Evaluation of ballast failures during operations of semi-submersible rigs
(Peer reviewed; Journal article, 2019)Risk analysis/assessment is one of the challenges encountered during operations of offshore units on the Norwegian Continental Shelf (NCS). In recent years, the Petroleum Safety Authority (PSA) has focused on hazards ... -
An evaluation of different RANS turbulence models for simulating breaking waves past a vertical cylinder
(Peer reviewed; Journal article, 2021)The purpose of the present study is to evaluate the performance of different turbulence models for predicting the interaction between breaking waves and a vertical cylinder based on the volume of fluid (VOF) method. Six ... -
An evaluation of key challenges of CO2 transportation with a novel Subsea Shuttle Tanker
(Peer reviewed; Journal article, 2021)Recently, a novel Subsea Shuttle Tanker (SST) concept has been proposed to transport carbon dioxide (CO2) from ports to offshore oil and gas fields for either permanent storage or enhanced oil recovery (EOR). SST is a large ... -
Evolution of Scientific Management Towards Performance Measurement and Managing Systems for Sustainable Performance in Industrial Assets : Philosophical Point of View
(Journal article, 2009-01)Even though remarkable progress has been made over recent years in the design of performance measurement frameworks and systems, many companies are still primarily relying on traditional financial performance measures. ... -
