Repairs were required after a small bulk carrier lost steerage and collided with one of the berthing dolphins at the Immingham Oil Terminal , one of the UK's major oil importing terminals.

Humber Oil Terminals Trustee Ltd engaged civil engineering consultants High-Point Rendel to develop and evaluate possible methods of repair.

Alternative solutions were developed and agreed, tender documents prepared and after due process of evaluation, Herbosch-Kiere was appointed to undertake the work at a tender price below £1 million.

The work comprised dismantling the dolphin's steel superstructure enabling repairs to be carried out, driving a new 45m long, 1.8m diameter pile, removing the damaged pile (one of five in the dolphin) and reconstructing the dolphin superstructure. A short period of berth occupation was required to undertake the works.

Herbosch-Kiere mobilised its multi-purpose crane ship Atlantis , commencing work on 17 November 2003. The work was completed during the evening of 19 December and the berth re-commissioned to receive its first tanker in the early hours of the following morning.

High-Point Rendel acted as Engineer for the works, assisting the team in a proactive approach to all operations which ensured that no recordable accidents or incidents occurred.
