Drill Ship - Tiger -- Designed by Marine Design & Research Institute of China
This drill ship is a full turnkey vessel by carrying out engineering, procurement and construction of each complete vessel. These projects are the first EPC drill ship contracts to be undertaken in China with full intellectual property right in China. These contracts represent the successful phase of a conceptual and detail design carried out joinly by Shanghai Shipyard, MARIC and owner (Opus Offshore). The TIGER drill ships be classed by ABS for worldwide operation. They shall have a displacement of around 43,000 tons with a deck payload capacity 10,000 tons and total variable load capability of approximately 16,000 tons.
They shall be outfitted with the latest diesel-electric power systems, spacious accommodation for 150 peoples and modern safe handling equipment for deck, derrick and moon pool. The drilling systems are rated for 750 short tons with 7,500 psi high pressure mud system. Offline stand building facilities are incorporated.
A complete subsea well control package from Cameron shall be emplyed. The ships shall, initially, be equipped for operation in water depths up to 3,000 feet but the design and construction allows easy upgrade to allow operations in water depths up to 5,000 feet.
These drill ship's design concept describe as follows:
(1) Compact Arrangement
(2) Mooring positioning system
(3) Combination with domestic drilling system and international advantage subsea equipment
(4) Excellent economic benefit and energy saving effect.
