LED makes its way across more and more in Marine/ Industrial applications. In today’s maritime industry, the term ‘Energy Efficiency’ is of sheer importance in all aspects of shipping operation. From main engine to cargo operations, energy efficiency has become the base to set up and plan any machinery or procedure. Electrical system being the most important network onboard ships, it is important for ship owners and operators to make their energy efficiency plans considering the same. Use of energy efficient LED lighting in place of conventional lamps and tube lights on ship, contributes to more savings and add up to its energy efficiency model. An incandescent globe (bulb) can provide a life span of 1000 hrs and a fluorescent lamp can be used up to 7500 hrs. However, far better performance can be achieved by LED lights which have lifespan of about 50,000 hours and 60% less energy consumption. Implementing this would not only reduce the maintenance hours but also bring down the operat

  Life rafts are survival equipment provided as a life-saving appliance on every seagoing merchant or passenger ship, in addition to the  lifeboats . Life rafts are much easier to launch than lifeboats. In emergencies, evacuation from the ship can be done without manually launching any of them, as the life rafts are designed with an auto-inflatable system. SOLAS Chapter III  gives all the details for types and the number of life rafts to be carried as per the size and type of the ship. Where Are Liferafts Located On Ships? Life rafts are normally located on the muster station, on the port and starboard side near the  lifeboat , and fwd and aft of the ship. The location generally depends on the size of the ship. Life rafts are stored in a fibreglass container, with a high-pressure gas used to inflate life rafts during an emergency. A Hydrostatic Release Unit (HRU) is connected to the raft container and ship, which releases the raft even after the vessel sinks in water. The parti

International maritime signal flags are various flags used to communicate with ships. The principal system of flags and associated codes is the International Code of Signals. Various navies have flag systems with additional flags and codes, and other flags are used in special uses, or have historical significance A Alfa - Diver below (when stationary); I am undergoing a speed trial B Bravo - I am taking on or discharging explosives C Charlie - (affirmative) D Delta - keep clear of me, I am manoevering with difficulty E Echo - I am altering my course to starboard F Foxtrot - I am disabled, communicate with me G Golf - I require a pilot H Hotel - I have a pilot on board I India - I am altering my course to port J Juliett - I am going to send a message by semaphore K Kilo - you should stop your vessel instantly L Lima - you should stop, I have something important to communicate M Mike - I have a doctor on board N November - no (negative) O Oscar - man overboar
