Complex Analysis. Smart Solutions.

Tadek have provided heavy lift static and dynamic analysis, recovery, installation, and complex analysis for a range of ambitious projects. The team can support from shore or on site to react to weather and work collaboratively with the vessel and ops personnel to optimise operability as well as ensure safe completion.

Following numerous successful cable installation and repair projects globally, Tadek are experts at static and dynamic cable installation analysis. This includes 1st end, 2nd end, Free lay, A&R, Loadout and Pull-in operations, whilst cable repair scopes comprise omega bight, in-line joint and quadrant overboarding analysis in shallow and deep waters. Thousands of simulations are distilled into key operational recommendations, detailed lay tables and operability rosettes.

Many of the same skills and knowledge used in cable analysis are applied to pipelay analysis scopes. Tadek develop pipelay analysis and procedures for a large-scale O&G projects, and support operations onboard the vessels throughout the campaign. This includes, static, dynamic, fatigue and A&R analysis.

To provide automatic weather assessments to vessels throughout scope, Tadek have developed a tool to combine operability, weather forecast and real-time vessel information to increase uptime and aid operational decisions.

Experiences in both high value, high risk O&G umbilical design for permanent works, as well as floating MRE and FOW are combined within in-house tools to carry out dynamic system analysis for any cable, umbilical or riser system, resulting from vessel motion, waves and current.

Tadek have experience designing dynamic cable systems for FOW. Various configurations (e.g. lazy, pliant, steep wave, etc.) are assessed from platform to seabed, as well as IAC routing, to present operational, cost and risk analysis, as well as answering questions such as: how is fatigue life impacted by configuration selection?

The work includes cross-section design supported by an in-house software (PreCAB). PreCAB utilises well established equations and industry standards to deliver a cross section design sufficient and valid for FEED design and project cost estimation prior to more detailed cable manufacturer data.

Tadek offers specialized analysis and design services for cables and umbilicals with helical components within them, utilizing DNV Helica’s advanced methodologies. Our approach ensures accurate stress and fatigue assessment for each layer, factoring in critical elements such as friction interactions and dynamic loading conditions.

With experience across Flexible Risers, Umbilicals, and Power Cables, Tadek’s work is focused on providing precise insights that support informed design decisions and maintain structural integrity throughout the service life of the system.
