Covertainer Concept

A New Generation Concept For Bulk Liquid Cargoes Transportation

SOLUTION

IS IT IMPOSSIBLE? PLEASE SCROLL DOWN

Let's Compare with Conventional Chemical Tanker

General View

Vessel Construction Cost 15-20% Less
Vessel Construction Time 10% Less
Additional Two Atlantic Voyages Annually
Increased Vessel Lifetime by Eliminating Tank Washing
Reduce Operational Costs - Maintenance Costs
Reduce Ship Crew Training Requirements and Its Cost
Reduce Ship Crew Expense
Reduce Cargo Operation Risks
Allow to Reach Autonomous Vessel
Reduce Port Stay Period
Eliminate Cargo Discharging Responsibility
Vessel Arrive To Port with Loading Guarantee
Reduce Carbon Emissions and Bunker Consumptions
Reduce Environmental Impacts Of The Vessel
Reduce Vessel Total Lost Risk

Reduce Risks of Cargo Quantity - Quality
More Protection for Cargo
No Cargo Loose
Easy Follow-Up Your Cargo

No Delay For Cargo Pool
No More Last Three Cargo Problems
Multiple Cargo Arrangement Opportunity
New Trade Routes Opportunities
Predictable Operations by Eliminating Empty Voyages and Tank Cleaning Operations

Increase Annual Cargo Handling Capacity
Multiple Cargo Storage in One Shore Tank Opportunity
Terminals Can Be Smaller with Increase Efficiency
Minimise Vessel Operation Fail & Delay Times

The advantages of the new transportation concept will impact other shipowners as well, creating a ship modernization credit pool of approximately 2 billion dollars

Know-How of New Concept
Additional Ship Modernization Market
New Orders for Ship Building

The new concept will increase the number of academic papers in universities.
The training and certifications required for the implementation of the concept will not only increase the educated workforce but also create a new education market.

The detergent and freshwater consumption used in the tank cleaning process will be eliminated.
Since the tank cleaning operation is eliminated, no residue or waste will be discharged into the sea.
The vapor of the cargo released into the atmosphere during tank cleaning operations will be eliminated.
Fuel consumption decreases because the ship does not make empty voyages and does not perform tank cleaning operations.
The ship's carbon emissions would decrease per ton annually.
Since tank cleaning operations are eliminated, the underwater noise pollution generated by the ship decreases.
Since the ship will no longer need to operate with ballast, the damage to the marine ecology is minimized.

and much more...

Project Catalogs

We are only harmonising existing technologies

Liquid Bag for Tanker

New design tanker vessel does not require cargo tank washing.
Building and management costs are reduced.
Able to load next cargo immediately after discharging her cargo.
Operation risks are reduced.

Liquid Bag for General Cargo

Solving short cargo problem of general cargo vessels.
Ship is able to carry liquid cargoes.
Increase cargo opportunities.
Does not require cargo hold washing/cleaning for liquid cargoes.

Slop Bag for Tankers

Solving empty voyage problem of Slop tank.
The bag is removed once slop transfer is completed from tank to shore.
Tank is immediately ready to load next cargo without tank washing/cleaning.

Sewage Bag General

Providing temporary solution to vessels for collecting sewage without Ballast tank cleaning requirement.

Benefits Covertainer

Covertainer system provides more reliable and effective cargo transportation opportunity.

Environment

Covertainer is a transportation system that does not harm the nature. It eliminates the need for tank washing. hence avoids water discharge into the sea and detergent usage during tank washing.

Decarbonization

It is the most effective method in reducing the amount of carbon emission during bulk-cargo transport by eliminating tank washing which uses petroleum based energy source.

Zero Pollution

Covertainer has a special structure that it prevents cargo leakage to the sea even after ship accidents by containing cargo intact in the Covertainer.

R&D

Covertainer is just a large size new generation elastic Container, Nothing Else

NO NEED TANK WASHING

Cargo loading in Covertainer Bag so tank not contaminated with cargo. If Covertainer bag is used for the same cargo, then the bag also does not need to be washed.

TARE WEIGHT

If you transport 1000mt sunflower oil then approximately 130mt Container tare weight is required. Covertainer tare weight is only 20mt for 1000mt sunflower oil.

AUTONOMOUS SYSTEM

If a vessel performs tank washings, it is not possible to adapt to the autonomous system. With Covertainer system, vessels easily adapt to the autonomous system.

We are developing Covertainer and its unique cargo operation concept

Manifesto

OPEN CALL

Dear Readers;

I’m Oceangoing Chemical Tanker Captain Guner Kara. I and My Team mates have been, working and developing for two years on a project which is eliminating Chemical Tankers’ cargo tank washing operations. We are trying to reach Washing-free transportation.

I’m preparing an article to increase maturity of this project. You can see below some parts of my article.

------------

After completion of the discharge, 75lt chemical cargo may remain in chemical tanker cargo tank as per Marpol rules.*

*Marpol Annex II / Regulation 12 Pumping, piping, unloading arrangements and slop tanks / Page 21

This chemical residue, discharged into the sea via ship’s underwater discharge line, at 12 NM from shore, 7knt under speed and more than 25meters depth of the sea.**

**Marpol Regulation 13 / Control of discharges of residues of Noxious Liquid Substances / Page 23

If this vessel has 20 pieces cargo tanks, 1.5 ton chemical cargo residue will be disposed into the sea. If this vessel performs 10 voyages per year, 15 tons chemical disposes in to the sea while tank washings annually.

Around the world, if we consider 10.000 pieces vessel perform same operation, approximately 150.000 tons chemical are disposed into the sea annually.

Styrene monomer and vinyl monomer is the base of plastic. These are used for PVC, glue and plastic paint production. These are carried in liquid form in chemical tankers and, if mixed with salty sea water, it turns to mucus form. One of the biggest sources of micro plastics in the seas is present transportation system.

- Like Phenol, Acrylonitrile cargoes are cancerogenic and highly dangerous for human health. All cargoes’ residues which we counted above discharged into the sea during cargo tank washings after unloading. All them of are common cargoes in world transportation.

The cargoes which stated as “Chemical” and Dischargeable cargoes in to the sea listed in IBC Code Chapter17.****. ****MEPC 64/23/Add.1Annex 12, page 2 / MEPC 64/WP.12 Chapter 17 of the IBC Code

Even the Ship performs washing operation with more than 7 knots; the chemical residue continues to keep its position and is not splitting. Fish and other sea life have to swim in a chemical pool. Some parts of the discharged chemical evaporates by air temperature while remain chemical residue fall down timely to the bottom of the sea due to its heavier density and become reason of diminishing the oxygen level of the sea bottom.

Around the world today more than 80.000 vessels exist at 5000DWT and more scale and approximately 20% of them are Chemical Tankers.

------------

Even if we become success on our project, maybe we can handle 10 or may be 20 different cargoes till 2030. Unfortunately there is almost 1000 different cargo existing in IBC Code and we are discharging them all.

Shortly, I wish this project had begun in 2000s and it looks like unfortunately we already missed the train. I’m not sure can we reach to all cargoes till 2040, till 2050.

But we must take attention of the people for this situation.

I would like to thank to Prof Dr Ozcan Arslan (ITU), Prof Dr Leyla Tavacioglu (ITU), Prof Dr Rafet Emek Kurt(Strathclyde, UK), Dr Cagri Unal (DEHUKAM) who support my article preparation.

Best Regards

Capt. Guner Kara
