Contribute to the transfer of product in jetty operations
Overview
This standard covers the competences you need to contribute to the transfer of product in jetty operations in accordance with approved procedures and practices.
You will be required to demonstrate that you can:
1 fill pipeline with product
2 monitor transfer of product
During this work you must take account of the relevant operational requirements and safe working practices AS THEY APPLY TO YOU.
The activity is likely to be undertaken by someone in petro-chemical work setting, including individuals working in refineries, chemical plants and tank storage.
Performance criteria
You must be able to:
P1 fill the appropriate pipelines
P2 vent the air and vapour as appropriate
P3 ensure that the test-cocks are checked and fully secured after testing
P4 check that the tank valves are reset after flooding
P5 communicate all relevant information to the appropriate people
P6 deal promptly and effectively with problems that are your responsibility, and report those that you cannot solve and/or are not your responsibility to the relevant person
P7 work safely in accordance with operational and environmental
requirements
P8 obtain and confirm all relevant information
P9 monitor all relevant variables
P10 take appropriate action if any variations are unacceptable
P11 confirm that ship's personnel are monitoring the condition and of the tank atmospheres
P12 take the appropriate action if measurements and/or trends indicate that there is, or will be problem
P13 ensure that all relevant safety checks are completed according to prescribed procedures
P14 take appropriate action if vapour dispersion appears to be hazardous
P15 visually check the condition of the water around the transfer operation for any signs of pollution
P16 report results to the relevant personnel, and take appropriate action if signs of pollution are seen
P17 check all environmental conditions during transfer operation and compare with prescribed limits
Knowledge and Understanding
You need to know and understand:
K1 how and when to vent air and vapour
K2 the causes and signs of pressure problems
K3 the signs of pressure problems in pipelines and hoses (to include abnormal gauge readings; joint and valve leakage including valve passing; lifting of pressure relief valves)
K4 the causes of pressure problems in pipelines and hoses (to include pumping rates and the influence of ambient temperature)
K5 how to select, use and care for appropriate PPE (to include sight and hearing protection, gloves, footwear, hard hats, respirators)
K6 how to obtain and confirm information on flow rates, transfer rates, cargo conditions, atmospheric conditions, the equipment, vapour dispersion and environmental conditions
K7 how to monitor all relevant variables including flow rates during the transfer; line pressure; cargo conditions including temperature; the operation of transfer equipment; vapour dispersion and environmental conditions during transfer
K8 the appropriate action to take to maintain acceptable and safe transfer of product
K9 the relevant information that should be communicated
K10 how to switch tanks during a product transfer
K11 how to stop the product transfer
Scope/range
1. Fill the pipeline with product. This may include filling by:
1.1. flooding and or pressurizing
2. Monitor and compare actual pumping rates with agreed pumping rates at specified intervals, taking account of all of the following:
2.1. agreed transfer rates – initial, maximum and topping off
2.2. units of measure and terminology
2.3. pumping principles and procedures
3. Monitor actual transfer, and analyse and compare with agreed cargo transfer plan taking account of all of the following:
3.1. permitted transfer rates line pressures and temperatures
3.2. transfer procedures
3.3. pressure and liquid level limitations
4. Ensure that equipment, loading systems, cargo and return vapour hoses remain within their safe operational envelope by monitoring at prescribed intervals and taking account of all of the following:
4.1. principles and operating procedures of equipment
4.2. equipment capacities and operational limits
4.3. pressure and temperature limits
4.4. all working areas adequately illuminated
5. Ensure that vessel and terminal on going safety checks are completed in accordance with the safety checklist, taking account of all of the following:
5.1. maintaining the correct checking interval
5.2. comparing actual results with expected results
5.3. taking appropriate action if any deficiencies are revealed
6. Monitor the dispersion of cargo vapour taking account of all of the following:
6.1. properties and behaviour of vapour
6.2. formation of vapour dispersal clouds
6.3. relative density of vapours
6.4. precautions against the entry of vapours into enclosures on the terminal
7. Check environmental conditions to include all of the following:
7.1. measurement of sea swell
7.2. measurement of tidal heights
7.3. measurement of wind speeds and directions
7.4. assessment of lightning risks
