Method

01 / 10

We work where the steel is — shell, tanks, holds and machinery. Every job starts with a measurement and ends with a report a class surveyor can sign.

01

Measure first

Gauging and inspection data define the scope before a single cut is made.

02

One accountable team

Steel, welding and NDT coordinated by one supervisor, from survey to sign-off.

03

Class-ready records

Drawings, readings and photos delivered in the format your surveyor expects.

[S.02]Services02 / 10

Six disciplines. One crew.

From a cracked bracket to a full steel renewal, we plan, execute and document the work around your schedule.

Measured, not guessed.

Ultrasonic gauging turns corrosion into numbers. We map it, compare it with the original plate and show exactly what needs renewal.

Base in Santos, teams in every Brazilian port

Repairs alongside: working without losing the cargo window

What it takes to do steel, welding and piping work while a ship is alongside or trading — permits, gas-freeing, access and coordination with the terminal.

MethodsNov 03, 2026

Insert plate or doubler: choosing the permanent repair

When damaged plating can be covered with a doubler, when it must be cut out and renewed with an insert, and what makes an insert right first time.
