4,900-ton - Yard Oil Tankers (YOT)

Japan's defence ministry placed an order 21 May 2020 for two oil tankers to support patrolling navy vessels particularly in the East China Sea area. Japanese shipbuilder Shin Kurushima Dockyard received an order from the ministry to build two 4,900 deadweight ton tankers for delivery targeted in April and July 2022. The two tankers are expected to be able to carry around 30,000 bl each of marine fuel and will be built at the firm's Hashihara shipyard in Ehime prefecture's Imabari.

The Japanese government allocated 6bn ($55mn) for the planned construction of Japan's first dedicated navy tankers as part of the country's 5 trillion defense budget in the April 2019-March 2020 fiscal year. The navy aimed to secure refuelling capability for its patrol vessels at frontline bases, particularly in Okinawa, without private-sector co-operation. These new vessels are about half the size of existing JMSDF replenishment ships.

Shinkurujima Dock Co., Ltd. received an order for two 4,900-ton type oil tankers (YOT) from the Ministry of Defense. As one of the projects required by the Ministry of Defense for FY 2019, this vessel has been booked with the maintenance of two oil tankers, and the purpose is to ensure support capability for the vessels. In addition, this ship is based on the specifications of domestic tankers based on general NK rules. Delivery is scheduled for April and July of Reiwa 4th year, and the company planned to build it on the Narushima Habohama Dock of the group. This is the first time the compnay had built it for the Ministry of Defense since it was founded.

Shinkurujima Hatohama Dock Co., Ltd., located at Hatohama, Imabari City, Ehime Prefecture, is the birthplace of Shinkurujima Dock. It takes pride in the solid technology cultivated in a long history and tradition since founding. The yard builds small and distinctive ships.

In order to increase production efficiency, the method of assembling small blocks, middle blocks, and large blocks in a stepwise manner is adopted. The assembled block is connected to several blocks to form a huge block, and at this point, fittings such as pipes and electric wires are attached. Most of the outfittings are installed at the block level above the ground to increase dock production efficiency. Launching at the dock is just pouring water and floating the boat, but the launch of the sill is impressed by the force that the boat slides into the sea vigorously. It is the moment to enjoy the real pleasure of shipbuilding.

According to Naval News Japan based contributor Yoshihiro Inaba, these ships will be used to transport fuel to front-line bases in Okinawa and the Nansei Islands, or to fuel anchored JMSDF vessels. As such, the tanker doesnt have fueling stations and can not perform UNREP (underway replenishment) missions. Currently, the JMSDF rely on civilian ships to transport fuel to these areas, but in case of war, the JMSDF could be denied transportation by these civilian contractors. Therefore, JMSDF will be able to transport the fuel on its own thanks to these new YOT vessels.
