The petroleum industry is a technically challenging business with high investments, complex projects and operational structures. There are numerous companies and public offices involved in the exploitation of a new oil field, and there is a high degree of specialization among them. Even though standardization has been considered important in this industry for many years, there is still very lit...

Recent advances in hardware and software have generated a remarkable enhancement in the image quality and have broadened the obtainable information spectrum. Acoustic Surface Wave (ASW) is a naturally occurring phenomenon in surface of materials under load (force, temperature, etc). Spectral Analysis of Surface Wave (SASW) condition monitoring is related to the identification of certain vibrati...

An excess Gibbs free energy model is applied to in®estigate the influence of n-paraffin composition on the aging beha®ior of wax-oil gel deposits known to form in subsea petroleum transport pipelines. The aging of wax-oil gels occurs by a counterdiffusion process where wax molecules with carbon numbers greater than a critical carbon num( ) ber CCN diffuse into the gel matrix, and ®ice ®ersa. Mo...

Original scientific paper The multiplex (MUX) control system of subsea blowout preventer (BOP) plays a vital role in providing safe working conditions for the subsea drilling activities. According to the working states and critical failure modes of the MUX control system, this paper presents its stochastic Petri nets (SPN) model, taking into account the imperfect fault detection capacity. The n...

With the increased need of data sharing among multiple organizations like government organizations, financial corporations, medical hospitals and academic institutions, it is critical to ensure data integrity so that effective decisions can be made based on these data. An important component of any solution for assessing data integrity is represented by techniques and tools to evaluate the trus...

Aim: To explore the structures and processes for research ethics integrity among universities that are a part of European University Seas (SEA-EU) Alliance. Methods: Data from public websites or experts six Alliance: Cádiz (Spain), Western Brittany in Brest (France), Kiel (Germany), Gdańsk (Poland), Split (Croatia) Malta (Malta) were collected. We followed approach EC Mutual Learning Exercise o...

The objective of this work is to allow subsea teleop-erative tasks to be performed eeciently even when all communication between human operator and remote robot is via an acoustic link. This paper describes the integration of remote site cameras into the telepro-gramming system. Images from these cameras may be used for calibrating and maintaining the world model as well as for aiding the opera...
