The document discusses the development and functionality of SIMA, a simulation tool for marine operations, designed to enhance training, quality assurance, and decision support through advanced modeling and analysis. SIMA features a user-friendly graphical interface and integrates with existing software, providing capabilities for feasibility evaluation and safety performance improvements. Launched in late 2012, SIMA aims to streamline marine operation simulations and facilitate effective communication across disciplines.

3. Background
In 2001 Norsk Hydro replaced flexible risers
at Njord
- Norsk Hydro has merged with Statoil
Damages occurred in adjacent risers during
replacement
Development of a simulator for
familiarization and training initiated

4. Motivation
Simulating boarding
Engineering
- Quality assurance
- Feasibility evaluation
- Distinguish the really challenging tasks
from the seemingly challenging tasks
Preparation for the actual operation
- Improve HSE performance
Simulating pipelaying
- Familiarization
- Cross – disciplinary communication
Decision support during actual
operation:
- Online monitoring
- Visibility
- What – if – analysis

5. Sima and DeepC
Sima – marine operations where DeepC – mooring and riser
Simo and Riflex is used analysis where Simo and Riflex is
used – includes code checking and
fatigue of risers
