea.
