Patent number: 9227701Abstract: A vessel has a hull, a contact area at the hull near keel level for attaching to a structure, a lifting device and a lifting cable attached thereto and extending along a heave compensating member. The lifting cable extends along a substantially vertical lifting trajectory to a connect position below keel level. The heave compensating member includes a guide element for guiding the lifting cable and which is connected to a displacement device. The heave compensating member includes a compensator arm with a pivot end pivotally connected to a pivot point on the vessel at a predetermined transverse distance from the lifting trajectory, the cable guide element being attached to a free end of the compensator arm at or near the lifting trajectory, guiding the lifting cable in the direction of the pivot point, the arm being at or near the free end connected to the displacement device.Type: GrantFiled: August 8, 2013Date of Patent: January 5, 2016Assignee: SINGLE BUOY MOORINGS INC.Inventors: Wilhelmus Coenradus Johannes Jozephus Woldring, Peter Alan Lunde

Publication number: 20150122167Abstract: A turret mooring system (1) is arranged on a vessel for receiving a mooring buoy (6). The turret mooring system includes a turret mooring structure (3) with a receptacle for the reception of the buoy, and at least one structural connector (10). The at least one structural connector secures the turret to the mooring buoy which is provided with at least one buoy locking system (7) for locking the mooring buoy (6). The buoy locking system is arranged with a base mount that connects the structural connector to the vessel. The base mount is arranged as an adjustable element for adjustment of the connection between the at least one structural connector and the vessel.Type: ApplicationFiled: April 29, 2013Publication date: May 7, 2015Inventors: Peter Alan Lunde, Bram David Weisman

Patent number: 8231420Abstract: A submersible mooring buoy for a floating vessel comprises a compartmented hull; a plurality of non-buoyant, catenary anchor lines each connected to the hull and a spring buoy such that the hull may be submerged without sinking to the seafloor by flooding selected compartments; and, a plurality of mooring legs anchoring each spring buoy to the seafloor.Type: GrantFiled: May 26, 2011Date of Patent: July 31, 2012Assignee: Seahorse Equipment Corp.Inventor: Peter Alan Lunde

Publication number: 20110193340Abstract: A flexible pipe joint achieves flexibility between pipe sections using a plurality of elastomeric pads arranged to create a spherical acting joint. The angle of the pads (and resulting radius of the sphere) can be selected to optimize the internal loads and relative motions of the mating parts. The use of the flex joints reduces bending moments in the pipe from vessel motions and current loads. Stability of the assembly may be maintained by having sufficient weight on the lower sections of the riser to resist current loads. A soft elastomeric seal minimizes fluid loss and allows relative motions of the pipe at the joint. The connector may be mated by inserting the inner pipe into the outer pipe and then rotating the pipe sections relative to each other until a stop is reached. A separate latch may be set, or automatically set, to prevent reverse rotation and unlatching.Type: ApplicationFiled: February 8, 2011Publication date: August 11, 2011Applicant: Seahorse Equipment Corp.Inventor: Peter Alan Lunde

Patent number: 3982402Abstract: This invention relates to a method and to an apparatus for use in laying a submarine pipeline from a pipe-laying vessel. According to one aspect of the present invention, there is provided a reel pipe-laying method for continuously laying a pipeline of up to 24-inch diameter without a stinger by (1) aligning a pipe portion as it is being paid out from the reel, (2) straightening the aligned pipe portion, (3) tensioning the pipe, (4) discharging the straightened pipe under tension into the body of water, and (5) changing for different water depths and pipe conditions the lift off angle of the pipe relative to the horizontal by pivoting a diverter about a horizontal pivot, the diverter supporting at least the straightener and the tensioner and extending from the horizontal pivot mounted near the aft end of the vessel, upwardly toward the reel.Type: GrantFiled: May 5, 1975Date of Patent: September 28, 1976Assignee: Santa Fe International CorporationInventors: Alexander Craig Lang, Peter Alan Lunde
