PT. Samudra Marine Indonesia

What PT. Samudra Marine Indonesia does

PT. Samudra Marine Indonesia (SMI) is an integrated shipyard located in Bojonegara, Serang, Banten, Indonesia, founded in 2013 and operating with approximately 372 employees. The company delivers three core services — ship repair, shipbuilding, and ship recycling — to Indonesian and Southeast Asian shipping lines and ship owners, handling a wide range of medium-sized commercial vessels including container ships (5,000–30,000 DWT), bulk carriers (up to 40,000 DWT), tankers (including bitumen and 3,500 MT new-builds), tugboats, barges, dredgers, and passenger ferries. SMI's facility footprint includes the MURI-record 320m x 55m Dock SAM, the 280m x 45m Dock SBS, a 215m x 35–40m BAM-SMI dock, two additional new graving docks (Dock 5 and Dock 6), 4 x 40 MT jib cranes, 300m + 500m of jetty berthing, and a 40,000 m² bonded new-build yard capable of constructing six barges simultaneously.

The underlying technology stack centers on conventional heavy-industrial shipyard equipment rather than digital or AI systems: CNC machining, plate bending and rolling, automated shot blasting and painting, slipways, and airbag-based vessel launching. Onshore workshops support steel fabrication and precision component manufacturing. SMI holds ISO 9000 (quality), ISO 14000 (environmental), and OHSAS 18000 (occupational health and safety) certifications, and the bonded yard enables duty-deferred construction for export builds.

SMI's business model is project-based and direct-to-customer: pricing is bespoke per vessel and scope, with no public pricing, no intermediaries, and sales conducted through dedicated project managers engaging ship owners directly. Revenue is generated from one-time repair contracts (200+ vessels repaired in 2012) and new-build deliveries (20+ vessels planned for 2013), plus ancillary marine and workshop services. The company operates within the SAM Group alongside related entities PT Sumber Gunung Maju (SGM) and PT Batu Alam Makmur (BAM), and distribution is essentially a single physical shipyard site serving domestic and regional customers via direct enterprise sales. Geographic expansion into Malaysia is indicated, but the bulk of customers remain Indonesian shipping operators concentrated in Surabaya, Medan, Kalimantan, and Pasir Gudang.

Direct peers

• PT Dumas Tanjung Perak Shipyard: Mid-sized Indonesian shipyard in Surabaya providing ship repair, shipbuilding, and marine services. Comparable to SMI in scale, geography, and service mix, with similar focus on Indonesian and Southeast Asian commercial vessels.
• PT Adiluhung Saranasegara Indonesia: Indonesian shipyard focused on ship repair and shipbuilding of medium-sized commercial vessels, including tankers, tugs, and barges. Direct peer in vessel type, customer base, and yard size, competing with SMI for the same Indonesian domestic shipping customers.
• PT Dok dan Perkapalan Kodja Bahari (Jakarta): Historic Indonesian ship repair and shipbuilding group operating shipyards in Jakarta and across Indonesia. Most directly comparable to SMI in terms of business model (repair + new-build + ancillary services) and customer base (Indonesian domestic shipping lines).

Broad incumbents

• PT PAL Indonesia (Persero): Indonesia's largest state-owned shipbuilder, operating in Surabaya with capabilities spanning naval and commercial shipbuilding as well as ship repair. Directly comparable to SMI as a domestic Indonesian shipyard serving similar vessel types and end customers, though considerably larger and more diversified across defense and commercial segments.
• Sembcorp Marine: Major Singapore-listed shipyard and offshore engineering group operating multiple yards (Tuas, Admiralty, Jurong). Competes with SMI in the regional repair and offshore-support new-build market, but at significantly larger scale and broader portfolio.
• Keppel Shipyard: Singapore-based shipyard group and offshore engineering heavyweight. While operating at a much larger scale and offshore-energy focus, Keppel overlaps with SMI in commercial ship repair and medium-sized vessel new-build services in the Southeast Asian market.
• Vietnam Shipbuilding Industry Corporation (Vinashin / SBIC): Vietnamese state-owned shipbuilding and repair group with multiple yards across Vietnam. Comparable to SMI in core service offerings (repair and new-build of commercial vessels) and regional Southeast Asian customer base, though at considerably larger group scale.

Regional players

• ASL Shipyard (Singapore): Singapore-based shipyard providing shipbuilding, ship repair, and offshore engineering services. Comparable to SMI in service mix (repair + new-build) and Southeast Asian customer base, though operating at higher scale and cost base.
• PT Krakatau Engineering: Indonesian engineering and fabrication firm with marine and ship repair capabilities at Cilegon, near SMI's Banten location. Comparable for local ship repair and fabrication services, though its primary focus is broader industrial engineering.
• Pan United Shipyard (Vietnam): Vietnamese shipyard providing ship repair and shipbuilding for ASEAN and international customers. Comparable to SMI in new-build of barges and small- to mid-sized vessels, though with a different cost base and geographic focus.
