NEW MODULIFT SUBSEA SPREADER BEAMS CONFORM TO REVISED DNV STANDARD
Conforming to the revised standard, Modulift has launched a new nautical series of spreader beams for subsea environments, designed to safely lift weights of up to 500t. Unlike standard spreader beams that are manufactured using circular hollow sections, the subsea range has an open section design, suited to water submersion by eliminating
Modulift, a manufacturer of spreader beams, lifting beams and other below-the-hook equipment, has timed the launch of its subsea modular spreader beams to coincide with publication of a revised offshore standard from DNV GL AS, titled DNV-OS-H206, that references the use of spreader bars. DNV, formerly known as Det Norske Veritas AS, a global provider of knowledge for managing risk, has updated the standard that covers loadout, transport and installation of subsea objects.
This is a new document in a series replacing the DNV Rules for Planning and Execution of Marine Operations (1996/2000). The standard replaces Pt.2 Ch.6.
Extensive revisions have been made and three new sections have been added: loadout and transport; subsea lifting; and installation of pipelines, risers, cables and umbilicals.
Excerpts from ‘Section 5—Subsea Lifting’ read, ‘Subsea lifting is defined as installing, moving or recovering an object subsea by means of a crane or other lifting appliance.’ And, ‘The lifted object shall be documented as having adequate stability when lowering through the wave zone.’ It also directly references spreader bars.
the risks associated with cavity or pressure issues. They are finished with a three coat paint system that is based on a two pack epoxy paint combination suitable for the marine environment.
Sarah Spivey, Managing Director of Modulift, said: “We have taken the concept behind the unique modular elements of our highly successful, standard and heavy spreader beam ranges, and have produced a versatile and efficient collection for deep water lifting that also conforms to the latest documentation and standards.”
As with regular spreader beams, they are fully and correctly assembled when combined with the recommended end units, drop links and shackles top and bottom, that also allow for the option to use ROV shackles where necessary.
Spivey added: “The new subsea modular spreader beam range is another example of our engineering expertise presenting an economical below-the-hook solution that allows products to be used time and again, in multiple applications. As is consistent with all Modulift products, the modular design facilitates easy transportation.”
The new nautical series is available to order, while the engineering team is prepared to discuss custom solutions and special requirements.
MODULIFT LAUNCHES TRUNNION MODULAR SPREADER BEAM FOR HEAVY LIFT APPLICATIONS
The new Trunnion spreader beam is set to revolutionise the rigging industry by offering lifting professionals an efficient, lightweight and economic below-the-hook solution.
Modulift, a manufacturer of spreader beams, lifting beams and other below-the-hook equipment, has launched the product primarily to ease the attachment of slings when rigging heavy lifts.
The game changing Trunnion Modular Spreader Beam offers a myriad of benefits to high capacity lifting operations, including significant time savings when compared to similar applications using standard rigs below the hook, taking only half the duration in the rigging up phase, tests suggest.
A trunnion is defined in engineering as one of a pair of
projections attached to opposite sides of a container to provide a support about which it can turn in a vertical. Practically, the Modulift spreader has been modified and a drop link removed to make way for the trunnion pin and cross pins. This allows for direct connection of slings to the spreader beam.
The trunnion spreader will initially be launched in three sizes; MOD250, MOD400 and MOD600, covering a range of capacities from 250t to 1,000t.
The shackle-less solution is in essence a standard modular spreader, using the same struts and bolting configurations and is, thus, fully compatible with current and legacy equipment.
Sarah Spivey, Managing Director of Modulift, pointed to other features of the trunnion modular spreader beam, including improved safety, given there are no heavy shackles and drop
