TECHNICALPRODUCTSLR: Tool To Assess Vessel Fatigue in Icy Waters An example of steel fatigue failure after testing at low temperature Lloyd's Register (LR) gives shipowners and operators a new tool to help assess designs and reduce the risk of fatigue damage in the hull structures of their ice-strengthened vessels. The development of new procedures under the notation, ShipRight FDA ICE, comes as changes in the exploitation of natural resources, the climate, world trade and marine in- frastructure are increasing marine activity in cold-climate areas. The ShipRight FDA ICE assessment procedure exam- ines ship-ice interaction loads, ice-loadimpact frequency, ice-load distribution, structural responses and the fatigue be- haviour of hull structures in cold temper- atures including associated fatigue responses. The fatigue-response assess- ment is determined for different winter conditions and ice thicknesses on typicalroutes for winter trade.Intellian Launches v240C To expand its VSAT communica- tions antenna range,Intellian Technolo- gies has launchedv240C, which is de-signed to provide uninterruptedbroadband connec-tivity compatibility with C-band. The product, intended for use on commercialand deep sea vessels, is available in two models: Circular-only polarized, or Cir- cular and Linear polarized. The latter model was developed to eliminate the need for manual changes by automati-cally switching between linear and circu- lar polarization.www.intelliantech.com Alarm PanelThrane & Thrane have developed the SAILOR 3771Alarm Panel Fleet- Broadband ? thefirst system to take advantage of non- SOLAS voice distress calling via Fleet- Broadband. Once a distress button is activated, the system is programmed to interrupt any non-urgent calls to give pri- ority to the emergency. These distress calls will be connected to operators atMaritime Rescue Coordination Centers(MRCCs), which exist in each Inmarsat- 4 satellite region. www.thrane.com GSAT Track Global Satellite USA launched theGSAT Track - a tracking solution de- signed to provide GPS tracking for both GSM and satellite applications using onesingle application, without any additional hardware or software required. GSAT Track offers online maps that display the exact location of assets - including posi- tion, speed, altitude and heading -through road maps and satellite imagery. Assets and their discrete tracking devices may be configured, grouped and reported remotely under a unified web interface. The product is compatible with all stan-dard web browsers and has been de- signed to be integrated with Falcom, Inmarsat M2M, Solara, Quake Global and Nal Research.www.globalsatellite.us Smith Berger Marine, Inc.builds a full range of Shark Jaws for AnchorHandling Tug Supply vessels.

In close communication with the manufacturer, the Hydrex engineering department designed a special cofferdam that would fit the specific needs of these operations. This was complemented with a special procedure set up by the Hydrex technical department that would make sure that all safety and quality demands could be met during the replacement. After the proposed cofferdam had been approved and constructed, the boss head bolts on the first of the ro/ro ves- sels were successfully replaced underwater by a Hydrex diver/technician team dur- ing the ship?s stop at Port of Koper, Slovenia.
