Maritime UK MASS CoP v2

n Concept of Operations (ConOps): To include details of the vessel’s role, operating area, operating profile,
environmental limits, maintenance and survey plans. The ConOps should also include any other information
required by the administration to enable a certifying officer to determine if appropriate standards have been
used. (Note: a good example of this is provided in the Lloyds Register Unmanned Marine Systems Code);
n The Design Standards, Codes or Rules used for the vessel;
n Periodic maintenance, trials and survey requirements necessary to demonstrate that the design intent is
maintained through life;
n A design justification as to why the particular standard is suitable for the vessel and intended use.
5.3.3 Typically, the design justification would be achieved by demonstrating that the performance requirements of the
structure, equipment or system under consideration is the same as would be required for an equivalent manned
vessel. (e.g. a 100m ship would require the same longitudinal stiffness and same propulsive power whether it is
manned or autonomous).
5.3.4 Where the MASS design departs from the equivalent manned standard the justification shall demonstrate that
either:
n The change is acceptable because the manned vessel requirement is redundant in the MASS (e.g. Removal
of crew habitability requirements or lifesaving equipment); or
n An alternative solution is required to maintain the same level of performance (e.g. Replacing a manual
firefighting system with automatic systems).
5.3.5 In either case the justification should demonstrate that the change does not result in an increased risk to other
vessels, third parties or the environment.
5.4 Structure
5.4.1 The structure should be designed, constructed and maintained with a level of integrity sufficient to enable the
MASS to be operated and maintained safely as and when required within its design or imposed limitations in all
RFOC.
5.4.2 Any penetrations in the structure of the MASS should not affect the watertight and weathertight boundaries.
