Detecting the risk of natural disasters! Estimating, planning, and providing BCP measures tailored to your needs!

Our company, as a user-oriented engineering firm that possesses hazardous materials and high-pressure gas facilities, supports the creation of "natural disaster risk management" tailored to our customers' needs. Experienced specialists conduct on-site investigations and predict maximum values based on the recurrence periods of natural disasters such as earthquake risks. We detect equipment damage in anticipated disasters and assist our customers in formulating their Business Continuity Plans (BCP). In addition to planning and providing soft measures such as post-disaster equipment inspection manuals and damage mitigation strategies, we also propose equipment modification plans as countermeasures for the detected equipment damage in the anticipated disasters. 【Features】 ■ Predict maximum values based on the recurrence periods of natural disasters ■ Detect equipment damage in anticipated disasters and support BCP formulation ■ Plan and provide soft measures such as post-disaster equipment inspection manuals and damage mitigation strategies ■ Propose equipment modification plans as countermeasures for detected equipment damage in anticipated disasters ■ One-stop service available from disaster estimation to equipment modification design and construction *For more details, please refer to the PDF document or feel free to contact us.

Support for seismic retrofitting of spherical tanks with a consistent system! Optimal reinforcement specifications for equipment.

"Seismic Diagnosis and Reinforcement of Spherical Tanks" utilizes years of experience and a wealth of achievements as one of the few user-oriented engineering companies that own spherical tanks, undertaking everything from seismic diagnosis to reinforcement design and construction in a consistent system. In addition to evaluating the seismic resistance of the equipment itself and its foundation, we aim for comprehensive seismic reinforcement considering local ground conditions and the equipment environment. Even users who have previously given up on seismic reinforcement due to cost or feasibility concerns are welcome to consult with us. 【Features】 ■ Detailed detection of weak points in the tank ■ Comprehensive seismic reinforcement considering local ground conditions and equipment environment ■ Development of feasible reinforcement plans ■ Realistic strength verification through simulation ■ Proposal of optimal reinforcement specifications for the equipment *For more details, please refer to the PDF materials or feel free to contact us.

[Presenting case studies useful for seismic evaluation] Supporting seismic evaluation and reinforcement work for high-pressure gas storage tanks (spherical tanks, flat-bottomed refrigerated tanks, etc.)!

For high-pressure gas equipment classified as Importance I and Ia, the Ministry of Economy, Trade and Industry has stipulated the formulation of seismic reinforcement plans in the document "On Improving the Seismic Resistance of Existing High-Pressure Gas Facilities (20140519 Commercial Bureau No. 1)." Our company has been advancing seismic evaluations, studies, designs, and construction for numerous LPG storage tanks owned by the Idemitsu Group. In our studies, we applied the latest knowledge in seismic motion evaluation and developed and introduced new high-precision simulations to accurately assess behaviors such as shaking and deformation during an earthquake. Through these efforts, we have contributed to improving the seismic performance and ensuring the safety of high-pressure gas facilities by identifying reinforcement locations and subsequently selecting appropriate construction methods and carrying out reinforcement work. 【Do you have any of these concerns?】 - I want to proceed with seismic evaluation but need advice on how to do so. - There are multiple pieces of equipment that require seismic evaluation, and I want to address them systematically. - The results indicate that there are more reinforcement locations needed than expected. I want to reconfirm if this is really the case. - Area constraints may pose limitations on seismic reinforcement work. Are there any good methods available? Our experienced engineers will propose optimal solutions for seismic reinforcement. Please feel free to consult with us.

Are you struggling with the high costs of seismic reinforcement for high-pressure gas facilities? Cost reduction is possible by utilizing Idemitsu's experience and simulation technology!

[Until the end of September] You can download a paper that includes case studies of seismic evaluations of high-pressure gas tanks utilizing our simulation technology! ********************************************* [Overview] Regarding the improvement of seismic resistance for existing high-pressure gas facilities (Commercial Bureau No. 1, 20140519), it is required to formulate renovation plans aimed at seismic reinforcement for equipment classified as importance level 1.1a. At Idemitsu Engineering, we can provide optimal proposals based on case studies from Idemitsu Kosan's refineries and factories. [Features] ◆ With a highly accurate evaluation method, reinforcement costs can be minimized. 　⇒ By using "earthquake motions based on the latest knowledge" and "structural simulations," we can achieve highly accurate seismic evaluations. Consequently, it is possible to reduce reinforcement costs to the limit. (There are also cases where reinforcement was deemed unnecessary.) ◆ We have a track record of reinforcement work even in difficult and narrow locations. 　⇒ We have experience enabling construction in narrow spaces surrounded by existing facilities by adopting small pile driving machines. For more details, please contact us or download the catalog.
