RAYNES JETTY

OVERVIEW

Topbond were appointed to develop an innovative method to deliver the construction of a new bull nose fender to the jetty head. The exposed coastal nature of this jetty, where vessels have been written off due to bad weather and sea conditions made this a challenging environment to work within.

THE CHALLENGE

To limit marine vessel requirement and to keep costs to an absolute minimum whilst maintaining a safe working environment Topbond decided to deliver, fix and test an adequately sized hiab to the end of the jetty with one vessel movement.

THE SOLUTION

A scaffold access system and temporary support were installed to enable the existing timber bull nose to be removed. The installation of the hiab enabled all lifting operations to be carried out from a stable platform eliminating the need for an expensive jack-up barge or a floating barge which would be vulnerable to weather/sea conditions. A new steel bull nose was installed with a welded frame, GRP deck and all steel tube - timber pile connections made with concrete pumped from the shore.
