ECONOMICAL SPEED – SLOW STEAMING / SUPER SLOW STEAMING a) Full Speed The ship’s speed achievable at the Normal Continuous Rating (NCR) of the main engine which is normally 85% of Maximum Continuous Rating (MCR), 90% of thermal load with the exception of some vessels where the engine maker has determined NCR as 90% MCR….
This procedure applies to all vessels equipped with Exhaust Gas Cleaning System. Exhaust from the below equipment is connected to the EGCS: · Main Engine · Auxiliary Engines · Boiler* (as applicable) RESPONSIBILITIES Master is responsible for: · Requesting local regulation from agents for any restrictions for uses of EGCS and discharging its wash water/effluent…
The future of shipping industry rests with cleaner and more efficient fuels. Use of cleaner sourcelike LNG/ LPG as an engine fuel is fast growing globally. Main engines designed for dual-fuelengine are going to be more dominant in future as more stringent air pollution and Emissionsregulation are schedule to come into force. Engines can use…

Master must ensure that all statutory, class and trading certificates are kept valid at all times. Apart from above certificates, vessel will also maintain following below certificates in Master’s file. If the vessel has been issued with multiple load-line certificates, only the current certificate should be kept in certificates file / folder; non- applicable certificates…
It should be remembered that the brake holding power is always greater than the heaving power and that once the brake starts to slip it is impossible to heave unless the force causing the slippage is reduced. Risk of injury arising either from premature rendering or from winch not rendering at design pressure leading to…
Man overboard is a potentially dangerous situation for a ship at sea. Among the many threats that could undermine the proper course of the voyage of a vessel, accidents related to man falling overboard is one of them. Unfortunately, according to a report, a high percentage of all overboard incidents end in death. It is…
Piping system The bilge system is used to remove small quantities of fluid that have leaked or condensed into a dry space. The system serves the machinery spaces, cargo holds, cofferdams, voids, stores, tunnels and pump rooms. Each space has its own piping but the pump is likely to be shared. Features of bilge system…

Oil Fired Auxiliary Boilers The oil fired auxiliary boilers are not fitted with sootblowers. Soot removal from the heat transfer surfaces of the tubes is carried out by means of a water jet when the boiler is not in operation. The need for soot removal may be determined by the following procedures: • Visual inspection…
