Offshore decisions

It is important to both quantify these factors carefully when making the offshoring decision and track them over time. As Table 6-2 indicates, unit cost reduction from low labor and... 

Offshore oil platforms are highly automated, requiring little direct operator input to maintain production. In the event of a serious abnormality such as a fire or a gas escape, the control room worker is required to make decisions as to whether to depressurize one or more systems and which systems to blowdown. Other workers have the facility to depressurize some systems at a local control room. 

The major finding of the study was that the manual blowdown philosophy, particularly with respect to gas situations, was not clearly defined. This was most apparent in the offshore attitudes and perceptions regarding the importance of blowdown as a safety system. No decision criteria specifying when blowdown should or should not be activated were provided for the support of control room staff. Blowdown was essentially left to the discretion of the workers. Consequently, the offshore interpretation of this vagueness and ambivalence amounted to a perceived low priority of blowdown. It was concluded that this percephon would probably lead to a significant delay in blowdown or possibly the omission of blowdown when it was actually required. 

There are typically a few major contributors to the cost savings from the business side, such as consolidated purchasing, inventory management, supply chain integration, offshoring etc. Look for those to justify the harmonization decision - the rest is windfall profit . 

In this example we consider the design, planning, and scheduling of an offshore oilfield infrastructure over a planning horizon of 6 years divided into 24 quarterly periods where decisions need to be made (Van den Heever and Grossmann, 2000). The infrastructure... 

Under general administrative law, a licence may be revoked if the licensee commits a major breach of conditions upon which the licence is based. The violated condition need not be express for a breach to have this effect, but it is of course a prerequisite that the rule violated can be fairly and objectively attributed to the licence. In relation to safety aspects, this implies that even if the compliance with safety requirements has not specifically been made a condition for an approval, licence, exemption or other type of individual decision, the non-compliance with safety requirements may result in the revocation of the beneficial administrative decision. In this way, general principles and rules of administrative law supplements shortcomings that may exist in the rules on revocation that are found in the safety legislation. Similarly, the Criminal Code is applied to the offshore petroleum activities by general reference, which implies that the specific criminal sanctions contained in the safety legislation are supplemented by general rules.

A survey has been made of the regulatory and industry requirements in the Oil and Gas industry for defining Risk Acceptance Criteria (RAC). The focus has been on Norwegian and UK offshore oil industry. RAC may be quahtative or quantitative, and are known variously in the Oil and Gas industry as, e.g., risk criteria , decision criteria , screening criteria , tolerability criteria . 

The decision processes are heavily affected by the implementation of lO. Decisions shall be taken by teams rather than by individuals and these teams may he distributed on different locations such as for example onshore and offshore. More planning activities from onshore are regarded as positive by the interviewees and the enhanced cooperation between onshore and offshore is positively received as well. 

Shared situational awareness is a key factor in most safe work processes (Nsesje et al. 2009). HSE is affected by daily decision-making and task solving processes. In addition to cooperation between management and technical teams, work processes also include cooperation between onshore/ offshore and interaction among different disciplines.
