Oil tanker (side view)
Oil tanker 1
 oil tanker = petroleum tanker
 designed for the bulk transport of oil
 Basic types:
 Crude tanker (carries large quantities of unrefined oil
from its point of extraction to refineries)
 Product tanker (smaller / carries petrochemicals from
refineries to points near consuming markets)
Oil tanker 2
 VLC – very large crude carrier (200,000 – 300,000 dwt)
 ULCC – ultra large crude carrier (> 300,000 dwt)
Chemical carrier
 = type of tanker designed to transport chemicals in
bulk
 has separate cargo tanks - coated
LPG carrier
LNG carrier
FPSO
FPSO
 = floating production, storage and offloading
 used by the offshore industry for processing
hydrocarbons and storage of oil
 hydrocarbons produced from nearyby platforms are
received, processed, stored, offloaded
Special purpose ship
 Container ship
 Ro-Ro ship
 Car carrier
 Bulk carrier
Container ship
Container ship
