  • Specialty/Fine Chemicals
  • Consumer Chemicals
Brief Description of what it does

A chemical tanker is a merchant ship designed for the bulk transport of chemicals. According to the MARPOL Convention tankers can by of different types depending on the category of chemical it is carrying:

(a). Category A: Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a major hazard to either marine resources or human health or cause serious harm to amenities or other legitimate uses of the sea and therefore justify the application of stringent anti-pollution measures.

(b). Category B: Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify the application of special anti-pollution measures.

(c). Category C: Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a minor hazard to either marine resources or human health or cause minor harm to amenities or other legitimate uses of the sea and therefore require special operational conditions.

(d). Category D: Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a recognizable hazard to either marine resources or human health or cause minimal harm to amenities or other legitimate uses of the sea and therefore require some attention in operational conditions.

 

Part 2. Hazard Information

Hazards that can impact the asset.
Heat waves, cold snapstick
Floods / costal floods 
Forest Fires 
Droughts 
Sea level rise 
Ice, frost, permafrost 
Storm surges, wavestick
Lightning / thunderstormtick
Earth movement caused by climate drivers such as rain (landslide, erosion, avalanches, rock fall, soil subsidence, liquefaction, etc.) 
Description of the impacts of each hazard (as selected in the table above) on the asset.
HazardImpacts on Asset
Cold snaps

Excessive low temperature can lead to freezing of certain fluids impairing the functionality of some critical systems if not adequately accounted for during design phase (e.g. freezing of water in firewater system).

Potential formation solids (e.g. waxes, hydrates, etc.) inside process lines.

Some geographical areas might not be suitable for operations during cold season.

Storms surges, waves / Extreme wind

Heavy sea state can lead to structural damage or stop of activity as precaution to avoid incidents.

Inability to maintain a fixed position during chemical loading/offloading leading to interruption of activities.

Potential failure of anchor lines.

Lightning / thunderstormOperations limited or prohibited, potential damage to instrumentation if lighting protection not properly designed.
 

Part 3. Information on Dependencies and Interdependencies

Dependency: is a uni-directional linkage or connection between two assets belonging to the same or different infrastructure (sub)sectors, through which the ability of one infrastructure to provide a service is dependent on the operation of the other infrastructure but not vice versa. For example, infrastructure asset A1 depends on B1, but B1 does not depend on A1 to sustain its service level.

Interdependency: is a bidirectional relationship between two infrastructures through which each infrastructure mutually influences or is associated to the other. More generally, two infrastructures are interdependent when each is dependent on the other, for example, infrastructure asset A1 depends upon D1 and D1 depends on A1.

The following types of (inter)dependencies should be identified, where applicable, (Rinaldi et al):

Physical (inter)dependency: A physical (inter)dependency arises from a physical linkage between the inputs and outputs of two infrastructures. For example, if B1 is an electricity asset and A1 belongs to a water network, then a physical type of link exists if A1 requires electricity (from B1) to operate.

Cyber (inter)dependency: An infrastructure has a cyber (inter)dependency if its state depends on information transmitted through the information (ICT) infrastructure.

Geographic (inter)dependency: A geographic (inter)dependency occurs when assets of multiple infrastructures are in close spatial proximity. An example of a geographical (inter)dependency may arise if. e.g., a water pipe breaks causing flooding that impacts the assets of the same sector or other CI sectors in the vicinity of the pipe. An event (e.g., the disruption of Asset A1) can create changes in the operational state of Assets B1, C1 if they are located in spatial proximity (periphery) of Asset A1, thus establishing an ad hoc geographic interdependency.

Logical interdependency: Two infrastructures are logically interdependent if the state of each depends on the state of the other via a mechanism that is not a physical, cyber, or geographic connection. Logical interdependency is attributable to human decisions and actions.
