Kicked off on May 18 with more than 70 online attendees, MARIN’s TopTier Joint Industry Project is a three year initiative focused on drastically reducing the numbers of containers lost overboard and re-establishing the confidence in safe container operations.

The size of deep sea container ships increased exponentially over the past decades. Recent dramatic losses of containers and their impact on the marine and coastal environments have raised public and political concerns on the safety and environmental impact of modern container ships. “Authorities and industry are urged to re-evaluate container securing standards and improve regulations and practices to avoid such loss of containers at sea”, states Jos Koning, Top Tier’s technical coordinator at MARIN.

Goal

The TopTier initiative builds on MARIN’s Lashing@Sea Joint Industry Project, that ran from 2006 to 2009. Now, ten years later, a series of recent incidents shows that scale effects and increased economic pressure are pushing container operations beyond safe boundaries. “The new project will identify shortcomings in the current practice and propose improvements for the coming decade that are supported by both shipping industry and authorities responsible for overall safety”, comments Gijs Struijk, Project Manager at MARIN.

Project scope

Cargo securing safety relies not only on ships being operated inside their design margins, but also on the quality of calculation models to determine these margins, the reliability of hard input facts as weights, stow configuration, strength ratings, and a regulatory infrastructure to ensure that each of these comply to minimal standards. TopTier will review these aspects over the three years of the project. The scope includes:
  • Verification of realistic ‘in-design’ limits and accurate load calculation models that take into account the large variations in loading conditions, GM, weather routing and the structural flexibility of modern ships and their high stacked cargo.
  • Provide ship crews with practical insight into actually occurring loads in relation to safe limits that are assumed within complex computerized cargo calculations.
  • Increase awareness for and ability to avoid ‘off-design’ conditions such as parametric roll, loss of stability and resonant roll.
  • Evaluate the validity of classic safety margins in relation to modern high-stacked cargo and the effect of uncertainties arising in the stowage planning and loading stage such as VGM, stacking sequence, ISO/CSC coding, corner castings and lashing gear condition.
  • Changes to the regulatory framework to ensure that improved standards are implemented and enforced from top down to have the wide impact that is needed for a safe and level playing field.

Project set-up

The work will be carried out in four phases:
  • Phase 1, starting in summer 2021, addresses the current practice, recent large scale incidents and a gap analysis in order to report first recommendations for operational improvements before fall.
  • Phase 2 including investigations such as lab testing and measurements campaigns on board.
  • Phase 3 where new technologies, design rates, calculation models and best practice will be developed and verified.
  • Phase 4 will implement the findings and submit to international regulatory bodies such as IMO, ISO and IACS through–and supported by–participating organisations.

Consortium

TopTier is organised as a Joint Industry Project to ensure wide representation and combine sufficient experience and capabilities as needed to create an effective impact of project findings. The still expanding consortium of stakeholders includes coastal and flag state administrations, major carriers, class societies, gear makers, shipyards, IT suppliers, branch organisations as WCS, ICS, IG-group, BIC and technology institutes and universities. The group brings together the expertise that is needed to review transport safety by the complex product of all its aspects: shore-based logistics, container and lashing hardware, software and technology, vessel handling at sea and the regulatory framework that is in place to ensure compliance to minimal required standards.
