Abstract: |
Offshore activity is developing and
resulting in new demanding high-risk operations. Operation complexity increases
with factors like heavier loads, subsea installations, and arctic waters;
operational planning requirements increase as well. Demanding offshore
operations are usually planned in detail, where plans may fill several binders,
leading to information overload for the ship crews. Extracting critical information
becomes a challenge. In some cases, only a basic plan exists, and aborted
operations are quite frequent, also where a contingency plan could have
enabled recovery. This results in substantial extra costs for the operating
company. The industry is facing two
key challenges concerning operational planning. One is to develop good
planning frameworks, to enable plans with robust risk management and control.
This calls for modelling techniques for operational
plans. Another is optimal presentation of the plan for each individual crew member, both in the briefing and in the execution
phase of the operation. It is important that every individual has easy access
to the most relevant and safety critical information for his given role and
the current situation, in an easily accessible and comprehensible format.
This calls for operational software to support situation-awareness. A fundamental
necessity to achieve this is modelling techniques which support a joint understanding of the
operation between operational planners, ship crew, software engineers, and
ultimately the support software. In this paper we show how to translate
hierarchical task analysis (HTA) models into software models and then into situation-aware
software prototypes |
