Green Technologies for Marine, Offshore, Oil & Gas Engineering

Computational Fluid Dynamics (CFD) is used to evaluate the scalability of the Semb-Eco LUV Ultraviolet (UV) Ballast Water Treatment System (BWTS) product series in terms of the Reduction Equivalent Dose (RED), a key performance parameter. The performance of base UV reactors has been verified following the IMO G8 guidelines. In addition, research and development on next generation cavitation/ultrasound (US) Ballast Water Management System is conducted. This BWTS does not require any chemical agent and it may eliminate the need for filters. 

IHPC’s modelling and simulation capabilities include:

• Flow of water
• UV radiation transportation
• Cavitation
• Compressibility
• Turbulence
• Micro-organism particle trajectories
• Estimation UV dose
• Prediction of Reduction Equivalent Dose (RED) 

Asia dominates LNG market and Singapore is in a strategic position to tap on these opportunities. Singapore is LNG bunkering ready and pushing LNG as shipping’s fuel for the next decades, readying a swathe of incentives for shipping companies that decide to use gas instead of classic marine fuel. The Maritime Port Authority (MPA) of Singapore expects the first of its two LNG bunker tankers to facilitate ship-to-ship LNG bunkering for ocean going vessels from the second half of 2020 onwards. 

To enhance further wide adoption of LNG gas as cleaner solution, regulatory framework and acceptable safety protocols are required. One of the key challenges is that the current regulation for LNG bunkering procedure is conservative. Existing commercial simulators are not ideal to simulate LNG bunkering leakage in complex geometries. 

IHPC’s modelling and simulation capabilities include:

• Gas dispersion model for simulations of LNG leaks as a high fidelity CFD-based quantitative risk assessment (Fig 1). The tool is capable of considering transient effects of a typical jet release, complex geometries and gas dispersion physics.
