Key Dive Site Facts
Dive Site Overview
Originally the MV Tung Hwang, the Cement Wreck's history intertwines with Brunei's development. This cargo ship transported cement supplies from Taiwan, destined for the Sultan’s Istana Nurul Iman construction, tragically striking shallow rocky obstructions in the Samarang Banks.
Though initially surviving the impact, the vessel foundered in Brunei’s waters, settling near the Bluewater Wreck. Measuring 90 meters (295 feet) in length, it now rests upright on the seabed, with prominent kingposts reaching upwards. Its open deck is densely covered in marine growth, transforming into a thriving artificial ecosystem.
Scattered cement bags remain strewn across the deck, gradually integrating into vibrant marine flora and providing additional substrate for colonization. With an accessible maximum depth of around 21 meters (70 feet), the site proves appealing for extended bottom times, offering ample opportunity for thorough exterior exploration.
An intact orientation makes navigation straightforward for divers, revealing different sections of the former cargo vessel.
Best Time to Dive
Divers seeking optimal conditions for the Cement Wreck often target months with calmer seas and clearer visibility. April, May, and June consistently show 'Excellent' dive scores, benefiting from lower average wave heights, typically between 0.32 and 0.48 meters (1 to 1.6 feet), and moderate rainfall averaging 6 to 9.8 millimeters. These months offer a generally more comfortable experience, enhancing both surface and underwater enjoyment. Other periods, from January to March and July to December, are rated 'Good' for diving. During these months, wave heights might increase slightly, up to 0.95 meters (3.1 feet), and rainfall can be higher, reaching up to 11.1 millimeters. Air temperatures remain consistently warm year-round, ranging from 27-28.5°C (81-83°F). Water temperatures typically mirror the tropical air, ranging from 27-29°C (81-84°F), providing comfortable diving throughout the year.

Dive Experience & Conditions
An open-sea environment surrounds the Cement Wreck, introducing a dynamic interplay of currents and surge. Constant pounding from these forces contributes to reported superstructure fragility, emphasizing the need for cautious approaches during any potential penetration attempts. Visibility at the site is fortunately often clear, enhancing the wreck's dramatic underwater scenery, allowing for comprehensive views of its structure. Light filters through broken hull sections, creating an atmospheric feel appreciated by photographers seeking evocative wreck shots. Resting at approximately 21 meters (70 feet), the wreck's depth is ideal for prolonged dives, allowing ample time to observe detailed coral growth and resident marine life. An upright MV Tung Hwang, with prominent kingposts still reaching towards the surface, provides a clear structural outline for diver navigation across its main deck.
Dive Difficulty & Safety Guidelines
For a safe and rewarding experience at the Cement Wreck, adherence to specific guidelines is paramount. Strict entry for advanced-level divers requires proof of a minimum of 50 logged dives prior to booking. Qualified divers considering penetration must exercise extreme caution due to superstructure fragility and the constant pounding from open-sea currents and surge. Advance booking of at least three days is required; trips operate with a minimum of four divers and a maximum of ten. Always dive within your training and experience limits, and be mindful of buoyancy to avoid contact with delicate coral growth and the deteriorating wreck structure.
