DeepOcean provide project management, operational planning, engineering, mobilisation/ demobilisation, ROV vessel, offshore crew and have the overall responsibility of disposal as part of a decommissioning program.
Many old jacket type platforms will have to be removed more or less completely in the years to come – dependant on the regional and national requirements for the production block. Concrete gravity based platforms may be left upon closure of production, however typically steel and parts subsea in excess of one meter from the concrete must be removed. All parts must be brought ashore for considerate disposal.
It must be ensured that the recovered steel, risers, flexibles, umbilicals, or concrete are disposed onshore in a safe method. A contract with a disposal facility must be established, and their environmental standards will be evaluated together with the decommissioning customer.
Dangerous and hazardous chemicals and products will be considered and dealt with accordingly.
