The present invention relates to a tensioner pad assembly (230) for a track-type tensioner, comprising : - a mounting support (32) ; and - a tensioner pad (34), mobile relative to the mounting support, said tensioner pad comprising a contact surface (52) extending parallel to a first axis (X), said contact surface being able to get into contact with a pipe-like device. The tensioner pad comprises a central segment (40) and a first (42) and a second (44) lateral segments, each of said segments comprising a surface part of the contact surface of the tensioner pad, each of said central and lateral segments being translatable (236) relative to the mounting support along a translation axis (Z), perpendicular to the first and second axes.

A system (20) for laying flexible product (10) from a storage area (22) below a deck (13) of a vessel includes an inline quadrant (28) above the deck (13) for guiding cable (10) to a portside or starboard side of the vessel. The cable can enter the inline quadrant (28) from either a portside and a starboard side. The system further includes a highway (27) with a highway portside guide (29) and a highway starboard side guide (31) for guiding the flexible product (10) from a below deck position to an above deck position on either the portside or the starboard side; and a movable spooling system to guide flexible product (10) between the storage area (22) and to either the portside guide or the starboard side guide of the highway (27). The highway (27) extends to the portside entrance and the starboard side entrance of the inline quadrant.

A tensioner pad assembly is adapted to be mounted on an endless track of a tensioner to frictionally clamp an elongated product supported and moved by the tensioner. The pad assembly includes a carrier member and a pair of gripping members, which gripping members can with their carrier member mating surfaces be mounted in multiple discrete gripping positions on gripping member mating surfaces of the carrier member. The mating surfaces form interlocking structures adapted to transfer a squeeze force from the carrier member to the gripping members. The interlocking structures provided on the carrier member define the multiple discrete gripping positions. The gripping member mating surfaces extend at an angle relative to each other, such that the multiple discrete gripping positions differ in their distance to the base portion as well as in their distance to the imaginary plane of the carrier member.

A method for determining start and stop times of at least one selected operation on a pipe deployment vessel includes measuring either or both tension on a pipe deployed from a reel on the vessel and velocity of pipe motion with respect to the vessel. Rotational velocity of the reel is measured. Geodetic position of the vessel with respect to time is measured. The start and stop times of the at least one selected operation are determined from the measured tension, motion velocity, rotational velocity and geodetic position. The start and stop times are recorded.

The present invention relates to a marine pipelaying vessel for S-lay pipelaying an offshore pipeline and integrating one or more accessories into the pipeline, and a method for S-lay pipelaying wherein use is made of such a vessel. The vessel according to the invention comprises a hull (1) having a stinger end and a stinger (20) for guiding the launched pipeline in a curved pipeline trajectory, which stinger is pivotably connected to the hull, and an accessory handling J-lay tower (30) at the stinger end of the hull. The J-lay tower allows the pipeline and connected accessory to be laid in J-lay mode while connecting further pipe sections to the pipeline at least until the accessory has been lowered past below the retracted stinger. A stinger support assembly (15) is provided for supporting the stinger in a pipelay position, and for allowing movement of the stinger between the pipelay position and a steep downwardly pivoted retracted position by pivoting the stinger about its stinger pivot axis, wherein the stinger in the retracted position is away from the J-lay firing line.
