JSTRA is engaged in strategic R&D to reinforce the competitiveness of the domestic shipbuilding and marine transportation industries and technical basis in the international arena. At the same time, it addresses technical challenges for the domestic industries in terms of logistical efficiency, safety assurance and environmental preservation.

JSTRA is targeting the development of measures to reduce GHG emissions based on the current status of international marine transportation. Hence, it is enforcing measures to enable early and effective implementation of the draft revision of MARPOL Convention that was established under the Japanese initiative and that is currently being reviewed by IMO.

JSTRA evaluates impacts of various Market-Based Mechanism (MBM) proposed by each country on the international marine transportation and investigates the feasibility of each mechanism.
JSTRA performs research and studies on the requirements of fuel infrastructure necessary to realize an LNG fuel ship.

JSTRA performs research on the vaporizer for ship machinery that can stably vaporize the LNG.

JSTRA performs research and studies to address reviews for a suitable IGF code (code for the gas-fueled ship being developed in IMO) based on the LNG-fueled ship concept design and its outcome.

JSTRA studies safety evaluations to realize safe transfers of LNG between ships.

JSTRA performs research on alternative anti-corrosion technologies applicable inside ballast tanks in compliance with PSPC (anti-corrosion inside ballast tanks).

 In order to implement studies on necessary technologies and standards for promoting participation in the related areas of ocean development, JSTRA analyzes current technical trends (i.e., mapping of current technologies) and screens out the technical problems based on research on overseas experiences.

Based on the results of the coating projects it has engaged in so far, various studies are carried out including applying blast technology using a mix air jet to ship repair and R&D on the cloud configuration of the support system for creating coating technical files.

 Studies on guidelines for effective use of damping material to reduce local onboard noise.

JSTRA supports technical challenges of mid-scale shipbuilders, ie a joint study of CFD for improving hull form.

JSTRA examines methods to improve the efficiency of shipbuilding including the possibility of technological development based on the recent progress of information technology.
