The importance of using proper instrumentation Electrical and mechanical instrumentation invovles design, control and implementation of devices that can measure physical quantities. There is a huge amount of thought behind the proper instrument and installation choices for each small or larger measuring point. All vessels generally use state of the art instrumentation and equipment to manage everything from the engines, steering and navigation system. When the equipment malfunctions it can have a huge impact on the operational efficiency and can cause massive downtime that can put the vessel behind schedule. A broken viscoity sensor can cause wrong engine combustion, wrong additive dosing can reduce fuel efficency or worse; lubrication properties of various lubration oils. A ballast that isnt filled appropriately after loading can impact vessel stability and leaks and dangerous pressure levels in fuel tanks can impact enginre operation or even lead to disaster.
