Underwater Hull Inspection & Cleaning

Overview

CARGOWARD® provides underwater services in Brazil for trading vessels that need measurable results within a port call window. Our certified divers operate with shore-based coordination and a technical reporting mindset—each job is scoped by area, executed with clear limits, and closed with organized evidence and traceable records in accordance with NORMAM-401/DPC (Brazilian Navy/Directorate of Ports and Coasts) and other applicable port and environmental requirements under the current regulatory framework.

We support two common objectives:

1. Understand condition (inspection with verifiable photo/video), and/or

2. Improve underwater condition (biofouling removal, propeller polishing, rudder/appendage detailing, sea chest cleaning where feasible).

When stakeholders request class-facing documentation, we can structure outputs to match the style typically expected for review under DNV, ABS and BV practices (scope-dependent).

Choose your scope (pick what you need)

A) Inspection only (evidence-first)

• Hull/appendages visual check with photo/video capture

• Notes by zone (boot-top / flat bottom / appendages)

• Clear recording of constraints (visibility, access, currents)

B) Cleaning for biofouling control

• Hull biofouling removal to an agreed coverage plan

• Area-by-area progression with before/after evidence

• Method aligned to coating condition and limitations

C) Performance works (propeller & steering surfaces)

• Propeller polishing (surface condition improvement)

• Rudder cleaning and appendage detailing (where feasible)

• Thruster areas subject to access and local restrictions

D) Sea chest cleaning (feasibility-based)

• Executed only where safe access/design allows

• Scope and limits defined upfront (no surprises)

How we run the job (what happens during your call)

Step 1 — Feasibility snapshot

We confirm if the port/anchorage rules, currents, visibility and working window allow the requested scope.

Step 2 — Area map + sequence

We map the scope by area (what is included / excluded) and set the execution sequence.

Step 3 — Evidence capture and close-out

We capture structured evidence during execution and close with a consolidated package that states what was done, where, and under which constraints.

Evidence & reporting outputs

• Photo/video set organized by zones/areas

• Short technical notes (condition, coverage, limitations)

• Close-out summary suitable for internal records

• Optional: report pack structured for technical/class-facing review (scope-dependent)

Team & qualifications

Operations are executed by certified commercial divers with a structured approach for stakeholder reporting. When required, evidence and summary formats can be aligned for review under expectations commonly associated with DNV, ABS and BV (as applicable to scope and client request).

Ports & operating modes

We support underwater operations across major Brazilian ports and anchorages, subject to local rules and feasibility. Execution may be alongside or at anchorage depending on restrictions, safety controls and window.

What we need from you (to mobilize fast)

• Port/anchorage + ETA/ETD + available window

• Draft and any restricted areas

• Selected scope (A/B/C/D above)

• Any reporting deadline or stakeholder format requirement

• Known constraints (visibility/currents/local restrictions)

Operational limits

• Visibility, currents and access define coverage and time

• Sea chest work is feasibility-based and design-dependent

• Cleaning approach is chosen to respect coating condition and agreed limits
