The Basic components of an ROV

ROV' consists of several major common components weather they are small or large these components are generally the building blocks of the generic ROV . In the past the basic building blocks of each individual design of ROV has varied wildly but as technology and off the shelf components are becoming more suitable to use in the construction of ROV's the general trend in the design of ROV's that the Typical ROV uses the same components as the next.
The drive for the use of off the shelf components for the building of ROV's started in the early eighties when several ROV operating companies revolted against the ROV manufacturers and laid down specific specifications to be included in these ROV designs. The trend has continued and today several ROV operators are also the manufacturers of their own ROV equipment. such as Subsea offshore with the Pioneer and Examiner ROV's or Oceaneering with the Magellan ROV. The advantages to the operators are obvious they have in-house expertise to trouble shoot ROV related problems and they can change / modify the ROV's at will for different types of Underwater tasks. The other main advantage is the cost the reduced cost of manufacturing your own ROV's gives the edge in competing for ROV contracts.
Another advantage to the parts and subsystems being off the shelf is that there is more available expertise available to operate , repair and maintain the equipment.
I have divided the next few sections of this "Book" into the larger components of ROV's that are common to them all.
