Mooring Solutions

Experts in mooring geotechnical design, Ryder adopt a fully holistic approach to ensure all project design variables and requirements are satisfied.

  • Use of a proprietary tool developed in-house to assist with determining the optimum foundation solution, considering a number of variables, such as field layout, installation constraints, environmental impact, decommissioning, HSE, sustainability, cost, and foundation type.
  • Consideration given to a variety of mooring solutions, e.g. suction installed piles, driven tubular piles, drag anchors, and suction installed plate anchors.
  • Preliminary and detailed geotechnical design and optimisation to required regulatory specifications, e.g. ABS, API, ISO, and DNV.
  • Lateral capacity assessed using Ensoft LPILE calculating deflection, shear, bending moment, and the soil response with respect to depth in non‐linear soils.
  • Inverse chain catenary assessment to establish the loads at the padeye carried out using proprietary inhouse software following industry recognised guidance.
  • Penetration resistance of suction installed piles, with calculation of critical underpressures and overpressures for installation and extraction.
  • Pile driving assessment considering up to date recommendations on calculation of resistance, and carried out using GRL WEAP, including pile stresses and accelerations.
  • Drag anchor holding capacity, potential drag distances and penetration depths.
  • Recommendations and design of installation support requirements, e.g. pile driving support frames.
  • Chain pull in and pretensioning requirements during installation
