Block blasting in shipbuilding industry

Of the many industries involved in surface preparation the ship building and repair block sector is one of the most demanding. Following the identification of the correct equipment MRO experience ensured a very high level of support to the shipyard - operation and maintenance training were instrumental in the smooth and safe start-up.

MRO has more than 15 years’ experience in offering Surface Treatment Solutions in Viet Nam. MRO equipment is used in some of the World’s harshest environments in industries as diverse as metal & steel construction, shipbuilding, petrochemical, oil & gas, wind energy and more.


The challenges in block blasting operations is the management of the abrasives used in blast cleaning.
New abrasive needs to be loaded into silos ready for depositing into blast machines, and spent abrasive needs to be removed from the blasting location for disposal.

When used for ship block blast rooms the vacuum recovery unit is integrated with Mobile Blasting Recovery System. Collected abrasive is deposited into the recycling system for processing to remove dust and unwanted contaminants.


 1.     Mobile Blasting Recovery Systems (MBRS)

The mobile blast & recovery system is designed for surface preparation treatment in blast room and internal of tank (cargo & ballast).

Due to mobility of the system, the blasting operation can be set up within a short period of time on site and coupled with the usage of recyclable blasting media (steel grit/shot) it offers high cost savings to the blasting process.


2.     Vacuum Recovery System (ABVR)

Vacuum Recovery System is designed to recover spent dry recyclable abrasives from a blasting area into a silo for subsequent return to the blast cleaning equipment or in case of expendable abrasives, for disposal into waste hopper

After  depositing abrasive into the silo, the vacuum flow containing air and dust continues on to the section unit, where the dust particles in the stream are removed by high performance filter cartridges prior to exhausting air to atmosphere.


3.     Dust Collector

The DC Series Cartridge Type Dust Collectors are extensively used worldwide. They are equipped with advanced filtering devices and dust removing devices with optimum working performances. Our technicians have abundant professional knowledge and will forward with you shoulder by shoulder –from analyzing your dust questions to help you design a set of dust removing system that will accompany your thriving businesses. Once you own this kind of equipment, our service network and high quality spare parts will ensure the optimum status.


4.     Dehumidifier

In tropical regions this can be a major problem as the rainy season can last for weeks and bring production to a standstill. MRO’s solution is able to maintain relative humidity levels at 40% RH during blasting and clean up. With a relative humidity level of just 40% RH the risk of flash rusting is almost completely eliminated, providing more time between blasting and painting

Dehumidifiers are designed to provide the optimum climatic conditions for blasting by reducing the relative humidity
