Media not entering the water, ISO 8501-1 Sa2½ not compromised
Surface preparation in marine environments faces unique challenges in environmental compliance, regulatory constraints, and logistical support, making sandblasting increasingly difficult to approve. MontiPower tools eliminate three core obstacles: the risk of media entering the sea, ATEX zone restrictions, and containment facility requirements—while maintaining treatment standards exceeding ISO 8501-1 Sa2½.
Why do ocean projects require different solutions?
In marine environments, traditional sandblasting faces multiple challenges, including stringent environmental compliance, limited space, and logistical constraints.
Corrosion rate of seawater
The marine environment significantly accelerates corrosion processes. Coating failures on hull plates, shell plates, and pier steel structures require swift and effective treatment to prevent structural damage.
Abrasive fallout issue
Grit blasting operations on board while berthed or at anchor present serious environmental compliance issues. The release of grit blasting media into port waters or the high seas will trigger regulatory restrictions and penalties.
Flammable Goods and ATEX Zones
Tankers, LPG carriers, and offshore supply vessels contain ATEX zones. Traditional grinding and sandblasting are strictly prohibited or severely restricted in these areas.
Empty space vs. cabin space
Double-bottom tanks, ballast tanks, and void tanks are among the most corrosive environments on ships, and their confined spaces and poor ventilation pose significant challenges for traditional sandblasting.
Dry Dock Costs and Turnaround Times
Dry dock time is extremely costly; for large vessels, losses can reach hundreds of thousands of RMB per day. Reducing sandblasting time directly lowers overall repair costs and vessel downtime.
High-Altitude Work Platform & on Water
Maintenance of pier piles, overwater bridge structures, and topsides of offshore platforms requires lightweight, portable tools that can be reliably used during rope access or EWP (Elevated Work Platform) operations.
MontiPower Advantages
Proven Across Chinese Ports, Shipyards & Offshore
MontiPower Bristle Blaster and MBX tools achieve ISO 8501-1 surface cleanliness comparable to ISO 8501-1 Sa2 ½ & Sa3 (11mm BB belt, Rustgrade D) without a single gram of blast media entering the marine environment. The same tool achieves both surface cleanliness and the 40–100 µm Rz angular anchor profile required by marine coating specifications such as NORSOK M-501 and major shipyard specs.
In China, MontiPower tools are used on port infrastructure, naval vessels, commercial shipping, offshore petroleum platforms, and marine construction projects. Chinese shipyards
MontiPower Applications in Offshore Engineering
From shipyard and dry dock maintenance to offshore platforms and port quay structures – the same tool series covers all scenarios.
Hull & Topsides Local Repairs
Local coating failure treatment for hull and shell plating. Replaced traditional spot blasting with a media-free alternative, eliminating the need for onshore containment, and can be performed afloat or in dry dock.
Double bottom tanks and ballast tanks
In-tank maintenance and coating in confined spaces - axial tools handle complex shapes without contaminating the cabin environment.
Offshore platform structure
Partial Corrosion Treatment of Offshore Platform Decks, Columns, and Supporting Structures – ATEX certified, without production shutdown.
Port and Bridge Steel Structures
Maintenance treatment of jetty piles and marine bridge structures can be carried out by rope access or EWP, without entering the water.
Superstructure and side panels
Maintenance of ship superstructure and side shell plating – suitable for afloat construction, no drydock required.
Marine Standards and Compliance
ISO 8501-1 Sa2½ — MontiPower tools are independently certified to provide a surface cleanliness comparable to ISO 8501-1 Sa2½ and Sa3 (11mm BB abrasive belt, rust grade D), meeting major marine coating specifications. ATEX II 2G/2D certified documents are available upon request.
