Promat HPI in Marine applications

In ships, as in aircraft, the weight and the performance of insulation systems are crucially important. Whether for thermal protection or for fire protection, the very best performance/weight ratios are required.
The lightest marine passive fire protection (PFP)
It took the loss of the Titanic to focus attention on the modern concepts of safety at sea. In 1915 the first edition of the International Convention for the Safety of Life at Sea (SOLAS) was adopted. Fire at sea is possibly the most horrific of the potential dangers that can be encountered and fire safety was one of the issues addressed by SOLAS. The current issue of SOLAS dates from 1974 but has been updated on numerous occasions. Promat HPI is a leading manufacturer of passive fire protection panels and systems for marine applications. We offer an extensive range of products designed to meet the most stringent of requirements of 21st century fire protection legislation.

Marine exhausts by Promat HPI
Marine diesel engines can create exhaust gas temperatures of around 500 °C which are carried away to the atmosphere by the exhaust system. To keep engine rooms at tolerable temperature levels it is necessary to insulate the exhaust system in this area to reduce surface temperatures, ideally to around 50 °C. Available space is critical in this application and a Promat HPI system based on flexible microporous insulation is the obvious answer.

Promat HPI solutions for cruise ships
Promat have a long history in the provision of marine components including bulkheads, internal partitions, ceilings and floors, and thermal and acoustic insulation.

Marine insulation – the challenges
Size, weight, and performance are all critical in design for aviation applications. With these goals in mind, any insulation used must meet the following design criteria:

  • Best performance – lowest thermal conductivity
  • High temperature capability for PFP
  • Smallest volume – lightest weight
  • Not affected by thermal shock
  • Dimensionally stable at all temperatures. No shrinkage or other deterioration with time
  • Resistant to damage by vibration

Application solutions

Marine passive fire protection (PFP)

Modern lightweight fire protection really started in 1997 when the very first Microtherm® PFP system was fitted to the walls and ceiling on the vehicle deck of a Fincantieri Super Sea Cat fast ferry. The weight saving over the conventional mineral wool insulation that had been previously specified was in excess of 20 tonnes on this vessel. The improvement in cruise economy and potential top speed were equally impressive.

PROMAGUARD® is a flexible high temperature insulation panel created primarily for passive fire protection (PFP) systems for marine applications, also rail, road, and aerospace applications. The Microtherm® low density microporous insulation core is covered in a glass cloth outer layer to create a lightweight insulation panel. This is then overstitched through with a specially selected thread on a broad grid pattern to create a robust, lightweight, flexible panel that can be easily formed and fitted around complex shapes and structures. PROMAGUARD® is mounted onto pins for lightweight passive fire protection systems that maintain integrity during long duration fire exposure for bulkheads and for the underside of decks and floors.

A Promat HPI PFP system for a marine application is the lightest system currently available.
Marine defense

Microtherm® high temperature thermal insulation systems offer are the lightest and most compact protection against excessive heat and fire in marine applications around the world. They are used in areas where weight saving is of paramount importance. The insulation is certified non-combustible and the outer covering materials certified for zero spread of flame.

Microtherm® is used for heat shields, exhausts, and passive fire protection (PFP) on warships and hanger doors etc. Promat HPI PFP systems for composites are perfect lightweight solutions for stealth technology warships. The extensive range of Promat HPI insulation products available are a big factor in aiding design wherever compact thermal protection is necessary.
Insulation protection to voyage data recorders

Voyage Data recorders (VDRs) are similar to the aviation "black box" recorder where if a vessel is involved in an accident or sinks, data can be retrieved to reconstruct the last 12 hours of the vessels voyage. This allows the marine community to clearly understand the reason for the accident, however catastrophic, and put in preventative measures to increase future marine safety.

The Simplified Voyage Data Recorder or S-VDR is a system that the International Maritime Organisation (IMO) has mandated for carriage on the majority of large sea going vessels.

Promat HPI technology allows the VDR to withstand the fire and explosion risk that a vessel may encounter during a catastrophic calamity at sea.
