LOGSTOR insulated Singlepipe® system successfully laid by Technip’s APACHE vessel

In 2013, Maersk Oil and the partners in Danish Underground Consortium approved an USD 800 million investment in a new wellhead platform in the Tyra Southeast field.
It is the kind of investment needed to secure the future of Danish Oil and Gas production and is contributing positively to Denmark’s economy and employment.

It is the kind of investment needed to secure the future of Danish Oil and Gas production and is contributing positively to Denmark’s economy and employment.

Maersk awarded Technip the EPIC contract (Engineering, Procurement, Installation and Construction) for the WPC Rolf Project. The APACHE vessel was selected to lay the pipes.

Project WPC Rolf

Operator: Maersk Oil
Client: Technip
Year: 2015
Region: Europe – North Sea
Country: Denmark
Water Depth: 45m / 148ft
Lay Method: Reeling

LOGSTOR Oil & Gas then received a contract award from Technip in 2014 to produce and supply the following:

  • Reception of carbon steel - 3LPP coated pipes.
  • Flowlines insulation: 18km of 8” OD pipes.
  • Bends insulation: 9 bends of 8” OD and 9” OD.
  • Spools Filed Joints: 23.
  • Delivery to Orkanger (Norway) spoolbase.

The pipes were insulated during the first quarter 2015 and then delivered at the spoolbase where contractor welded the stalks and applied IMPU field Joints before further installation by reel lay. Bends and spools are produced during summer 2015.

LOGSTOR supplied for the project its SinglePipe® - thermal insulation solution (dry insulation) with the following properties:

  • Thermal Coefficient (U-value) of 2.5 W/(m2K).
  • Foam density of 300kg/m3.
  • Flowline total coating thickness of 31mm (3LPP@3mm, PUR@21mm & HDPE@7mm).
  • Bends 8” total coating thickness of 37,3mm (Flame Spray 2LPP@3mm, PUR@21mm & HDPE@7,7mm).
  • Bends 9” total coating thickness of 40,7mm (Flame Spray 2LPP@3mm, PUR@21mm & HDPE@7,6mm).
  • 23 Field Joints on spools.

Technip spooled the SinglePipe® on the Apache vessel. They were successfully laid offshore end of June 2015.

Benjamin Buhot, Technip Category Manager for Welding & Coating - Subsea Procurement, mentioned that “there were  not a single damage to the LPC during spooling and stalk handling”  He confirmed that “all operations went fine and that FJC solution with IMPU provided a robust overall coating system with good production performance as well.

He concluded with these words :“Bottom line is that the product is very satisfactory !”

Thank you to all Logstor departments who contributed to this success
