Danger of cargo liquefaction – Bulk Carriers

International Maritime Solid Bulk Cargo (IMSBC) Code categorizes cargoes into three groups, A, B & C:

A = cargoes which may liquefy if shipped at a moisture content in excess of their transportable moisture limit

B = cargoes which possess a chemical hazard which could give rise to a dangerous situation on a ship.

C = consists of cargoes which are neither liable to liquefy (Group A) nor to possess chemical hazards (Group B).

Liquefaction property of group A cargo is a major concern on safety of ship and its crew. In 2010 vessels Jian Fu Star, Nasco Diamond, Hong Wei and Vinalines Queen sank resulting in total loss of 67 lives at sea. The cargo carried by these four ill-fated vessels was nickel ore.

When liquefaction takes place vessel at sea may experience cargo shifting resulting in sudden loss of stability and capsizing.

When does liquefaction occur? Liquefaction takes place if the moisture content in cargo is above the Transportable Moisture Limit (TML).  Since Nickel ore is not listed by name in IMSBC Code the carriage of nickel ore must be within the scope of section 1.3 “Cargoes not listed in this Code”

Recommendations are submitted to Maritime Safety Committee for implementing binding rules for engagement of National Competent Authority together with qualified laboratories for assessment of moisture content, TML  to ensure cargoes which may liquefy is not loaded if moisture content is above TML.

Quote from China’s submission to Maritime Safety Committee (MSC89)

“China, as the country of nationality of the 45 seafarers [who lost their lives], carried out the investigation immediately after the accidents. In view of the fact that the subject ships had sunk and the difficulty to obtain cargo samples from the port of loading, the investigation was mainly based on the interviews with the surviving seafarers.

According to the evidence available, the direct cause of these accidents was the loss of stability as a result of cargo liquefaction and shifting in bad weather. However, the cargo documentation provided to the masters indicated that the moisture content of the cargo samples was lower than the Transportable Moisture Limit (TML)”.

Celebrating 10,000 and 1 Readings

A long international  voyage of an unknown sailor and his small occasion to celebrate.

Anno Domini 15th October 2010 evening I shutdown my office workstation (at Maersk) and walked off to the retired life at the age of 40. I didn’t had much plans in my life other than relaxing in my home town, a small city, Calicut, fanned by gentle breeze from Arabian Sea.

Back at home, Bombay, on that evening I made a blog account thinking I will narrate my long journey in life.

Why long journey in life by 40, because I always followed my heart. A life’s journey followed by heart is much longer than a scheduled journey, because the true happiness is in journeying not in the destination.

I always followed my heart, where I loved to stay I stayed long, where I didn’t love to stay I moved on. When I was sailing on long voyages I loved the staying in the going. When I stayed long during breaks in sailing or worked on storage tankers moored to SPM many nautical miles off the shore I loved the going in the staying.

In between sailing I took a break of 2 years and lived in West Africa,  Tema and Abidjan mainly, involving myself into  various aspects of port operations related to MPVs. It was one of the best days in my life spent in gold coast and ivory coast.  Once I sat Hours and hours at Cape Coast Castle where 100s and 1000s of slaves were held captive before their fateful voyage across Atlantic commenced.

I was also involved in transporting ECOWAS Soldiers to Liberia for peace keeping mission, a life time experience of loading and discharging armored cars, ammunition and heavy artillery into and out of the cargo holds. Arranging the logistics for 1000 plus soldiers to sail on ship, installing their military radio station and antenna ,testing their radio. Communication was HF SSB Radio Telephony and Morse code. I felt am a soldier without uniform. Oops! I felt a soldier in Merchant Marine uniform 😉

Later during 1999 coup in Ivory Coast I had to save myself  from looting, arson, gunshots and finally flee the country with nothing but the cloths I wore and my passport. Of course when I got out of then Sahar airport I had the stub of the air ticket additionally together with cloths I wore,  passport and a one rupee coin which had hid itself in my jeans pocket. I walked from Sahar airport (Mumbai) , some 20 odd kilometers, to D.N. Road and borrowed a pen to fill up withdrawal form at my bank. The meal I had then at a restaurant is the best I ever had in life though cockroaches were playing on the table.  I lost many of my documents and a box full of old photographs and negatives I had with me. I hadn’t changed to digital camera then,  technologically less savvy I am. But those memories I still cherish in my heart.

Remembering those good old days I still some time test my ability to key Morse code.

Coming back to the immediate days after leaving my last job and opening blog account, I sat  in front of my laptop thinking what to write and where to start. I entered some small notes on dangerous goods; a topic  very fresh in my mind after working 8 years in P& O Nedlloyd and Maersk dangerous goods department.

My blog entry was very infrequent through the months. Later one day I received an email from Microsoft stating that they are stopping the blog service and it will be automatically transferred to WordPress. I obliged and moved all my previous  ‘rare’ entries on to WordPress.com

My entries during September and October 2011

13 entries in Sept 2011 is accumulated figure from Oct 2010.

Then at home town I bought a mountain bike and started cycling. Hitting out on the road before sunrise coasting Calicut’s beach road and turn back home from Beypore port some 17 kilometers one way.

Ability to read is a real gift, with this gift we can immerse ourselves into the world of literature. I indulge myself into reading any book I come across be it political, historical, religious or atheist. When I look back at my working days and now the graph of reading hasn’t changed much as reading was always part of me.

From Milton’s Paradise Lost , through Dostoyevsky’s Crime and Punishment or Tolstoy’s Anna Karenina or Khayyam’s Rubaiyat one can spent his life journeying through letters. Need not mention Don Quixote of Miguel De Cervantes which makes me feel am another Ingenious Gentleman Don Quixote of Calicut 🙂

Back at blog, during my interaction with various people in industry I realized there is definitely a lack of general understanding in dangerous goods transportation. How to rectify it? Training, already made mandatory by IMO. Yes training is mandatory and is undertaken by many.

But training starts and ends within a scheduled timetable. What happens if the trainee had any doubt many days, weeks or months after training? This was the question pondering my mind. Who will answer him or her? Whom the trainee can approach post training with a specific question?

Then late in November 2011 I decided to write on blog again. But what to write? I started recalling what I used to ask myself during my initial days in dangerous goods safety department and on those topics I started writing on blog.

How much more I wrote? In November 2011 I wrote one more entry

End November my blog entry status looked like this.

Watching the visitor status I felt I am the most frequent visitor reading my blog through admin panel but later the number of visitors started growing. The topics they read made me understand what information they are looking for. This encouraged me to write more and more.

End December my blog entry status looked like this.

Then I got a Class 1.4S fireworks email from WordPress.com celebrating my blog status 😉

Blog Visitor Status – Months and Years

I realized that when I write more number of visitors are increasing, compare no. of entries and visitors for Oct, Nov and Dec below.

This encouraged me to write more about what readers are looking for and my status went on to end of March 31st as below

Across the globe there are dedicated people ensuring compliance to SOLAS, 1974, as amended, and MARPOL 73/78 for safety and environmental protection during transport of dangerous goods.

I am happy to serve those who are looking for information about safe transport of dangerous goods by Road, Rail, River and Sea. Its my duty to give back to the industry what it taught me!

Today I will celebrate passing the milestone of 10,00th reading of my safety blog with “BEER”, because

“An aqueous solution containing not more than 24% alcohol by volume is not subject to the provisions of IMDG Code.” 😉

IMSBC Code Training

International Maritime Solid Bulk Cargoes , IMSBC,  Code supersede Safe Practice for Solid Bulk Cargoes. IMSBC Code became mandatory from 1st January 2011.

Annex 4 of IMSBC Code is pertaining to training of terminal personnel involved in loading or unloading of bulk carriers

Ship pumping ballast water

Below is quoted from Annex 4 of IMSBC code

— quote —

Loader/unloader operator training should include:
1.  The general hazards of loading and/or unloading Bulk Carriers (ref. BLU Code (Code of Practice for the Safe Loading and Unloading of Bulk Carriers) and BC Code (Code of Safe Practice for Solid Bulk Cargoes))

2.  The dangerous effect improper loading and/or unloading can have on a ship.
Practical aspects to be included in the training should include:

The BLU Code so that they understand and appreciate both the obligations it places on their  terminal,  and  the  limitations  of  the  ships  the  terminal  personnel  are  loading  and/or  unloading.

The correct operating instructions for the ship loader or unloader they are operating.

A  basic  understanding  of  the mechanical  and  electrical  components  of  the  loader  and/or unloader  such  as  travel  drives,  braking  arrangements,  ropes  and  rope  care,  grab/trolley  winches, conveyors, operating and wind limits, storm anchoring.

Emergency procedures such as fire on ship, terminal, or loader and/or unloader; mooring incidents, emergency stops.

The correct techniques and patterns to be used to  load or unload a ship, depending on  the  type of and number of loaders or unloaders being used.

To load a ship:
Loader operators should have an appropriate understanding of how to:

Distribute  the  cargo  in  each hold  in  accordance with  the  agreed  cargo plan  to  ensure  the ship remains upright, and is neither stressed nor twisted.

Ensure  no  hold  is  overloaded  or  overfilled,  and  that  the  ship  can  be  safely  trimmed  on completion.

Ensure loading efficiency is maximized, as per the agreed loading/deballasting plan.

Ensure safety and environmental protection procedures are followed.

Ensure  that  good  communications  are  maintained  between  the  loader  operator  and  the designated ships officer, and between master and terminal representative.

To unload a ship:
Unloader operators should have an appropriate understanding of how to:
Unload the cargo from each hold in accordance with the agreed unloading plan  to ensure that the ship remains upright and is not stressed or twisted.

Remove the cargo from the holds by either grab or continuous unloader in a manner that minimizes the risk of damage to the ships structure.

Ensure  that  good  communications  are aintained  between  the  unloader  operator  and  the designated ships officer, and between master and terminal representative.

Assess the risks arising from cargo sticking in frames and on hopper sides and facilitate, if possible,  its safe  removal without  risk  to  the safety of  terminal personnel and ships crew members, or risk of damage to ship.

Terminal representative training
The terminal representative should:

1. Have a thorough understanding of the underlying principles related to the loading and/or unloading of bulk carriers as described in the BLU Code.

2.  Know how to implement all aspects of the BLU Code.

3.  Understand  and  manage  the  ship/shore  interface  in  relation  to  the  operations  and limitations  of  the  terminal,  its  cargo  handling  equipment  and  procedures,  the  planning, control  and  monitoring  of  cargoes,  relevant  properties  of  the  cargoes  being  handled, berthing/mooring operations and emergency procedures.

The training, assessment and certification of trainees should be carried out by competent persons within the framework of existing training standards and national health and safety legislation
