A new dimension in LNG vessel automation KONCSBERC is a leading supplier of complex Integrated Automation Systems (IAS) for highly advanced special vessels worldwide. Applications covered by the technology include field exploration and drilling, oil and gas processing (FPSOs and fixed installations), shuttle tankers Close co-operation with ship owners, yards and other main suppliers during vessel design and commissioning ensures an integrated solution, which makes the complete system more efficient in both economical and technical aspects. Both end user and yard will benefit from the advantage of one supplier taking complete responsibility for the integration of the system. The design criteria for KONGSBERG'S Integrated Automation System is reliability and safety, • Segregation - autonomous process areas have dedicated process controllers with • Redundancy within data communication network and process controllers • Simplicity - small range of components to facilitate modularization • Fault tolerant design, based on fail-safe principles

Integrated solution - The Full Picture By integrating the different functions into the IAS, the overall need for hardware and software functions and interfacing requirements is reduced, which leads to less demand for special software, cabling and testing. Furthermore, integrated systems offer a far greater degree of redundancy and therefore increased system availability and operation performance. Tunnel Thruster The modern Integrated Automation System is a distributed monitoring and control system covering all important functions on board, such as • Power management • Auxiliary machinery •...

CTS – Custody Transfer System Kongsberg radar based level gauging systems and Custody Transfer Systems have been in operation on gas tankers since 1989. The Custody Transfer System (CTS) is designed for LNG carriers, both with spherical and membrane type tanks. The radar based level gauging system, the temperature sensors and the pressure transmitters are all specially designed to provide continuous and reliable accuracy in the demanding environment of liqueed gas. With the unique AutroCAL® function we have provided the market with the rst fully automated calibration and verication method...

AutroCAL® - the unique calibration and verification function Gas vapour density and the mixture of gases influence the propagation speed of the radar signal and thus the accuracy of the measurements. By using the designed still pipe joint signatures for continuous measurement and calibration, combined with accurate temperature measurement, AutroCAL® continuously compensates for inaccuracies caused by the differences in the propagation speed. Thus, our AutroCAL® verification and calibration function automatically ensures that the same high accuracy is maintained over the whole measurement...
