A Consequence-Based Assessment Method/Software Model to Facilitate the Safe Location and Design of Occupied Buildings on or in Close Proximity to Process Facilities
| By DNV GL - Software
Ensuring the safe location and design of occupied buildings (permanent or temporary) is high on the agenda of key stakeholders – industry, regulators, and the workforce, not to mention members of the public who have a vested interest in the area. The significant amount of analytical work required in support of such an analysis represents a key barrier to conducting such studies in a detailed manner. It is often the case that a range of simplifications are utilised that can result in a less than realistic assessment.

This paper describes the implementation of two of the most widely used vapour cloud explosion (VCE) models, namely the TNO multi-energy (ME) and Baker-Strehlow-Tang (BST) into Phast, a general purpose onshore consequence analysis software package developed by DNV GL.

Sesam for Subsea
| By DNV GL - Software
In the oil and gas industry the term subsea relates to the underwater exploration, development and drilling of oil and gas fields. Subsea installations are used to develop reservoirs outside effective reach of existing platforms; they can be installed, designed and constructed in faster time than traditional platforms, making them an attractive substitute. And if surface facilities are available subsea is a much less expensive alternative, and can reduce the size of expensive platforms by moving some of the functionalities to the sea bed.

Subsea systems can range in complexity from a single satellite well connected to a fixed or floating facility to several wells connected to a central manifold tied to platforms or directly to an onshore installation.

This paper offers an introduction to subsea and showcases how Sesam offers the most complete and efficient tool to perform the design analysis of subsea structures.

Value Creation in the Enterprise Risk Management Process with Management Information Systems
| By DNV GL - Software
When working in a global business environment there is a great awareness of risk, yet most companies lack a complete picture of their enterprise risk portfolio. Stakeholders demand corporate accountability and transparency, and globalization calls for businesses to address risk quickly and demonstrate their risk performance almost real time. Corporations call for state-of-the-art technology and software support to respond to these requirements.

A Software Model for the Assessment of the Consequences of Explosions in Congested and Confined Spaces on Personnel, Buildings and Process Equipment
| By DNV GL - Software
Major accidents such as Buncefield, Texas City and, more recently, at the Amuay refinery in Punto Fijo Venezuela, all of which have resulted in large explosions, have focused attention on assessing the effects of Vapour Cloud Explosions (VCEs) on assets such as buildings and process equipment, as well as people. Ensuring the safe location and design of occupied buildings is high on the agenda of key stakeholders, particularly since two of the three accidents mentioned above resulted in multiple fatalities.

The Worldwide Offshore Accident Databank (WOAD)
| By DNV GL - Software
The Worldwide Offshore Accident Databank (WOAD) is a repository of information on accidents occurring in the offshore oil and gas industry. The initiative to start collecting this information began in the mid-1970s. Information on lessons learned serves as invaluable input to help industry understand and avoid accidents in the future. There are 2,288 fatalities currently recorded in WOAD among the recorded 6,451 accidents. This is a sobering thought and the driver for continuing with this worthwhile collection, which is something that has become much more than “data”.

Effectively Meeting the LNG Hazard Management Challenge
| By DNV GL - Software
Global use of Liquefied Natural Gas (LNG) has increased significantly in recent years and so has concern related to the proper management of the hazards associated with processing and transporting it. Such concerns are particularly heightened around land-based installations (or LNG carriers when berthed) due to the potential impact to local populations. Understanding how these hazards present themselves is central to their management.

Hydrodynamic Analysis of Offshore Structures
| By DNV GL - Software
This paper describes the role of a linear frequency domain analysis for offshore structures, and some of the important aspects that must be addressed when doing such an analysis. The two main challenges in this analysis, in addition to creating a good quality panel model, are: how to include the viscous effects, and how to handle the mooring system. Both of these will be discussed in some detail.

Risk Based Inspection Methodology for Atmospheric Storage Tanks
| By DNV GL - Software
Aboveground storage tanks (ASTs) are significant and common equipment items in the oil, chemical and transportation industry. Figure 1 shows two common types of tanks, one with a fixed roof and another one with a floating roof.

Sesam CAESES: Serious Play in Ship Design - Simulation-Driven Design for Naval Architects
| By DNV GL - Software
Simulation driven design is widely considered the key to innovative product development. While the integration of modeling and simulation is already well established in structural mechanics this is not yet the case with its fluid dynamic sibling. This is because Computational Fluid Dynamics is very demanding in terms of resources. Therefore, the intelligent modeling of functional shapes – like ship hull forms, propellers, pumps and turbines – is of paramount importance.

Naval architects have always been subjected to cope with non-planar shapes and have developed techniques that capture the essence of a complex geometry with as few defining elements as need be. These elements, normally called form parameters, are used to generate and vary a product. By closely coupling parametric modeling to simulation a synthesis model is created. Adding techniques of formal optimization, the process is further enhanced: It now provides the playground for serious work, complementing the human being’s intuition, experience and ingenuity.

SynerGEE GAS
| By DNV GL - Software
This paper discusses the flow characteristics of natural gas pipelines, the phenomenon of line pack and subsequent draft, and related operational issues. Both steady-state and unsteady-state (transient) flow characteristics are covered, and some typical techniques for dealing with power generation demands are discussed.

Taro: Powering Performance Forecasting for Power Plants
| By DNV GL - Software
Power interruptions, such as small shortages or complete power failures, have an impact on society; but industry also suffers considerably from power cuts. On average, the majority of power supply disruptions from transmission and distribution grids only endure for a few hours but complete shutdowns are not unusual in some parts of the world. Both types of disruption directly impact production companies but also critical infrastructure systems such as telecommunication networks, gas and water supply grids and hospitals. The consequences of these interruptions for industry are lower productivity, inability to deliver services, higher maintenance costs and unsafe operating conditions for equipment.
