Determination of hydrate inhibitor injection rate for flowlines based on Monte Carlo method

Autor: Daejun Chang, Yeelyong Noh, Kwangpil Chang, Juneyoung Kim

Publikováno v: Journal of Loss Prevention in the Process Industries. 44:62-72

The present study proposes a new methodology that estimates the acceptable injection rate of a hydrate inhibitor considering the random failure and subsequent maintenance of the topside system followed by the cooldown of the flowlines and risers wher

Risk-based determination of design pressure of LNG fuel storage tanks based on dynamic process simulation combined with Monte Carlo method

Autor: Daejun Chang, Yeelyong Noh, Yutaek Seo, Kwangpil Chang

Publikováno v: Reliability Engineering & System Safety. 129:76-82

This study proposes a new methodology that combines dynamic process simulation (DPS) and Monte Carlo simulation (MCS) to determine the design pressure of fuel storage tanks on LNG-fueled ships. Because the pressure of such tanks varies with time, DPS

Methodology of life cycle cost with risk expenditure for offshore process at conceptual design stage

Autor: In-Beum Lee, Daejun Chang, Kwangpil Chang, Taejin Rhee, Kiil Nam

Publikováno v: Energy. 36:1554-1563

This study proposed a new LCC (life cycle cost) methodology with the risk expenditure taken into account for comparative evaluation of offshore process options at their conceptual design stage. The risk expenditure consisted of the failure risk expen

A study on availability and safety of new propulsion systems for LNG carriers

Autor: Sam-Heon Jeong, Kiil Nam, Daejun Chang, Taejin Rhee, Donghun Lee, Kwangpil Chang

Publikováno v: Reliability Engineering & System Safety. 93:1877-1885

This study investigated the availability and safety concerns of the conventional and prospective propulsion systems for LNG carriers: • dual-fuel steam turbine mechanical (DFSM) propulsion, • dual-fuel diesel electric (DFDE) propulsion, • dual-

Uncertainty Analysis for Target SIL Determination in the Offshore Industry

Autor: Sungteak Kim, Kwangpil Chang, Junkeon Ahn, Daejun Chang, Enrico Zio

Publikováno v: Journal of Loss Prevention in the Process Industries
Journal of Loss Prevention in the Process Industries, Elsevier, 2015, 34, pp.151-162. ⟨10.1016/j.jlp.2015.01.030⟩

The requirements on the design of SISs (Safety Instrumented Systems) based on SIL (Safety Integrity Level) have been developed continuously in the offshore industry. IEC 61508 and IEC 61511 illustrate various methodologies to determine the target SIL

The Impact of Heterogeneity in Purchase Timing and Price Responsiveness on Estimates of Sticker Shock Effects

Autor: Kwangpil Chang, Charles B. Weinberg, S. Siddarth

Publikováno v: Marketing Science. 18:178-192

The notion that individuals have an internal reference price against which they compare observed prices is well supported by several psychological theories. Empirically, several papers in the marketing literature, employing scanner panel data, have m

Flow Assurance Study for a Subsea Production System with a Large-Scale Seabed Storage

Autor: Inhwan Choi, Younseok Choi, Suyoul Park, Jakyung Kim, Yutaek Seo, Juneyoung Kim, Kwangpil Chang, Daejun Chang

Publikováno v: International Petroleum Technology Conference.

Abstract This study suggests a new concept of the subsea production system based on a large-scale seabed storage tank that stores the well fluid temporarily and later transfers it to the shuttle tanker through the riser. This concept was assessed to
