Carry Out the Transfer of Product within Jetty Operations
This subtopic focuses on the practical skills and underpinning knowledge required to safely and efficiently manage the transfer of liquid bulk products (such as oil, chemicals, or LNG) at a jetty facility. It encompasses the end-to-end process of product transfer, including pre-transfer checks, monitoring flow rates, tank gauging, and the critical measurements needed to reconcile quantities transferred. Emphasis is placed on adherence to strict operational procedures, environmental regulations, and safety protocols to prevent spills, overfills, and other hazardous incidents.

Quick Revision Summary (Key Takeaway)
The City & Guilds Level 3 Diploma in Jetty Operations (QCF) covers the safe and efficient management of marine jetty facilities, including vessel berthing, cargo transfer, and emergency response. This qualification equips students with advanced skills in operational planning, risk assessment, and compliance with maritime regulations, preparing them for supervisory roles in port and harbour environments.
Topic Overview
The City & Guilds Level 3 Diploma in Jetty Operations (QCF) is a vocational qualification designed for individuals working in or aspiring to supervisory roles within port and harbour environments. It focuses on the safe and efficient management of jetty operations, covering everything from vessel berthing and mooring to cargo transfer and emergency response. This qualification is essential for those responsible for overseeing daily activities on a jetty, ensuring compliance with health, safety, and environmental regulations.
The course content is structured around real-world scenarios, requiring students to apply theoretical knowledge to practical situations. It emphasises risk assessment, operational planning, and effective communication with various stakeholders, including vessel crews, port authorities, and emergency services. By mastering these skills, students become capable of handling complex operations, mitigating risks, and maintaining high safety standards, which are critical in the high-stakes environment of maritime logistics.
This diploma fits into the broader field of Manufacturing & Engineering by bridging the gap between land-based industrial operations and maritime activities. It complements qualifications in logistics, engineering, and health and safety, providing a specialised pathway for career progression. Graduates often move into roles such as jetty supervisors, port operations managers, or health and safety officers, where they play a vital role in the global supply chain.
Key Concepts
Core ideas you must understand for this topic

Learning Objectives
What you need to know and understand
- Demonstrate the correct procedure for lining up the jetty manifold and verifying product route before transfer.
- Calculate the net volume of product transferred using tank ullage readings, temperatures, and correction factors.
- Interpret flow metre readings and adjust pump speeds to maintain transfer within safe operating limits.
- Conduct a pre-transfer risk assessment and complete the Ship/Shore Safety Checklist in line with ISGOTT guidelines.
- Apply organisational procedures for reporting anomalies or deviations during product transfer.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly identifying and operating the valve sequence for a given product line-up.
- Credit given for accurate use of tank calibration tables and volume correction factors in calculations.
- Evidence of completing the pre-transfer checklist with signatures from ship and shore.
- Correct use of the Emergency Shutdown (ESD) system during a simulated scenario.
- Demonstration of proper communication protocols with the ship’s crew and control room.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference ISGOTT (International Safety Guide for Oil Tankers and Terminals) guidelines in your practical assessment to demonstrate industry-standard knowledge.
- 💡Double-check all calculations for volume correction factors and ensure units are consistent.
- 💡Practice the sequence of actions for different product transfer scenarios, including start-up, steady state, and shutdown.
- 💡Be prepared to explain the rationale behind each procedural step—assessors look for understanding, not just rote actions.
- 💡Always use correct maritime terminology, such as 'starboard', 'port', 'mooring lines', and 'fenders', to demonstrate professional knowledge.
- 💡When answering questions about procedures, structure your response logically: preparation, execution, and post-operation checks. This ensures you cover all necessary points.
- 💡For calculation questions, show all your working and include units in every step. Even if the final answer is wrong, you can gain method marks.
Common Mistakes
Common errors to avoid in your coursework
- Forgetting to account for product temperature when calculating transferred volume, leading to inaccurate figures.
- Incorrectly aligning valves which causes cross-contamination or product diversion.
- Failing to monitor back pressure, risking hose rupture.
- Not following the exact sequence of shutdown procedures in an emergency.
- Misconception: The jetty supervisor is responsible for the vessel's safety once it is alongside. Correction: The vessel's master retains ultimate responsibility for the vessel; the supervisor is responsible for the jetty side and coordination.
- Misconception: Risk assessment is a one-time activity. Correction: Risk assessments must be dynamic and reviewed regularly, especially when conditions change, such as weather or cargo type.
- Misconception: PPE is the primary control measure for all hazards. Correction: PPE is the last resort; elimination, substitution, engineering, and administrative controls should be considered first.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on understanding the regulatory framework and key definitions. Read through the syllabus and make notes on the roles and responsibilities of a jetty supervisor.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A jetty is planning to receive a vessel carrying 10,000 tonnes of liquid cargo. The cargo transfer rate is 500 tonnes per hour. The vessel will be alongside for 2 hours before transfer starts and 1 hour after transfer ends for unmooring. Calculate the total time the vessel will be alongside the jetty.
- 1.Step 1: Identify the given facts: cargo quantity = 10,000 tonnes, transfer rate = 500 tonnes/hour, pre-transfer time = 2 hours, post-transfer time = 1 hour.
- 2.Step 2: Calculate the transfer time: 10,000 tonnes ÷ 500 tonnes/hour = 20 hours.
- 3.Step 3: Add the pre and post transfer times: 20 hours + 2 hours + 1 hour = 23 hours.
- 4.Step 4: State the final answer with units: The vessel will be alongside for 23 hours.
Question: Describe the key steps in preparing a jetty for the arrival of a vessel carrying hazardous chemicals. (6 marks)
- 1.Step 1: Conduct a risk assessment specific to the hazardous cargo, identifying potential spill or leak scenarios.
- 2.Step 2: Ensure all safety equipment is in place and tested, including fire suppression systems, spill containment kits, and emergency showers.
- 3.Step 3: Brief the jetty team on the cargo properties, emergency procedures, and their specific roles.
