Sealink International Berhad

What Sealink International Berhad does

Sealink International Berhad is a Malaysia-domiciled, Bursa Malaysia Main Market-listed integrated offshore marine services provider headquartered in Miri, Sarawak. Founded in the mid-1970s by Yong Foh Choi and entering the oil and gas sector in 1994, the company operates across more than 20 countries spanning Southeast Asia, the North Sea, West Africa and Australia. Its core customer base is global offshore oil and gas exploration and production operators, served through long-term and project-based charter contracts.

The business is organized around four service pillars: ship ownership and chartering of a fleet of approximately 30 vessels (AHTS, PSV, landing craft, multi-purpose vessels, tugs, seismic support vessels, barges and accommodation barges); in-house shipbuilding at shipyards in Miri and Kuala Baram operated by Sealink Shipyard Sdn Bhd and Sealink Engineering and Slipway Sdn Bhd; maintenance and repair services delivered through Sealink's regional facilities; and specialized bollard pull testing at a facility in Sipitang, Sabah. Technically, the fleet emphasizes deepwater-capable assets including 12,000-bhp AHTS vessels with Kongsberg K-POS DP-2 dynamic positioning, hybrid diesel-electric propulsion, 150-tonne bollard pull capability, variable frequency drive thrusters and 'Green Ship' environmental classification, with newer hulls built at Jiangsu Zhenjiang Shipyard in China.

Revenue is generated primarily through vessel charter contracts (typically multi-year engagements with enterprise-scale O&G operators), one-time build-and-deliver contracts for new vessels, and recurring maintenance/repair and bollard pull testing fees via the wholly-owned subsidiaries, including Seagood Pte Ltd in Singapore. Pricing is custom and quote-based rather than publicly disclosed. The company goes to market via direct enterprise field sales to O&G operators, complemented by investor relations activity as a Main Market-listed entity and selective industry event participation. Customer concentration is driven by a relatively small number of major O&G operators running multi-year charters; specific named customer logos are not disclosed in the input material.
