Production, shipment and quality control system
Liberty Navigator

A networked control system that manages production, shipment andquality is mounted, enabling quick and efficient daily operation ofcomplex compounding calculation as well as massive amount of forms
processing on paperless basis.

Purpose-built inboard testing room

Full-automatic compression tester, test kneading mixer, and circulatorof constant temperature water are provided in the purpose-built
inboard testing room. This facility makes it possible to conduct
compression test or concrete test kneading swiftly in the same way
as is conducted in the onshore plant.

Placing crane : SKK-D60H

EMS mixer that can deal with any concrete slump
at full capacity

Elba EMS mixer (3 m3/B) performs quick and intensive mixing
through up-down and right-left fluid repetitive movement enabling
less uneven mix of material, which produces excellent strong anduniform concrete in a short time. The mixer has high wear
resistance with easy maintenance.

Eco-friendly waste water treatment system
The drainage from cleaning and residual water go through theclassifier inboard and the gravel, sand and sludge in the water areseparated. Supernatant as well as filtered sludge water after
dewatering is reused for kneading. The separated gravel, sand andthe dewatered cake are then brought to land for disposal.

Automatic ballast adjusting device

Marine-environment compatible distributer with a30-meter boom enables direct placement as well as
high-quality underwater placement.

The device automatically adjusts trim and heel of the hullby inclinometer and liquid-level gauge.

Transportation capacity 400 t/h
Flexible and elastic cleat rubber carries aggregate
vertically. Compared with conventional steeply
inclined conveyor, it is environment friendly
because of being almost free from load spill, andless likely to cause dust emission and scattering.

Placing crane : SKK-D60H

Batcher plant

Spud with hydraulically poweredrack and pinion
1.3 m square column, total length : 25 m (effective length : 15 m)
It stabilizes the hull, thus enhances accuracies of mix weighing
and test data.

Elba EMS Mixer (3 m3/B) installed
It can produce 192 m3 of concrete per hour :3.0 m3 x 64 B/h = 192 m3

Three-arm hydraulic placing boom
Length 30 m
Outreach (bow side) 26.9 m
This enables to place concrete directly and underwater.

215 m3 x 8 tanks

Equipped with 8 aggregate storage tanks, eachhaving capacity of 215 m 3, Kan-ei can flexibly
cope with construction works in coastal areas
and remote islands where securing freshwateror good quality of land sand is difficult.

Aggregate storage tank

Shore ramp

Equipped with 8 storage tanks with capacityof 215 m3 (4 for gravel and 4 for sand)Heat insulated roof controls the rise intemperature of the aggregate and thus,
ensures the good quality.

It allows direct access by large mixer trucks andpumping vehicles.
On-site concrete production and shipping out by
concrete mixer vehicles make it possible to reduce
the effects on the environment by emission at thetime of transportation from onshore plants.

Cement silo
Four 150-ton silos with4700 mm in outer diameter.
