This first fit pyrolysis plant installation is part of the
environmental measures being implemented on Ocean,
and is central to the MoD’s waste management strategy.
The same technology is to be used on the future aircraft
carrier (CVF). A further environmental measure is the
application of a newly developed environmentally-
friendly antifouling coating to be used on the hull,
which will prevent marine growth and hence reduce fuel
The large and complex Ocean DP2 programme also
has a focus on improving accommodation and further
equipping the ship for her worldwide role. In addition
to the significant maintenance and defect rectification
element, the work package includes more than 40
alterations and additions (A&As).
HMs Ocean should be back in service – with her new
pyrolysis waste disposal system, seen here being
installed – by the end of 2008.
