Hull of a Ship – Understanding Design and Characteristics

 Hull of a Ship – Understanding Design and Characteristics


Bow and Stern: The forward most contour of the ship’s hull is called the bow, and the aft-most, its stern. The stem is the forward most contour part of the bow.


Forward Perpendicular: If a perpendicular is drawn at the point where the bow intersects the waterline, this imaginary perpendicular line is called the forward perpendicular. For most of the hydrostatic calculations, the forward perpendicular is used as the forward reference of the hull.


Aft Perpendicular: Depending on the designer, the aft perpendicular can be the perpendicular drawn through the aft side of the rudder post or through the center-line of the rudder pintles. The aft perpendicular is the aft reference line for all hydrostatic calculations.


Length between Perpendiculars: The length between the forward and aft perpendiculars is the length between perpendiculars. The LBP is a very important parameter in all stability calculations, hence calculation of the LBP at various drafts becomes an important step in carrying out stability analyses.


Sheer: The upward curve formed by the main deck with reference to the level of the deck at the midship, is called sheer. It is usually given to allow flow of green water from the forward and aft ends to the midship and allow drainage to the bilges. The forward sheer is usually more than the aft sheer to protect the forward anchoring machinery from the waves.


Summer Load Line: The summer load line is the waterline of the ship at sea water when it is at its design weight and ballast conditions. It is also called the design draft; this forms the reference for all other load lines of the ship.


Length of Waterline: The length of the ship’s hull at the summer load line is the length of waterline for the ship. This length plays an important role in the calculation of hydrostatics of the ship, as well as propeller design calculations.


Length Overall: The length between the forward-most and aft-most point of

What is INDos NO and advantages of having INDos number?

What is INDos NO and  advantages of having INDos number?  Published by akash sharma(seafarers  guideline)  on 16/08/2021 This is one such certificate Which is applied for seaman only through DG APPROVED COLLAGE When we go to do any course to join merchant navy, first of all collage applies for this certificate. Inside it the following essential things of the seaman are shown such as :- :- seafarers personal details :- Course details that have been done from the collage :- sea ​​service experience :- medical details :- document details like( cdc/wk/cop/dce) :- Documents to be uploaded on time  MEANING OF INDOS NO :-  INDos number stands for Indian National Database of Seafarers. A complete INDos number includes a seafarer's full name, address, photographs, signature, telephone number, qualifications etc. It is made of eight alphanumeric characters and can provide as a means to crosscheck a seafarer's identity.   Apply now for indos click here INDos Number and its Benefits to Ind

INDIAN CDC and what is INDIAN CDC/CDC

Indian cdc and what is it ! Hey guys hope all are very well  This is AKASH SHARMA, should we discuss about Indian cdc What is Indian cdc and what is its value in shipping line, only a seaman can understand this. Do as many courses as you want, till you don't have cdc, you are half and incomplete seaman. To apply cdc you will need to do proper course only after that you can apply cdc First of all it should be known that what is cdc CDC APPLY NOW/HERE Let us know what is cdc - cdc ( continue discharge certificate) different cdc of different country Like INDIAN CDC, PANAMA CDC BELIZ CDC SAMAO CDC and many more It is very important for a seaman to have When seaman goes to ship there are some important things which are updated on cdc Update on cdc for example :-  ship's stamp seaman's sign on date seaman's sign off date seaman's total ship time and ship's captain's coc number and captain's stamp  After all these updates on the cdc we can easily guess that th

Information about all ranks in merchant navy

  Beginner's guide to merchant navy ranks/Information about all ranks  :- Any industry requires a progression among the staff to keep a smooth coordination of tasks and advance legitimate administration techniques. The equivalent goes for the Merchant Navy. The terminology of trader naval force positioning framework is worldwide acknowledged by delivery organizations and business vessels all throughout the planet. Be that as it may, there can be minor changes in names and obligations doled out to explicit positions relying upon the country to which the boat has a place. (Note:- contact us for marine documents work by :- adsharma716@gmail.com) As a rule, the positioning framework on trader vessels is principally separated into the accompanying classes: 1. Deck Department 2.  Engine Department 3.  Catering Department The extension of a boat is the route center point fitted with cutting edge hardware frameworks for the protected route of the boat. Henceforth, it is needed to b
