Perry Slingsby Systems have recently initiated a new cable burial Research & Development project as part of an overall cable burial system development program. The project sets out to investigate the effect of water jetting on stiff to very stiff clay soils. To date, such soils have generally been beyond the capabilities of the industry’s existing cable burial and maintenance ROV fleet. However, Perry Slingsby Systems have found that it is becoming increasingly important for users to be able to extend the range of seafloor conditions in which burial can effectively take place. Perry Slingsby’s intention is that the project will eventually lead to the delivery of a new range of high capable jet burial equipment. This technical note describes the background and methodology to the first stage of the test program. It also details the selection of suitable soil test beds which were used to model stiff clay seafloor conditions. The test apparatus and procedures are also described and indications of the type of results obtained are given.
