Two SWL250T stroke 2500mm Cranemaster units in series were used by Technip USA for cross haul and landing of 167T weight piles, manifolds and pump stations. The structures were installed at 2700m water depth from the Deep Blue at Petrobras America Cascade and Chinook gas fields in the Gulf of Mexico.

For the Gjøa project, Technip made use of a 50T 3000mm stroke Cranemaster for the wet storage and installation of GRP covers at 370 meters water depth. The covers had submerged weights ranging from 4T - 18T, and surface areas from 50m^2 - 250m^2. Cranemaster was in this case used together with active heave compensation, where Cranemaster served as an overload protector.

For a offshore wind farm project off the UK coast, Jumbo Offshore included Cranemaster for installation of transition pieces for offshore wind mills. To limit the lifting height above the ship deck, a custom made "lock and release" system was designed and included in the development of two new 400T 2500mm stroke units for this project.

Cranemaster was mainly used to reduce the crane wire tension and to ensure a safe landing of the transition pieces onto the piles offshore.

For the QLS (Quick Lift System) Project, Technip made use of Cranemaster to avoid reentry when lifting a platform structure from a barge onto the platform. 2pc 400T 4300mm stroke Cranemasters with custom made quick lift system.

When  lifting the loading buoy into the ships docking bay the ships movement can give high peak loads on the lifting gear. To dampen and avoid these excessive loads Ernst-B. Johansen AS designed a special Cranemaster which is permanently installed in the top of the loading buoy as an over load protector. The Cranemaster will stroke as the load exceeds the preset pressure in the Cranemaster. This ensures a smooth and safe docking of the loading buoy.

Cranemaster is installed in APL loading buoys on the Vincent and Reliance fields.

 The vessel “Normand Seven”  was chartered from Solstad Offshore ASA  by Subsea 7, one of the world’s leading subsea engineering and construction companies, and converted into a subsea pipe laying vessel for a long-term contract in Brazilian waters. Subsea7 looked into ways to dynamically test the flexible pipe tensioner installed on the vessel and a standard Cranemaster rental unit available from stock was chosen as an affordable, convenient and safe solution for this operation.

 A SWL 400T 4300mm stroke Cranemaster was attached to the vessels’ stern and a wire was run from the Cranemaster to the a test pipe hold by the pipe tensioner. The pipe was then run  out and in of the tensioner to test that it could work under max work load. To increase the load on the wire which was retained by the cable tensioner, the Nitrogen pressure in the Cranemaster was simply increased.  If the cable tensioner should break down or the wire snap, the only thing that would happen was that the piston rod would safely return to zero stroke. When the load test was finished the Nitrogen pressure was released and the unit hooked of.
