“…There are many studies of human reliability in emergency situations. For example, Time Reliability Correlation (TRC) (Hannaman and Worledge, 1988) and Human Cognitive Reliability (HCR) (Dougherty and Fragola, 1988) in late 1980s, operator cognitive model and response action analysis under accident conditions (Parry 1995, Hollnagel 1996, and Smidts et al, 1997 in middle 1990s, and human reliability of emergency tasks in nuclear power plants (Pyy, 2000 andJung et al, 2001).…”

Collision between FPSO and shuttle tanker in tandem offloading operation has caused a growing concern in the North Sea. Several recent contact incidents between FPSO/FSU and shuttle tanker have clearly demonstrated a high likelihood of contact between vessels in tandem offloading. The large masses involved, i.e. high potential impact energy, make the collision risk large. Traditional ship/platform collision risk model may not be effective for tandem offloading operation. Further more in a broader sense, offshore quantitative risk analyses generally focus more on technical aspects, little on human aspects. This leads to a hardware-centered risk control approach, which may not be effective in the face of risks in complex marine operations.A collision risk modeling approach for FPSO and tanker offloading operation is presented in this paper. The collision frequency is modeled in the initiating stage and the recovery stage. In the initiating stage, this paper is focused on tanker powered forward movement (PFM) scenarios. The initiation of tanker PFM involves a complex man machine interaction. The risk model is set up which integrates technical events, human actions and their interaction in the initiating stage. This model guides us further to identify the two failure prone situations where man machine interaction happened and resulted in most collision incidents. The study to quantitatively analyze these failure prone situations and minimize their occurrence is presented in a companion paper OMAE 28101. In the recovery stage, this paper is focused on the tanker initiated recovery. Based on the proposed probabilistic model for the recovery stage, possible recovery actions are identified and the event development is modeled from initiation of tanker PFM to the final outcome, i.e. collision or near miss. The success of recovery is analyzed from the human action timing perspective. Based on qualitative and preliminary quantitative analyses, recommendations are made to reduce the failure of recovery in design and operation.

This paper analyzes the various selection methods of integrated template structures (ITSs) for use in the Arctic environment. First, an analysis of several actual projects is carried out, with the specific features of each described thoroughly. An important part of the work is devoted to the requirements of ITSs conceived in relevant NORSOK (Norsk Sokkels Konkuranseposisjon), International Organization for Standardization (ISO), and DNV (Det Norske Veritas) standards. The main elements of subsea production modules are examined in this work, along with their specific characteristics and components. Operation and installation of subsea modules in the Barents Sea are also analyzed in this paper. Four scenarios, with differing numbers of ITSs (two, three, four, and six) and differing quantities of well slots in each, are considered. For each scenario, a study of related marine operations (required for installation) is performed, and a program for installation-cost estimates is developed, resulting in the determination of an optimal design for the ITSs. Various parameters affecting the cost of subsea infrastructure are analyzed and studied from different perspectives (e.g., geometrical well-pattern systems, distance between drilling slots, drilling and construction costs). Risk analyses of the threats and consequences involved in the process are performed, and risk-assessment matrices and mitigation actions are established. As a result, a model for selecting an optimal ITS for the Arctic/Sub-Arctic region is created.

“…1.1 Risk analysis in the construction phases of projects Following the loss of the offshore concrete gravity platform Sleipner A during the construction phase of the project in 1986 [1], methods for risk analysis of the construction process were implemented in several Norwegian offshore facilities' construction projects [2]. Furthermore, risks related to marine operations were highlighted [3][4][5], and risk reduction measures were implemented. Regarding the development of the methodology, references were made to works by Bea [6,7].…”

This paper discusses the needs for risk analysis in industrial enterprises. Several major points of concern are raised. The fi rst topic is risk communication and the inclusion of feedback from involved parties. This also includes openness from top management concerning 'bad news' and its effect on project work. The second topic is the importance of thorough risk analytical work including hazard identifi cation, risk analysis, risk evaluation and subsequent management of risk-reducing measures. This paper suggests that risk analysis is an important tool for project management, highlighting the importance of paying early attention to issues arising in a project before they further escalate to more serious events.This paper brings up important topics of risk management and offers scenarios of how different elements can affect project management. We question whether industry, and especially the oil and gas industry, is moving in the right direction of conducting proper risk management and whether the risk analytical work is turning into a 'numbers game' and a pro forma activity.This paper focuses on the integration of risk management and project management, thereby risk analysis can be a powerful tool for project management, helping it to succeed in transferring the company into a high reliability organization. Keywords: Human and organizational factors in risk analysis, issue management, integration of risk analysis and project management, risk analysis of project construction phases, role of the risk analyst.
