VIDEO: Prize Winning Stinger Handling System Improves Vessel Design and Pipe-Laying

ULSTEIN is currently customizing their innovative Chain type Stinger Handling system concept for three different companies on three different continents. The compact system improves both the vessel design and pipe-lay operations, and as acknowledgment on April 16th 2013, the equipment has won the bi-annual IRO Innovation Prize. The participants casted their votes for the 4 nominees, and Ulstein Idea Equipment Solutions came out as winner.

Two distinct developments can be observed in today’s offshore construction market: Firstly, exploration and production in deeper waters will continue to push boundaries of existing technologies, and innovative solutions will be required to enable construction at increased water depths. Secondly, the operators are increasingly striving to optimize of the utilisation of existing or smaller assets with smart equipment to perform at better cost.

Deepwater infield pipelines are forecast to grow at a yearly pace more than 15% between 2012 and 2017. Pipelines are typically installed by using techniques called J-Lay or S-lay. Traditionally S-lay was used in shallower waters and J-lay for deeper waters. However, since S-lay provides some distinct advantage over J-lay in relation to the optimisation of the pipe-joining process, the market demanded to further develop S-lay equipment to install pipelines at deeper waters.

The deeper waters require the stinger and its handling system to be capable to operate at higher loads. Most offshore construction vessels, so called derrick lay vessels, used for the installation of sub-sea pipelines have both pipe-lay and heavy-lift functionalities.

Traditionally the stinger handling system comprises winches with wires and sheaves, which, by the increasing load is reaching its practical limits in relation to the available deck space with the presence of the offshore crane. Another disadvantage and operational cost often forgotten is that wires need to be frequently exchanged, imposing both cost and downtime for (de-)reeving. For most heavy lift operations, the stinger will be removed and to avoid time demanding (de-)reeving of the cables typically an A-frame is added to the Stinger Handling configuration. Aside from the investment for such frame, an A-frame imposes an obstruction to the so called firing line for objects that may need to be supported from the vessel into the water.

The market demand and opportunities for operational improvements of existing solutions led to the development of the Chain type Stinger Handling System by Ulstein Idea Equipment Solutions. The system is very compact and characterised further by its small footprint, leaving space for most lifting operations. The system comprises hydraulic driven chain pull units, using only proven technologies and components. For large heavy lift operations the units, including the chain, can be quickly removed by simply removing some pin connections and some connections at the manifold. By its nature this system does not contain costly consumables nor does it require a heavy and costly A-frame, optimising the investment of the equipment. As the main pulling system comprises large capacity cylinders, the system can be easily upgraded with a functionality to avoid slack chain due to stinger uplift, using components already present.

SNS2017 – The Southern North Sea Conference & Exhibition

EEEGR’s flagship Southern North Sea conference is the most important event for the energy sector in the East of England. Taking place over two days at the Norfolk Showground Arena in Norwich, SNS2017 will be the largest conference and exhibition EEEGR has ever delivered attracting upwards of 700 delegates from across the industry and supply chain.

Key industry players will gather at this event to discuss and debate issues, network to make new business contacts and re-establish relationships with existing clients.

Why should you attend?

  • Generate fresh leads and meet new contacts in a time and cost-efficient way.
  • Showcase your expertise and share your insights to impress your clients.
  • Meet senior-level delegates looking to learn and seek out new partners.
  • Account manage and liaise with your current clients attending – or bring them along yourself as an account management tool.
  • Months of intensive marketing and advertising to relevant markets ensuring a high level of attendance.
  • Numerous on the day and follow up advertising opportunities available to enhance your positioning.
  • Stay one step ahead of your competitors by being seen and visibly present at the event.
  • Develop your brand and status within industry by being billed as an event sponsor.

SNS2017 – 2 March

Day two of the conference is dedicated to ScottishPower Renewables Supply Chain Event for the East Anglia ONE Wind Farm Project.

ScottishPower Renewables is in the process of finalising its major contracts for the East Anglia One project, and is delighted to announce that these contractors will be attending the ScottishPower Renewables Supply Chain Event at the Norfolk Showground Arena on 2 March 2017.

Occupying the second day of EEEGR’s SNS2017 Conference and Exhibition, the ScottishPower Renewables Supply Chain Event will allow their contractors to engage with businesses and stakeholders in the East of England and further afield as quickly as possible to outline the skills they require and the business opportunities to be created by the project.

Information will be provided on the current status of the project by ScottishPower Renewables Managing Director, Jonathan Cole, and East Anglia One Project Director, Charlie Jordan. There’ll also be information on the scope of works to be carried out, explanations of how to get involved and the opportunity to meet representatives from Seaway Heavy Lifting, Navantia, Lamprell, Harland & Wolff, Roadbridge, Van Oord, Prysmian, VBMS, Nexans, DeepOcean, Peel Ports Great Yarmouth, Siemens and ABPorts.

Up to seven additional suppliers will also be attending, to be confirmed shortly. Opportunities will range from civil and electrical contractors, vessel and ports support, to technicians and logistics.

ScottishPower Renewables is starting construction this year, with the first turbines to be installed by 2019 and the project fully operational during 2020.

Full-access pass holders will be able to take full advantage of the presentations whilst there are also free exhibition-only passes which will give holders the opportunity to network with representatives from these suppliers at their stands. Delegates MUST register prior to the event to be allowed admission. Upgrades of exhibition-only passes may be permissible on payment of the appropriate fee.
