Foundations and Anchors

Foundation and anchoring systems must cope with heterogenous geological and geotechnical conditions, geohazards and harsh environmental conditions. Our design solutions cope with all of this whilst optimising CAPEX and remaining constructible. Our focus on the spatial understanding of complex soil and rock conditions, and the soil-structure interaction, complies with design codes but goes beyond these requirements to deliver tangible, enhanced value and benefit to our clients.

Working seamlessly with our structural engineering partners, we are able to offer a completely integrated and optimised design solution for all foundation types.

We provide detailed analysis and design for all types of offshore foundation and anchor structures in every conceivable geological and metocean environment:

Driven, vibrated and drilled/grouted piles

Gravity base

Suction caissons


Mudmats - non-skirted, skirted and sliding

Drag embedment, VLA's, SEPLA anchors

Novel and hybrid systems

Our design solutions are delivered in parallel with intensive soil and rock laboratory test management and ground model development to ensure that the project design has access to a high quality, integrated data suite which delivers a risk managed, optimised design. Depending on the project stage and survey data availability, a variety of design approaches can be delivered according to client needs for stage-gate decision making, CAPEX modelling, FID or for construction.

Wherever our clients are, and whatever conditions they may find at seabed, we have the foundation design solutions to realise their ambitions.

At Cathie, we deliver solutions for wherever offshore infrastructure interacts with the seabed. From basic analytical design according to established codes through to advanced and innovative computational methods using the most advanced finite element, finite difference and emergent methods in conjunction with machine learning. Designing with the express intent of lowering CAPEX, managing installation risk and improving reliability.
