“…Different safety indicators consider different periods of change, since some changes occur slower than others [27]. Hence, efforts are made to capture fast changing safety factors, to include them in real-time safety monitoring, e.g., by Knegtering and Pasman [27], or Vinnem et al [57].…”

The marine environment is vast, harsh, and challenging. Unanticipated faults and events might lead to loss of vessels, transported goods, collected scientific data, and business reputation. Hence, systems have to be in place that monitor the safety performance of operation and indicate if it drifts into an intolerable safety level. This article proposes a process for developing safety indicators for the operation of autonomous marine systems (AMS). The condition of safety barriers and resilience engineering form the basis for the development of safety indicators, synthesizing and further adjusting the dual assurance and the resilience based early warning indicator (REWI) approaches. The article locates the process for developing safety indicators in the system life cycle emphasizing a timely implementation of the safety indicators. The resulting safety indicators reflect safety in AMS operation and can assist in planning of operations, in daily operational decision-making, and identification of improvements. Operation of an autonomous underwater vehicle (AUV) exemplifies the process for developing safety indicators and their implementation. The case study shows that the proposed process leads to a comprehensive set of safety indicators. It is expected that application of the resulting safety indicators consequently will contribute to safer operation of current and future AMS.

Offshore platforms may potentially collide with vessels of various types, including visiting ships such as supply ships and passing ships. The most critical and relevant conditions, including the analysis and design approaches are introduced. Different ship types having different displacements and structural designs exert different vessel impact loads on impacted structures. This paper presents the findings of collision impact analyses of the side shell panel, bow and stern structures of Floating Production Storage Offloading (FPSO) platforms in case of impact, e.g. by a supply vessel or methanol tanker. As collision impact simulations continue to be conducted conservatively, the colliding positions of the striking vessel are presumed to be bow and stern only, with side force. In order to assess hull strength in collision events, non-linear FE simulations were performed by means of the MSC / DYTRAN tool, as these collision events result in more complex reactions. The degree of hull damage suffered by an FPSO vessel in different collision scenarios and at varying impact energy levels was determined in accordance with the NORSOK N-004 standard guidelines. Post-collision analyses were conducted to establish the structural integrity of the damaged hull after being exposed to environmental conditions for one year. The reduction of hull girder strength associated with the worst damage was evaluated and accounted for in the present study, providing no further damage occurs. Furthermore, the acceptance criteria for evaluation and corresponding consequences are calculated and discussed in detail. Finally, the findings from the present paper will help clarify the impact response of offshore structures and evaluation approaches and give valuable guidance for the design and operation of FPSO platforms.

“…A previous study shows that human error is the most complex and least understood factor in the failures of complex systems, accounting for as much as 60% to 80% of complex system failures (Sudano 1994). As an additional barrier function (Vinnem, Utne et al 2015), the new decision support system should aim at supporting infor mation to operators, reducing the potential for catastrophes induced or exacerbated by human errors. The complex HMI deter mines the importance of information sup port for ope ra tors' decision-making.…”

Automation and increasing complexity mean that operators have to handle data and alarms and emergent decisions under the pressure of unexpected and rapidly changing hazardous situations. Position loss during marine operations may lead to serious accidents, such as collision, loss of well integrity, etc. An online risk model aims at assisting operators in dynamic positioning operations to successfully recover the vessel's position in a good timing. The objective of this paper is to identify generic scenarios of position loss during operational phase and the information that is needed for successful recovery action. The results show that position loss normally involves of complex human machine interactions, generally in two patterns. Based on the findings, it has been recognized that risk model considering time aspect is of vital importance to develop an online risk model for DP operations.
