DEMINETEC in Bangkok

DEMINETEC operates in Bangkok

DEMINETEC, a French company headquartered in La Seyne-sur-Mer (Var), delivers civilian demining (pyrotechnic clearance) and unexploded ordnance (UXO) risk management services to public and private clients in Bangkok, Thailand. We cover the full chain from historical pyrotechnic desk study (EHT) to ordnance neutralisation and disposal, in line with French Decree 2005-1325 and international best practice.

Pyrotechnic historical context of Bangkok

Bangkok was a strategic target of U.S. and British heavy bomber raids in 1944 and 1945 during the Pacific campaign. The Bang Sue and Makkasan rail yards, the Memorial Bridge, the Bang Pakong oil refinery and Japanese-occupied port facilities were repeatedly bombed, leaving an unexploded-ordnance legacy that surfaces during foundation works in central Bangkok and along the Chao Phraya river.

The Thai-Cambodian and Thai-Laotian borders, together with the southern provinces (Yala, Pattani, Narathiwat), carry a significant residual UXO and landmine legacy from the Second Indochina War spillover, the Khmer Rouge period and the southern insurgency. The Thailand Mine Action Centre (TMAC) coordinates clearance with international partners (HALO Trust, NPA, MAG).

Bangkok's mega-projects — Orange and Purple metro lines, U-Tapao and Suvarnabhumi airport expansion, Eastern Economic Corridor (EEC), Map Ta Phut port — together with offshore petroleum and LNG projects in the Gulf of Thailand, increasingly include UXO desk studies and magnetometric surveys aligned with IMAS standards and the French Decree 2005-1325 reference framework.

Our services in Bangkok

Historical pyrotechnic desk study (EHT)

Document research in national and foreign archives to qualify pyrotechnic risk on a site (bombings, combat, depots, ranges).

War history and explosive contamination in Bangkok

Bangkok was repeatedly attacked by Allied aircraft because it served as a logistical and command centre for Japanese operations in Southeast Asia, including the Burma and Malayan campaigns. Japan invaded Thailand on 8 December 1941, and Thailand subsequently signed an alliance with Japan on 21 December 1941 and declared war on the United States and Great Britain on 25 January 1942. The first raid occurred during the night of 7–8 January 1942, when Royal Air Force aircraft from Rangoon attacked military targets including Hua Lamphong railway station and Memorial Bridge. Reported bomb impacts also affected Charoen-Sawat Bridge, the Ministry of Interior building, Bang Rak Hospital and the seven-storey building in Yaowarat. A second raid took place on 24–25 January, followed by a final RAF Blenheim raid on 28 January.

From late 1942, United States Army Air Forces, Royal Air Force and other Allied aircraft attacked Japanese installations, the Port of Bangkok and the Thai railway system. Targets included Khlong Toei port, Bang Sue Arsenal, Samsen and Wat Liap power plants, the Bang Sue marshalling yard, Don Muang Airbase and the Chao Phraya River estuary at Pak Nam, where a minelaying mission was conducted. On 5 June 1944, 98 B-29s were dispatched against the Makasan railway yards; only 18 bombs struck their intended targets, while other bombs destroyed a Japanese military hospital and damaged the Japanese secret police headquarters. Allied attacks continued through 1945, including strikes on Don Mueang, Rama VI Bridge, Wat Liap power plant and canal locks near Bangkok.

Expected ordnance and implications for survey

The attacks involved aerial bombs dropped by Bristol Blenheim, B-24 Liberator and B-29 aircraft. On 18 April 1945, eight Liberators each carried seven 1,000-pound bombs during an attack on canal locks near Bangkok. Some bombs were reported as duds during the January 1942 attack near the Ananta Samakhom Throne Hall, while other bombs missed their intended targets and struck markets, bridges or other areas. The Tenth Air Force also conducted a minelaying mission at the Chao Phraya River estuary. These documented misses, duds and mines are relevant to historical desk studies, magnetometer surveys and controlled clearance planning.

FAQ: explosive risk in Bangkok

Which Bangkok locations were repeatedly associated with Allied bombing?

The documented targets and affected locations included Hua Lamphong railway station, Memorial Bridge, Bang Sue Arsenal, the Port of Bangkok, Khlong Toei port, Don Mueang Airbase and Wat Liap power plant. Rama VI Bridge and canal locks near Bangkok were also attacked during 1945.

Were unexploded or otherwise hazardous items reported during the Bangkok raids?

The January 1942 attack near the Ananta Samakhom Throne Hall produced four bombs reported as duds. Bombs also missed intended targets during several raids, and a minelaying mission was conducted at the Chao Phraya River estuary. These records identify historical explosive hazards requiring location-specific assessment.

Territorial coverage

DEMINETEC operates in Bangkok and across Thailand from our French head office (285 avenue Marcel Paul, 83500 La Seyne-sur-Mer, France). We mobilise teams and technical assets to fit each mission: documentary studies, short field surveys, or long-duration clearance operations.

Frequently asked questions about UXO clearance in Bangkok

Which munitions are typically found?

In Bangkok and across Thailand, the most frequently recovered items include artillery shells, hand grenades, landmines, aerial bombs and — in coastal areas — naval mines. Exact typology depends on the site history and is the focus of the prior historical desk study (EHT).

Does French Decree 2005-1325 apply abroad?

French Decree 2005-1325 governs civilian pyrotechnic clearance on French soil. Internationally, DEMINETEC uses it as a best-practice benchmark alongside IMAS (International Mine Action Standards) and the contractual requirements specific to Thailand.

How long does a mission in Bangkok typically last?

Duration varies with surface area, investigation depth and anomaly density. An EHT desk study takes 2-6 weeks, a magnetometric survey from a few days to several months, and active clearance from a few weeks up to multiple years for major projects.

Do you operate underwater?

Yes. Through our subsidiary SEMTEC and the DEMINETEC group, we provide commercial diving, underwater magnetometry and submerged-ordnance neutralisation for ports, rivers, lakes and coastal areas.
