THE TORTOISE PROJECT

Objectif

The objective of the TORTOISE project is to investigate the requirements for subsea equipment protection, and to develop an innovative, low-cost energy absorbing system in line with these requirements. The design of such a system must also allow for ease of installation (including retrofit) and convenience of maintenance and workover of the protected equipment.
There is a need for subsea protection. A number of new concepts for protection systems have been evolued. Preference at present is on systems to absorb initial impact and then deflect. A theoretical analysis of objects free-falling through water has been developed and refined. Results compare well with other models but correlation with experiment is awaited. Initial analysis of underwater impact has proved difficult.
The initial phase of the TORTOISE project is directed towards obtaining sufficient information to determine logical design parameters for the protection system. This data-gathering phase will evaluate the risks and sources of damage, the types of installation to be protected, the behaviour of dropped objects underwater (experimental and theoretical analyses), impact mechanics underwater, etc., to provide a full understanding of design requirements. This work, combined with an initial evaluation of potential materials and structures and various conceptual design proposals, will enable targets and preferred routes for the subsequent phases of the project. Phase 2 will be directed towards the development of the preferred concept(s) and materials testing as required, as phase 3 is envisaged as the detailed, design construction and testing of the prototype protection system.
