This document is the first annual report on dissemination and communication activities regarding DTOceanPlus project.

This document identify and analyse different damage initiation mechanisms and their propagation through the dynamic cable. It will consist on building failure scenarios from initiation, propagation and final failure steps, and put the degradation mechanisms in relation with the nature of stresses that has been at the origin of the failure.

A coherent set of requirements have been developed for the DTOceanPlus suite of design tools based on analysis of gaps between tools in mature industries and those in the ocean energy industry, learning from the original DTOcean project, and the stakeholder expectations identified in the user consultation exercise. The technical requirements in this document are translated from the general requirements for the overall suite of tools, and specific requirements (functional, operational, user, interfacing, and data) for the Stage Gate design tool that will be developed as part of this project.

Deliverable D4.2 “Stage Gate Tools – alpha version” of the DTOceanPlus project includes the details of the Stage Gate Design Tool, and it represents the result of the work developed during task T4.2 of the project. This tool is an application of a stage gate process which is used in research and industry to provide structure to the technology development process. This approach supports the R&D pathway towards producing reliable and cost-effective ocean energy sub-systems, devices and arrays.

The most commonly used procedure for prediction of the behaviour of laterally loaded piles is the P–y curve formulation, which gives a simple but efficient framework to predict the response of the pile. This framework is limited to a single direction of loading, while there are several situations in which a pile is subjected to lateral loads with varying direction, as for example in the case of wind or wave loads. Here an extended framework for P–y curve modelling is presented, in which several springs are considered around the pile perimeter at each depth. The advantage of this framework is that it remains as simple and practical as the original P–y curve method and does not need any further information or parameters. A procedure is proposed for the extension of a given unidirectional model to the corresponding multi-directional one. The effects of multi-directional loading are discussed based on the simulation results. With a change in loading direction, misalignment between load direction and total displacement occurs. In addition, this quite simple model enables deduction of the profile of irreversible soil displacements around the pile at various depths.
