Patent number: 7377412Abstract: A tensioner for deploying a member such as a pipe or cable, such as a sub-sea cable deployed from a ship, comprises an endless track and drive means for driving the track. The track includes a plurality of traction elements mounted thereon for movement with the track. Each traction element includes one or more cushions for supporting the member, and a pair of opposed arms mounted on respective sides of the base of the traction element. One or more of the arms is pivotally mounted for movement between a clamping position and a release position. In an alternative arrangement, four moveable arms are linked in diametrically opposite pairs to move between a release position and a clamping position. Cushions on the arms clamp the member in conjunction with the cushions of the traction element, when the arms are in the clamping position. Guide means are provided to urge the arms into the clamping position to grip the member as it passes through the tensioner.Type: GrantFiled: January 26, 2007Date of Patent: May 27, 2008Assignee: The Engineering Business LimitedInventor: Timothy William Grinsted

Patent number: 7040680Abstract: In a load handling device for use with a load having a lifting attachment, the lifting attachment being so attached to the load that, when the load is suspended by the lifting attachment, the load is free to pivot relative to the lifting attachment about at least one axis. The load handling device engages the lifting attachment raises the load; so that it is suspended by the lifting attachment, and lowers it. The load handling device includes a stabiliser movable between a retracted position in which it is substantially clear of the load and an extended position in which it contacts the load on either side of the said axis to limit or control pivoting movement of the load about that axis. The stabiliser may be moveable by a plurality of hydraulic rams connected in a closed loop system. Restriction of the flow of the hydraulic fluid between the rams acts to damp movement of the load.Type: GrantFiled: July 24, 2002Date of Patent: May 9, 2006Assignee: The Engineering Business LimitedInventor: Timothy William Grinsted

Publication number: 20060078385Abstract: Apparatus for creating a local reduction in wave height comprises a buoyant or semi buoyant top surface portion (20) with drag inducing elements (26) disposed below said portion. The drag inducing elements (26) may be compressible or inflatable and collapsible. The apparatus is especially suitable for temporary usage at a given site, after which is may be transported to another site or stored. The compressible or collapsible nature of the drag inducing elements (26) facilitates transport and storage by minimising the volume of the apparatus when not in use.Type: ApplicationFiled: March 19, 2004Publication date: April 13, 2006Applicant: The Engineering Business LimitedInventor: Michael Watchorn

Publication number: 20050286979Abstract: Offshore structures such as wind turbines, wave machines and tidal stream turbines are mounted in a previously located foundation including a socket. The foundation includes an upper body with a conical inner surface which acts as a guide for inserting a leading end of the structure into the socket. The conical surface also provides a reaction surface for alignment means for setting the vertical alignment of the structure when inserted in the socket. Clamp means are provided supported by an A frame for controlled lowering of the structure into the socket.Type: ApplicationFiled: October 20, 2003Publication date: December 29, 2005Applicant: The Engineering Business LimitedInventor: Michael Watchorn

Patent number: 6849963Abstract: A prime mover for extracting power from moving water is described comprising a body which is caused to oscillate in water by reversing the direction of thrust generated by at least one submerged control member e.g. a hydroplane or rotating cylinder protruding from a side of the body.Type: GrantFiled: May 3, 2004Date of Patent: February 1, 2005Assignee: The Engineering Business LimitedInventors: Timothy William Grinsted, Michael John Watchorn

Patent number: 6731018Abstract: A prime mover for extracting power from moving water is described comprising a body which is caused to oscillate in water by reversing the direction of thrust generated by at least one submerged control member e.g. a hydroplane or rotating cylinder protruding from a side of the body. Preferably, the prime mover comprises an open bottomed tank which when it oscillates alternately compresses and decompresses a fluid inside it between a closed top of the tank and the water surface. Preferably the fluid is air. Other energy removal schemes can be combined with the prime mover to generate power.Type: GrantFiled: October 26, 2000Date of Patent: May 4, 2004Assignee: The Engineering Business LimitedInventors: Timothy William Grinsted, Michael John Watchorn
