The range of fibre rope cranes up to 400t combines our field-proven expertise in equipment employing braided fibre ropes in deepwater offshore operations with our offshore crane technology and control systems. Fibre rope cranes retain their full rated capacity down to maximum working depth, whereas a wire crane must be derated due to the weight of the steel wire. At more than 2,500 metres a 250t fibre rope crane can do the same work as a 400t steel wire crane. The reason is that the braided fibre rope has approximately zero weight in water, whereas with wire the useful lift decreases with depth because of the suspended weight of the wire. Lower crane weight place less demand on ship stability, and also enables the option of using a smaller vessel for the same operation. Fibre rope handli...
Friendlier for you and for the Earth - delivering environmental and functional benefits from a smaller, improved hydraulic system and accurate, integrated electric winch drive system
Heavy lift construction vessel HLCV Borealis (now known as Seven Borealis) is being built by Sembawang Shipyard, in Singapore. Hull fabrication was done at the Nantong Yahua Shipyard. The crane vessel, which is owned by Subsea 7, was delivered in early 2012. "Designed by Sea of Solutions, the Seven Borealis is based on the design of the SOC 5000 heavy lift crane vessel." Seven Borealis is designed to be used for a range of operations, including platform installation, deck installation, spar deck installation, mooring installation, subsea installation and platform removal.Nordic Heavy Lift placed the order for the vessel in June 2007. The keel was laid at the Nantong Yahua Shipyard in November 2008. The hull was launched in October 2009 and had arrived at Sembawang Shipyard by November 2009...
Vortex, http://www.cm-labs.com, training simulator exercise using two 100T knuckle boom cranes on intervention vessels to lift a subsea template from a barge and place on the seabed. Vortex offshore crane simulators contain many training exercises to build highly skilled offshore lift crews.
The 50t @ 26m @ 600m depth aCTIVE hEAVE cOMPENSATED subsea crane designed according DNV 2.22 and EN 13952-1 normS, is the last big offshore crane produced by Sormec Italy. M4500/EL will be integrated onboard BP Subsea Construction Vessel Khankendi built by Baku Shipyard (BSY) and KEPPEL Singmarine (KSM) joint-venture. in Azerbaijan.
ALE present a lightweight modular lifting solution for offshore and subsea operations, which has been designed as a certified offshore crane.
The P12 pipeline from the Troll gas field to Kollsnes is the third gas import pipeline from Troll to Kollsnes. A 36" spool has been installed between the P12 pipeline termination and the subsea 'swan neck' riser outside Kollsnes. The spool was installed in 2011, in one piece and the total length was 155m. The P12 spool was transported to the field by using a barge and installed on the seabed by using the main crane on the DSV Skandi Arctic. The spool was connected to the P12 pipeline and the riser by a welded tie-in using the Pipeline Repair System to perform the hyperbaric welding. The subsea installation and operation of the PRS welding spread was performed by saturation divers from the DSV Skandi Arctic, managed by Technip Norway.
Sonardyne's Wideband systems reduce risk by providing highly accurate positioning the installation of subsea structures in water depths up to 7,000 metres.
YMV double drum towing winch specifically designed for Arena Offshore Supply Vessel; one drum for 20 t Aframe (anchor handling and subsea operations), other drum for 20t towing winch. YMV Offshore Telescopic Boom Crane 3,5t @8 mt - 1,6t@16mt is the custom made solution for this project to effective use of deck area.
Vortex, http://www.cm-labs.com, simulating a Hydralift knuckle boom crane on an intervention vessel. The crane is lowering a template to the seabed. Active heave compensation is used as the load approaches the seabed. Heavy equipment simulations using Vortex feature precise emulation of actual machines and vehicles, including drivetrains, wheels, tracks, booms, and cable systems based on exact engineering specifications.
