Semisubmersible, semisub, and semi are additional terms for a semi submersible structure. A specialised vessel, it can be used for heavy lifting, offshore drilling, producing oil, providing accommodation, or a mix of these tasks.
Production semis are towed to the field and connected to their permanent mooring systems after oil wells are drilled and finished by drilling boats. A drilling rig may occasionally be built into production semis on purpose so that research drilling can continue on the same platform after production has begun. (first oil).
The Global Semi-submersible vessel market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A fresh semi-submersible ship is being developed by COSCO Shipping Company called the Xin Guang Hua. (COSCOL). The Dockwise Vanguard is the world’s biggest vessel of its kind, and the 98,000dwt heavy-lift vessel is a close second.
A steel-cutting event marked the semi-submersible ship’s launch. It is being constructed at the Chinese port in Guangzhou owned by CSSC Offshore & Marine Engineering. Overall, the Xin Guang Hua is 255 metres (837 feet) long and 68 metres wide. (223ft).
The full draught is 10 metres (32.8 feet), the hull depth is 14.5 metres, and the length between perpendiculars is 250.2 metres (820.9 feet). (47.6ft).The ship has a sizable open platform that is 68 metres (208.4 metres) wide and 68 metres (208.4 metres) long. (223ft).
Every 2.4m (7.9ft) along the deck, there are web frames that can support a total weight of 125t and a maximum load of 20t. The vessel can manage both stern and side loading thanks to its improved internal strength design. Large floating structures can be transported on board thanks to its 16 m deck submerging capability.
The heavy-lift craft will be fitted with a diesel-electric propulsion system with a 10,500kW power output. The propelling system also consists of two 2,650kW bow thrusters and two 2,650kW stern thrusters.Additionally, a Class 2 dynamic positioning system and two fixed pitch propellers will be part of the propelling system.
The propulsion and ballast systems are being built with double separate redundant configurations in order to increase the vessel’s safety and dependability.
