... Ice conditions, low air temperatures, and remoteness are affecting the functionality and operations of offshore wind vessels. In addition, cold climates and ice have an impact on the economics of offshore wind installation and maintenance. Vessels without proper ice class have limited...

... This paper describes the design and third-party assurance process of an innovative feeder concept of the Wind Turbine Installation Vessel (WTIV) with lifting module. An efficient wind turbine installation process is vital to the future rapid development of offshore wind farms in the US. The main...

... of fixed and 264GW of floating by 2050 (Ref 1,2), up from only 56GW total now. The problem is the supply chain is not ready to support this. Currently there are only 17 wind turbine installation vessels capable of installing 10MW turbines, and only 3 capable of installing the newest 14 MW turbines...

... By 2050, global installed floating wind capacity is expected to reach 264 GW. Project sanction will require levelized cost of energy (LCOE) being significantly below current levels, but also to demonstrate that the life, property, and the environment are safeguarded. Most class societies were...

... is to perform an independent qualitative assessment of the current floating wind concepts. The assessment will focus on aspects related to technology readiness, design complexity and scalability, material selection, constructability, installation, operations, and maintenance. This paper provides the offshore...

... the mooring installation. With a very efficient holding capacity, and using the free-fall energy for its own installation, this technology is widely used in Brazil, by Petrobras. It is estimated that more than 2,000 torpedo piles were successfully installed in Brazil's shore. This Kind of Anchor is field...

... and, in some cases, can have unsatisfactory "trigger" reliability for subsea pipelines. The Residual Curvature Method (RCM) is a relatively new and efficient method for LB mitigation and has, to date, been utilized for shallow water pipelines installed by the Reel-lay method. When compared to other lateral...

... The quest for reliable and cost-effective solution of installing piles in deepwater led to the development of dynamically installed piles that embed themselves into the seabed through free-fall. Several variations of dynamically installed piles have been devised and successfully entered...

... Mooring systems of many long-term/permanent floating offshore installations (FOIs) are approaching the end of their original design life. Some FOI mooring systems are seeking life extension to support continued production/storage or planned tie-back. Worldwide, many offshore mooring systems have...

A brief history of dropped objects in the workplace as they relate to the historical development of safety systems will be discussed and the content of the ABS Guide for the Prevention of Dropped Objects on Offshore Units and Installations will be presented. Working...

... structures are integrated into the pontoon ring frames, which provide efficient local structural supports to carry the riser loads. The riser adaptor design is adjusted to the departure angle and azimuth angle for each specific riser. The design enables a safe and easy "drop in" installation of the riser...

... and more recently developed our own in line tensioner. The idea behind these developments has been to achieve a substantial reduction in deck weight, elimination of the space required and not least significant cost reduction. The focus has also been on reducing the overall installation time by simplifying...

... Classification Societies (CS) have accompanied Offshore Oil & Gas industry for decades to guarantee and enhance the safety of their installations through continuous improvement of design codes, standards, rules and methodologies. In today's environment, where the offshore industry business...

... A new semi type floating offshore wind turbine platform called Y-Wind is developed to support a 5MW wind turbine, considering various design aspects from engineering through to installation, which can reduce the CAPEX. The platform is designed to achieve the integration of the tower and rotor...

... supply vessel and/or Anchor Handling vessel, and self-erect with minimal human intervention. The columns and pontoon of the EDP Buoy are raised for construction and installation. When lowered, the structure behaves like a very stable deep draft semisubmersible. It is suitable for very harsh, but ice free...

... depth of 80m to produce power generated from wind and waves. The hybrid system is designed to produce a total of 10MW power from four wind turbines and twenty four wave energy converters (WECs). The platform design is based on industry standards and rules. The wind turbines are installed on four columns...
