Achieving TMSA 3 Compliance for Elements 4, 5, and 6

achieving TMSA 3 compliance with ShipNet - Part 2

In the first part of this series of TMSA 3 articles, we took a closer look at how ShipNet can assist tanker companies with implementing TMSA 3 compliance. We reviewed the first three key elements consisting of Leadership and the safety management system, recruitment and management of shore-based personnel, and recruitment, management, and wellbeing of vessel personnel, and how exactly ShipNet can help to ensure compliance with these elements.

In this next article, we review the following three elements from the thirteen key elements of TMSA 3, which are:

4. Vessel reliability and maintenance including critical equipment
5. Navigational safety
6. Cargo, ballast, tank cleaning, bunkering, mooring and anchoring operations

So, let’s get started.

4th Element – Vessel reliability and maintenance including critical equipment

Vessel reliability and maintenance including critical equipment

The 4th element reviews how Ships maintained to a high standard, impacts how safely and efficiently goods are transported, while also having a significant impact on the costs of operating a vessel. It is therefore required of Ship Operators to implement procedures that review equipment regularly whether it be mechanical, electrical or other to ensure that hazardous scenarios do not arise in line with the ISM Code.

An effective planned maintenance system that utilizes defect reporting and close-out procedures help to ensure a vessels’ clarification status while also ensuring spares are available for planned maintenance work.

How can ShipNet help with the 4th Element of TMSA 3?

The work planning module provides a complete overview of all tasks and enables a fleet to be kept up-to-date on all planned or unscheduled maintenance work. The module is integrated with our purchasing and safety modules, aiding with class and critical tasks by establishing processes for additional approvals, risk assessment, or controls for deferring.


The built-in dashboards and reports provide a real-time overview of KPI’s by monitoring overdue maintenance, critical equipment and work procedures, the status of essential spares, and to keep track of targets. The interactive dashboards not only provide a visualization of data but enable users to open relevant records and act directly.

Smart Data:

Capture structural integrity data such as tank inspections or crankshaft deflection along with planned maintenance work orders with automatic trending in the system using dashboards


Ensure vessels are compliant with all statutory and trading certificates in our compliance module. Stay up to date with automatic triggers and alerts for certificates requiring action.


Keep your critical spares list up to date with our Mobility platform, which lets you perform inventory audits, and scanning on the go. With the Future planning module built into the system, plan for critical jobs, and order spares in time using the integrated procurement system.

Keep Improving:

Keep improving the planned maintenance system through a formal change request process for monitoring and implementation of changes and correction to maintenance information within the platform.

5th Element – Navigational safety

Navigational safety

The 5th element looks at how a maritime business and a master of a vessel are responsible for a vessel’s safe navigation and are required to implement and maintain procedures that ensure navigational safety.

How can ShipNet help with the 5th Element of TMSA 3?


The document system makes all procedures accessible across an organization, with the added ability to create virtual manuals as well as specific manuals to assist masters and vessel officers.

Create and publish comprehensive navigational procedures to cover all stages of a vessel’s voyage, such as the below:

  • Bridge manning levels.
  • Calling the Master.
  • Navigation with Pilot aboard.
  • Navigating in heavy weather/restricted visibility/ice.
  • Management of lengthy periods with increased bridge manning.
  • Hazardous navigational transits.
  • Use of the BNWAS.
  • Use of electronic navigational aids.
  • Under keel clearance.


The built-in Navigational Assessments Module contains electronic checklists which can be accessed by the master to assess the preparation of the bridge team. From the Navigational Assessment checklist non-conformities, observations, or created action points. Additionally, the Navigational Assessment Checklist is accessible on Mobility, updating on the go. An organization can share best practice across the fleet and ensure continual improvement of the navigational safety culture.

6th Element – Cargo, ballast, tank cleaning, bunkering, mooring and anchoring operations

Cargo, ballast, tank cleaning, bunkering, mooring and anchoring operationsThe 6th element relates to the structural safety of a vessel and how it is heavily reliant on planned harmonious operations for cargo, ballast, tank cleaning, bunkering, and mooring.

TMSA 3 outlines industry best practice guidelines for all cargo related operations, which include IBC, IMSBC, BLU. CSS codes, IMO, ICS, ISGOTT publications, and BLU Manual.

How can ShipNet help with the 6th Element of TMSA 3?


The ShipNet Planned Maintenance module enables regular inspections and checks of all related equipment to be performed, including:

  • Line and Valve Settings
  • ESD system operation
  • Cargo/bunker line pressure testing
  • Alarms and trips
  • IGS and venting system
  • Loading computer or alternative calculations
  • Cargo and ballast pump tests
  • Gas monitoring equipment
  • Tank gauging equipment
  • Prevention of freezing

Records in the form of work orders, checklists, or forms can be maintained and submitted by vessels within the platform. The solution provides an easy to understand task standard, assisting the ship to have access to the relevant guidance for inspections and testing.

In the third part of this series of articles; looking at how the ShipNet Safety XE application and the Planned Maintenance Module of the Technical XE can help with TMSA 3 compliance, we will be reviewing the 7th, 8th and 9th elements, covering management of change, incident reporting, investigation and analysis, and safety management, so stay connected.
