This page provides an overview of the facilities owned by Yokosuka Shipyard, our base factory.
it is possible to manufacture multiple ultra-large steel structures in parallel by dividing a single dry dock with an intermediate gate.
1.Dry Dock:
The dock capable of draining seawater for the construction and repair of ships and offshore structures.
Our dry dock is 80m wide and 580m long, with access to the sea from both the north and south sides.

2.Goliath Crane (2 each):
These are large cranes that straddles a dry dock and a large space beside the dock.
Our drydock has two Goliath cranes, each with a lifting capacity of 300 tons.
The two machines can also work together to lift structures weighing up to 600 tons.

3.Hammerhead Crane (2 each)
Like the Goliath crane, two each of mobile cranes (25t capacity) are located on the side of the dock.

4.Jib Crane
This mobile crane with 25ton capacity is located on the outfitting wharf.

5.Dry Dock Tunne
Our dry dock has a tunnel and is accessible by automobile from the ground.

6.Crew Office
This is an office and waiting area for the crew to stay during the day.
This office is located between the outfitting wharf and the dry dock, providing easy access to the construction/repair site.

7.Outfitting Wharf
This is a quay where newbuilding/repair ships are moored.
It is 650 meters long and is equipped to moor several medium-sized vessels at the same time.
It is equipped with two each of elevator towers and a jib cranesfor efficient operation.

8.Intermediate Gate
The dry dock is located near the middle of ther dry dock, allowing one side of the dock to remain dry while the other side is being flooded.

9.Paint Shop
We have 10 large capacity of painting shop, which can be directly accessed by self-propelled carts with a carrying capacity of 300 tons.
Temperature and humidity can be controlled inside the building.
The coating quality is uniform throughout the year without being affected by the season/weather.

13.NC Cutting Machine
This is an NC cutting machine designed for the precise cutting of steel materials. Our company has seven plasma cutting machines and one laser cutting machine at its disposal.
The plasma cutting machine is capable of cutting steel materials with a thickness of 15mm at a speed of 2m/min, and can cut up to thick plates with a thickness of 40mm.
The laser cutting machine, on the other hand, operates at a slightly slower pace than the plasma cutting machine, but it offers greater precision and is capable of cutting thin sheets of 7-10mm.

14.Pressing Machine
This is a hydraulic press machine dedicated to cold bending processing, which bends steel plates. Our company has two presses, one with a 750-ton capacity and the other with a 1,500-ton capacity.
It can process steel plates up to 6m wide and 4m long. The maximum number of plates that can be processed is 5 per day per machine.

15.Lifting Magnet Crane
This crane is employed for the unloading of steel materials delivered by sea.
The lifting capacity of the crane is 30 tonnes.
