  platform configurable to enable the life raft to   freely rotate around the chute column by means of a hoop/bearing assembly

Open grid lightweight support frame for storing the life raft in the stowed condition


Cable tensioning cans to hold the deployed system in the vertical position

Cantilever Skid Frame:


The cantilever skid frame is fabricated from 12” x 5” x ½” (305 mm x 125 mm x 12.7mm) box section A36 grade carbon steel.  The rear section of the cantilever skid frame is constructed in such a way that it can be bolted to the existing facility deck by the use of 1” diameter high tensile steel nuts and bolts. The rear section incorporates a checkered pattern floor decking, providing the main floor for the MAS-67 system.  The front section of the cantilever skid frame extends beyond the facility deck providing a clear drop to sea level.  The front section provides support to the structure housing the escape chute, raft and tensioning cans.

System Container Rear (aft) Section


The MAS-67 Blast Proof Containment system is designed to provide protection in situations where there is a possibility of explosion and gas leak.  The system is modular and is provided with a main container which is bolted to the sliding frame assembly. The containerized system provides protection in situations whereby explosion or radiated heat is present. The containment system protects the mechanical system making it available for evacuation in most emergency situations.


The main containment system is designed to be blast resistant rated to 5psi @ 200msec impulse duration. Blast testing was undertaken by the container manufacturer utilizing 1250Ib of high explosives ANFO at a standoff distance of 33.5m (110ft).


The AFT container specifications are as follows:


  Aft BP container size: 2.44m(L) x 2.44m(W) x 3.05m(H) - 8ft(L) x 8ft(W) x 10ft(H)

  Electrical System – Zone 1. Class1. Div1. ATEX Approved

  Emersion Rating for Electrical Components Min – IP66

  Internal Lighting System ATEX with three hour battery back-up

  ATEX approved pneumatic deployment/retrieval winch accumulator bank

  API 753 Compliant

  ASCE Medium Response 5/8/10/PSI

  Red or White exterior paint 3 coat epoxy with rubberized roof coating suitable for marine applications.

  Steel reinforced corrugated wall and roof panels

The MAS-67 Blast Proof Containment system is designed to provide protection in situations where there is a possibility of explosion and gas leak.  The system is modular and is provided with a main container which is bolted to the sliding frame assembly. The containerized system provides protection in situations whereby explosion or radiated heat is present. The containment system protects the mechanical system making it available for evacuation in most emergency situations.  The main containment system is designed to be blast resistant rated to 5psi @ 200msec impulse duration. Blast testing was undertaken by the container manufacturer utilizing 1250Ib of high explosives ANFO at a standoff distance of 33.5m (110ft).


The fwd container houses the life raft, escape chute, GRP storage frame, and the tensioning cans.  The trap door deployment handles are located at floor level as you enter the fwd section.  The life raft can be sized according to the facilities requirements; typical life raft sizing is 50, 100 and 150 man capacity.


The FWD container specifications are as follows:


FWD BP container size: 3.36m(L) x 2.44m(W) x 3.05m(H) - 11ft(L) x 8ft(W) x 10ft(H)

V450 Kevlar Variable Height Telescoping Chute


The system utilizes the ECS RSS-V450 Vertical Kevlar netted zig-zag style escape chute with stainless steel retaining bands. It is comprised a single layered netted Kevlar vertical escape chute with stainless steel bands sewn into each 1.22m (48”)section.  


The RSS Kevlar Escape chute provides heat flux protection of 650 degree, however the chute is netted and can still allow heat to penetrate through the tightly knitted holes, therefore Risk Safety Systems also supply an additional outer layer that is fully enclosed providing, true 650 degree heat protection and a melting point of 800 degrees C’. This outer layer is fitted to the maximum ballast level or highest recorded swell and is designed to provide maximum heat flux protection at deck levels.


Each chute section has a 1.22m (48”) Kevlar slide fitted. The slides are opposing on each 1.22m (48”) cell section and provide a zig zag effect.  Each 1.22m (48”) chute section has an access compartment for egress to the self-inflating boarding/debarkation raft and provides the required adjustable height evacuation point in cases of ballast condition or high wave action.  The V450 chute is designed to operate at varying heights for vessels with changes in ballast levels or locations prone to high wave sea conditions.


Three steel braided winch wires are connected to the winch located in the aft container at deck level and are attached at each 1.22m (48”) section of the chute column and terminated at the life raft breakaway plate. Upon deployment the chute, raft and tensioning cans are lowered to sea level using the pneumatic winch.


External Electro fiberglass Outer Sleeve


The V450 Kevlar netted escape chute is supplied with 650°C heat protection and melting point of 800°C. Although the micro-netted V450 Kevlar chute provides superior heat flux protection RSS have designed an additional outer sleeve that is fitted part of the way down the main V450 chute column to either air gap of maximum ballast based on vessel type.


The Electro-fiberglass outer sleeve has been used extensively for high rise buildings and offers superior totally enclosed heat flux protection with 650°C heat and flame resistance and melting point of 800°C whilst evacuees are in the upper part of the V450 chute column.  


High Capacity Life Raft with Breakaway Landing Platform


The life raft is a modified Zodiac SOLAS (A) pack raft size 100 person, verifying life-raft sizes are offered dependent upon client requirements.  The modifications allow the patented breakaway landing platform to which the chute and stabilization system fitted to be attached directly to the raft.  The breakaway landing platform is connected to the raft with pull pins that allows the raft once fully boarded to be detached from the breakaway landing platform thus being free to evacuate the hazardous area.  


The breakaway platform includes a patented slip ring counter rotating bearing arrangement allowing the raft to rotate freely in the X,Y & Z planes around the boarding platform under the influence of wind and current in evacuation conditions.  This is most desirable and a patented innovation as previous technology has only enabled the raft to move in the single vertical plane under the influence of wave action.

System Tensioning Cans

The tensioning cans are intended to sit in the water under the debarkation raft suspended at the end of the three main steel winch cables. Their function is to provide stability to the chute column and hold the chute in the vertical position. They designed in conformance with LSA Code 2010 to hold the chute column within 15o of vertical for a wind speed of Beaufort 6 with a significant wave height of 3m (10ft). Calculations are supplied to confirm correct tensioning cans weight/ mass to meet these requirements. Where client requirements vary the tensioning cans can be sized accordingly.

NEW Risk Safety Systems MAS-67 Fully Enclosed MES Gravity Winched - Escape Chute System


The MAS-67 offers the very latest in MES Marine Evacuation Technology.  The MAS-67 has been designed whereby there is no longer any need for additional external life rafts to be lowered to sea with a self-inflating boarding raft that requires evacuees to descend the chute and then have to cross board from the boarding raft to the main rafts awaiting recovery.  


The MAS-67 has one netted zig-zag chute and one 50/100 or 150 high capacity Survitec/ Zodiac or RFD modified raft that is integrated below the chute column, evacuees descend the chute and enter directly into the main raft, after all evacuees have descended the chute and entered the raft three pins are removed from the rafts rotating integrated boarding pad and the raft disconnects leaving the chute, rotating boarding pad and weighted cans in place.  


The MAS-67 is specifically designed for harsher weather environments such as the North Sea and removes the requirement for crossing boarding from the self-inflating boarding to the main rafts which can be hazardous in severe weather and wave conditions, the MAS-67 is fully recoverable using the Pneumatic winch and only requires that the main life raft be replaced
