This isometric shows an open wing tank and adouble bottom of a Ro-Ro passenger ferry.
The cross-over line is visible as an open line between the portside tank and the starboard tank .A cross-over in this case is designed to be used in the event of a collision.Water entering one space will flow to the tank on the other side.This will moderate the list.

5.Cross-over line
The system can result in reduced damage stability requirements.The majority of ferries and passenger liners have such a crossover system.
Thedrawings show :
-Bilge wells : fluid present in the compartment will flow to the bilge well and can then be removed by the bilge pumping arrangement.
-Heating coils: these are in the heavy oil tank .If the oil is too viscous to be pumped .it will be heated up to a safe viscous temperature.

6.Bilge strake,approximately 10 mm thick
7.Backing bar
8.Bilge keel,approximately 220*15 mm (for this particular ship)The bilge keel is welded onto a flatbar.When damaged the bilgekeel should break off,with the strip remaining attached to the shell.
Without backing strip, a crack in the bilge keel could continue into the bilge strake, and that is dangerous!

the bow is the part of the ship between the stem and the collision or forepeak bulkhead, and the adjacent part aft of the forepeak , to the parallel mid body. The space forward of the collision bulkhead and below the maindeck,is the forepeak. The forepeak tank is the lowest space in the bow and is often divided in a lower and an upper forepeak tank. The forepeak tank is usually used as a ballast tank is usually used as a ballast tank.If the ship is not loaded this is often filled with water to increase the draught and to reduce the trim by the stern. Usually there is a wash-bulkhead at the centre line in the peak tanks.This prevents sloshing (the fast movement of water from port to starboard) when a tank is partly filled.It also improves the rollingbehaviour of the ship. Directly behind the forepeak there can be another tank (deeptank) that extends from starboard to port and from the bottom to the deck ,used for ballast or fuel.
In the top of the forepeak, right below the anchor windlass there are chain lockers for the storage of the anchor chains.Above the weather deck in the bow there is often a gorecastle, a superstructure from bow to at least above the collision bulkhead .Sometimes extended further aft,to even aft of number one hatch.The forecastle is protected against overcoming sea by a bulwark.On the forecastle is the windlass and other morring equipment.The foremast is usually located at the after part of the forecastle-deck. The forecastle can be divided into: -Stores and workshops for ship's maintenunee: -tool for work on the deck (bosun's store,carpenter's store) -storage for paint (with fixed fire-fighting equipment) -storage for ropes
