Aberdeen-based Aquatic Engineering & Construction has secured a ‘size-able’ contract with DeepOcean after an innovative way to make their customer’s project preparatory works more cost effective and time efficient.
In an effort to reduce mobilisation time and lifetime sea-fastening costs on the Edda Freya, a newly-commission offshore installation and construction vessel, the DeepOcean project team had decided on the inventive solution of integrating a track system into the deck.
The DeepOcean project scope called for a rental company to design and fabricate a new skidding system to interface with the Edda Freya’s integrated track system (pictured).
But the Aquatic Engineering and Technology team proffered an alternative solution, to modify one of their existing track system sliders. This slider technology principles and knowledge was already in-house since Aquatic had successfully produced a number of track-based solutions.
The added benefit of modifying an existing slider system, compatible with Aquatic’s largest reel drive systems, realised substantial cost efficiencies for DeepOcean – negating the need to hire separately or purchase a comparable reel drive system.
By making the decision to have a multi-reel solution erected (when required) in a fixed position on the vessel, DeepOcean has effectively saved hundreds of man-hours of draughting time in solution design and reworking back deck drawings, and many thousands of dollars in sea-fastening and mobilisation costs.
Aquatic design engineer Andrew Hasting, was given unprecedented access to the 150m vessel and host project team both in the UK and Norway.
He commented: “Innovation isn’t just about technological advancement; it is also about breaking down communication barriers all along the supply chain to deliver mutual benefit.”
Engineering team leader Chuks Wayemeru added: “The challenge throughout the subsea industry right now is to introduce efficiency though innovation.
“Our thought process when this opportunity presented itself was how can we help to reduce overall operating costs whilst still delivering to the tender? The answer was to produce what was asked for, and be bold with an original solution. We know that establishing relationships early in the life cycle of a ship build or installation operation is key and so, naturally, we are thrilled to have been a part of this forward-thinking DeepOcean project.”
The Edda Freya’s first operation mobilised last month from Kristiansund, Norway for Statoil’s Maria project. DeepOcean were awarded the SURF installation contract for Statoil’s Kristin and Heidrun platforms; the modification of the platforms was necessary for a tie-back from the Wintershall operated Maria-development. The offshore work included the installation of risers and dynamic umbilical and cable.
Aquatic were successful in winning the contract to supply equipment, a 500Te reel-drive system, including skidding system, and operational personnel for a 50-day hire.
