Marine Service International and Trussco have completed more than 500 projects worldwide, involving millions of square meters of steel repair and protection. Wherever your vessel is en route or stationed, we can rapidly mobilize teams to deliver any aspect of our services without interrupting vessel operations.
As the largest operator of UHP blasting equipment in the marine market, MSI can blast and re-coat any internal or external area whilst your vessel is in-voyage. We can also carry out all types of class approved steel repairs en-route without any impact on your operations.
Services
MSI and Trussco have experienced, multi-skilled teams equipped with the most up-to-date tools and technologies, ready to be mobilized to undertake the following services:
Tank Preparation
We can de-muck, clean, and erect scaffolding inside tanks or externally onboard your vessel to support our own repair and maintenance activities or those of third-party contractors.
UHP and Grit Blasting
Ultra-high-pressure (UHP) blasting with fresh water has largely replaced grit blasting as a surface preparation method for offshore use, and MSI and Trussco have more than 15 years of experience operating these systems worldwide. With a fleet of 25+ UHP machines designed for onboard use and a team of over 100 UHP operators, we can support blasting projects of any size.
Grit blasting remains suitable for many applications, such as preparing surfaces for SPS overlay or readying scrubbers and filters for specialty coatings, including vinyl ester glass flake products.
Coating
Using professional crews with spray-painting experience gained from coating repairs on over 500 vessels, we can repair or replace any coating system onboard.

Steel Repairs
We carry out class-approved steel repairs to all onboard structures. From welding cracks to cropping and replacing steel inserts, no project is too small—or too large—for our teams.
SPS Overlay
We have completed numerous SPS installations to restore structural strength to offshore installations. SPS is approved by all major classification authorities as an alternative steel repair method where crop-and-replace construction is difficult to execute during operations, such as on main decks or hull plating below the waterline.
UHP Cutting
We use the most modern equipment to cold-cut steel onboard for access, cropping, or removal. Piping, profiles, and steel plate up to 50 mm thick can be cut efficiently and cost-effectively using UHP water, without the need for cleaning or gas-freeing.

Skilled Team, Global Service
We carry out planned maintenance and emergency in-voyage repairs worldwide. Our highly trained, multi-skilled teams and modern equipment can be mobilized to join your vessel wherever it is located to complete repairs and upgrades to class-approved standards.
Providing high-quality welding procedures certified by DNV in accordance with ISO 9001 and approved by major oil companies, MSI is ready to mobilize to any vessel at short notice. All of our multi-skilled teams and supervisors are professional seafarers, holding maritime certification to STCW standards for in-voyage work.
