The Seacrest Drill Ship a.k.a 'The Scan Queen'(Southern Gulf of Thailand) Depth 70meters ; Trimix diving only
Tonnage : 4,400 gross tonnage, Length : 110 m Breadth : 20 m Draught :6m
Details of Sinking:- Sunk by 'Typhoon Gay' 3 November 1989. 91 rig workers of many nationalities were killed in the disaster, leading to a massive legal case brought against the ships owners UNOCAL, Thailand(now Chevron) by over 90 bereaved relatives from around the world. After the vessel capsized and the storm blew through, the rescue authorities had problems located it, leading to the only 2 survivors of the calamity spending an unusually long amount of time in the water prior to recovery. The sinking represented the third worst oil rig disaster anywhere, though there is little or no mention of the loss on the www oil rig disaster sites.
Investigation revealed the reason the rig went over was that the drill ship had the Derrick full of 200 ton of pipe, and was still connected to the well head at the time the storm hit leading to a high C of G and compromised stability. Standard practice with this type of vessel is to lay down pipe when bad weather threatens - It is alleged that UNOCAL said "No" to stowing the pipe so as to save time resulting in 91 deaths. (see different account below) The legal proceedings that followed the sinking are mentioned by UNOCAL's legal representatives at http://www.susmangodfrey.com/clientssay.html and at http://www.susmangodfrey.com/practice/practice_foreign.html "In Sandoval v. UNOCAL, our client UNOCAL owned the drill ship Seacrest which capsized during Typhoon Gay in the Gulf of Thailand in 1989. Plaintiffs representing over 90 decedents sued UNOCAL in Texas and throughout the world. Our lawyers were required to completely learn the Thai civil code in order to defend the case." The unique character of 'Typhoon Gay' which sunk hundreds of fishing vessels with its 100knt+ winds and 40ft waves is discussed at https://www.cnmoc.navy.mil/nmosw/thh_nc/thailand/sattahip/text/sect7.htm . "Typhoon Gay hit Southern Thailand Chumphon province in 1989, the only typhoon-strength storm ever to reach Thailand in recorded history. Gay killed 529 people and left 160,000 homeless". note:- Access to the Typhoon gay data is via a secure US military web site.

Other mobile oil rig disasters include Alexander L. Kielland(123 dead-1980), Ocean Ranger(84 dead-1984) US-OIL drill ship(81 dead-1981). +++ Listings of Major Oilrig disaster are available at the following links:- http://oilrigwork.netfirms.com/Accidents.htm http://www.oilrigdisasters.co.uk
Wrecks details REPORT November 2009 Author: (name withheld - confidential) Drill Site Supervisor Seacrest In Memoriam 3 Nov 2009 The Seacrest did not have the amount of
pipe in the Derrick as mentioned by unknown persons 200 Tons is a fabrication,
she was not connected to the Wellhead the Upper Package was disconnected from
the Sub-Sea BOP. Prior to disconnecting Pipe was run to the 9-5/8 Shoe and Hung
off in the Sub-Sea BOP's leaving a majority of the Drill Pipe below the Sea Bed.
The upper Package disconnected. The Slip Joint was laid out. The TDS was secured
above the Rig Floor and remaining Pipe in the Derrick was secured. There are
many rumors as to what happened and that is what they are rumors. The actions on
the Seacrest were pieced together by radio contact up to the point of loss of
communications, interviews with survivors (witnesses) when they were rescued and
the incident fresh in their minds prior to being coerced by suggestion and
influence from other parties. I have not forgotten, many have not and never
will, some want this incident to be forgotten but that is too their shame "We
who knew them will remember them".

Anonymous Contributors - A note of thanks I am indebted to the many friends and relatives of those who perished in this sinking who have contacted me and even travelled to Thailand to meet and discuss this disaster contributing most of the information on this shipwreck disaster research page. Many still work in the oil industry and due to the politics that still surrounds this disaster have asked to remain anonymous. Many have quoted fear from the enormous negative publicity and multi-million dollar legal action kicked up by this disaster that still exists to this day, or the fear of loosing their jobs if they say anything that may considered in breach of commercial confidence. If you have any information or corrections to the data on this page that you would like to contribute anonymously, or if you would like your contact details forwarded to other personnel effected by this tragedy, please contact me, and I will forward your contact details to them for consideration in confidence. |
