Presentation Title
Shipping Trends
• Oil ships transport liquids in bulk, wide size range
• Circa 4,000 greater than 10,000DWT, 2/3rds double hulled
• Panamax 60,000DWT to 80,000DWT
• Aframax 80,000DWT to 120,000DWT
• Suezmax 120,000DWT to 165,000DWT
• VLCC 200,000DWT to 320,000DWT (90 number)
• ULCC 320,000DWT to 550,000DWT (7 number)
• Supertanker Seawise Giant 458m LOA scrapped 2010
• LNG ships transport liquefied natural gas (1/600th volume),
have increased in size from 160km3 to 266km3 (Qmax)

Presentation Title
Oil & Gas Exports
• Growth in activity in
emerging markets
including:
• Africa – Tanzania /
Mozambique
• Brazil
• SE Asia
• Upstream and
downstream investments
required in producing
countries
• Supply bases
• Ship repair facilities
• Export terminals (import too)
• Growth in LNG
• Changes in hubs, trade flows
Presentation Title
Oil and gas port issues
• Oil & Gas industry high HSE standards
• Deepwater access – dredge depth? Tranship offshore/SPM?
• Pressure to use jetty for wide shipping range
• Pressure to use older jetties for bigger ships
• Harder to find good sites – waves, currents, siltation
• Environmental protection
• Security
• LNG considering floating solutions

Presentation Title
Jetty planning issues
• Define ships - range with min, max; manifold variation
• Water depth at berth / underkeel clearance - ships, soils, waves, passing ships
• Navigation – channel to & from berth, turning, safety
• Safety distance : other berths, passing ships etc
• Dredging versus longer trestle to shore
• Downtime at berth (waves, winds, breakwater?) & access channel/traffic impacts
• Number & position of dolphins, elevation
• Platform layout (equipment), trestle alignment (road access?), deck level(s)

Presentation Title
Typical LNG terminals
• Ships pointing seaward for ease of exit
• Wide range of ship manifold positions (+30m fwd, -5m aft)
• 4 breasting dolphins, separate from platform
• 6 mooring dolphins, 25 to 50m set back
• Ships berth one side only (port or starboard)
• Turning circle min 1.5 x LOA, preferably 2+ times LOA
• Separation to other berths & adjacent channels vital
• Water depth 13.5-15m, depends on ships, local conditions
• Design for OCIMF : 60 knot winds @ berth, currents
• Platform main deck & raised mezzanine, containment

Floating LNG : newer concept
• LNG regas ships pumping ashore gas via SPM
• LNG regas ship at berth as storage with tankers to/from
• Small LNG & CNG ships in use also
