Exxon Valdez

Commercial crude oil supertanker AbQaiq

Oriental Nicety, formerly Exxon Valdez, Exxon Mediterranean, SeaRiver Mediterranean, S/R Mediterranean, Mediterranean, and Dong Fang Ocean, was an oil tanker that gained notoriety after running aground in Prince William Sound, spilling its cargo of crude oil into the sea.

In terms of tonnage, 29% of ships were tankers, 43% are bulk carriers, 13% container ships and 15% were other types.

Free surface effect

Mechanism which can cause a watercraft to become unstable and capsize.

A liquid hitting a wall in a container will cause sloshing.

The free surface effect can affect any kind of craft, including watercraft (where it is most common), bulk cargo or liquid tanker semi-trailers and trucks (causing either jackknifing or roll-overs), and aircraft (especially fire-fighting water-droppers and refueling tankers where baffles mitigate but do not eliminate the effects).

Recent initiatives at the IMO have included amendments to SOLAS, which upgraded fire protection standards on passenger ships, the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) which establishes basic requirements on training, certification and watchkeeping for seafarers and to the Convention on the Prevention of Maritime Pollution (MARPOL 73/78), which required double hulls on all tankers.
