태국은 2017년 중국에서 041형 원급 잠수함에 기반한 S26T 잠수함 구매 계약을 3억 8천만 달러 규모로 체결했습니다. 그 당시엔 MTU 396 디젤엔진을 탑재할 예정이었는데 EU의 제재로 인해 중국 수출이 차단돼 잠수함의 미래가 불투명했었는데, 중국 측에서 자국산 엔진인 CHD620 해상용 디젤엔진으로 변경하자는 제안을 했다고 하네요.
태국 해군의 기술 실무단이 9월 중순까지 CHD620 엔진을 검토중이며 테스트를 통과하지 못한다면 계약을 취소하고 보상이나 환불을 요구할 수 있다고 합니다.
MTU396은 16기통 V형 디젤엔진으로 회전수는 1940RPM, 보어 직경은 165mm, 피스톤 스트로크는 185mm입니다. CHD620은 L6, V8/V12/V16 디젤엔진으로 회전수는 1500~1860이네요.

Model of S26T submarine.
The Royal Thai Navy (RTN) is considering the use of Chinese-made marine diesel engines for its Type S26T diesel-electric submarine programme, which is being led by the China Shipbuilding & Offshore International Company (CSOC).
RTN spokesperson Vice Admiral Pokkrong Monthatphalin said in a 9 August statement that CSOC has offered to replace the originally proposed German-made MTU 396 diesel engines – which were offered when the order was made in 2017 but subsequently blocked from export to China by Berlin in accordance with longstanding European Union (EU) sanctions – with locally built CHD620 marine diesel engines.
VAdm Pokkrong stated that the RTN had requested more information on the CHD620 engines after CSOC proposed the alternative option in June, and has given the company till mid-September to submit the requested data. “The RTN has assigned a naval technical working group to consider these details,” he said. “CSOC is required to submit additional information by 15 September for further consideration.”
“If the substitute [engine] cannot pass the test, the navy could end the contract and seek compensation or refunds,” VAdm Pokkrong added.
In May 2017, Thailand signed a $380 million contract to procure the Type S26T through an agreement with CSOC, the international trading arm of the state-owned China Shipbuilding Industry Corporation (CSIC). The S26T is a modified version of the Yuan-class (Type 041) submarine in service with the People’s Liberation Army Navy (PLAN).
A steel cutting ceremony for the submarine was held in September 2018, and the boat’s keel was laid down in 2019. Work is currently ongoing at CSOC’s Wuchang Shipbuilding subsidiary in Wuhan and the boat is expected to be delivered between 2023 and 2024.
The RTN earlier secured approval from the House of Representatives to procure two additional S26T submarines, despite earlier indications that the acquisition could be deferred due to the economic challenges wrought by the Covid-19 pandemic.
According to company specifications, the S26T submarine displaces 2,550-tonnes at full load and measures 255 feet (77.7 metres) in length and 28ft (8.6m) in beam. The boat can be operated by a standard crew complement of 38 personnel, although it also features a large accommodation space with 46 bunks as well as a separate commanding officer’s quarters, which enable all crew members to have their own berthing space for increased comfort during extended missions.
CSOC also quotes a maximum underwater speed of 17 knots (31 kilometres per hour), dive depth of up to 984ft (300m), and an operating range of over 260nm (481km) on battery power. The boat is also claimed to offer a maximum endurance of 65 days at sea and can transit distances of up to 8,000nm (14,800km) when alternating between surface and underwater cruising.

첫댓글 솔직히 무기금수로 중국(내수) 잠수함에도 쓰이면 안되는 물건임에도 발전기 핑계로 모르는 척하다가, 제3국 수출에 들어가니까 태클 거는 느낌적 느낌(...)이 드네요.
중국엔 계속 팔고 만만한 태국엔 금수 걸어놨나 보네요. 파키스탄에도 원급 들어갈 텐데 거기엔 어떤 엔진이 들어가는지..

기사를 보니 애초 군사적 필요성보다 정치적 용도로 진행된 사업이란 얘기가 있네요 2014년 육군 쿠데타 이후 육군의 하위 파트너였던 해군이 커미션을 빼먹을 대규모 사업이 필요했다고.
타이만과 안다만 해의 평균 수심이 낮아 (타이만은 평균수심 58m, 최대수심 85m)로 2600톤의 원급 잠수함이 활동하기엔 너무 수심이 얕다고 합니다.
