A support vessel owned by Malaysian firm Vantris Energy passed through the Strait of Hormuz, becoming the fourth ship linked to Malaysia to transit the waterway since the outbreak of the US-Iran war, reported Reuters.

LSEG shipping data showed the Sapura 1200 transited close to the Iranian coastline before entering Muscat port in Oman. The vessel was among seven ships Malaysia sought clearance for from Iran after the strait was largely closed following the conflict's outbreak in late February.

Prime Minister Anwar Ibrahim said in March that Iran had agreed to allow Malaysian vessels passage after talks with officials. Authorities confirmed the ships included those owned by Vantris, MISC Berhad and state energy firm Petronas.

Other Malaysian-linked vessels cleared so far include the Liberian-flagged VLCC Serifos, which exited the strait on 10 April and discharged Saudi and UAE crude at Malacca on April 30.

Another VLCC, Ocean Thunder, chartered by a Petronas unit, passed through on carrying 1 million barrels of Basrah Heavy crude, which was discharged at Pengerang on 18 April.

A third vessel, Mihzem, carrying Qatari liquefied natural gas and managed by an MISC unit, transited under an arrangement involving Iran and Pakistan, becoming the second LNG cargo to cross since the war began.
