The impact of this lightweight Interlocking Deck Floor System will allow operators the opportunity to extend the laydown areas on their existing assets and will provide more working space for the economic development of Marginal Fields Tony Zaccarini and Dr Patrick O’Brien
The Elevator Pitch Wavebeam technology will allow an operator to temporarily or permanently extend the physical laydown area of your existing assets. This would provide much needed additional space for Small Pools, Plug and Abandonment, Well Intervention campaigns, TAR applications and Fracking operations Individually, Wavebeam could also be used as a spreader beam to support heavy equipment on ageing assets and to support existing corroded beams prior to decommissioning
It would be far more cost effective to extend the physical area of existing assets rather than construct new facilities Existing Infrastructure OIL OIL Long Tiebacks Potential New Asset Existing Infrastructure Marginal Fields
“The Table Effect” Wavebeam could substantially increase the laydown areas on offshore assets and provide an effective solution for marginal field development in a cost effective and efficient manner The product impact to customers Develop existing hydrocarbon accumulations which are considered to be too marginal by fully utilising existing infrastructure to its maximum ability With insufficient capacity or remaining Operating life, Wavebeam could be deployed quickly to facilitate effective recovery of marginal fields
Circa 40% lighter Welds Than a standard steel beam 5 mm steel flange welded on top and bottom of wave and pipes 5 mm Internal wave welded along the entire length of beam Top of beam 5 mm thick x 80 mm diameter steel pipe supports welded to the inner bends along the entire length of the internal wave The dimensions of a standard Wavebeam would be 300 mm wide x 400 mm deep
Wavebeam 5mm for commercial applications Gun barrel Further development of standard hole configuration Wavebeam could include holes as an additional weight saving option Wavebeam Lite 3mm interior applications As the steel is thiner in Wavebeam Lite, it would be solid with no holes cut out along the wave
Steel pipes are welled to the inside curve of the wave and to the upper and lower flanges, adding further compression support to the steel beam. Note :- At the point where the pipes meet the wave, the thickness at the intersection increases from 5 mm to 10 mm. This further supports the loading capacity on the edges. As the wave and pipes alternately deviate from one side of the beam to the other, there is less likelihood of it buckling under extreme pressures.
After many months of search and development, a project undertaken by University of Strathclyde is about to be concluded The Key Measures Have produced various nonlinear finite element analysis of Wavebeam vs Industry Standard Beams and given a clear understanding of the main buckling modes of failures set against the background of many benchmarked academic research papers. This has provided a clear understanding of the critical Circa 40% lighter pitch and amplitude parameters which enables Wavebeam to Than a standard steel beam efficiently resist loads while remaining lightweight.
This illustration depicts the basic Wavebeam concept The Critical Design Factors in Wavebeam being a successful design include the thickness of steel which is used in the various elements including flanges, wave and cylinders Other factors such as the angle of wave deviation, circumference of cylinders and position and width of flanges relative to the depth of beam, all play a critical role in Wavebeam being an effective product A basic patent has been applied for and extensive research will ensure that the Critical Design Factors of this successful design will continue to be developed
An extensive Literature Review was carried out by the University of Strathclyde prior to the Wavebeam model being developed and tested

Wavebeam Interlocking Deck Floor System delivered by Articulated Transport By incorporating Wavebeams into modular sized interlocking deck floor box sections, 40ft (12.18m) x 8ft (2.44m) with the Sealed box same area as shipping containers, they could be transported, sections delivered and assembled with relative ease. We are currently manufactured from 5mm looking into the design of these deck floor sections with the plate steel to Advanced Forming Research Centre (AFRC) University of encapsulate Strathclyde, in association with Cadherent, a Structural Wavebeams Engineering Design company based in Aberdeen The deck floors of these sealed box section units would be supplied and fitted in sections. A top the deck floor would be completely covered in a lightweight composite grillage to protect the landing area from damage The Lightweight beam for Heavyweight applications

For customers, the value added will be the ability extract more oil by fully utilising existing assets, and the development of marginal fields at a fraction of the capex cost associated with building new offshore infrastructure The product impact and strategic fit for customers The majority of small pools are located within potential tieback and/or the extended reach of drilling distances to existing infrastructure. Take full advantage of what is already in place, as this is a radical new cost effective approach to marginal field development… …the alternative is a new asset
Wavebeam will bring substantial long term benefits to the offshore industry, not only for marginal fields, but also for other area such as TAR applications, Well Intervention, Fracking operations and Plug and Abandonment, and Decommissioning, Even if the lifespan of a lightweight Wavebeam platform only had a shelf life of 10 years before being replaced, it would still be a fraction of the cost of developing a new asset. The marginal fields you wish to develop, might not even last 10 years … …the alternative is a new asset
Two 16 x 16m Wavebeam platforms would have a greater physical laydown area than a standard supply vessel The average cost of a manned floating deck is around £50,000/day, the average cost of a supply vessel is around £20k/day
Substantially increase the physical laydown area of existing assets Make use of the free overhanging deck space suitable for many applications Marginal Fields Development TAR applications Decommissioning Well Intervention Fracking operations Plug and Abandonment
As an alternative, a permanent Wavebeam Interlocking Wavebeam Interlocking Deck Floor Deck Floor System System could be integrated into existing assets, or specifically incorporated into new build platforms As this offers the largest laydown space, more Wavebeams may need to be incorporated throughout the main structure
If platform topsides were made considerably lighter, the industry could substantially lower field life cost through improved decommissioning options as a result of reduced asset weight Use Wavebeam as deck spreader beams during decommissioning, and weight distribution on lightweight grillage applications or corroded deck areas Use Wavebeam for repairs on ageing assets with integrity issues, or for undertaking essential platform repairs where the structural integrity would be compromised
