Decommissioning Engineering
Elgenio provides engineering support for offshore decommissioning projects, from early studies and comparative assessments through detailed recovery engineering, mobilisation and offshore execution.
Our team has extensive experience supporting operators and service companies across the removal of offshore structures, subsea infrastructure, pipelines, umbilicals and associated equipment. We combine analysis, structural and project engineering with practical offshore experience to develop recovery solutions that are safe, proportionate and executable.
Decommissioning scopes often involve incomplete legacy information, uncertain structural condition, complex interfaces and significant offshore constraints. Our solution focussed approach considers these factors together, helping clients develop robust engineering strategies without introducing unnecessary complexity.
