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.

Most of us has been affected by corrosion our boats.
There are different types of corrosion affecting our boats:
In simple words, Corrosionis 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.
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.
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:
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.
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.
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.
ROVs allow us to investigate areas that are too deep for humans (divers) to safely reach themselves.
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.
