Watertight bulkhead door system for all types of ships.

TEBUL OY has been designing and manufacturing watertight bulkhead sliding doors since 1961.

Our self-tightening watertight bulkhead sliding door is a fourth-generation product.

The door unit consists of the door blade, door frames, fully electric transmission mechanism, control device and associated cables.

The primary self-tightening is based on metal to metal contact with rubber seals for initial tightening. The higher the pressure, the larger the force exerted on the door.

Tebul doors are appoved to be installed into A-60 bulkheads.

Tebul doors are available also in the Eex-version, for Explosion Hazardous areas.


TEBUL OY was established in 1942 for the production of hydraulic machinery and equipment for the shipbuilding and other industries.

The first ship steering gear was delivered in 1952, and the first watertight bulkhead doors in 1961. Today, watertight bulkhead sliding doors are the main product of TEBUL OY.

The company was merged with Wärtsilä in 1964 and emerged as an independent company again in 1988, following the reorganization of the former Wärtsilä Marine activities. The present company structure was established in 1992.

Strict quality-control and assurance procedures are applied by TEBUL OY throughout planning, production, installation and service as part of the total adopted Customer Commitment policy.

We have delivered over 5000 watertight bulkhead sliding doors over the years.
