Vizhinjam International Seaport Thiruvananthapuram

Vizhinjam International Seaport Thiruvananthapuram (/vɪzɪnˈdʒæm ... ˌtɪrʊvənənˈtɑːpʊrəm/ ^ⓘ, VIZ-in-jam ... TIR-uu-və-nə-TAH-puurr-əm), also known as Port of Trivandrum is India's first deep-water transshipment port. Located in the city of Thiruvananthapuram, the port is designed to be a multi-purpose, all-weather, green port and is about 19 kilometres (12 mi) from Thiruvananthapuram International Airport. It is India's first automated port, and its only port directly adjacent to an international shipping lane. The port is 10 nautical miles (19 km; 12 mi) from the heavily-trafficked east-west shipping channel connecting Europe to the Persian Gulf, Southeast Asia, and the Far East (Suez–Far East route and Far East–Middle East route). The port has a natural depth of 24 metres (reducing the need for dredging) and can host many of the world's massive cargo ships, including those exceeding 24,000 TEU such as ULCS container ships. The port was inaugurated by Indian Prime Minister Narendra Modi on 2 May 2025.

The port's breakwater is India's deepest, reaching a depth of 28 metres (roughly equal to the height of a nine-storey building. The largest vessel to dock at the port is the MSC Türkiye (399.99 metres long and 61.3 metres wide, with a capacity of 24,346 TEU); the highest TEU movement on a single vessel was 10,576 TEU on the MSC Paloma. A cruise berth is under construction along the breakwater for cruise ships. When fully commissioned, the port is expected to be capable of accommodating 50 percent of India's container transshipment currently handled at Dubai, Colombo and Singapore. The project's first phase cost ₹8,867 crore (US$1.0 billion or €930 million); and the remaining phases cost ₹20,000 crore (US$2.4 billion or €2.1 billion).

The port's location, near the southern tip of the Indian coast, provides access to other Indian ports on the eastern and western coasts. Its breakwater extends 7.5 metres above the waterline and 22 metres below. The breakwater is 3.1 kilometres long, and will be extended to 4.5 kilometres in the port's final phase. The STS Super Post-Panamax crane, with an outreach of 72 metres, a back reach of 20 metres, a rail gauge of 35 metres and a lifting height of 74 metres, is India's tallest STS crane. A rail connection planned for Vizhinjam Seaport will include the construction of India's third-longest rail tunnel. The port, owned by the government of Kerala, will be operated by the Adani Group for 40 years.

Vizhinjam International Seaport is expected to compete with international ports such as Colombo in Sri Lanka, Salalah in Oman, Port of Jebel Ali in Dubai and Singapore Port. Its construction has three phases, with the first phase expected for completion by September 2024. It is proposed to follow the landlord-port model, accommodating passenger, container and other cargo shipping.
