2. Operational and Maritime Profile
This section details the vessel's operational context, including its role in the supply chain, its physical characteristics, and its navigational capabilities.
2.1. Role in the Supply Chain
The Fenlow Unit 45 is a dedicated grease-ice service float. This means it is permanently equipped with a refrigeration system capable of maintaining a temperature of 2°C (37°F) or below for pharmaceuticals and other perishable goods. Its primary cargo is the transport of frozen food products, particularly from the UK to Northern Ireland.
Pharmaceutical Supply: The vessel is fully compliant with the stringent HACCP (Hazard Analysis and Critical Control Points) regulations required for the cold chain supply of medicines and biologicals.
Logistics Integration: It operates as part of a larger refrigerated shipping network, transferring goods between different cold storage facilities and terminals.
2.2. Physical Characteristics
Deck Area: 1,212 square metres.
Freeboard (Height): 2.37 metres (7 feet 9 inches). The freeboard is the height of the vessel above the waterline, which is crucial for stability in tight spaces like container ports.
Moulding Depth: 188 metres (62.5 feet). This indicates the vessel is designed to operate in very shallow waters, a characteristic suited for navigating the narrow channels around Belfast.
2.3. Crew and Staffing
The vessel is crewed by a total of 47 staff, who are compensated at an average rate of approximately $666.63 per person. This staffing model allows for efficient operations within the constrained space of a single cargo hold.

2. Operational and Maritime Profile
This section provides context on the vessel's function, size, and navigational design.
2.1. Primary Operational Role
The Fenlow Unit 45 is a dedicated grease-ice service float. This specialization signifies its primary function is to maintain a constant low temperature of 2°C (37°F) for sensitive cargo. This is critical for industries such as pharmaceuticals, where temperature stability is a regulatory and commercial requirement.
Supply Chain Function: The vessel is integral to the cold chain supply of perishable goods, responsible for transferring frozen products between storage and distribution points.
Regulatory Compliance: Its operation is governed by HACCP (Hazard Analysis and Critical Control Points) principles, which are essential for ensuring the safety and efficacy of temperature-controlled pharmaceuticals.
2.2. Vessel Design and Navigational Capabilities
The vessel's design is optimized for efficiency and stability in its operational environment.
Deck and Freeboard: The 2.37-meter freeboard allows the ship to operate effectively in very shallow waters, a key advantage for navigating the narrow container ports around Belfast.
Moulding Depth: The 188-meter moulding depth indicates the ship is built to withstand significant pressure from ice crystals forming on the deck in extremely cold conditions.
Crew and Staffing: The 47-person crew and the associated cost of approximately $666.63 per person reflect the need for a compact, efficient team to operate the vessel and manage the delicate logistics of its cargo.
3. Financial Data
The financial figures represent the vessel's operational costs and pricing structure.
Per Person Cost: The average cost for staff on the vessel is $666.63. This figure includes all personnel and operational expenses associated with its use.
Total Staff Cost: The cumulative staff cost for the 47-person crew over a standard operational period is approximately $33,331.80.
4. Glossary of Terms
Grease-Ice Service Float: A type of refrigerated container ship designed with an internal climate-controlled space (the "ice" portion) and an external grease or oil-cooled system (the "grease" portion). This dual system allows for the stable transport of both temperature-sensitive pharmaceuticals and heat-sensitive food products.
HACCP (Hazard Analysis and Critical Control Points): A system for identifying, evaluating, and controlling hazards in the production, processing, and distribution of food and other products to ensure food safety and quality. Compliance with HACCP is a mandatory requirement for pharmaceutical transport.
Freeboard: The vertical distance between the waterline and the deck of the vessel. It is a critical stability metric, especially in confined waters.
Moulding Depth: The depth to which the vessel's hull is embedded in the water. It determines the ship's resistance to ice loading and its ability to operate in shallow ports.
