A probabilistic model for estimating tunnel excavation time is learnt with data from past tunnel projects. The model is based on the Dynamic Bayesian Network technique. The model inputs are determined through an analysis of data from three tunnels built by means of the conventional tunneling method. The data motivate the development of a novel probability distribution to describe the excavation performance. In addition, the probability of construction failure events and the delay caused by such failures are estimated using databases available in the literature. The model is applied to a case study, in which it is demonstrated how observations from the tunnel construction process can be included to continuously update the prediction of excavation time.

“…As a result, the existing relevant standards, such as NORSOK and API, and classification rules are mostly limited to the provisions of general guidelines. No systematic investigation into the safety of FLNG has been undertaken to date, and the closest previous studies were on the risk of semi-submersible rigs and FPSOs (Jin, 2015;Bai, 2016;Sohn et al, 2013;Faber et al, 2012;Heredia-Zavoni et al, 2012). …”

This paper explores the probability of occurrence of accidents leading to vapour cloud explosion at one of the topside liquefaction modules of an FLNG. The worst possible scenario with the maximum tolerable probability is identified and the impact of the corresponding vapour cloud explosion is estimated. The strength of the structures supporting the neighbouring modules was examined using finite element analysis to determine if the accident has a potential of escalating to neighbouring modules. Potential Risk of Vapour Cloud Explosion in FLNG Liquefaction ModulesIt is found that the current levels of safety gaps between the liquefaction modules may be insufficient for the structural arrangement in place. It is thought that a new structural design using circular pipes as the structural elements instead of the I-beams may enhance the integrity of the top-side supporting structures against the impact of potential vapour cloud explosion. The effectiveness of the new structure is demonstrated by comparing it to the conventional supporting structure using I-beam members. This also implies that, by using pipe elements, the safety gaps can be reduced, thus making it possible to optimise the topside arrangement more easily.

“…It is based on the framework introduced by the Joint Committee on Structural Safety (JCSS), which aims at improving traditional approaches to quantitative risk assessment based on recent advances in system representation, consequence modeling, and definition of risk acceptance criteria [2]. The representation of a system in terms of its constituents, their exposure to potential hazards and their interrelations, the associated failure events, and the corresponding direct and indirect failure consequences has been discussed in [1]. In this approach, the functionality and performance of the system is provided by the interrelation and interaction of its constituents.…”
