ROV Hull Surveys

Posted Leave a commentPosted in Uncategorized

There are many safety advantages that ROVs can provide over divers. This short article will point the advantages of ROVs over human divers:

Hull ROV Surveys
  • Ship hull inspections can be dangerous for divers because a port is a very dangerous place.
  • Currents can move diver to unsafe places during Inspections.
  • Rapid deployment
  • Less permits and safety considerations pre-launch
  • 24/7 operations without restrictions.
  • No restriction depth (within manufacture limits)

Vessel Warranty Surveys

Posted Leave a commentPosted in Uncategorized

A Vessel Warranty Surveyor provides independent third-party technical review and approval to any marine vehicle or structure, It is crucial to include surveyors from the planning stages through to the physical execution. 

You will get:

  • Independent and impartial advice.
  • Review, approval, and attendance for location surveys in accordance with regulations, standards, and best practices.
  • Condition and suitability surveys for a wide range of vessels.

Boats Corrosion Surveys

Posted Leave a commentPosted in Uncategorized

Most of us has been affected by corrosion our boats.

There are different  types of corrosion affecting our boats:

In simple words, Corrosion is the irreversible damage or destruction of a material due to a chemical or electrochemical reaction with the environment.

Metal Corrosion is Caused when it reacts with another substance such as oxygen, hydrogen, an electrical current, or even dirt and bacteria. Corrosion can also happen when metals like steel are placed under too much stress causing the material to crack

On boats are mainly three types of corrosion:

Galvanic Corrosion:
It is simply an electrochemical reaction between two or more different metals. The metals must be different because one must be more chemically active (or less stable) than the others for a reaction to take place. When we talk about galvanic corrosion, we’re talking about the electrical exchange. All metals have electrical potential because all atoms have electrons, which have an electrochemical charge. (see https://www.boatus.com/)

Electrolytic Corrosion:
It is simply a process of accelerated corrosion. In this process, a metallic surface is continuously corroded by other metal it is in contact with, due to an electrolyte and the flow of an electrical current between the two metals, caused from an external source of electromotive force.

Ordinary Corrosion: 
Some times called rust, it is a chemical process which results in the formation of red or orange coating on the surface of metals, this reaction causes damage and disintegration of the metal starting from the portion of the metal exposed to the environment and spreading to the entire bulk of the metal.

ROV Operations by 1 Person

Posted Leave a commentPosted in Uncategorized

ROV allows us to do quick and safe underwater surveys, easy deployment, portable and easy to transport:

When planning dives, please consider the following elements:

  • The mission objective.
  • Degree of accuracy required.
  • Current threat level.
  • On-scene conditions.
  • The amount of time plus resources available.

In this video, we will check how a single man underwater survey is carried out.

Current and Flowmeter Surveys

Posted Leave a commentPosted in Uncategorized

24 marines team and equipment are ready to record currents and calculate water flows at your location.

By using balance impeller magnetized, producing a magnetic field when rotating which is passed through the cable user display. The unit is calibrated regularly at the factory.

By using electromechanical sensors, we can reduce the cost of flowmeter adquisition and calculations without comprimizing quality and precision.

ROV on Aquaculture Industry

Posted Leave a commentPosted in Uncategorized

Since 1961 the Fish consumption has increased, twice as high as the population, according to http://www.fao.org/.

The statistics show that aquaculture has its highest peak about 2016 with 171 million tonnes production, so, fish farming has become one of the major contributors to the world food providers, here a few benefits of aquaculture:

  • Increased production of food for human consumption.
  • Substitution of import by local production.
  • High-efficiency protein production.
  • Creation of employment, especially in rural areas.
  • Environmental Friendly.

As the fish demands increase, the need for efficient managing technics is getting higher. Robotics and remotely operated vehicles are playing a great role in this industry, here below some of the benefits using ROVs on aquaculture:

Species Monitoring:

Delta ROV allows fish farming operators to monitor conditions, growth, behavior, and health of the fish stock, with gripper and manipulators ROV can recover dead fishes, samples, etc.

Gear monitoring:

In order to monitor (Nets, Filters, buoys, anchors) and comply with regulatory requirements and monitoring harmful species (sharks, sealions) out of the farm, Delta ROV is ready to operate 24/7 on the fish farms.

With the usage of ROVs, operators can develop methods for increasing efficiency and safety on Aquaculture industry.

Why to use ROVs?

Remotely Operated Vehicles, or ROVs, are submergeable robots that are controlled from above the water. ROVs are connected to the topside via cable umbilical (tether) cable and controlled using a joystick in a similar to play a video game. A group of cables, connects the ROV to surface station, sending electrical signals back and forth between the operator and the vehicle.

Here we summarize few of the benefits of using ROV for our underwater surveys:

Reducing Human Exposure:

Human divers can only submerge to certain depths for a restricted period of time, and the skill and danger involved makes deepwater diving unrealistic.

Reaching Deeper:

ROVs allow us to investigate areas that are too deep for humans (divers) to safely reach themselves.

Diving Longer:

Remote Operated Vehicles can stay underwater much longer than a human diver, expanding the time available for exploration. The only limitation will be the power source (battery or power supply).

Although ROVs were not as successful initially, the technology has come a long way, and now Underwater Vehicles are regularly used offshore for petroleum developments and drilling, fishfarming, military and oceanogrphy investigations.

Thermo Inspection with Drones

Posted Leave a commentPosted in Uncategorized

Thermo cameras allow us to see infrared and thermal energy that is always around us.

Visible Light It is like the tip of the Iceberg, with our eye we just see around 2.5% of the available out there.

We don’t perceive infrared (thermal energy) as they are no visible for our eye, as the spectrum  that we eye can detect is very limited.

Infrared has about 30% of the available light spectrum, see image below:

In simple words, the main differences between visible Light and Thermo Energy:

  • Our eye can see what is reflected from the surface.
  • Thermo energy capture emissivity and reflections.
  • Our eye can see through a glass.
  • Thermo energy cannot pass through glass.

It is very important to understand that Thermo Images are just for Surfaces, It doesn’t penetrate the objects neither bodies.

Every surface has different emissivity, depending on their surfaces.

Shiny surcafes has high reflectivity and low emissivity

Dark (opaque) surfaces has low reflectivity by high Emissivity

In the picture below can be noticed that emissivity is affected by surface colors.

In the Solar Panel generations business, Thermo inspection has a great role.

The more energy the panel absorb, the more efficient it is.

According to statistical analysis from various thermo experts, performing regular Thermo inspections can help to reduce energy loss by 15%, due to Broken cells, dust, and dirt.

As a bonus, we have included the emissivity tables we use for our inspections:
