LPG & LNG Operations

Storage & Transfer

Day 2 will display and stress the optimal design and construction of different types of cargo containment systems for LPG/LNG are permitted by the IGC code, and the two main types of LNG containment systems in use in the world tanker fleet are membrane tanks and independent tanks. 

Storage Tanks

• Piping & Pumping arrangements on Gas Tankers & Terminals
• Different tank configurations
• Tank Inspections & Cleaning
• Compressors & Liquefaction Plants
  
  

Transfer Systems

• Submerged & Deep Well Pumps Design and Operation
• Piping Systems
• Flow and Pressure Matching
  
  

Ship-shore Transfers for LPG/LNG

• Marine Loading Arms
• Lightering
• The Ship / Shore Safety Checklist

Terminals & Vessels Cargo handling

Day 3 would start with a discussion of different cargo containment systems will be introduced & discussed.  For example, in membrane tank designs, the cargo containment system consists of a very thin invar or stainless-steel double-walled, insulated cargo envelope structurally supported by the ship’s hull. The spherical tank carriers, also called Moss tankers, have spherical aluminium or prismatic-shaped stainless-steel tanks that are self-supporting within the ship’s hull. The day extends towards the more technical overview of the interaction process between gas tankers & terminals.

Safety and Risk

Main types of LNG hazards

Day 4 will open a seminar discussion revolving around the basic properties of LPG and LNG vapour and their associated hazards. Delegates will be able to fully understand the consequences of releasing LPG/LNG gases into the atmosphere and the dangers of direct contact with the cryogenic liquid to humans, which would potentially freeze the point of contact and damage the tissues of humans, animals and aquatic fauna. Embrittlement leading to structural failure and equipment damage may also occur when materials not designed for such low temperatures come into contact with LNG.

Ignition Sources

• Electrostatic Charge
• Hazardous Zone Classification
• Intrinsically Safe Equipment
• Brittle fracture and alloys
  
  

Fire Fighting & Protection

• Fire Detection Systems
• Fire-fighting Systems for gas release 
• Shipboard Firefighting Systems (Gas Carriers)
  
  

Risk

• Risk Assessments in Gas Tankers and terminals 
• Risk Management
• Qualitative and Quantitative Risk Assessment Techniques
• Seminar Discussion

Gas Ship/Terminal Management


The LPG/ LNG industry has learned lessons from its past and established one of the best safety records in any industry. At the heart of this success story is a firm commitment to risk assessment and management tenets. Day 5 will focus on displaying best practices to maintain that good record on Gas terminals and onboard gas ships.
