Recently, Transas Marine has completed the installation and commissioning of the Transas T-Bridge integrated bridge system for three ice class ships.
It is reported that the three ships were built by Keppel Singmarine, a Singapore shipyard owned by Keppel, and official naming ceremony was held on September 10.
Transas' integrated bridge system for these three vessels includes a complete navigation system, internal and external communication systems and CCTV systems, featuring navigation safety, ease of operation and flexible configuration.
The three vessels are the ice-class supply vessel "Bumi Uray", the ice-class supply vessel "Bumi Pokachi" and the ice-class multi-purpose rescue vessel "Bumi Naryan-Mar". The owner is the international seashore based in Malaysia. Bumi Armada Berhad, an oilfield service provider, is also one of Asia's top OSV owners and operators, and will ship in the Caspian Sea after delivery.
Globe valve, also known as cut-off valve, is a mandatory sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from under the valve disc, the resistance that the operating force needs to overcome is the friction force between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve should be large, otherwise the failure of the top of the valve stem will occur. According to the connection method, it is divided into three types: flange connection, thread connection and welding connection. After the appearance of the self-sealing valve, the medium flow direction of the globe valve is changed from the top of the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be adjusted accordingly. decrease. At the same time, under the action of the medium, this form of valve is also tighter. my country's valve "Three Chemicals" once stipulated that the flow direction of the globe valve should be from top to bottom. When the globe valve is opened, the opening height of the valve disc is 25% to 30% of the nominal diameter. The flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the globe valve should be determined by the stroke of the valve disc.
