Nickel ore liquefaction remains a key point of concern for shipowners and charterers, argues Janice Dao Yeung Yeung, Senior Claims Executive, Lawyer, Skuld P&I Club, who provided a detailed analysis of the regulatory obligations surrounding the nickel ore cargo from the Philippines and Indonesia for masters, charterers, owners, shippers, as well as insurers.
Liquefaction risks of nickel ore cargoes from Indonesia and the Philippines have been a long-standing prominent issue which require constant vigilance and review by shipowners and charterers.
Since 2010, the liquefaction of nickel ore cargoes has caused the capsize of seven vessels. The recent capsize of MV Emerald Star in October 2017 once again demonstrated the importance of strict compliance with the IMSBC Code (2016 edition) and the other relevant international conventions.
With the rainy season approaching, it is now a good time to revisit this issue.
General comments about nickel ore in the Philippines and Indonesia
The Philippines and Indonesia are the major suppliers of nickel ore cargoes. For the Philippines, the popular loading areas are Surigao, Tubay and Davao where the traditional dry season is usually from November to April. However, global warming and fluctuations in weather patterns have long since extended the rainy season and shortened the traditional ‘dry season’.
Like the Philippines, the dry season for loading in Indonesia at ports such as Buli, Gebe and Pomalaa runs from November to April, but this too has been curtailed due to changing weather patterns.
One major difference between the nickel ore loading industries in these two countries is, however, that while IG Clubs have been able to establish close connections with their approved and qualified local correspondents/surveyors in the Philippines throughout the years, such connections remain less developed in Indonesia since the ban of nickel ore exports in 2014. This ban was only lifted in 2017. It will therefore take time to establish the same intelligence level as in the Philippines.
What is the IMSBC Code?
The IMSBC Code is the convention that governs the safe carriage of solid bulk cargoes. This became a mandatory instrument under SOLAS Convention in 2011.
To address any new risks arising from the carriage of solid bulk cargo/enhance the safety in such carriage, the IMSBC Code is revised from time to time to ensure any prominent risks to the crew and the ship are properly managed and safeguarded. The latest edition of the IMSBC Code was published in 2016.
What are Group A Cargoes?
Under IMSBC Code (2016 edition), solid bulk cargoes can be classified into three categories and among these, Group A cargo is that which may liquefy if shipped at a moisture content (MC) in excess of their transportable moisture limit (TML).
Is nickel ore a Group A cargo?
By its nature, nickel ore is a cargo which may liquefy if the MC of the material exceeds its TML. As such, this belongs to the Group A cargo under the IMSBC Code (2016 edition).
What sections of the IMSBC Code are relevant?
For easy reference we set out herewith the relevant sections of the IMSBC Code (2016 edition) below:
SECTION 1 – General provisions
1.4.1. The provisions contained in this Code apply to all ships to which the SOLAS Convention, as amended, applies and that are carrying solid bulk cargoes…
1.4.2…this Code is legally treated as a mandatory instrument under SOLAS Convention…
SECTION 4 – Assessment of acceptability of consignments for safe shipment
4.2.1. The shipper shall provide the master or his representative with appropriate information on the cargo sufficiently in advance of loading to enable to precautions which may be necessary for proper stowage and safe carriage of the cargo to be put into effect.
4.3.1. To obtain the information required in 4.2.1, the shipper shall arrange for the cargo to be properly sampled and tested. The shipper shall provide the ship’s master or his representative with the appropriate certificates of test, if required in this Code.
4.3.2. When a concentrate or other cargo which may liquefy is carried, the shipper shall provide the ship’s master or his representative with a signed certificate of the TML (Transportable Moisture Limit) and a signed certificate or declaration of the moisture content, each issued by an entity recognized by the Competent Authority of the port of loading
4.4.2. Sampling shall be conducted only by persons who have been suitably trained in sampling procedures and who are under the supervision of someone who is fully aware of the properties of the consignment and also the applicable principles and practices of sampling.
4.4.3. For a concentrate or other cargo which may liquefy, the shipper shall facilitate access to stockpiles for the purpose of inspection, sampling and subsequent testing by the ship’s nominated representative
Cargoes that may liquefy
7.1.2. A ship’s motion may cause a cargo to shift sufficiently to capsize the vessel. Cargo shift can be divided into two types, namely, sliding failure or liquefaction consequence. Trimming the cargoes in accordance with the Code can prevent sliding failure.
7.2.3. A cargo shift caused by liquefaction may occur when the moisture content exceeds the TML. Some cargoes are susceptible to moisture migration and may develop a dangerous wet base even if the average moisture content is less than the TML. Although the cargo surface may appear dry, undetected liquefaction may take place, resulting in shifting of the cargo.
184.108.40.206. Concentrates or other cargoes which may liquefy shall only be accepted for loading when the actual moisture content of the cargo is less than its TML.
What are the shippers’ obligations?
Shippers are obliged to:
- Provide Owners/Master with:
(i) accurate information of the cargo before loading
(ii) signed certificate of the TML of the cargo
(iii) signed certificated or declaration of the moisture content of the cargo
- Facilitate access to stockpiles for sampling
- Arrange samples to be properly tested
Although the Code sets out shippers’ obligations very clearly, in reality they were rarely complied with. For instance:
- Shippers certificates: Very often the shippers’ certificates are forged. The MC or TML declared by shippers are often inaccurate and the error can be as much as 10%.
- Sampling during loading: Local shippers/mines are very influential organisations and they are often armed. When a Master or local surveyors keep rejecting bad cargo, local surveyors might receive death threats from shippers. Moreover, dry cargoes can be placed onto wet cargo as disguise. From our experience, even for samples collected at dry season, they still failed the lab test.
- Stockpiles: The stockpiles are also owned by the powerful shippers/mines. The stockpiles are normally located in remote locations and access is often rejected. The stockpiles are seldom covered hence are exposed to the prevailing weather.
- Location of loading areas: As mentioned above, the stockpiles and loading areas are usually located in very remote areas with restricted access. The loading areas are often ill-equipped and loading often takes place at anchorage owing to the absence of any proper loading port.
- Loading from barges: Owing to the lack of proper loading facilities, loading often takes place at anchorage using barges. Like the stockpiles, the barges are seldom covered and are also exposed to the weather. Moreover, where there is more than one vessel loading in one area, a barge being rejected by one vessel will be presented to another. In the absence of a good surveyor onboard, one may end up having to load cargo that has been rejected by other vessels, without any treatment or sun drying.
- Commercial pressure: Masters are always under tremendous commercial pressure from local shippers or Charterers to load the off-spec cargoes since any stoppage causes delay and time loss. During rainy seasons, there may be 24-hour non-stop loading, with wet cargo being dumped into cargo holds at night. As such, although legally (under SOLAS) the Master has overriding authority not to load or to stop loading off-spec cargo, this is easier said than done.
- Value of can test: The can test remains the conventional method adopted by Masters/local surveyors to decide whether a cargo should be rejected or not. However, can tests are only be able to identify samples with obvious signs of moisture; the actual moisture content and TML can only be ascertained under lab tests – not with the naked eye. One reason being that clay, an essential element of nickel ore, holds considerable moisture and naturally absorbs water. With the continuous vibration of a vessel during sea passage, cargoes that contain high moisture content and TML become unstable which may lead to a change in the cargo structure, from solid to liquid form. This would cause instability to the vessel, resulting in listing or even capsizing.
Guidance for Master
Skuld has prepared a guidance to Masters/local surveyors on what they should do when loading nickel ore.
It is a mandatory requirement for Members loading Group A cargo to notify their P&I Club to avoid any prejudice to their insurance cover.
When deciding whether or not to load the cargo, the Master should check for any red flags:
a) Rainy weather or typhoon seasons
b) Mines, stockpiles and barges not covered
c) Forged or inaccurate moisture content and TML level in the cargo certificates or declaration
d) Absence of proper loading facilities
e) Intimidation or death threats to local surveyors by local shippers or mines
f) 24-hour continuous loading and dumping of wet cargo at night
g) Long sea passage for the voyage
If any of the above exist, Members are strongly recommended to contact their P&I Club immediately and appoint the local correspondent, surveyor and/or cargo expert (where appropriate) to assess the situation.
What happens if loading has already commenced when these red flags emerged?
If red flags are evident once loading has begun, the Master should order loading to stop at once, and get the local correspondent and surveyor appointed via the P&I Club as soon as possible. In the worst-case scenario, the wet cargo onboard may have to be off-loaded; where off-loading is impossible, it may be necessary to arrange a cargo expert to see whether any measures can be taken to treat the cargo to bring it within the IMSBC Code parameters. A naval architect may also need to be involved since the liquefaction of cargo would have an impact on the stability of the vessel.
Needless to say, in such circumstances further delay and time loss will occur.
What is Charterers’ obligation?
Having already examined shippers’ obligations in loading Group A cargo, it remains apparent how difficult it is in reality to make shippers comply with their obligations. As such, if you are a Charterer in the charterparty chain, you need to understand your legal obligations and ensure that you have fully discharged them.
Under English law, the House of Lords decision The Giannis NK  A.C. 605, held that dangerous cargo refers “to cargo which directly or indirectly causes some sort of physical damage to life, the ship or other cargo, or raises a threat of it, leading to delay and/or other expense for the carrier”.
Generally speaking, a Charterer is under a strict liability only to load safe cargo onto a vessel even in the absence of any express terms/requirement in that respect. Pursuant to The Giannis NK, the “shipper undertakes not to ship goods which are liable to cause damage to the vessel or other cargo shipped thereon without giving notice to the shipowner of the character of the goods”.
Meanwhile, as mentioned above, the Clause Paramount imposed an absolute liability on Charterers only to load safe cargo.
What are Owners’ obligations?
Owners are obliged to provide a seaworthy vessel under the charterparty.
At the same time, Owners (being, in practice, the Master) bear the primary responsibility to allow only safe and compliant cargoes to be loaded.
BIMCO has recommended the following clause for solid bulk cargo that can liquefy:
- The Charterers shall ensure that all solid bulk cargoes to be carried under this Charter Party are presented for carriage and loaded always in compliance with applicable international regulations, including the International Maritime Solid Bulk Cargoes (IMSBC) Code 2009 (as may be amended from time to time and including any recommendations approved and agreed by the IMO).
- If the cargo is a solid bulk cargo that may liquefy, the Charterers shall prior to the commencement of loading provide the ship’s Master, or his representative, with all information and documentation in accordance with the IMSBC Code, including but not limited to a certificate of the Transportable Moisture Limit (TML), and a certificate or declaration of the moisture content, both signed by the shipper.
- The Owners shall have the right to take samples of cargo prior to loading and, at Charterers’ request, samples to be taken jointly, testing of such cargo samples shall be conducted jointly between Charterers and Owners by an independent laboratory that is to be nominated by Owners. Sampling and testing shall be at the Charterers’ risk, cost, expense and time. The Master or Owners’ representative shall at all times be permitted unrestricted and unimpeded access to cargo for sampling and testing purposes.If the Master, in his sole discretion using reasonable judgement, considers there is a risk arising out of or in connection with the cargo (including but not limited to the risk of liquefaction) which could jeopardise the safety of the crew, the Vessel or the cargo on the voyage, he shall have the right to refuse to accept the cargo or, if already loaded, refuse to sail from the loading port or place. The Master shall have the right to require the Charterers to make safe the cargo prior to loading or, if already loaded, to offload the cargo and replace it with a cargo acceptable to the Master, all at the Charterers’ risk, cost, expense and time. The exercise by the Master of the aforesaid rights shall not be a breach of this Charter Party.
- Notwithstanding anything else contained in this Charter Party, all loss, damage, delay, expenses, costs and liabilities whatsoever arising out of or related to complying with, or resulting from failure to comply with, such regulations or with Charterers’ obligations hereunder shall be for the Charterers’ account. The Charterers shall indemnify the Owners against any and all claims whatsoever against the Owners arising out of the Owners complying with the Charterers’ instructions to load the agreed cargo.
- This Clause shall be without prejudice to the Charterers’ obligations under this Charter Party to provide a safe cargo. In relation to loading, anything done or not done by the Master or the Owners in compliance with this Clause shall not amount to a waiver of any rights of the Owners. Where this BIMCO clause is incorporated, Owners would be in a much better position since it does not only allow the Master to reject cargo at his sole discretion, but also that any delay or time loss whatsoever related to the cargo quality issues will arguably be on Charterers’ account. Further (by virtue of paragraph (d) above) Charterers expressly agree to indemnify Owners for all the resulting losses. This clause would make Owners’ lives much easier and a Master would be in a stronger position to reject off-spec cargo.
Charterers in the middle – time charter in and voyage charter out?
Even in the absence of the aforesaid BIMCO clause, the un-amended NYPE form imposes on time charterers the primary responsibility for loading, stowing and trimming the cargo. If shippers fail to provide accurate cargo certificates and the cargo liquefies, time charterers will also be liable to Owners under the express charterparty terms/breach of IMSBC Code and SOLAS Convention.
Furthermore, time charterers are under a general implied indemnity to Owners against the consequences of following time charterers’ orders, including orders to carry a particular cargo.
As such, there are more than sufficient grounds on which an Owner can hold time charterers liable for their losses resulting from cargo liquefaction. That is probably the reason why Owners sometimes may not appoint a local surveyor to monitor the loading as they would have fairly high chance of success in passing any claims and/or losses down to time charterers.
By contrast, unlike time charterparty, English law does not generally find such an implied indemnity under a voyage charterparty. Thus, when time-chartering in the vessel, and voyage-chartering her out, the time charterers should incorporate the Clause Paramount and where possible, the BIMCO clause for solid bulk cargo that can liquefy (mentioned above), to maintain a back to back position.
Prior to fixing the voyage charterparty, the time charterers should also make sure that the voyage charterers are of good financial standing and that they are entered with a reputable P&I Club (preferably an IG Club).
To summarise, Members can now see that they should strictly follow the IMSBC Code, SOLAS, ISM etc., and the recommendations made by their P&I Club (and the IG). In loading this kind of volatile cargo Members should put their P&I Club on notice well in advance, as failure to do so could cause severe and adverse consequences, including the invalidation of the P&I insurance cover.
For example, the removal of off-spec cargoes itself cost several millions of US dollars; in the event of a capsize, the cost of the loss of life goes well beyond monetary terms.
Prevention is always better than cure.
In short, in view of the catastrophic outcome that a cargo’s liquefaction can cause, Members should notify their P&I Club well ahead of time if they are going to load nickel ore cargoes. And Members should always act in accordance with the recommendations of their P&I Club – arrange a pre-loading survey well in advance so that local correspondents and surveyors can be appointed to guard against any bad cargo being loaded in the first place.
Meanwhile, at the stage of fixing the charterparty Members should ensure that all necessary protective charterparty clauses are incorporated and where there is any doubt, please contact your P&I Club at once for assistance.
