Today,it is necessary for public
works to be low cost, high quality and environmentally friendly. This project
carries out an investigation to develop a new generation work vessel that meets
these requirements. In fiscal year 2002, the following four items of investigation
were carried out. 1) Work vessels for deeper and rougher sea areas Safe and efficient
work vessels for settling caisson in rough sea areas. 2) Investigation into new
generation power plants Investigation into a model vessel (pontoon) for clean
new energy power plants. 3) Investigation into environment protection Investigation
into business in which work vessels contribute to environment protection 4) Investigation
in work vessel for improving and maintaining existing facilities Work vessels
confined space such as lower parts of piers and wave breakers is investigated. |

This project conducts a feasibility
study on a circuit that acts as an artery in which urban waste is transported
by ship on rivers, canals and gulfs to existing treatment facilities and in which
commodities and energy are transported to cities. Such a circuit is useful for
forming a highly recycle-based society. In fiscal year 2002, the following items
are investigated. 1) A model for a ship transport system was proposed, and the
model system was investigated. 2) Information and documents are compiled for the
upper stream (compilation and transport of urban waste) and the lower stream (unloading
and waste treatment ). |

Design rules for backhoe dredgers
and crane ships were drafted, supported by the Nippon Foundation in fiscal year
2000. In fiscal year 2002, design rules for other kinds of work vessel (grab dredgers,
SPC ships, mud carrier barges) are drafted. Furthermore, the following design
manuals are drafted. 1) Design manuals for preventing vibration and noise 2) Design
manuals for environment protection (including exhaust gas treatment) 3) Design
manuals for application of information technology (IT) |

Manager of the Operation Masayasu Ogawa |
If the crew has to leave a wrecked ship in inflatable life
rafts or life jackets, recognition of their position depends on the radars of
rescue boats and rescue aircrafts. Every raft and jacket should have a radar transponder,
SART. However, under the present IMO regulations, SART is brought into the raft
when the crew leaves the ship. The disaster of the RORO passenger boat, Estonia,
in the Baltic Sea made IMO reconsider the SART requirements. At the IMO subcommittee
meeting in July 1999, the SART regulations were amended; life rafts of passenger
boats like the Estonia must always be equipped with SART. In accordance with the
amendment, the Japan Ship-Machinery Quality Association investigated the drop-type
SART in 1999 and 2000. As a result, fundamental element technology for a small
and light SART was developed. This project will produce shock a shock-resistant,
small, light SART for trial based on the fundamental element technology. Mounting
methods including auto-start of the SART are investigated to meet the IMO regulations.
The project also investigates the smaller, lighter SART for life jackets to raise
the rescue rate of crews who fall into the sea. The smaller, lighter SART is also
produced for trial, conducting further investigation into element technology. |

Section V of the SOLAS Convention of IMO is scheduled to be
wholly revised and applied from July 2002. In accordance with the revision, revision
of related domestic regulations and laws is under way. It was decided that approval
test conditions for equipment for safety navigation and automated navigation must
conform to the IEC60945 of the International Electrotechnical Commission (IEC)
that requires several approval tests under 12 conditions such as high and low
temperatures, vibration, corrosion, etc. This project investigates compatibility
of this equipment with the test conditions. It also investigates how to improve
the existing This project is to dedicated safety at sea by investigating practical
approval test conditions. |

Senior Engineer Nobuyuki Abe |
Small boats will have to be equipped with smaller life jackets
than ever as well than ordinary life jackets. The smaller jacket is for small
children and must be stable. Wearing these jackets will be compulsory for children.
In general, the floatability of a life jacket is usually examined when it is afloat
by using a test person for whom the jacket is designed. However, this procedure
cannot be applied to life jackets for children because the test method described
above is inappropriate for children. This project develops a dummy for a floatability
test of a children's life jacket, and proposes an evaluation procedure for the
children's life jacket. The project will establish the test procedure and is dedicated
to safety at sea by popularizing the test procedure. |

The following studies are undertaken to develop a marine gas
turbine for 2,500 kW class output, which performs on less than 1 g/kWh of NOx
discharge quantity (about 1/10 that of the high-speed diesel engine), has 38-40%
thermal efficiency (equal to that of a high-speed diesel engine) and uses a heavy
oil as fuel. |

2. A marine gas turbine for 2,000-kW class output that has
the necessary reliability to be installed on an actual ship is manufactured using
the new techniques obtained from item 1, shown above. At the same time, research
is conducted to improve total energy efficiency of the gas turbine (with a goal
of 50%) by adding an intake air-cooling system and exhaust gas heat recovery system
to the gas turbine plant. These systems utilize the exhaust gas energy of the
gas turbine. The following research is carried out this year, (1) Design and manufacture
of the marine gas turbine plant to be installed on a ship. (2) Research and development
of the intake air cooling system and exhaust gas heat recovery system for the
plant. (3) Reliability test of the plant. |
