Paper presented at the SNAME 26th Offshore Symposium, April 6–7, 2021
Paper Number: SNAME-TOS-2021-10
... combination of wind and solar power. Beyond this, the system has the potential to scale up to provide strategic levels of grid storage for longer averaging periods. This paper will present the technical design of an efficient and viable offshore compressed air energy system. electrical industrial...

Paper Number: SNAME-TOS-2020-001
... of vessels can be made with the difference in requirement for efficiency. In line icebreaking the number of vessels assisted in a unit of time is a key term. Different sets of realities encompass the different icebreaking duties. In some countries the number of icebreaking assistance cases annually is less...

Paper presented at the SNAME 25th Offshore Symposium, February 27, 2020
Paper Number: SNAME-TOS-2020-026
..., as our computational capabilities has grown, as has the demand for the number and complexity of problems that are simulated in a CFD study. Thus, hardware efficiencies have created a need for an increase in the number and type of models simulated and, in many cases, this has resulted in a net zero effect...

Paper presented at the SNAME 24th Offshore Symposium, February 20, 2019
Paper Number: SNAME-TOS-2019-021
... The marine and offshore industries face uncertainty in oil prices as well as concerns over climate change and energy transition. These are challenges but also opportunities as the industry moves from a culture seeking evolutionary concepts to a culture seeking efficiency through innovation...

Paper Number: SNAME-TOS-2017-016
... in the propeller case and the tip speed ratio (based on the inflow velocity far upstream) are kept constant. The procedure is tested for different cambers and thicknesses of the duct shape. The efficiency, inflow velocity and thrust on the blade and duct are obtained and analyzed. The influence of different...

Paper Number: SNAME-TOS-2017-029
... In particularly hostile and challenging deep water environments offshore, it is crucial to ensure asset management is effective, efficient and safe. Knowing the condition of assets is a pre-requisite for successful structural integrity assessments and to support risk based inspection strategies...

Paper Number: SNAME-TOS-2012-006
... was performed by the correlated analysis tools and established analysis procedures. The design efficiencies including payload, steel weight and production efficiencies of PC Semis for BPS and central GoM are addressed and discussed. Highly efficient PC Semi for BPS has been developed, validated and became...

... the effects of viscous drag through a drag-to-lift ratio. The model is then extended to include higher order terms in the case of inviscid flow. The maximum efficiencies for both models are presented as a function of the turbine's tip speed ratio and the number of blades. houston equation control...

... efficiently. For a specific and recent offshore renewable wind energy project, a comparison is made between different high modulus fiber materials, to which material is the most economically suitable. The application requires a high dynamic stiffness and low creep elongation, besides 25 year fatigue lifetime...
