Offshore project and engineering company Semco Maritime has been awarded an EPCI contract with Total as part of the Tyra Redevelopment Project in the Danish North Sea.
The work scope includes preparatory engineering work followed by system installation on five unmanned satellite platforms at the Tyra complex, Semco Maritime said on Thursday.
Initial planning work has begun, and the entire project – involving approx. 25 employees – must be completed by October.
The Tyra Complex consists of two central processing platforms, Tyra East and Tyra West, and five unmanned satellite production platforms. While the processing platforms are to be completely redeveloped, the five satellite platforms are put into idle mode during the redevelopment phase. The satellites must be able to perform minor operations and allow for maintenance, inspection and preservation of equipment.
Semco Maritime’s scope of work also includes installation of temporary diesel generators on several satellites, and isolation of process systems in order to provide a safe working environment at Tyra East and Tyra West.
During the installation period, two teams of Semco Maritime specialists accommodated on walk-to-work vessels will work in 14-day shifts in order to deliver in due time and quality, says Claus Ross Eilersen, Director, Projects and Services, Semco Maritime:
“We are excited that Total has chosen Semco Maritime to take part in this epic redevelopment project with huge positive impact on Danish energy supply. It is a very challenging project involving numerous parties from around the world, making cooperation, quality and punctual delivery even more important,” said Claus Ross Eilersen.
In addition to the scope of work of this order, Semco Maritime also provides several kinds of services to Total, including preventive maintenance, fabric maintenance, EPCI-contracts and manpower.
The Tyra project
The Tyra field has been the most important gas field in Denmark for decades, processing 90 percent of national gas production. During the years, the platforms has subsided more than five meters. The complex now has to be redeveloped to secure production for the next many years.
The new facilities will be located approximately 139 miles (225 kilometers) west of Esbjerg, Denmark in the North Sea. The Tyra gas field is the center of Denmark’s national energy infrastructure, processing 90 percent of the nation’s gas production. First production from the field was achieved in 1984.
An investment of approximately 21 billion DKK for the redevelopment of then Maersk Oil-operated Tyra gas field was approved at the beginning of December 2017. This will enable Tyra to continue operations for at least 25 years.
McDermott cut first steel marking the start of fabrication for Total’s Tyra Redevelopment project in October 2018. The steel cutting ceremony was held on Tuesday at McDermott’s fabrication yard in Batam, Indonesia. McDermott was put in charge of fabricating and assembling two separate work packages for Total, comprising of seven topside structures, six connecting bridges and six jacket extensions weighing a total of 36,300 tons (33,000 metric tons).
