How 13Mari Works

13 Mari’s patented element technology reduces drag and boosts vessel efficiency through a streamlined, non-invasive process.

Schedule A Consultation

Theoretical Support

LES 4.7 m/s plate simulation with and with no elements
Two distinct mechanisms for drag reduction observed
Highly optimized SDARI's container carrier design
Self-propulsion with and with no elements

Vorticity is born as a result of stress near the rigid wall

This means a field on the body suffices in defining it

The drag is a result of vorticity flux crossing potential stream lines

The theory allows for drag increase and decrease

By stretching, the flux remains close to the body

The new vorticity born at the boundary is ~ magnitude lower

Installation

Our installation process is engineered for maximum efficiency and zero disruption. Whether in port or at anchor, the 13 Mari Elements can be installed underwater by certified divers without drilling, drydocking, or halting operations.

Quick Mechanical Fastening

Underwater Installation with Friction Welding

Optimization Process

We obtain the line plan from the shipyard.
A physical model for towing tank optimization, between 4-6 weeks, must be put in the towing tank window.
13 Mari performs digital CFD optimization at a model scale.
In parallel, towing tank work is done, including resistance and self-propulsion
With towing tank results, elements are manufactured and installed, cost dependent on vessel, and optimization results, with a 5-week lead time.
