Abstract

As part of the future modernisation and upgrading of the Marine Terminal facilities of the Esso Fawley Refinery, it has been proposed to install a loading arm on Berth 6 to replace the existing detachable hose, for loading and unloading of the cargo.

The T shape deck slab is centrally supported by an 11 metre (36 feet) outer diameter caisson and the flanges are supported by 813mm (28 inch) diameter piles. The overall thickness of the deck slab is 440mm (17 1/2 inch). The proposed loading arm shall be located 2 metre inward from the sea side face and 1.75m off centre.

The initial scheme was to strengthen the deck slab in order to support the additional loads from the loading arm. This would have lead to a major modifications to the deck slab. As an alternative proposal, Finite Element analyses have been performed to determine the forces and moments developed in the slab due to the applied loads from the loading arm which have been distributed in larger area by using a spreader grillage.

The results thus obtained have been compared with the ultimate strength of the deck slab calculated by using BS 8110. This comparison indicated that the existing slab has reserve capacity to carry the additional loads from the loading arm and any major modification to the deck slab is not required.
