Rolls-Royce plc, has further expanded its capabilities with the acquisition of German company INTERING GmbH for an undisclosed sum. Rolls-Royce is now the only company able to offer tank stabilizers, through he INTERING purchase, and fin stabilizers, separately or as a combined package. Saul Lanyado, president - Marine for Rolls-Royce, said: "This acquisition makes a good strategic fit with our existing capability, allowing us to become a market leader in ship stabilizer equipment, providing a unique, tailored service to the commercial and naval marine markets." Hamburg-based INTERING was formed in 1969 and employs 30 people. Its products are in service with more than 600 ships and its sales last year were $4.1 million. As well as tank stabilizers, its portfolio includes: Anti-heeling stabilizers, designed to work while ships are stationary, securing horizontal ramps for fast loading and discharging; the INTERING Stability Test System, a stability measuring system improving both safety and payload, which won the Seatrade Award for Innovation in 1994; and the INTERING Parametric Roll Preventer, launched last year for large container and cruise vessels, protecting cargo and passengers.
