Design of Doha metro Red Line North
› The Red Line North is the first of four underground packages which is a part of a wide-ranging plan to realize a new transportation infrastructure in Qatar.
› The Red Line North extends over a distance of approximately 13 km from Mushaireb station in the Qatari capital.
› The scope of work includes design of 11.6 km of twin bored tunnels and design of 7 new underground stations.

Client consultancy on Northern Europe's largest aquarium
› With its 9,000 m², the Blue Planet is Northern Europe's largest and most modern aquarium
› The Blue Planet is one of the few aquariums in the world that can show wildlife from all around the world. This is due to the extensive water treatment systems that can deliver hot and cold saltwater as well as freshwater
› The visitors can therefore experience changing organic expressions as they move through the vortex building, with a variety of exotic themed exhibitions.

Oslo International Airport, Norway
COWI in a Joint Venture designs a major expansion of the Oslo International Airport.
› The Gardermoen airport is extending the passenger terminal building, and building a new pier with 19 new aircraft stands, a new taxiway system and a redesign of the forecourt areas.
› The major expansion brings the capacity from 20 to 28 million passengers in the first phase and further
› The requirement regarding energy consumption is a 50% reduction compared with the existing passenger terminal from 1998.

› Upending tool under development by IHC (during Race Bank OWF)› Designed for 6.5m MPs, whats next?

Agenda
09-03-2015DANISH WIND INDUSTRY ASSOCIATION31
Monopiles
- DONG asked COWI to investigate whether local shell buckling of MPs during installation (impact driving) was an issue
- Offshore guideline limitations:
- NORSOK N004: D/t<120
- ISO19902: D/t≤120
- EN 1993-1-6: 20≤r/t≤5000
- (LBA, MNA, GNIA, GMNIA)
Buckling analysis
09-03-2015DANISH WIND INDUSTRY ASSOCIATION32
- Non-linear geometry
- Elastic-perfectly-plastic material behaviour for structural steel
- Non-linear boundary conditions (soil) including viscous damping
- Imperfections explicitly modelled when applying GMNIA method

Offshore Foundation Driller (OFD) Alternative(upgraded) BSD3000 for soft soils?
under construction by Hochtief GmbH
XL Monopiles
Key Issues:
- Developed for MPs above OD=7.0m
- Reduction in noise compared to driving
Deeper waters seems to be required due to height of the OFD?
