LPG tanker Crystal Sunrise (IMO 9631682) collided with crude oil tanker Astro Saturn (IMO 9235725) off Singapore at 02:30 local time on April 16th.
Crystal Sunrise had been chartered by Japanese LPG company Gyxis, while Astro Saturn was under charter to European trading house Trafigura.
The accident caused the release of about 1,800 tonnes of liquefied butane gas. Crystal Sunrise was picking up her pilot at a designated pilot station about a mile south of Tuas Extension when the collision occurred. Crystal Sunrise suffered damage to a ballast tank and a leak from a gas cargo tank. The bow and port side anchor of Astro Saturn were also damaged. The Crystal Sunrise crew managed to contain the gas leak, with the butane that had leaked being understood to have dissipated quickly, with the prevailing winds carrying it away from Singapore’s shores. “As liquefied butane has a high evaporation rate, MPA (Singapore’s Maritime and Port Authority) has assessed that any leaked butane would have been carried southward away from mainland Singapore, where most of it would have rapidly dissipated to below flammable levels within an hour and pose no risk to shipping,” the MPA said.
No injuries were reported on either vessel. The MPA said that it was investigating the collision. The ships subsequently dropped anchor at Kupuk Anchorage.
