Aker Solutions ASA, a Norwegian oil services company headquartered in Oslo, provides oilfield products, systems and services for customers in the oil and gas industry worldwide. The company, with roots back to 1841, was known as Aker Kværner prior to 2008.The predecessor company, Aker Kværner was founded in 2004 as the result of a major restructuring of a complex 'Aker Kværner' business unit, formed originally in 2002 by the merger of Aker Maritime and Kværner Oil & Gas. On 3 April 2008, Aker Kværner was renamed Aker Solutions, partly due to the difficulty that most non-Norwegian people found in pronouncing "Kværner".The company was majority controlled by Aker ASA until 2007. Through a major ownership restructuring on 22 June 2007, Aker ASA completely exited its holding in Aker solutions, and transferred a 40% stake to Aker Holding - which in turn owned by Aker ASA , the Norwegian Ministry of Trade and Industry , SAAB and Investor AB .The company employs approximately 28,500 people in more than 30 countries. It has annual revenues of approximately NOK 44.9 billion. Wikipedia.


Based on the joint probability with regard to wind speed and its main direction, the current paper presents a practical and efficient approach for calculating wind induced fatigue of tubular structures, the effects of the wind direction, across wind and wind grid size on the high cycle fatigue of the structure are addressed. In each time step of the dynamic response calculation, the large deformation effects and the wind induced drag forces due to the updated structural deformations are taken into account. It is found that, the directional wind effects on the fatigue damage mainly depend on the orientation of the structure, the location and the support condition of the selected joints, and the relative probability of occurrence for the high winds speed in each direction, etc. Furthermore, the across wind components are proved to be a significant contributor on the fatigue damage and cannot be ignored. The fatigue damage is also found to be rather sensitive to the wind grid size for generating the wind fields. It is also concluded that vibration of each individual member interacts with the global dynamic response and the wind loading, and a fatigue check should therefore be against both individual member and global response. The wind fatigue calculation procedure presented in the current paper has the merit of reducing uncertainties without degrading a required safety level, this may lead to a positive economic impact with regard to construction and maintenance costs. It has been applied on quite a few industry and research projects and can be widely applied on the similar study of structures. © 2010 Elsevier Ltd.

Internal tree cap (ITC) adapted to be installed in the bore of a subsea well unit or to an internal tubular element of the same, comprising a locking element for releasably locking the internal tree cap to said subsea well unit or internal tubular element. The ITC further comprises a fluid channel extending through a fluid barrier between the lower and upper part of the internal tree cap, which fluid channel is blocked by a burst element adapted to break and open for fluid flow through the fluid channel when exposed to a predetermined pressure difference over the burst element. The invention also relates to an ITC running tool and a locking mechanism for supporting the ITC in the tool.
