Rob Duffin presented a number of issues ranging from the significance of SPS in the transformation of FPSO’s which includes reduction of operational costs, life extensions and easier repair of the current station assets without disruption or operational effects. Another issue presented in the meeting was the compliance of the new technology to anti-piracy measures. I will report each of the issues separately as presented by Rob. The Director of the Institution of Civil Engineers introduced the presenter.
Sandwich Plate System (SPS) overview Rob described the SPS is a structural complex consisting of two metal plates joined together using a polyurethane elastomer laminate a definition he got from Lehmann and Egge book published in 2009. Rob asserted that SPS is easier and tougher compared to hardened steel plate and is not as heavy to use as the strengthened concrete. SPS has found various applications in several areas such as structural flooring, pitch and field terraces, fixing and construction of ships of ships, and construction of bridges.
SPS the Global Perspective Rob derived the global perspective of SPS technology from Kennedy and Ferro’s book published in 2007. Rob reported that all the Global stakeholders have acknowledged SPS as beneficial in the construction industry particularly concerning enhancing performance, sustainability and safety. In the maritime constructions, SPS has replaced the usually hardened steel used in making components such as hulls and bulkheads of ship. SPS reduces the stiffening problem and makes the components less prone to rust and fatigue.
SPS is used in the construction of bridge supports and structure floors in replacement of the conventional strengthened concrete. SPS eliminates the problems of fatigue and rust associated with the use of strengthened concrete and steel. SPS place are easier to design and customize to the required dimensions. Some of the benefits of SPS plates include reduction of stiffness in structures, ease of application and enhancement of designs in deeper-water construction. FPSO conversions –compact Double Hull Just as mentioned by McDermotte in his article Tanker Structural Analysis for Minor Collisions published in the Journal SNAME Vol.
102Technical Note FPSO P-57, typical SPS Overlays in the FPSO conversions entail the cleaning of the existing plate, fusing solid steel perimeter bars to create boundary functions. Rob pointed out that some of the advantages of the SPS Overlay include quicker repair schedules, reduced labor and minimized downtime. The overlay provides permanent upgrading at minimized repair expenses, lessened operating expenses and enhanced revenue potential. Offshore Life Extension According to Rob, McDermott in his article also emphasized the significance of offshore life extensions.
SPS Overlay is a quicker and efficient method of reinstating and intensifying offshore crafts and structures. The Overlay thus strengthens the structures and prolongs their lifespan by offering permanent solutions to the previous short-lifespan projects. SPS Overlay allows for construction of high quality vertical and horizontal supports that possess strong impact resistance, lessened fatigue and controlled crack propagation. An advantage with the SPS Overlay application is that is employs the pre-existing or damaged plating to construct parts of the steel laminate panel.
This is a cost-saving process while still increasing the
