New York, London, June 7, 2007: CD-adapco is pleased to announce the presentation of three technical papers as well as exhibiting at the OMAE 2007 conference and exhibition. Held from the 10th – 15th June 2007 in San Diego, California, the event aims to have “Industry, Academia and Government … Sailing Together!” and to discuss the latest technology in offshore mechanics. Along with Partners; Germanischer Lloyd, Jacobs Sverdrup, Northup Grumman Corp, and Daewoo Shipbuilding & Marine, CD-adapco has put together three technical papers on the use of 3D Computational Fluid Dynamics (CFD) covering wave loading on offshore platforms, sloshing in LNG tankers and maneuvering of submarines.

Wednesday, June 13th 9am – OMAE2007-29434 – Wave load and structural analysis of a jack-up platform in freak waves

Wind and wave loading on mobile rigs and offshore platforms has always been a critical design criterion. Add the destruction caused in the Gulf of Mexico by hurricane Katrina, and the requirement for predictive techniques to quantify accurately failure conditions and improve platform hurricane-resistance is clear. Three world-leading experts in 3D simulation for marine applications, CD-adapco’s Professor Peric and Germanischer Lloyd’s Ould el M octar and Thomas Schellin, have applied their expertise to simulating the wave loading and resulting structural stresses on a jack-up platform. The work compares the base shear, overturning moment, force distributions, stresses and deformations for different wave heights, and compares the CFD results to wave loads calculated using the Morrison formula. The result is an effect toolkit for assessing the structural integrity of a mobile jack-up platform in freak waves.

Wednesday, June 13th 11am – OMAE2007-29555 – Simulation of Sloshing in LNG Tanks

Shipping Liquid Natural Gas (LNG) in heavy seas presents a challenge to vessel designers and operators. The motion and forces on the vessel come from the sea waves, sloshing of LNG in tanks and wind loading. Understanding this highly coupled effect is of great importance, as serious and costly damage can be done to the tanks as well as affecting vessel stability. The authors set out a validated approach for simulating sloshing in LNG tanks and then apply it to a full-scale tanker, with partially filled tanks, in rough seas.

Wednesday, June 13th 2pm – OMAE2007-29516 – Submarine Maneuvering Simulations of ONR Body 1

Finally two, validated simulations – one consisting of a constant depth and heading run and the other of a horizontal overshoot maneuver – of a submarine maneuvering will be presented. This state-of-the-art work explicitly models the propeller and control surfaces, with the instantaneous position and body orientation determined by coupling the CFD solution to a six degree-of-freedom (6-DOF) equation.
