Abstract
Abstract A process to prevent tilting of a ship''s hull during loading and unloading of comparatively heavy cargo units by means of the ship''s own cargo gear, using at least one supporting leg mechanism on board the ship to support the ship against a top face on a quay and using a manometer in said mechanism to control that a positive load is applied continuously in said mechanism against said top face provided mainly by trimming the ballast tanks of the ship. A supporting leg mechanism provided with a manometer and means to adjust the mechanism in relation to the quay level.

Independent Claim
157 words
A process of counteracting a tilting of a ship''s hull during loading and unloading of heavy cargo units by means of the ship''s cargo gear and by means of a supporting leg mechanism which engages a stationary, horizontal supporting surface outside the ship, characterized by using at least one adjustable supporting leg mechanism, which after being swung outwardly from an inoperative position on board the ship and after having engaged a horizontal surface on a quay which is at a variable level above the waterline of the ship, and while stating the load via a manometer on or in the supporting leg mechanism when said mechanism is subjected to an initial load and later on when subsequent stresses are exerted by the cargo unit on the ship''s cargo gear, is subjected to a further controlled load which is regulated mainly by ballast trimming, and in part by mechanical adjustment of the load in the supporting leg mechanism.
Claim 2
