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
