4 A multi-purpose, deepwater pipelay and heavy lift vessel Pipelay equipment The rigid S-Lay pipelay system is designed around a conventional central firing line layout, optimized to maximize production of welded pipelines offshore. The firing line of 11 stations is designed primarily for single joint installation (12.2m joint lengths) but is able to conduct double joint production if required. Equipped with four 125 Te tensioners giving a maximum of 500 Te top tension, the vessel is also capable of handling in-line structure installations. With the mass storage of pipe on the main deck, the vessel is fitted with high capability support rollers and conveyors to safely transport the pipe joints into the firing line for uninterrupted production. Recently installed production tracking software provides real-time data for monitoring purposes. Stowage capabilities The G1200 has a large, 2,800m 2 multipurpose deck with storage facilities for up to 3,500 Te of pipe. It is also capable of supporting structures and various installation spreads for a range of operations. To improve the efficiency of operations offshore, the 10 Te/m 2 loading capacity allows storage of large packages of project-specific equipment during transits. Stinger capabilities The 97 meter long, 3-section, Deep Water Stinger is designed to accommodate a fixed range of pipe catenaries to improve high strain over bend profiles, maximizing the vessel s capability to execute pipelay in a variety of sea state conditions and water depths. The vessel can also be equipped with a Shallow Water Stinger for project-specific requirements. Abandonment & Recovery system The G1200 is equipped with a single A&R traction winch with two storage winches for 108 and 64mm wire ropes, giving dynamic tension capacities of 400 Te and 150 Te respectfully. Each system can be utilized for pipelay abandonment and recovery operations through the central firing line of the vessel or it may be utilized for the recovery and installation of subsea structures via the main deck overboarding sheaves on the starboard side. The A&R winches installed beneath the weather deck are fitted with wires as shown below: 400 Te 3,000 m (9,842 ft) / 108 mm (4.25 ) diameter Low Rotation (LR) wire 150 Te 3,000 m (9,842 ft) / 64 mm (2.5 ) diameter LR wire Cranes The G1200 is equipped with three cranes designed to support heavy lift, pipelay, and subsea installations. 2 x 40 Te MSB-12 cranes located on the port and starboard sides of the vessel, with 55 m of reach to service all working areas of the main deck and offshore vessels / barges moored to the G1200. Used for pipe loading and general stores. 1 x 1,200 Te PC-37 Heavy Lift Crane located at the stern of the vessel is designed to support jacket and In-Line Pipelay structure installations. The specifically designed crane is equipped with a 1,200 Te head block (2 x 14 part) for pipe loading and general stores; and a secondary 690 Te block (2 x 8 part) for subsea installations in water 4

5 depths of up to 130 m (426 ft). The Auxiliary Block (350 Te) and Whip Line Block (60 Te) are also capable of subsea operations, improving the vessel s ability to support installations and deployments, and for transfers to the vessel s 400 Te A&R system. The Auxiliary Block has a maximum subsea reach of 93 m (305 ft) and the Whip Line Block can be deployed up to depths of 213 m (700 ft). 60 Te 20 m Remotely Operated Vehicles (ROVs) Pipelay and subsea construction activities are supported by two identical Schilling Ultra Heavy Duty (UHD) advanced work class ROV systems, providing industry leading performance and power. The systems are deployable from the aft main deck of the G1200 over the port and starboard sides. PC-37 Crane Both systems are rated to 4,000 m (13,125 ft) with excursion distances up to 1,200 m (3,937 ft). State-of-the-art manipulators, sensors and tooling are permanently fitted, although clientsupplied tooling is easily interfaced with via dedicated valve packs and hydraulic systems. Each system is powered by a 200 hp Hydraulic Power Unit (HPU) and can accommodate any industry standard work package up to 300 kg payload. The ROVs are operated from a dedicated control van installed on the deck of the vessel with workshops and dedicated stores facilities. 350 Te 17 m Port & Starboard MSB 12 Cranes 1200 or 690 Te 15 m 40 Te 12.5 m 30 Te 8.5 m 22.7 Te 50 m 30 Te 8.5 m 60 Te 93 m 150 Te 85 m 270 Te 70 m 5

6 BOW PORT STBD [knots] STERN DP capability plot Considered available power: 100% thruster capacity Considered current: 1.5 kts Shallow water capabilities The conventional eight point mooring system of the G1200 is designed to allow the vessel to operate in non-dp waters as shallow as 8 m (26 ft). The vessel has the capacity to support beach pull operations and transition to DP pipelay operations. Together with a shallow water stinger designed to support 4 to 60 pipelines, this provides the G1200 with the versatility required of a single source pipelay and construction vessel. Station keeping The main DP control system is a Kongsberg K-Pos DP-22 with K-Pos DP-12 backup system. Two main azimuthing propelling units (2 x main 4.5 MW) are provided aft for propulsion and DP. Additionally, five further retractable azimuthing thruster units (5 x azi 2.4 MW) and one tunnel thruster (0.88 MW) are provided for DP operations. The vessel operates to DP Class 2 (3-way split) during pipelay and heavy lift operations. Navigation / integrated vessel management system (VMS) The vessel is equipped with a Kongsberg K-Thrust for thruster control and conning plus a comprehensive internal and external communications system together with K-Chief safety and alarm monitoring to complete the package. The Kongsberg IVMS System satisfies IMO MCS 645 DP Equipment Class 2 and ABS DP-2 Rules for DP system redundancy and integrates the main vessel control tasks through a common communication infrastructure. Machinery / Propulsion The vessel s main machinery consists of 6-off diesel driven (3 off MAN 8L 32/40 and 3 off MAN 9L 32/40) generators (three in each of the vessel s two engine rooms) electrically segregated into three separate, independent systems, providing a total of 24.9 MW generated power to the propulsion, pipelay and other consumers. The vessel is fitted with the required machinery redundancies to exceed all class, statutory and performance requirements. Transit speed The G1200 has a maximum service speed of 12 knots for transit between work locations. Accommodation The G1200 is equipped with modern, comfortable accommodation for 264 personnel. The spacious onboard facilities include fully outfitted hospital and medical facilities, client accommodation, meeting rooms, gymnasium and recreation room with movie theater. The vessel has three Wifi Networks available: client, project and welfare. 6
