Description

This is a new build and can be ready for delivery within 3-4 months signing.
The Unit is a self-propelled, self-elevating unit designed and built for the offshore oil field service at the operation water depth of 5~60m.
The hull of the Unit is rectangular box-type structure. The main dimension of the hull to be 63.6 m in length, 40.0 m in width, and 5.8m in depth.
The Unit has 4 cylindrical legs, each fitted with a square shaped spud can at its lower end. The leg length to be 90m (excluding the spud can).The dimension of each spud can to be 11.7m in side length and 1.5m in height.
Four (4) sets of hydraulic-rack & pinion jacking system are equipped for lifting or lowering the Unit.
The main hull has three deck levels which are the double bottom, lower deck and main deck. The main deck is divided into two parts which are the living quarter and free deck. The free deck area of the Unit is around 1500m2.
The Unit is equipped with two rudder-propeller systems driven by main diesel engine and one bow thruster driven by electrical motor. The Unit is equipped with DP1 system. The Unit is also equipped with one 190t main crane and one 20t auxiliary crane for the offshore services.
The Unit has two (2) sets of electric anchor windlass.
The living quarter of four levels is arranged on the main deck at the fore part of the Unit for the accommodation of 300 persons. The jacking control room and the mast is arranged on the top of the living quarter. The helideck is located at the front of the living quarter with diameter of 22.2m to be suitable for landing Sikorsky S-92.
