Workers have been praised after a huge oil platform project was completed.
The Cygnus Alpha Compression Module (ACM) was the last of four main structures to leave Heerema Hartlepool after two and a half years of construction.
The Cygnus Bravo Wellhead Platform (BWHP) and the Cygnus Alpha Process & Utilities (APU) topside left earlier to the final offshore destination in the Southern North Sea. The key infrastructure, being the Cygnus Alpha Wellhead Platform (AWHP), sailed in May.
The Cygnus field consists of two drilling centres, the Alpha and Bravo.
Heerema Hartlepool received the frame agreement from operator GDF SUEZ E&P UK in August 2012 for the construction of three topsides, a compression module, with two bridges to connect the three Alpha platforms and a flare tower for the Cygnus field.
Koos-Jan van Brouwershaven, chief executive of the Heerema Fabrication Group, said: “Within a period of two and a half years we have successfully delivered three topsides and a module from our Hartlepool yard.
“During the fabrication of the topsides we implement the design changes. This shows the strength and flexibility of our organisation when it comes to building complex structures. During the peak period of this project over 2,000 people worked on our Hartlepool yards, where we successfully finished the project safely without major incidents.”
