FLOOD PREVENTION DOORS

Special customized doors on several configuration shapes providing flexible solutions for the convenience of loading / unloading

vehicles, on Ro/Ro and Ferry ships.

These doors divide the car deck into watertight compartments with longitudinal or transverse barriers. They prevent the free water

from spreading over the whole car deck, and thus decrease the total free surface effect and its potential to capsize the vessel.

The survivability of Ro/Ro and Ferry vessels is substantially improved.

These type of doors are designed to bring the vessels into line with the Stockholm Agreement for vehicle / passenger

ferries, particularly for existing ships and new vessels too.

Doors can be designed to any water pressure and can meet

any specific requirements from the classification societies.

We can provide multifold configurations structures to solve

questions such as: hoistable car platforms above doors,

inboard ramps underneath door’s location, etc.

It is quite important that we can arrange all operational

systems placed onto the door sections, minimizing the

installation cost.

All doors and electro-hydraulic equipment, are built, tested

and adjusted in our factory plant.

Innovated solutions with very low sills up to 30mm.

Following are some alternative types of these doors,

depending on an operator’s needs.

Single Hinged Manual Operated & securing by swing nuts & turnbackles

Electro-hydraulic Operated

Hinged Single Panel: 180o rotating

(Pivoting Type)

The door consists of one panel,

located at the shipside, swinging

90o fore or aft to its open position

parallel to the shipside.

Door-set is fully hydraulic operated,

lifting, swinging and securing in close

position by stoppers and locking

devices, through PLC controls.

There is a rubber seal along the

door-leaf and frame that provides the

water tightness of structure.

An access hinged door is fitted into

panel as an integrated part of the door

system.

Electro-hydraulic Operated of 4,10m Height

Electro-hydraulic OperatedTwo Single Swinging Doors with vertical pillar bar in the middleDoors follow deck’s camber

Hinged Double Panel: 180o rotating.

Two (2) individual panels stowing at the side shell port & stbd or center casing, swinging 90o fore or aft to its open position.

The door-set is fully hydraulic operated, lifting, swinging and securing in close position by stoppers and locking devices in a

multi-configuration, actuated by PLC commands.

There is a rubber seal perimetrically door-leaves and frames /deck coamings to achieve water tightness.

An access hinged door is fitted into panel.

Electro-hydraulic Operated Double Leaf Door Swinging 90o AFT

Electro-hydraulic Operated Double Leaf Door Swinging 90o AFT & FORE Breadth sealed 8,5m

Side-Hinged & Sliding Door: 180o swinging.

The door-set consists of one pivoted leaf and one sliding leaf, stowing at the ship side of the vessel and its closing

position is across the vehicle space.

During the pivot leaf swinging 90o fore or aft, the sliding leaf is accommodated to it and when door-set reaches vertical the centre

line the sliding leaf starts moving to close position, forming a transverse barrier across the garage.

This compact design provides a unique solution to vessels as they can load and unload

vehicles without maneuvering confusion and also saving valuable time.

Electro-Hydraulic Operated Swinging 90o AFT & FORE Breadth sealed 12m

11

During Rotation

It is quite remarkable that we can

easily divide the vehicle lanes for

pivoted or sliding sections,

depending of vessel’s

convenience.

It is totally hydraulic operated,

lifting, swinging, sliding and

securing in a multi-way.

Adjustments and arrangements

can be done through PLC

controls.

A packing seal secure water

tightness between door-leaves

and frames /deck coamings.

An access water tight door is

fitted into panel.
