vertical sliding door

Doors in the side shell are a feature of almost every type of ship and are
employed for various duties, the most common being passenger access, pilot
entry and bunker hose connections. For opening, the doors can be sidehinged,
top-hinged or, as featured here, arranged to slide vertically upwards.
TTS Ships Equipment vertical sliding doors are located on the inside of the
shell plating and slide up and down in guides. When the door approaches its
lower, closed, position, the guides direct it diagonally so that its outside
plating is flush with the ship’s shell.

Opening and closing of the door is achieved hydraulically, the most
common method employing a jigger winch assembly, with an alternative
system using a direct-acting cylinder.Whichever operating system is used,
the door is safely secured in both its open and closed positions by hydraulic
wedges fitted to the ship’s hull.
Some classification societies require shell doors to be fitted with a
strong-back.This is met in full by TTS Ships Equipment vertical sliding
doors which, if necessary, have the strong-back built-in, ensuring safe and
reliable service. Fireproofing and insulation can also be built-in if required.
Shell doors, which may be of either steel or aluminium, are constructed
of plates and profiles employing classification society-approved materials.
They are designed to fit flush with flat or curved hull sections according to
their location.The highest standard of weathertightness, according to the
latest rules, is assured by a rubber gasket which provides an all-round seal.
Generally,TTS Ships Equipment vertical sliding doors are supplied as
complete units, including the guides and coaming.This coaming comprises
about 500mm of plate surrounding the door opening and provided with
the necessary stiffeners welded in position.This enables a shipyard to
quickly and easily install the door into the hull aperture.To reduce
hydraulic pipe runs to a minimum, a small hydraulic power pack can be
located adjacent to the door, further simplifying installation.
Operation of the door is effected through manoeuvring valves, which
may be either manually operated or automatically controlled by means of
pushbuttons, as specified.An operating stand is positioned close to the
door and incorporates a panel with an LED display to indicate the
locked/unlocked status of the door. If required, a remote display can be
supplied for installation on the bridge to indicate when the door is fully
secured and cleated.
TTS Ships Equipment also makes other forms of side doors (top-hinged
and side-hinged)
