Video survey research has proven to be a powerful tool that can be used across all industries and cover a wide range of topics in order to identify consumer tastes and opinions as well as demographic and social information. Historically, researchers have relied on classical in-person qualitative methods to conduct their surveys. These surveys were valuable to the extent that they could capture non-verbal expressions from respondents such as hand gestures, colloquialisms, and tone of voice. However, this data was very slow and expensive to collect and analyze.
Photographic surveying also called photograph icing is a method of surveying in which plans or maps are prepared from photographic taken at suitable camera stations or photographic is the science of making measurement from photographs.

Hull cleaning requires divers to clean the bottom of a boat without damaging the coating or scraping off the paint which is a difficult task to accomplish and requires technique and knowledge of different boat paint coatings.
MARINE ENGINEERING WERKZ has a new approach to propeller cleaning. The traditional approach in the industry is to let the propeller get good and fouled and build up a calcareous growth and maybe polish it in the water once or twice a year or in drydock. This polishing is done with a grinding disk and can be quite damaging to the propeller. By the very fact of using a grinding disk, a substantial amount of metal is removed from the propeller itself. This can alter the shape and efficiency, cause roughness and increase rather than reduce friction. It can also be a source of marine pollution which is a problem in a number of ports.
