About Lifeboats that are Resilient against Tsunami and Floods
It is assumed that the great tsunami by the Tokai/ Tonankai/ Nankai earthquake it is supposed that will be now on arrives at the coastline in several minutes.
It is difficult for the local residents especially persons in need of aid in the event of disaster like small children, the elderly, the physically disabled or the infirm who lives in the area which has neither heights nor a high building in the neighborhood and where installation of a refuge tower etc. to take refuge to a distance. So installation of refuge accommodation has been a problem in the neighborhood.
In order to protect residents' lives, our company as an only domestic specialized lifeboat manufacturer developed the new resilient lifeboat against tsunami and flood Life Seeder which can be installed ashore by lifeboat manufacturing development technology including the special technology of free fall lifeboat manufacture which does not have damage to a lifeboat not to mention the safety of a human life, either, even if a crew boards and it falls from 22 m in height.
We have two kinds of lifeboats that are resilient against tsunami and flood. Type 1 is equipped with shock absorbing material and Type 2 is equipped without it.
We got approval of “the guideline for lifeboat against tsunami” from Shikoku Transport & Tourism department of Ministry of Land and Infrastructure Transport and Tourism of Japan（JG）.
Type 1 was designed considering the following:
- The flow velocity setting to tsunami generating at the latest time is assumed to be 10m/second
- The intensity design at the time of a head-on collision.
- The allowable acceleration less than 13G and HPC (head performance criterion) less than 100 for the passenger.
Type 2 is designed for the purpose of the introduction to areas where the tsunami height and tsunami flow velocity are reduced by shock absorber and time course.
Our Life Seeder has the following advantages, originality, and conveniences compared with other similar products:
a) By development of the shock absorbing material suitable for the form of prototype lifeboat in FEA analysis and its attachment angle, the safety to much more human life is collateralized at the time of shock.
b) The following specifications were used by considering persons in need of aid in the event of disaster.
- It can be boarded at a slope by lowering stern door low to a ground clearance of 1 m.
- The door has also been enlarged and the ease of carrying out of boarding on a stretcher etc. was secured.
- The interior of the lifeboat is a plane from a stern door and makes seating and stretcher installation easy, and has become barrier-free (impediment removal).
Furthermore, in order to ensure a calm environment, we developed a maximum height of 2.0 m and a breadth of 2.3 m in the lifeboat.
c) As it is processing into the slip stopper and plane on the hull upper part, it can be used as a waiting position at the time of rescue by a helicopter.
d) As it is the self-standing type equipped with the tripod, it can be easily installed ashore before or after a disaster. And it can be used also as a temporary accommodation space, a store room, etc.
In addition, although the engine is carried in a lifeboat, an engine is not carried in the Life Seeder in consideration of the acquirement of vessel license and maintenance.
TYPE I （We got approval of “the guideline for lifeboat against tsunami” from Shikoku Transport & Tourism department of Ministry of Land and Infrastructure Transport and Tourism of Japan（JG））
As our lifeboat is equipped with shock absorbing material, the shock at the time of a collision is absorbed and passengers' safety can be ensured.
(The flow velocity is assumed to be 10m/second)
Number of seats: 25 Length: 8.7m Breadth: 3.5m Height: 3.0m
This lifeboat was developed for the purpose of the introduction to areas where the tsunami flow velocity is reduced.
It can be used also as an emergency shelter in the event of flood damage.
