Davit Launched Escape Chute

International Safety & Supply is a global Supplier of custom designed escape chute
manufactured by Survitec/Risk Safety Systems located in Houston, Texas USA.
Escaping from danger or fire has never been this easy
Escape chutes provide a means of emergency exit that permits rapid, mass evacuation
from offshore installations during life threatening emergencies. It is uniquely designed
to provide a relatively safe and quick method of vertical escape and is always accessible
and ready for use. it provides a unique solution for vertical escape in sometimes
difficult conditions during an emergency evacuation.
A simple Escape System
The construction of the chute helps to protect the evacuees from heat and fire and
is used to deliver evacuees to safety with very little training. This is sometimes
difficult or impossible using traditional rescue equipment.
Three way Protection—The escape chute consists of three layers. The outer layer is
of a material that will not ignite. The middle layer helps to regulate the speed
of decent, inner layer reduces friction.
Vertical Escape Chute System for TEMPSC Davit Launch
TEMPSC Modification - Davit Launch Life Boat
Utilizing a Vertical Three Layer Escape Chute System
Totally Enclosed Mechanically Propelled Survival Craft (TEMPSC), more generally referred
to as Lifeboats are available in a variety of craft types; with a variety of release
gear types, engines and, davit/winch types.
They are boarded at deck level and once fully loaded the vessel is then lowered to
sea on davits or dropped free fall from a cradle. In either case the personnel are
required to embark and be seated prior to and during the launch process.
They are widely utilized by the offshore oil & gas industry as the primary means
of evacuation from a facility when Helicopter evacuation is not available. However,
as early as October 1986 (within months of their use becoming mandatory in UK), UK
regulators had become concerned at the number of reported accidents involving davit
launched TEMPSC on-load release gear.
As a result UK Department of Trade (DOT) issued an M.1248 notice reminding those
involved in lifeboat drills & tests of the need for full and regular training in
the correct use of the equipment.
Since that time and despite regular warnings from flag state administrations, underwriters
and classification societies the number of accidents and seriousness of the consequences
has continued to rise. This has lead to a number of studies into Life boat safety.
OCIMF – Results of a Survey into Life Boat Safety (Ref 2).
MAIB – Review of Life Boat and Launching Systems Accidents (Ref 5).
As a result the need for a system that would enable the TEMPSC to be launched and
then boarded was identified.
This paper sets forth a scheme for an Alternative Embarkation System for Davit Launched
TEMPSC that allows the TEMPSC to be launched with minimal/no manning; allowing the
crew to embark once the TEMPSC is safely deployed to sea level.
This document is supported by drawings, calculations and other supporting data which
are the intellectual property of Risk Safety Systems Inc. The proposed embarkation
scheme is described in summary below:
In evaluating possible options for the reduction of risks posed to personnel evacuating
from an offshore facility using a Davit Launched TEMPSC it became obvious from the
data derived from various studies referenced within this document that there existed
a primary risk driver.
That was, the need for personnel to board the TEMPSC at its stowed location at various
deck levels all of which required the TEMPSC to be lowered fully manned 30-50m to
sea level. This exposes the personnel to the risk of fall to sea should the launch
Therefore, attention was given to reducing personnel exposure to the risks associated
with lowering the TEMPSC to sea while manned. In order to significantly reduce the
risks associated with the use of a davit launched TEMPSC during an evacuation it
is necessary to minimize the exposure of the crew to the risks associated with lowering
the TEMPSC fully manned.
The implied solution is to modify the process such that the TEMPSC can be launched
and the crew board once the TEMPSC is at a safe height location at or slightly above
This removes the risk of the TEMPSC falling to sea fully loaded likely resulting
in fatality or injury to the crew.
On that basis RSS propose that a stand alone lightweight access system be installed
such that it locates a vertical escape chute over the rear top access hatch to the
TEMPSC. Figures 1.1 and 1.2 illustrate the system installed over an existing TEMPSC
station. As can be seen the system does not interfere with access for maintenance
or launch of the TEMPSC or Davits.
As can be seen the proposed system is simple, low weight, low cost and based on RSS
existing tried and tested vertical escape chute technology. The system can be installed
with TEMPSC in place with minimal interference to facility as no hot work is required
(platform is bolted into position).
In conclusion, the RSS TEMPSC Embarkation System offers a significantly reduced risk
to personnel requiring evacuation from a facility via davit launched TEMPSC for the
It eliminates risk to personnel of falling to sea in fully loaded TEMPSC should Davit
or other system fail. This implies a significant potential reduction in IRPA, PLL
or FAR for offshore facilities while not imposing significant additional costs (cost
It removes personnel from hazards at topsides enabling them to wait in the TEMPSC
at or near sea level while any final personnel missing from muster are being located.
This eliminates exposure to heat flux, flame or contamination of TEMPSC environment
by combustion products which may be more likely to occur if the TEMPSC is boarded
and loaded at deck level.
The system can be retrofitted with no significant impact on facility operations or
use of current evacuation systems.
The system is low cost and lightweight with low maintenance.
Personnel boarding time is not increased significantly by using the vertical escape
