In addition, an audit of the manufacturing facility is undertaken with a focus on the quality control procedures in place for the product. The analysis was based on the extreme environmental conditions of the site where it has been suggested to install the system. Therefore, the main purpose of the paper is not to evaluate the wind turbine fluid dynamic response, ks to study the interaction between civil architecture and mechanical structure.

Edited by Katie Woodward Read the article online at: For full functionality of this site it is necessary to enable JavaScript. Ultimately, the dn of DNV OS C aims to create a unified consistent standard, covering the full lifecycle of an offshore concrete structure, that can be adopted by the industry. To address the current offshore concrete developments, DNV GL is now reviewing the Offshore Concrete Standard to provide updates and oa guidance, particularly for harsh locations.

This changed in when Eurocodes were adopted throughout Europe, including in Norway. This is believed to be due to the concrete degradation caused by cyclic varying pore water pressure and the pumping effect of water ingressing and exiting opening and c5502 cracks.

First of all, the 2 tourist-receptive structures Hotel and bar-restaurant around the wind tower have been designed and checked.

Historically, operators used the former Norwegian concrete standards for offshore structures. Concrete advantages In the polar extremes, concrete structures are durable and robust to resist collisions with icebergs and are resistant to abrasion from floating ice.


In particular, submerged concrete does not perform as well as above-water concrete under fatigue loading. Home Downstream Special reports 27 October Creating a complete code for offshore concrete structures.

Here are the instructions how to enable JavaScript in your web browser. In this way, an economical contribution to the sustainability of the wind farm is possible. When it comes to designing offshore concrete structures, important effects that need to be considered are, for example, the concrete fatigue performance under water, effects of water pressure in pores and cracks and principles for watertightness.

One of these materials is high-strength dmv. This is now changing with the renewed interest in robust concrete structures for the Arctic environment and for liquefied natural gas LNG storage. Unlike steel structures, concrete structures are built locally and therefore also promote the local economy.

Later, in order to study the effects on vertical cables fixed to the sea bottom, a detailed dn of the floating anchorage TLP Tension Leg Platform was carried out.

The approach defined in C ensures quality by considering all the aspects, from production to application, which are critical to the final in-place material offshore.

Fixed concrete structures can provide continuous production and fewer shutdowns as they can withstand harsher weather. Updated concrete standard Historically, operators used the former Norwegian concrete standards for offshore structures. In the polar extremes, concrete structures are durable and robust to resist collisions with icebergs and are resistant od abrasion from floating ice. Another interesting and unique feature of the updated DNV-OS-C is the systematics it provides for the qualification of new and innovative materials intended for offshore use.


DNV-OS-C502 – Detailed Design of Offshore Concrete Structures – Draft

Read the article online at: Concrete technology has quite literally been the backbone of the oil and gas industry for nearly 40 years, with concrete offshore structures enabling production in the most demanding operating environments. The purpose of the Eurocodes is to provide a harmonised set of design and construction rules that are applicable throughout Europe.

This content is available to members only. No other standard currently available to the industry covers the whole lifecycle of a concrete offshore structure and provides detailed design guidance. The standard has been developed on the basis of the experience DNV GL has gained over the years through its involvement in many offshore grouting projects.

TLP consists of a nearly fully submerged cylindrical platform, which supports a 5 MW wind turbine and is linked to the sea bottom by 3 ties which assure stability and limited tilting, even under the worst loads induced by wind and sea. A numerical model has been implemented and nonlinear dynamic analysis have been performed, investigating both the wind-structure and the wave-structure interaction.

Despite the fact that a number of concrete platforms are still in operation, particularly in hostile marine environments worldwide, there has been little development activity since the s. The area is well known for icebergs, which is why the operators have found concrete to be the most competitive c50.
