Best VDR UAE Services From Linkmarine


A voyage data recorder(VDR) is an equipment that is installed onboard ships that records various data that can be utilised to reconstruct the journey details and important information during an accident investigation.

Information on a ship's position, movement, physical status, command, and control during and after an incident is saved in a safe and retrievable manner. This information is utilised to determine the cause(s) of the incident during any subsequent safety inquiry. It can also be utilised for preventative maintenance, performance efficiency monitoring, heavy weather damage analysis, accident avoidance, and training to increase safety and save operating costs.

As mentioned earlier,  VDR or voyage data recorder is an instrument that is safely mounted on a ship to continually record essential information about the vessel's performance. It has a voice recording system that has been running for at least the last 12 hours (for VDRs installed post-July 2014, the period of the integrated details recorded is 48 hours as per the MSC Resolution 333.90). In a compressed and digitised version, this recording is recovered and used for inquiry in the event of an accident.
The VDR on a ship is considerably superior to the black box on an aeroplane since it stores a wide range of data for at least 12 hours. The latest data continuously overwrites the data records from the previous 12 hours. Even when a ship is several metres deep in water, a VDR can endure severe weather, crashes, flames, and pressure extremes.

How VDR Works?

The VDR can be divided into the following units:

– The DCU (Data Collection Unit) (fitted on the bridge that pulls in data from all the integrated sources),

– A Data Recording Unit (DRU) (installed on the monkey island, which stores all data captured by the unit within the wheelhouse) and microphones for recording bridge sounds The Data Processor Unit, interfacing modules, and backup batteries are all housed in the DCU. It collects data from sensors in accordance with IMO and IEC regulations. In the event of a main ship power loss, the batteries provide power to the DCU, allowing it to record bridge audio for two hours. The data from the DCU is stored in the DRU's flash memory. After an incident, the data can be accessed using replay software for examination. The protective capsule contains the DRU components. After an incident, the capsule ensures the survival and recovery of the recorded data.

As previously stated, the data collected or brought in from all integrated sources is stored in the storage capsule, which retains information for the last 12 hours (or 48 hours) and is continuously replenished as the voyage progresses.

The bridge unit also has a record button, which when pressed (for example, during the commencement of any occurrence such as a collision or grounding), causes the recorder to begin recording a new set of data for that length of time.

The above-mentioned capsule is a tough unit that can survive the shocks and pressures that come with a shipwreck (collision, grounding, bad weather etc). It might be a float-free system, like the HRU, or it could be linked to the EPIRB for simultaneous release.

 The VDR Record the Following

  • Speed and heading (SVDR)
  • Hull opening (doors) status
  • Watertight and fire door status
  • Speed and acceleration
  • Echo sounder
  • Date and time (SVDR)
  • Communication audio (SVDR)
  • Ship’s position (SVDR)
  • Hull stresses
  • Rudder order and response
  • Radar data (SVDR)
  • Main alarms
  • Wind speed and direction
  • ECDIS data (SVDR)
  • Bridge audio (SVDR)

What is SVDR?

The SVDR is essentially a simplified VDR that only records information that is absolutely necessary and does not store as much data as the VDR does. It is, of course, more cost-effective and more often used on cargo ships. The best way to grasp the notion of SVDR is to compare the data below to that of the VDR. Information that must be recorded in an SVDR is indicated next to the category above. Only if standard interfaces are available may the last two interfaces of Radar and ECDIS be recorded.

Boiler Control System UAE - Safety & Risks

Image
What is a Boiler Control System on Ships? The Boiler Control System is intended for use in the marine sector to automate burners and combustion systems on any type of ship. On engine ships, firetube boilers are used as auxiliary boilers to deliver lesser amounts of low-pressure steam. The use of small-diameter tubes and a compact steam drum in the design of water tube boilers allow for the generation or production of steam at high temperatures and pressures. Risks Related to Boiler Control System The engine room of a ship is a complicated set of machinery and systems that is utilised to perform numerous tasks on board. The marine boiler is one such crucial piece of equipment that has been helping ships since the beginning of shipping. Initially, marine boilers were mostly used to operate a ship's propulsion system, which ran on steam (steam engine). The steam created by the boiler is now used in a wide range of engine room systems, including the heating of fuel for the main engine....

Best Waste Water Treatment on Ships From Evoqua UAE | Linkmarine

Wastewater generated onboard ships should be treated before being released overboard into the sea. Grey and black wastewater are the two types of wastewater, and their treatment can be done independently or with the same equipment to handle both grey and black wastewater. There are different modern forms of wastewater treatment equipment available, all of which are delivered as a complete unit ready to install in the engine room. Once upon, all wastewater was collected in a tank and pumped overboard if the ship is within a specified 12 miles from any coast, it will be pumped out to sea. To prevent pollution, international law now outlaws this practice, requiring wastewater to be treated to appropriate levels before being pushed over the edge. This read will help you to get more knowledge about wastewater treatment on ships.  Types of Wastewater in Ships There are mainly two types of wastewater. Grey Wastewater Black Wastewater Grey Wastewater Graywater contains wastewater from lav...

Explore the read about the hull stress monitoring system (HSMS) and the various technologies to measure it. Hull stress Monitoring System Hull stress monitoring system (HSMS) provides real-time information to the officers and masters on the ship about the motions and global stress experiences while navigating and during loading and unloading operations. The HSMS is an aid to the master. It doesn't replace his own responsibility or judgment. The HSMS includes various sensors, such as rosette gauges, long-base strain gauges, and trio-axial accelerometers to monitor hull girder deck stresses and localised stresses on side shell, cross-deck strip, bulkheads, and double bottom structure. Real-time data from these sensors are provided for urgent use and for the evaluation of the course and speed changes. Various Technologies To Measure Hull Stresses In Ships As a result, it's essential to collect a huge set of statistical data from which we may create empirical relationships that c...
