In modern marine construction, ensuring fire resistance, watertight integrity, and system flexibility is critical for safety and compliance. The MPACT Marine Pipe & Cable Transit System by Specified Technologies Inc. delivers a high-performance, modular solution designed specifically for sealing pipe and cable penetrations in fire-rated bulkheads and decks.
Whether for shipbuilding, offshore platforms, or marine retrofits, MPACT offers unmatched installation efficiency, adaptability, and long-term durability.
What is the MPACT System?
The MPACT system is an advanced marine firestop and sealing solution engineered to provide:
- Fire-rated protection (Class A-0 to A-60 and H-0 to H-120)
- Water and gas tightness
- Flexible configuration for complex penetrations
It combines three core components:
1. MFB-B Marine Filler Blanket
- Non-combustible, high-temperature resistant packing material
- Easy to cut and install in irregular openings
- Superior adhesion compared to traditional packing
2. MFS Marine Firestop Sealant
- Hybrid polymer technology with >99% solids
- Excellent resistance to water, UV, and ozone
- Prevents air, smoke, and gas leakage
- 25% movement capability for dynamic marine environments
3. MWS Marine Wrap Strip
- Intumescent wrap for combustible penetrants
- Expands 30–60 times under heat exposure
- Ideal for plastic pipes and insulated systems
Why MPACT is Ideal for Marine Applications
🚢 1. Certified Fire Protection
The system is tested to IMO FTP Code standards, ensuring compliance with international marine fire safety regulations.
💧 2. Water & Gas Tight Sealing
MPACT ensures complete sealing with a minimum 6 mm spacing, preventing:
- Water ingress
- Gas leakage
- Smoke transmission
⚙️ 3. Flexible for Complex Installations
Unlike rigid transit systems, MPACT adapts to:
- Irregular penetrations
- Mixed pipe and cable configurations
- Tight installation spaces
⏱️ 4. Fast Installation & Repair
- Simple 4-step installation process
- Minimal tools required
- Easy maintenance and repair without dismantling systems
🌱 5. Durable & Environmentally Safe
- Halogen-free formulation
- Long service life (>20 years tested aging performance)
- Resistant to harsh marine environments
Installation Overview
The MPACT system is designed for efficiency:
- Clean and prepare the opening
- Install filler blanket and wrap strip (if required)
- Apply firestop sealant
- Tool and finish surface
This streamlined approach significantly reduces installation time compared to traditional transit systems.
Applications in Marine Construction
MPACT is widely used in:
- Shipbuilding (cargo ships, tankers, naval vessels)
- Offshore oil & gas platforms
- Marine mechanical and electrical penetrations
- HVAC duct penetrations in vessels
- Retrofit and maintenance projects
