Strategic Location
Our STS anchorage is positioned west of Pulau Bunting, District Yan, Kedah, a prime maritime location along the Straits of Malacca, offering significant advantages over other anchorage points.
Naturally deep waters, with a draught above 30m, coupled with very stable waves and wind conditions year-round, ensure safe and secure STS operations. Located just 10-12 nautical miles from shore, the site is ideal for facilitating the swift movement of equipment, pilots, and crew. This proximity also enhances operational efficiency by reducing transit times and minimizing risks.
By choosing SWO’s STS anchorage points, operators benefit from faster, cost-effective, and strategically positioned maritime services, reducing overall operational delays and costs.

This location provides:
Less Traffic Congestion
Unlike the heavily congested areas around Port Klang and Singapore, our anchorage offers a safer and faster STS transfer environment, reducing waiting times and optimizing vessel turnaround.
Expedited Transfers & Bunkering
The low-traffic nature of our designated anchorage allows for faster and more efficient STS operations, ensuring vessels save time and costs compared to busier alternatives.
Safe & Secure Anchorage
With well-regulated maritime operations, our anchorage provides a stable and secure environment for STS transfers, offshore bunkering, and vessel support services, ensuring full compliance with international maritime safety standards.
Reduced Need for Southbound Diversions
Vessels avoiding the need to sail south to Port Klang or Singapore for STS services can significantly cut fuel costs and transit time, improving overall operational efficiency.
Strategic Positioning for Regional & Global Routes
Located at a crucial midpoint in the Straits of Malacca, our anchorage provides convenient access for vessels transiting between the Indian Ocean, the South China Sea, and key regional ports.
