Trans RINA, Vol 156, Part C1, Intl J Marine Design, Jan –Dec 2014
The same approach is used on the ceiling with KPM Sky Trac, and developed to be used with a range of 8mm lightweight sound proof and insulating boards, these can be covered with a wide array of colour laminates or fire retardant fabrics for styling purposes offering the interior designer freedom in styling.
5.4(b) Electrical and service routing
Access to electrical and service routes for most vessels has traditionally been problematic and hidden behind wall panel’s floors or roof voids behind paneling. In comparison Military ships and RNLI boats have visible
with the board precut and sealed to save further time in installation. The key to the speed of the installation is specially designed aluminum extruded profiles to cover all jointing types that may be required. The panels are supplied to the vessel numbered and precut to suit including window voids. Again there is limited or no trimming required for the fit as the panels and extrusion profiles are designed to allow a level of adjustment to cover gaps. As with the flooring and ceiling systems these panels can be removed quickly once installed.

electrical and service pipes for ease of repair. Yet this would not be practical or acceptable in commercial vessels for the purposes of safety and aesthetics. As such KPM marine developed a service skirt system that can be used in conjunction with wall boards. The principle behind the concept is called the “Rat Run”. This works on the principle that a rat should be able to get to any part of the vessel through these service arteries. There is also the ability to run services in the ceiling using aircraft style up lighters that not only accommodate the lights but also electrical cable. This feature is also useful for power drops from the ceiling to modular units and saves cables trailing on the floor which will be a safety hazard. This technique has been used in trains and planes for many years and gives the benefit of service routing being able to be undertaken with the whole vessel fitted out, and the obvious benefit of access for service or electrical additions.
5.4(c) Wall panels
Wall panels use the same principle of laminate, ply polyurethane foam composite which is very light at 3.5kk per square meter. Due to the heat and noise attenuation, the backing insulation can be significantly reduced in thickness from 50mm to 25 mm whilst saving weight. The insulation panels are also supplied

5.4(d) Modular interior Units. During specification the customer has a wide range of modular units that can be specified to suit the current use or future use. These light weight crash tested units are supplied in flat pack form and designed to pass through a 700mm door width. The modular units are designed to mount to a 310mm x 310mm square track pattern. As such all units can be rotated and moved as required. As with air planes there are no dividing walls needed, these walls fix to the floor track and ceiling track and can
be
moved or removed as desired. For vessels that have poor natural light levels the walls can be constructed from
shatter proof polycarbonate
materials in a vast array of colour’s , to pass light
through.
This feature can be seen giving protection to the galley and the changing room area,
thus allowing a light airy feel and the designer to address issues such as Headonomics.
