Appendix B: Hull Form Development by JANSROP
When INSROP was launched, the SOF established a NSR Research Panel to implement JANSROP. Carried out in parallel with the SOF's support of INSROP, JANSROP was conceived as an NSR research project conducted with the priorities and point of view of Japan. JANSROP performed the following research activities:
* Research to find the optimum hull from for NSR (FY 1993-1995)
* Surveys and research on the basic performance required for icebreaking cargo vessels (FY 1997)
* Research and development of a numerical forecasting system for ice conditions in the NSR
The first of the above projects, research from FY 1993 to FY1995 to find the optimum hull form for NSR, can be further broken down into the following research topics.
* Model tests in ice and open water of designs for the optimum hull form
* Analysis of characteristics of propellers in ice-covered waters and of interactions between ice and propellers
* Research into the interference between floes and waves
* Analysis of sea ice data in the Arctic
In this section an overview of the data referred to in Chapter 4 is presented, focusing on research concerning the development of icebreaking cargo ships for the NSR. For further details on this research, the Annual Reports of JANSROP by the SOF are available.
This research to develop hull forms for NSR navigation was conducted in two phases, Phase I (FY 1993-1995) and Phase II (FY 1997). In Phase I, hull form development was concentrated on the design of a commercial vessel with a shallow draft, suited to the shallow waters of Russia's coastal seas. Phase II tackled the development of a ship with a deeper draft, intended for use in the deeper waters far from the shore. A crucial aspect of this research was the exploration of ways to expand the limitations on the ship's draft, so that as large a ship as possible could be built; the larger the ship is, the more competitive it becomes in comparison to the conventional Suez Canal route. Also, this research was intended to develop ship designs that could be applied in the operation simulation carried out in parallel at INSROP.
1. Development of an icebreaking cargo ship for coastal NSR navigation
For coastal NSR navigation, the hull form was developed according to the following timetable.
* Basic design (FY 1993)
Key features of the vessel were determined based on collected data on water depth and safety of ports in the NSR Candidate vessels were then designed on the basis of this data and models were produced for testing.
* Tank test (FY 1994)
Using the models designed and produced the previous fiscal year, models of each candidate design were tested in ice and open water.
* Development and testing of new ships (FY 1994, 1995)
