Are Bulk Carriers safe?
Bulk carrier operators must be aware of the specific safety concerns related to this type of ship. Loading of cargo must be done carefully, to ensure cargo cannot shift during a voyage leading to stability problems. Large hatch covers must be watertight and secure.
What are the risks you identified in dry bulk shipping trades?
9 Common Hazards Of Bulk Cargo On Ships
- Cargo shift: Cargo shift has always remained one of the greatest dangers on bulk carriers.
- Cargo falling from height: Cargoes like iron ore, quartz and steel scraps are high-density cargo.
- Dust from working cargo: Dust is one of the most common hazards in bulk carriers.
What are the hazards of solid bulk cargo?
Carrying solid bulk cargoes involves serious risks, which must be managed carefully to safeguard the crew and the ship. These risks include reduced ship stability, and even capsizing, due to cargo liquefaction; fire or explosion due to chemical hazards; and damage to ship structures due to poor loading procedures.
Why damage can happen during cargo operations on bulk carrier ships?
Causes of bulk carrier hull damage and failure in operation. Damage to side shell, externally through contact with docksides or tugs and, internally from impact by cargo dislodging equipment during discharge, can result in initiating fractures and/or fatigue of the structure. This may lead to undetected fractures.
How much can bulk carriers carry?
Today’s bulk carriers are specially designed to maximize capacity, safety, efficiency, and durability. Today, bulk carriers make up 21% of the world’s merchant fleets and range in size from single-hold mini-bulk carriers to mammoth ore ships able to carry 400,000 metric tons of deadweight (DWT).
What are the main issues when carrying grain cargoes?
There is a possibility of cargo falling from height during cargo operations. Cargo may either fall from the conveyor belt of the shiploader or from the discharging grab on to the deck of the ship. People working on deck can get injured badly if hit by the sizeable lumps of the bulk cargo.
What types of cargo deplete oxygen rapidly?
The BC Code lists the following cargoes as potentially oxygen depleting: brown coal briquettes, charcoal, coal, copra, direct reduced iron, ferrous metal borings (shavings, turnings or cuttings), fish (in bulk), fish meal (fish scrap), iron oxide (iron sponge), metal sulfide concentrates, mineral concentrates, silico …
Which of the following is an example of a dry bulk cargo?
Dry bulk refers to grain, coal, iron ore, cement, sugar, salt and sand. They are not packaged separately, but transported in large quantities in the hold of a ship, wagon or lorry.
What is transportable moisture limit?
The Transportable Moisture Limit of cargo is the maximum gross water content by weight that liquefiable solid bulk cargo may contain during transport without risk of liquefaction.
What are the causes of damage to a bulk carrier cargo space?
Deterioration of ships hull / structure through corrosion, fatigue and damage is identified as a principal factor in the loss of many ships carrying cargo in bulk . Failing to identify such deterioration may lead to sudden and unexpected accident.
Why do bulk carrier accidents continue to happen?
Despite what should already be a good level of knowledge, bulk carrier accidents continue to happen for a variety of reasons. These risks have now drawn the attention of the industry. When bulk cargoes shift, liquefy, catch fire or explode as a consequence of poor loading procedures, the consequences can be massive.
Are dry bulk cargoes really less hazardous than liquid bulk?
Unfortunately, it is often assumed that dry bulk cargoes are less hazardous, and require less expertise, than liquid bulk or containers. This is quite clearly not the case, with some 24% of large P&I claims coming from bulk carriers, of which 40% are cargo related.
How should the bulk carrier be marked?
When restrictions on cargoes are imposed, the bulk carrier should be permanently marked with a solid triangle on its side shell. The date of application of the new Chapter to existing bulk carriers depends on their age.
What are the safety regulations for bulk carriers under SOLAS?
Following a spate of losses of bulk carriers in the early 1990s, IMO in November 1997 adopted new regulations in SOLAS containing specific safety requirements for bulk carriers, Chapter XII – Additional Safety Measures for Bulk Carriers.
