ROV (Remotely Operated Vehicle)

What is a ROV?

According to the “operational guidelines for the Marine Technology Society ROV ROV Committee” (1984) and “the National Research Council Committee underwater vehicles and national needs” (1996), defines the ROV (from remote operation of the vehicle) is basically an underwater robot that is controlled by the operator ROV, to stay safe, when the ROV working in dangerous environments. ROV system consists of vehicle (often called the ROV), which are connected by the umbilical cord to the control room and the operators on the surface of the water (may be on the ship, platform or barge). Also the control systems, launch systems and electrical and hydraulic power supply system. From the umbilical cord, electric energy and hydraulics, as well as orders or signals control released two addresses ROV, control room. The ROV is equipped with specific computers or sensors such as video, transponders, a compass, odometer, BATHY (d) data and other cameras based on the purposes and objectives of the survey.

History ROV

ROV history in certain first created the ROV does not know clearly. There are at least two important events, when the release of VUP (scheduled underwater Vehicle) made by Luppis-Whitehead car in Austria in 1864. ROV own name was created by Dmitry years Rebikoff 1953, making the ROV with a poodle. (Technology society Navy) Army of the United States, with high technology to develop the ROV to lift the mines in the seabed and the loss of the atomic bomb in Spain in a plane crash in 1966 incident. The next generation with the development of technology, the ROV is used to support the work of offshore oil drilling. ROV participated for the first time in this is the 225-VN and VN-150 by HydroProducts, the United States. Today, when the trend of oil and gas in deep sea exploration ever done, the ROV has become an important part of such operations.

HOW Can ROV use?

ROV is used both for the military, commercial or business and academics and research.? For example for a commercial purpose at the global oil and gas offshore is as follows:

  1. accompany divers, to ensure that divers in a room safe and ready to support
  2. Inspection or examination of the oil platforms, refineries, after a visual to use a specific tool to control the effects of corrosion, construction errors, the location of cracks, to estimate biological contamination inspection
  3. pipeline inspection, undersea pipelines continue to check for leaks, determine the approximate age of the pipe and be sure to install the pipeline in good condition.
  4. The survey, either visually or reviews by sound waves, is required before the installation of pipes, cables and other offshore.
  5. Those in favour of the drilling and construction after a visual inspection, monitoring the application of the drilling and construction services to make improvements if necessary.
  6. Move hazardous objects in the seafloor, especially around facilities construction, such as oil refineries. ROV proved capable of reducing the cost to keep these areas clean and safe.

In the field of telecommunications, which supports the work of installation of submarine cables telecommunications and surveillance, as well as maintain the wiring in accordance with the procedures to protect it from interference (trawler boat) fishermen and possibly the anchored ship. Research, among other things mentioned above, one of which investigates the changes that occur on the ocean floor after of the earthquake and tsunami.

Types of ROV based class

Based on the ROV ROV class types is composed of several types, depending on the capabilities and features of Office. There are small electric vehicles, a small ROV, mini dimension to depth of less than 300 m, usually for the purpose of inspection and monitoring, SAR, reservoirs, aqueducts and nuclear inspections are used for the inspection of coastal waters, as well as for scientific purposes. There are also relies on its ability as a vehicle of class, which uses electrical and hydraulic energy work. Most of this type to promote the use of drilling sea inside as the series Magnum ROV, owned by Oceaneering.

 

  1. Panther and Panther Plus ROV

ANTHER PLUS is a cost effective 1000m rated work tool. The control system is a standard SEAEYE product and thus fully field proven throughout the range of SEAEYE vehicles. SEAEYE’s own brand of 316 stainless steel metal shelled connectors are generally used throughout.

PANTHER PLUS incorporates the very latest carbon fibre composite material technology. Buoyancy is provided by light weight, immensely strong carbon fibre pods and some syntactic foam is also used. All vehicle electronics are housed within the carbon-fibre pods. Composite material technology provides the strength required without the attendant problems of weight, corrosion and maintenance.

The use of modern CAD techniques, coupled with the latest composite material technology, allows the PANTHER PLUS design to weigh approximately sixty percent less than ROV systems with a similar performance envelope. This in turn requires smaller, lighter and less expensive launch and deployment systems. SEAEYE SM5 brushless DC thrusters are used throughout. Seaeye brushless DC units are fully field proven with hundreds in use worldwide. Our brushless technology ensures small, efficient, powerful thruster units. PANTHER PLUS provides the user with maximum payload availability and volume.

The video system includes four simultaneous TV channels using fibre optic multiplexers and two fibre optic paths in both the tether and armoured umbilical cable. This provides for two piloting cameras and two boom cameras, or a rear facing camera and a manipulator camera; such is the flexibility of this system.

The polypropylene chassis is unencumbered with hydraulic pumps, valve chests, filters and piping. Thus PANTHER has a relatively low drag co-efficient, minimising the need for under slung tooling packages. PANTHER is able to carry sonars, two multi-function manipulators, stills camera, various video cameras, inspection/survey equipment and customised tooling. Dual scanning profiling sonars for trench applications, pipe-trackers and cable trackers may also be carried. The SEAEYE comprehensive video overlay is standard.

PANTHER’s performance and capabilities are aimed specifically at operations which would normally require much larger, heavier and more expensive vehicle systems. Easy access is provided for interfacing various equipment carried by the vehicle for offshore tasks.

Introduction

Falcon is the first ROV designed and built to meet the operational requirements of coastal and inshore operators. In developing this system the same criteria of performance, reliability and ease of operation were set but with the added challenge of creating a system that was to be portable and affordable.
Falcon & its Surface Units

The Falcon incorporates many of the features that have proved so successful in other ROVs but with a number of technical innovations never before seen in a lower cost ROV. The Falcon sets a new standard for inshore and coastal operations to 300 metres depth.
THE VEHICLE

Vehicle Specifications
Maximum Working Depth: 300 msw
Length: 1000 mm
Height: 500 mm
Width: 600 mm
Launch Weight: 50kg or 62kg with additional buoyancy module fitted
Thrust Forward: 50 kgf
Thrust Lateral: 28 kgf
Thrust Vertical: 13 kgf
Payload: 4kg or 16kg with additional buoyancy module fitted

Chassis
The chassis is made of polypropylene which is extremely rugged, maintenance free, non-corroding and self-supporting in seawater. Additional equipment may be bolted directly onto the chassis members. All fittings and the lift point are manufactured from 316 stainless steel. The core frame is manufactured using modern composite materials.

Buoyancy
Buoyancy and payload is primarily controlled by the addition or subtraction of closed cell foam blocks secured to the chassis below a quick-release, hydrodynamic polypropylene shell. (The shell also encapsulates all Falcon’s electronics housings and provides protection for cabling). Mounting points on the vehicle skids are provided for lead ballast to facilitate trimming of the vehicle’s centre of gravity and buoyancy.

Propulsion
Falcon features brushless DC thrusters, which, apart from having the greatest power density, have drive electronics with velocity feedback for precise and rapid thrust control. These thrusters are interfaced to a fast PID control system along with a solid-state rate gyro for enhanced azimuth stability, a feature that automatically prevents overshoot on a change of heading. These essential building blocks enable Falcon to provide superior control and response from their powerful ROVs, setting them apart from the competition. The innovation for Falcon was the development of a Magnetically Coupled brushless DC Thruster unit (MCT1) capable of resisting higher torque loads than competing units. Falcon is powered by 5 Magnetically Coupled Thruster units (MCT1) each capable of achieving 13 kgf thrust at 320W or a combined forward thrust (bollard pull) of 50 kgf. For an ROV weighing only 50 kilos this represents an impressive 1:1 power to weight ratio.

These thrusters run cool without being oil filled and having no moving shaft seals, are low maintenance, extremely reliable and ideal for use in sensitive areas such as fisheries and on reefs.

Thruster Configuration
4 Vectored Horizontal Thrusters
1 Vertical Thruster

Thruster vector angles can be changed by the operator to reconfigure the vehicle to best suit the particular mission requirements.

Control System
The Falcon is the first ROV to enter production with a distributed intelligence control system. This is a multi-drop network which allows up to 128 devices to be connected together on a single RS485 serial network. Each device connected to the network, be it a thruster, light, compass or a future option, contains a microprocessor and interface electronics and is called a ‘node’

These ‘nodes’ are controlled by a master processor in the Surface Unit and are fully isolated to maximise system reliability. Each node is connected to the Network’s Star Point at the ROV junction box. The Star Point is a printed circuit board that provides each node with its own fused power supply and telemetry.

This modular approach eliminates the need for a complex central electronics pod and significantly reduces the number of subsea connectors used. The result is a very flexible modern and simplified system architecture designed to improve reliability and ease of maintenance.

This modular approach eliminates the need for a complex central electronics pod and significantly reduces the number of subsea connectors used. The result is a very flexible modern and simplified system architecture designed to improve reliability and ease of maintenance.

Control System Diagnostics
A software routine automatically checks each node when the system is powered up with alarms provided on the video overlay to alert the operator. Local diagnostics are also provided for each node in the Junction Box. A test button is provided with colour coded LEDs that confirm green if the fuse is intact or red if it is blown on a particular node. A further LED indicates the presence of telemetry to the node.

The ROV Junction Box
The one atmosphere junction box contains the Network Star Point and the video line-driver. The line driver allows quick and easy ‘gain’ adjustments to be made if differing umbilical lengths are to be used. A standard bulkhead connector is used to connect each node to the Network Star Point at the junction box.

ROV Application

In its development, now using the ROV. ROV used both for the military, commercial or business and academics and research. Now, many are discovering the markets such as the ROV sea fishing, civil engineering, security, detection, and the contents of another mineral Sciences need. Now, the ROV the be multifunctional. Among others for the purpose of exploring the deep ocean documentation study, prevention, investigation, search and rescue (SAR), the drilling of quarry, digging and extension cable burial and others.

Oil and gas coast outside in the field of mining

oil and gas offshore, both inside and outside of the country, the use of the ROV is not outside. Starting from the design, installation or construction for the maintenance of underwater installations cannot be separated from the role of the ROV. Similarly, for mining, ROV services has been used by one of the company gold mine in Sumbawa, during the 1999-2000 within the framework of the installation of the line and follow-up of tailings (wastes) in the trough of the narrow sea Ay, West Nusa Tenggara.! Another application is for the purpose of the survey and repairs under water. In recognition and improvement of gas pipeline under the sea, the study and seabed position to see the piping and network security mapping activities. When the tube and out of the network only will cause major losses, especially if broken pipes and exploit, gas supply is disconnected.

The use of the ROV in the field of telecommunications

is a telecommunications cables underwater, telecommunications and monitoring support installation work, as well as maintain the wiring in accordance with the procedures to protect it from interference (drag boat) fishermen and the ability to anchor the vessel.

Research field

As mentioned the early introduction, one of which investigates the changes at the bottom of the sea after of the earthquake and tsunami. It is support in mapping the location of a treasure buried at sea in the waters of Indonesia, biodiversity, including species of rare fish bebarapa, allegedly in the waters of Indonesia and the “Deep Ocean water” (deep ocean water). Surveys and studies using ROV devices do not stop to the extent of knowledge, but rather towards the development of such industries as bottled using sea water within the raw water. In Japan, for example for bottled water as if had been developed.

Operations SAR

This technology has been applied to the research vessel Baruna Jaya IV belongs to a friend. Ship technology survey Marine to use on the master computer power: color (Dome), sonar, ecosonda multihaz, side scan sonar, and the remote operation of the vehicle (ROV). Color (cupola) able to crawl in all directions (Omni-directional) to objects at an optimum distance up to 2000 meters sonar than sea level. Multihaz system capable of tracking and mapping of the 3 (three) dimensions in detail of the seabed and oyek objects in the sea. Side Scan Sonar can trace objects on either side until the optimal distance of 400 meters to the left and right. ROV is a camera that can monitor objects at a depth of 100 meters below sea level.

How ROV system positioning under the sea?

ROV systems in the vehicle General floating above a ship, boat, or drilling rig. When you install on-board ROV system, the position of a submarine ROV refers to the point of reference in the boat. For the purposes of the survey, the vessel usually DGPS (differential global positioning system) according to the main positions. While for the position under the sea, equipped with underwater positioning equipment ROV system uses (underwater acoustic positioning) sound waves. One of these methods is the ultra short baseline (USBL), which measured the distance, depth and azimuth of the ROV to the USBL transducer mounted on the ship.

ROV position and navigation, data on a system to coordinate some is obtained from the specific navigation software, they will be sent in real-time to the ROV control room. systems ROV and use the latest technology, also supported by human resources professionals in the field. Computer support, spare parts and training for operators always does periodically. Application in particular in the field of research in Indonesia should continue to improve, and cooperation with foreign parties, he is also expected that the technology ROV can be dominated by our own people then.

    • makasih mas atas komentarnya.. hehe🙂
      tulisan ROV ini merupakan tugas waktu saya kuliah, memang masih secara umum dibahasnya.
      sebenarnya banyak sekali yg membutuhkan informasi lebih mengenai ROV.
      mungkin bisa disempurnakan oleh mas opanks.
      terima kasih mas.

  1. Good website! I truly love how it is simple on my eyes and
    the data are well written. I am wondering how I might be notified when a new post has been made.
    I’ve subscribed to your RSS which must do the trick! Have a great day!

  2. There is a re-set button for the filter that fires up
    when the filter should be replaced and another
    light that signals once the filter has to be cleaned.
    Additionally, the truth that the fan doesn’t turn off but only turns down for the lower level in the event the humidity goal is reached isn’t ideal.
    Some of which have a panel indicator that glows when
    the desiccant material becomes saturated.
