These competencies are essential for preventing accidents, minimising downtime, and ensuring compliance with rigorous maritime and environmental regulations.
Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in Jetty Operations (QCF) provides foundational knowledge and skills for working safely and effectively in jetty environments, typically within ports, harbours, or oil and gas terminals. This qualification covers key areas such as vessel mooring, cargo transfer operations, emergency procedures, and environmental protection. Understanding jetty operations is critical for ensuring the safe handling of bulk liquids, gases, or dry cargoes, and for maintaining compliance with health, safety, and environmental regulations.
This diploma fits within the broader Manufacturing and Engineering sector by focusing on the logistical and operational aspects of marine terminal activities. Students learn about the equipment used (e.g., loading arms, hoses, mooring lines), the principles of safe cargo handling, and the importance of communication between jetty personnel and vessel crews. The qualification also emphasises risk assessment and incident response, preparing learners for roles such as jetty operator, terminal operative, or marine assistant.
Mastery of this topic is essential for anyone pursuing a career in port operations, logistics, or the energy sector. The practical skills and theoretical knowledge gained are directly applicable to real-world scenarios, from routine berthing and unberthing to managing spills or fires. By the end of the course, students should be able to demonstrate competence in key operational tasks and understand how their role contributes to the efficiency and safety of the entire supply chain.

- Demonstrate isolation of equipment by following a lock-out tag-out sequence, including checking zero energy state, as per organisational procedures
- Show evidence of monitoring by completing a maintenance log sheet or check-list, noting any anomalies and actions taken
- Reference specific sections of the organisation's policies (e.g., Permit to Work, COSHH, emergency response) when explaining compliance
- Produce a correctly completed permit to work and handover certificate for a given maintenance scenario
- Award credit for accurately identifying and reporting defective equipment using the correct documentation and communication channels.
- Evidence must show safe isolation and lock-out/tag-out procedures followed when bringing plant or equipment out of operation for maintenance.
- Learner must demonstrate systematic monitoring of the maintenance operation, confirming completion and verifying that equipment is returned to service in accordance with procedures.
- Credit is given for adhering to organisational policies, including safety checks, permit-to-work systems, and recording all actions as required.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always relate your answers to recognised industry codes such as International Safety Guide for Oil Tankers and Terminals (ISGOTT) or organisational standard operating procedures
- 💡When describing equipment isolation, mention the specific sequence: shut down, lock-off, verify, and issue permit, emphasizing zero energy verification
- 💡Use correct technical terms for jetty infrastructure (e.g., dolphins, fenders, mooring hooks, vapour recovery systems) to demonstrate knowledge depth
- 💡For assessment, provide concrete examples from work experience or simulations, showing step-by-step adherence to policies rather than generic descriptions
- 💡In practical observations, clearly narrate your actions to the assessor, linking each step to the relevant policy or risk control measure
- 💡Always reference specific organisational procedures and risk assessments in your evidence, as this shows deeper understanding.
- 💡When identifying defects, demonstrate a methodical approach and clear communication with relevant personnel, including reporting any immediate risks.
- 💡Document every step of the isolation, maintenance, and reinstatement process meticulously to prove compliance and competence.
- 💡Practice monitoring tasks to include a final verification check and formal handover, as this is a key assessment criterion.
- 💡Always refer to the specific procedures in your workplace or training manual. Examiners look for evidence that you can apply standard operating procedures (SOPs) correctly, not just generic knowledge.
- 💡Use correct terminology (e.g., 'spring lines', 'breasting lines', 'loading arm') to demonstrate technical competence. Avoid vague terms like 'ropes' or 'pipes'.
- 💡In written answers, structure your response logically: start with risk assessment, then describe the sequence of actions, and finish with checks and handover. This mirrors real operational practice.
Common Mistakes
Common errors to avoid in your coursework
- Mistaking symptoms for root causes, e.g., repairing a leaking seal without identifying misalignment or wear as the underlying issue
- Failing to isolate all energy sources (electrical, hydraulic, residual pressure) before maintenance, risking injury or damage
- Overlooking the need for gas-free certification or atmospheric testing before commencing work on cargo systems
- Not updating maintenance records promptly, leading to gaps in traceability and potential non-compliance
- Assuming equipment is ready for service without conducting post-maintenance functional tests
- Failing to correctly identify equipment defects due to inadequate inspection techniques or rushing checks.
- Not following proper isolation procedures, risking accidental re-energisation or unintended operation.
- Overlooking monitoring steps, leading to incomplete maintenance or failure to confirm safe reinstatement.
- Ignoring organisational policies such as forgetting to obtain permits or missing required sign-offs.
- Misconception: Mooring lines can be handled without gloves. Correction: Mooring lines can cause severe friction burns; always wear appropriate gloves and use proper handling techniques.
- Misconception: Cargo transfer can proceed without constant monitoring. Correction: Continuous monitoring of pressure, flow rate, and hose condition is essential to prevent overfills, leaks, or ruptures.
- Misconception: Emergency shutdown systems are only for major incidents. Correction: ESDs should be used for any abnormal situation, including minor leaks or equipment malfunctions, to prevent escalation.
