Foreword

This BritishStandard has been prepared under the direction of the

Shipbuilding and Marine Standards Committee and is based on a proposal of

the British Ship Research Association.

Ships require a means of ship to shore access which can be safely used by all

persons. The aluminium shore gangway provides a lightweight convenient

structure which can be used in a horizontal or inclined position up to an angle

of30° from the horizontal dependent on tidal or freeboard conditions. Special

designs of step allow for a more severe angle to be employed than the30°

specified. The gangways described in this standard are not intended to carry

wheeled traffic such as loaded trolleys, etc.

A lightweight gangway for “first person ashore” is described in Appendix A.

NOTEUsers of this BritishStandard should note that while observing the requirements of the

standard they should at the same time ensure compliance with any statutory requirements, rules

and regulations as may be applicable to the individual ship concerned.

A British Standard does not purport to include all the necessary provisions of

a contract. Users of British Standards are responsible for their correct

application.

Compliance with a British Standard does not of itself confer immunity

from legal obligations.
