Structural Engineering

With a strong track record in jacket structure and pile designs, Apollo’s structural team is available to deliver the full design package, from FEED studies through to detailed design deliverables.

Apollo teams have extensive experience of supporting floating systems including semisubs and monohull structures. Capabilities cover the environmental loading, accelerations, global and local structural assessment, allowing for coupled load response from the moorings, cables and turbines. Industry standard software packages are supported for analysis, with design to Inventor and Autocad applications.

Our established track record in the design of secondary steelwork for offshore platforms allows Apollo to deliver quality, cost-efficient designs such as boat landings, gangway landings, lift points, guides and bumpers, ladders and walkways.

Apollo structural engineers are well versed in the integration of third party equipment into fixed and floating structures. With advanced knowledge of construction best practice, design codes and the requirements of verification organisations, our structural engineers and designers will incorporate systems efficiently and effectively.

A central part of modern design practice is the use of finite element analysis for verification of global structures and subsystems. Apollo support industry leading software packages such as ANSYS, STAAD and FS2000 for plated, solid and truss structure design. FEA analyses are generated in support of LRFD and WSD studies, with linear-elastic, plastic, fatigue and seismic regimes.

Incidents do happen and it is important that sufficient residual integrity is available for foreseeable events, however unlikely. Apollo have performed a number of consequence analyses for vessel collisions, using plastic plate analysis to evaluate the large displacement response of the structure and to ensure that global collapse is not significant risk.

Our engineers work within technical review teams to evaluate the potential performance of designs in support of investment decisions. Using experience of a broad range of structural configurations, Apollo’s lead structural engineers bring multi-sector experience to the assessment of critical risk issues in the decision-making process.
