Transport Arrangements

– To create drawings, calculations & procedures for safe

movement of large, heavy Submarine & Ship components

in & around the shipyard.

– This includes specially designed transport cradles

– To fully understand BAE systems submarines transporter

capabilities

– To provide statement of requirements for ‘hired in’ sub-

contracted transport when the load exceeds BAE’s own

transporter capability.

Test Arrangements

–-Many items require a form of testing by law eg LOLER,

or MoD Contracts especially where lifting loads or

significant pressures are to be encountered.

–PED design and draw bespoke test arrangements,

procedures & detail drawings for the likes of adaptors,

beams, links etc. which are required to perform the tests.

– PED also have the capability to design & draw test rigs

when needed upon request.
