Marine Propulsion Systems

move ships through the water, ensures a better safety standard for the  marine ecosystem

and are cost-efficient. Worldwide goals have been set for emission reductions for the

maritime sector.
    "The IMO is targeting a reduction in the carbon intensity of international

shipping by at least 40% by 2030 compared with 2008 levels, and by 70% by 2050. The IMO

took this action to support the United Nations Sustainable Development Goal 13, to take

urgent action to combat climate change and its impacts."
    The most commonly used type of marine engine is the reciprocating diesel engine that

has a higher efficiency compared to other models. These engines can be classified into

three types based on their revolutions per minute (rpm).
    The three categories- slow, medium, and high speed have their own benefits based upon

the type of ship to be powered.
    For instance, large ships require a low speed but high torque propulsion system to

power them. For such vessels, a low output speed engine can be selected.
    The issue with using slow-speed engines is the large space they take up as compared to

the other engines. Thus, a space-effective solution would be to install high-speed engines

in the ship, and then reduce the torque before it reaches the propellers.
    For this, a gearbox is a very useful component that can be used to manipulate

rotational torque transfer. It is attached to the Marine Propeller Shaft and reduces the power transmitted to the

    The slow speed engines pose no problem to the transfer of torque and do not require an

additional gearbox. The gearbox in the other speed engines is attached in between the

intermediary and propeller shafts.
    Our company produces a full range of standard and customized

Marine Deck Equipment and winches.

Available systems include horizontal and vertical windlasses, winches and winches for

various applications. The available models can be constructed according to applicable

commercial standards.
    All of our Marine

designs have been specially developed and improved for operation in the marine

environment. All structures have been designed to take up heavy lateral forces and to have

a low value of elastic deflection under load. All parts have been designed and protected

for easy maintenance.
    Threats are posed by inputs of persistent pollutants (for example substances that are

non-degradable or not readily degradable in water) and excessive nutrient inputs via

rivers, as well as the widespread transport of pollutants via the atmosphere (see info:

Environmental Status of European Seas). As a result, organic pollutants such as

polychlorinated biphenyls (PCBs), which were formerly used as insulation, hydraulic or

cooling fluids, can be detected in remote polar regions. Other hazards to the marine

environment are caused by shipping (for example illegal disposal of wastes, accidents,

problems caused by antifouling paints) and inputs of oil and pollutants from the offshore

oil and gas industry. Marine ecosystems are also endangered by overfishing and other

negative effects of fishing on marine species and habitats. A further threat is that of

climate change and entailing effects such as sea level rise and shifts and changes in flora

and fauna of certain sea areas.
    As pollution of and processes in the oceans do not stop at political borders,

successful Marine

Environmental Protection
can only be achieved by means of intensive international

cooperation at regional and global level.
    The various advantages of advanced outfitting are as discussed below:
    1. Shorter Cycle Time: Since

Marine Outfitting Equipment
is done in parallel to hull fabrication, the total cycle

time, that is, from the date of contract signing to the delivery of the ship, is reduced

considerably. Accordingly, more number of ships can also be built in a year, therefore

giving leverage to the productivity of the shipyard.
    2. Better Working Conditions: Since outfitting in block stage is carried out in a

workshop atmosphere, the efficiency of the work force will be more because of the improved

lighting and better ventilation. Modern shipyards also incorporate efficient human factors

to ensure optimum level of workshop productivity.
    One of the primary reasons for dock injuries – and in some cases fatalities – are

Marine Mooring Equipment lines.

Many of these incidents see what is referred to as snap back occurring, a process in which

a sudden release of energy causes the two ends of the line to recoil or ‘snap back’ with

high speed and force – causing individuals within the proximity to be struck by pieces of

    Throughout the years many such mooring line incidents have occurred, leaving

individuals with serious injuries, from these accidents 14% have led to fatalities.
    Alongside this, injuries can occur from individuals being hit by parting ropes,

equipment being old and faulty or the wash of other ships passing by causing mooring ropes

that have not been correctly tied to snap off.
    Lifeboats are the primary

Marine Life-saving Equipment
used when the crew and passengers are supposed to

‘abandon’ the ship and need out of water support. They must be available in sufficient

quantity and support the required capacity and size such that the total number of persons

on board can be evacuated from either port or starboard. ( This is done so that in case the

ship is capsizing to one side, say port, the lifeboats can be lowered from the starboard

side and everyone on board can be saved.)
